Double Chocolate Mousse Torte
This fudgy double chocolate mousse torte topped with sweetened cream and raspberries is decadent, delicious, and surprisingly easy to make!
Where do fancy-shmancy desserts fit into your life?
Do you make them? Eat them? Order them at restaurants? Only dream of them? None of the above?
This double chocolate mousse torte is no doubt as fancy-shmancy as they come (well, at least in my simple world). It is incredibly delicious and is easily one of my favorite desserts of all time.
Talk about being a perfect, special Valentine’s Day treat.
I wasn’t actually planning on posting about it today.
I mean, I posted about it a loooong time ago (back in 2010), and since I already gave you a recipe repost this week in the name of White Velvet Sugar Cookies, I thought I’d give you a break.
But, in the end, I couldn’t resist (granted, self-control has never been my strong suit).
Today’s my birthday. The big 3-9 to be exact.
And this very cake – this amazing and decadent and perfect double chocolate mousse torte – is currently sitting in my refrigerator right down the hallway there…and I swear I can smell it.
It’s tempting me with every breath I take.
So I figured, hey, if I’m going to break every self-control rule in the name of indulging in all things double chocolate mousse on my birthday, then you should have the same chance.
Of course, you’ll have to whip this baby up yourself (I can’t guarantee there’ll be any left in my house by the time you read this), but at least I’m coming clean about one of my favorite recipes and giving you the chance to make it ASAP.
This double chocolate mousse torte truly is one of my most-loved recipes ever. If you’ve experienced the deliciousness, you’ll understand why I desperately wanted to tell you about it today.
It’s stood with me through the test of time. While some recipes get posted and shared…and forgotten (sad, but true), this one has not.
I’ve requested it for more birthdays than not over the last seven years, and I make it all the time when we entertain company or want a special Sunday dessert.
A complete show-stopper, this fancy-shmancy dessert might seem intimidating.
But if there’s one thing I want you to come away with today, it is that this is actually a very, very easy dessert to make (the hardest part is washing the few bowls it takes to come together…or maybe waiting for it to chill in the refrigerator; yep, that’s way harder than doing the dishes).
A fudgy, chocolate one-bowl cake batter bakes up in a springform pan creating that wonderfully decadent base cake layer.
And it only gets better (if you can believe it) from there.
While the idea of making chocolate mousse might seem terrifying, stick with me here, because it is shockingly simple.
When I posted the original recipe in 2010, it involved making a chocolate mousse recipe that, while delicious, called for using raw eggs (and several additional steps to whip the egg whites and other things).
Because I knew that some people have an aversion to eating raw eggs, I also included an alternate egg-free mousse recipe. Gosh, I was nicer back then than I am today.
Over the years, as I’ve made this torte dozens and dozens of times, I’ve almost exclusively used that “alternate” recipe – a quick chocolate mousse that calls for whisking melted chocolate and cocoa powder together and then lightening up the whole mixture with a “little” sweetened whipped cream.
The recipe below is basically the same recipe I posted all those years ago, but I’ve replaced that original eggy (for lack of a better term) chocolate mousse with the recipe/method I’ve been using since then.
But don’t panic! If you’ve come to rely and love the original recipe, I’ve included the details in the notes of the recipe, so you can continue to make it the same way.
I know a few of you don’t like it when I take recipes out of the archives and repost with updated ingredients/directions.
When I do this, I always try to make a note of any changes for those that love the original. But usually, the changes are a good thing…and the whole reason I’m reposting the recipe again.
So don’t be mad. Be glad, ok? My goal is for everyone to be glad here. Especially today. No mad people on my birthday, pretty please?
If you get mad, I’ll be inclined to self-medicate with an extra piece of double chocolate mousse torte, and my metabolism ain’t what it used to be, so take some pity on this old girl, will ya?
Just a quick note about pans: this recipe calls for a springform pan.
Can you make it in a traditional cake pan? (A question I get a lot on this recipe and others that call for a springform pan.)
Sure, but just keep in mind that it will be harder to get the slices neat and purty…and if using a 9-inch cake pan, you’ll need one with at least 3-inch sides so the mousse and whipped cream stay put.
I have made this in both a 9-inch and 10-inch springform pan. The 9-inch obviously yields thicker layers, but either will work.
If you are completely undone (like I’m completely undone) by over-the-top, highly chocolate desserts that look like a million bucks and taste even better?
