Caramel Oat Chocolate Chunk Shortbread Bars
These easy and delectable caramel oat chocolate chunk (or chocolate chip!) shortbread bars are simple and perfect for any sweet craving!
I love bar desserts. Love ’em.
They are my go-to Sunday sweet when I haven’t thought far enough ahead to make a triple layer chiffon cake with vanilla bean pastry cream filling and edible flowers for garnish.
So…basically, they are my go-to Sunday dessert 99.9% of the time.
A couple weeks ago, I wanted a quick Sunday treat but I was craving something new. Something different.
Something so crazy delicious, my family would ooh and aah and erect a monument in the backyard dedicated to Their Loving Mother Who Makes the Best Bar Desserts Ever.
All I can say is: mission accomplished.
These caramelly, oaty chocolate chunk shortbread bars are amazing!
And there’s no real surprises or secret ingredients. They are exactly like they sound.
A buttery shortbread base is prebaked and then topped with