Well, this double chocolate mousse torte is for you.
The fact that it’s stayed a favorite after all these years means it is a keeper. Plus, it can be made ahead of time, which is always a huge bonus, if you ask me.
So no matter where you fall on the fancy-shmancy dessert spectrum, you should definitely start planning when you can make this easier-than-it-looks double chocolate mousse torte.
And when you do, think of me sitting here another year older…and still greatly loving me some double chocolate mousse torte (that’s living proof right there that age brings wisdom; we’ll forget about how age brings a whole lot of other “factors” to deal with).
Alternate Mousse Recipe (if you are looking for the original mousse recipe posted in 2010):
1/2 cup butter, cut into pieces
4 large eggs, separated at room temperature
1/4 cup whipping cream
1 tablespoon vanilla extract
8 ounces bittersweet (not unsweetened) or semisweet chocolate, chopped finely (it is important the chocolate for this mousse layer is chopped finely or it won’t melt completely when added to the warm egg yolks)
1/2 cup sugar
Melt butter in medium metal bowl set over saucepan of simmering water (do not allow bottom of bowl to touch water). Whisk yolks, 1/4 cup cream and vanilla in small bowl to blend. Gradually whisk yolk mixture into bowl with melted butter. Whisk constantly over simmering water until thermometer registers 150°F, about 6 minutes (mixture may appear broken – mine did not but it was very thick like custard or pudding). Remove from over water; add chocolate and stir to melt. Set aside. Beat egg whites and 1/2 cup sugar and a pinch of cornstarch in large bowl to medium-stiff peaks. Whisk 1/4 of beaten egg white mixture into warm chocolate mixture to lighten. Fold in remaining egg white mixture.
Double Chocolate Mousse Torte
Ingredients
Cake:
- 8 ounces bittersweet or semisweet chocolate, chopped (see note)
- 1 cup (227 g) salted butter
- 1 cup (212 g) granulated sugar
- 5 large eggs
- 1 tablespoon vanilla extract
- ¼ teaspoon salt
- ¼ cup (36 g) all-purpose flour
Mousse:
- 2 tablespoons unsweetened natural or Dutch-process cocoa powder
- 5 tablespoons hot water
- 8 ounces (227 g) bittersweet or semisweet chocolate, chopped fine
- 1 tablespoon salted butter
- 1 ½ cups cold heavy cream
- 1 to 4 tablespoons granulated sugar, depending on desired sweetness
- ½ teaspoon vanilla extract
- pinch of table salt
Whipped Cream Topping:
- ¾ cup cold heavy cream
- 2 tablespoons powdered sugar
- Grated chocolate, for garnish (optional)
- 2 cups fresh raspberries, or other fresh fruit
Instructions
- For the cake, preheat the oven to 325°F.
- Lightly grease a 9- or 10-inch springform pan; dust with sugar (optional).
- Combine the chocolate and butter in a saucepan or in a microwave-safe bowl. Melt over low heat (on the stovetop) or on 50% power in the microwave at 1-minute increments, stirring in between.
- Cool the mixture to lukewarm. Whisk in the sugar to combine.
- Add the eggs one at a time, blending well after each addition. Mix in the vanilla and salt. Add the flour and mix until just combined.
- Pour the batter into the springform pan. Bake until the cake just rises in center (a tester inserted into center will not come out clean) and springs back lightly to the touch, 30-35 minutes.
- Cool completely in the pan (the center of the cake may fall slightly). Cover and chill while making mousse.
- For the mousse, whisk together the cocoa powder and hot water in a small bowl; set aside.
- Melt the chocolate and butter together in a microwave-safe bowl on 50% power, stirring often, until smooth (don’t overheat!). Whisk the cocoa/water mixture into the melted chocolate until smooth (if there are little lumps, you can press the mixture through a fine mesh strainer into a clean bowl). Let it cool to room temperature (just slightly lukewarm is fine, too, as long as it isn’t warm or hot).
- In a medium bowl with an electric mixer, whip the cream, granulated sugar, vanilla, and salt at medium speed until the mixture begins to thicken, about 30 seconds. Increase the speed to high and whip until soft peaks form when beaters are lifted (I often use my Blendtec blender to whip cream – only takes a few seconds).
- Using a rubber spatula, fold 1/3 of the whipped cream into chocolate mixture to lighten. Fold in the remaining whipped cream until no white streaks remain.
- Spoon the mousse over the cooled cake. Cover and refrigerate for at least 6 hours or up to 1 day.
- Run a sharp knife around the edge of the pan to loosen the torte if it hasn’t pulled away from the sides of the pan while cooling.
- Release the springform pan sides. Transfer the torte to a platter, if desired (often, I just leave it on the base of the springform pan).
- For the whipped cream topping, using an electric mixer, beat the cream and powdered sugar in a medium bowl until soft peaks form. Spread the whipped cream over the torte. Dust with grated chocolate, if desired.
- Top with raspberries. Chill for up to an hour or serve immediately.

Oh, and for those wondering, I easily made this gluten free by subbing the white flour for gluten-free flour. Since there is so little flour in the cake, I didn’t make any other adjustments and it tasted just as the same as the other times I’ve made it. Yum!
Thanks for letting us know that, Sarah – I just answered a comment (not very well) about the same thing!
Happy Birthday, Girl…I hope it is the finest year ever! (This looks DEVINE~)
Thanks, Lauren! 🙂
Mel, HAPPY BIRTHDAY! My kids tease me about how every new recipe I try is from your site (that’s not completely true, but close), and how I, um, sometimes refer to the source casually as though we were buddies, as in, “This recipe? it’s from Mel.” But really, I am so grateful for this blog and the way it has enriched my dinner making experience and blessed my family. I hope you have a wonderful birthday and get to enjoy every bite of this torte.
This dessert is AMAZING. It took a little while to make and some patience but sooooo worth it. I can’t wait to make it again. I may just make it just because.
I loved this! I love all your recipes. I was browsing your recipes trying to find something chocolate for my daughter to make as a thanksgiving dessert (she volunteered), and I thought of this, but I couldn’t find it in cakes or pies. What category is it filed under? Thanks!
Hi Laura – it’s filed under the cakes category.
I don’t know how I missed it. Thanks!
Jody, that is what I did for Christmas and it worked out great. Delicious dessert!!!!!!
I am not sure you will get this comment/question since this is an older post, but thought i’d try anyways.
If I am making this for Easter, can i make it Saturday evening, refrigerate overnight, and then do the whipped cream topping/raspberries right before I go over to the in-laws on Sunday afternoon?
Hi Jody, yes, you can definitely make the cake and mousse part a day or two beforehand. Just keep tightly covered in the refrigerator until you top with the cream and fruit.
Made this for Christmas Dinner . . . oh my goodness! So delicious! Hardly any leftovers and I will definately be making it again. Somewhat labor intensive but nice that you can make it in different steps. To all you thinking about making it do it! Don’t be intimidated by the multiple layers. Thank you for such an amazing blog. BTW, I used a 9 inch pan and it turned out just fine.
I’ve made this twice– both versions. It is incredibly good (wouldn’t it violate some law of thermodynamics if a cake that called for 1lb of chocolate wasn’t good?). I think I prefer the whipped cream mousse version, which I made last night because I had a pregnant guest. It’s a little bit faster and I like the texture slightly better (still, both versions are beyond delicious). This is a definite crowd pleaser.
Ooooh MY. This cake was the-best-cake-that-was-ever-eaten. EVER. Made yesterday for husbands b-day and entire family groaned and insisted on it for all upcoming birthdays of all times. AMAZING. THANK YOU!
Nancy – I think a 9-inch will work just fine. You’ll get slightly deeper layers but just like Jnl2211 said – it should work with no problems.
I used a 9 inch with no problems.
I want to make this for my husband’s birthday tomorrow but my springform pan is 9″ in diameter. Will that work or do I need to make adjustments? Or go buy a 10″ one? Thanks for your help!
Happy Holidays Mel! I just wanted to pop in and say I made this for Christmas. I also used the base cake and topped it with a peanut butter cream cheese mousse covered in chocolate ganache and it was heavenly! I hope you had a wonderful day!
Yes, yes, and yes!! I was scanning through the comments and saw a few people mention that they couldn’t wait for the next special occasion to make this and I was thinking of how bad I am…I always make stuff like this just because…and then I wonder why I’m not losing weight while breastfeeding twins!! This recipe is absolutely DIVINE! I wanted to eat the whole bowl of mousse by itself! Thanks for a wonderful recipe.
So to follow up on my panicky comment: I popped that baby into the freezer for maybe twenty minutes, and then the fridge for about two hours, and it set perfectly. The texture was fabulous too, so I think all is well that ended well! It was astronomically delish! Thanks!
Hello Mel,
So like an idiot I didn’t completely read through the instructions before I started, and I’m just not smart enough to realize that mousse would take hours to chill. SO. The cake is currently in the oven with about 10 minutes, and I’ve got family coming over for my little birthday party in about an hour. We won’t be ready for dessert for another three hours or so, but this sucker will probably only get like two hours chilling. What do you think? Should I pop it in the freezer? I’m worried about it actually freezing, and ruining the texture…. Hopefully it will be good however chilled, but I wish I had known ahead of time that this is a cake you need to make ahead…:)
Miriam – so…did it work out? I think freezing for a little wouldn’t hurt it but I hope the 2 hours of chilling time worked out ok. I usually try to make a note on the recipes what portions need to be made ahead of time. Sorry I missed the boat on this one. Happy birthday!
What a truly joy of a writing
Hi Mel,
I just found your magnificent looking cake from a Google search of chocolate mousse tortes. I want to make this cake for someone’s birthday, but I would have to take it to a restaurant with me and it might have to sit unrefrigerated for ~2-3 hours. Do you think everything will hold up for that long? Or could I maybe freeze the cake and then take it with me to the restaurant? If that’s possible, do you have an idea of how many hours it would take to defrost?
Thanks!
Lillian – it makes me a tad nervous to think of this cake unrefrigerated for that long. The mousse is rather delicate and I can see that it might have the tendency to get a little melty or ultra-soft at room temperature for too long (although a cool room temperature might be ok). I’ve never frozen it so I don’t know how the texture of the mousse would hold up to that. If you had to choose between the two, I’d try to keep it at cool room temp for a couple of hours over freezing it. Good luck!
Question, if I don’t have a springform pan (sad, I know!) should I use a 9×13 pan on this? Thanks!
Mel, thanks for the help. As always, this recipe was a hit!!
Readers – don’t be intimidated by the directions; they may seem a bit daunting, but trust me, just take it a step at a time and it will be easy!
Just to clarify, because I want to make sure, when you say semi sweet chocolate, do you mean like chocolate chips, or baking chocolate (like the ones the Pioneer Woman uses to make her French Silk pie) ? Thanks!
Laura – I always use the baking chocolate that comes in bars because chocolate chips don’t melt the same way (due to the different amounts of cocoa butter).
I don’t have a working candy thermometer so I just went with your 6 minute suggestion when I made this. My custard did break at about 3 minutes. I just finished it and stuck it in the fridge so I haven’t tried the final product yet. The mousse tastes amazing but is pretty grainy right now. Do you think I overcooked the egg yolk mixture?
Natalie – hmmm, I’m not sure about the graininess. It might have been overcooked but it’s hard to know. Did it end up tasting ok? Graininess or clumpiness could be due to overcooking the egg yolk mixture but it’s hard to know exactly.
Hey, Mel….what do you think the difference would be if you used milk chocolate instead of bittersweet? I love milk chocolate, and I’d like to try it out in this recipe, but I’m hesitant because I don’t want it to be too sweet or overpowering.
Jenn – the only concern I have using milk chocolate in this recipe is that because different types of chocolate have different melting properties (based on how much cocoa butter/sugar are in them), using it might mess with the texture of the dessert. However, in my world, anything is worth a try. If you did use it, I’d probably decrease the sugar by a little to counteract the sweetness.
Made this for V-day and it was perfect and pretty easy to put together I thought. I love it when you don’t have to work too very hard for great results. Thanks!
Two words…..FREAKING FANTASTIC!!! Thank you again for making me look like a rockstar!
Ha, Jenn! You are funny – glad you loved it!
Oh my. I made this amazing, addicting, heavenly dessert, and all I can say is–Melanie, you are an evil woman. 😉
Kara – so sorry! You can blame me for sure, but at least it tasted good, right?
oh, and I made one with strawberries too…also delish!
Emily – love the idea of strawberries with this dessert. Glad you liked it!
This was easier that it looks…..and sooooo good! Thanks, a new favorite!
I made this for Father’s day.
I thought the overall recipe looked kind of complicated, but it really wasn’t. The oven was only on for 30 minutes, which is good. (I hate to bake in the summer.) It turned out great!! I thought the sweetness was just right using half semisweet and half bittersweet chocolate. Definitely as good as any restaurant dessert! Also, I cheated and used whipped cream out of a can. Saved a step.
Sara – I’m so glad you liked this recipe since it is such a personal favorite of mine. I’m glad it made for a great Father’s Day dessert!
Now I know how to use up the huge clamshell of raspberries I just bought at Costco! And I’m definitely requesting this as my birthday cake next week! Thanks for the recipe 🙂
kadie – I apologize! I hate it when I try a recipe and it isn’t accurate. I’ve edited the recipe, but here’s the low-down:
-the extra 1 1/2 teaspoons sugar was in the original recipe and was used to sprinkle over the entire torte (if using the red currant jelly, which I omitted), so I’ve taken that 1 1/2 teaspoons out of the recipe like I should have done in the first place
-the 1 cup cream is actually divided, 1/4 cup is used for the mousse and the other 3/4 cup is in the topping – I had it listed incorrectly in the recipe.
All is fixed now. Thanks for the heads up!
Wow! Wonderful recipe! As soon as I saw it I knew I had to make it! And I did. A few questions though…For the mousse, I noticed that the recipe calls for 1 cup whipping cream and then the directions say 1/4 mixed into the egg yolks with vanilla. Where does the rest of the cream go or is that a typo? Also in the mousse it calls for 1/2 cup plus 1 1/2 t sugar. Where does the other 1 1/2 t go? I just guessed and it turned out GREAT! But I would love to know how you did it. My husband said it was a dessert he thought you could find at a very expensive restaurant!
Oh my – I think I’ve died and gone to chocolate heaven!!!
Wow…what a stunning dessert! I always order chocolate mousse cake when dining out, but now I can make a better version at home! If you love it, I know I will! Thanks for sharing your talent and love of cooking with us, Melanie! 🙂
boy-o. do i like the looks of this! ethereal indeed, and completely irresistible. if your fame and fortune arrive soon, i can say i knew you when. 🙂
Anything that has the words double chocolate gets printed and saved…I love this recipe.
This looks AMAZING, Mel!! I’m bookmarking this.
Mmmmm! This looks divine! Can’t wait to try it…though it may have to weight until this baby weight is gone… 🙂
I’m with Dessert for Two. Thanks for posting such a well tested recipe. I’ll feel comfortable making this for the first time for company. I’m also curious about Anne’s questions regarding freezing and preparing ahead. I’m excited about this one!
Ok, first I’m going to need to finish the lemon cheesecake I just made thanks to you, and THEN I’ll make this. And I’m pretty sure I’ll die of happiness. And not be able to fit in my jeans.
Yum! Looks like a beautiful chocolate cloud with raspberries on top.
DROOOOOOOOOOOL!
So is this super amazing dessert super rich (like a truffle) ? and super sweet too?
Katherine – this dessert is not overly sweet because it is made with bittersweet or semisweet chocolate. I mean, don’t get me wrong, it is definitely sweet, but not so sweet that you are gagging. Now as for rich, yes it is rich – but the lightness of the chocolate mousse layer helps offset the dark, decadent richness.
Melanie, you sold this recipe so well that I am up at 3 am finishing making it for a chocolate-making class I am hosting tomorrow. I have a few questions for future reference. Have you ever made this ahead by a few days? How does the taste/texture hold up if frozen? Can I put the mousse layer on top of the torte layer while the torte is still warm, or is cooling it fully the best bet? Thanks! I am very excited to sample it tomorrow!!
Anne – I’m excited to find out what you think about this recipe. As for your questions (Kelly had the same ones), I’ve only ever made this up to one day in advance. I would definitely not recommend freezing it. I think the mousse layer would break apart and the texture would be a little weird. However, I think you could make the base cake layer in advance and freeze that. I would thaw to room temperature before adding the mousse and whipped cream. Definitely cool the torte layer completely before adding the mousse. In fact, I need to go back and specifically state that. If the torte layer is warm at all, the mousse will melt and turn very runny. I hope that helps!
Wow. Thanks for posting such a well-tested recipe! I will bookmark this for the next time I have to make something very special!
Oh. Wow.
Looks like heaven on a plate!
This looks right up my alley! Beautiful.
So festive and delicious. I would definitely make that for a super special occasion.
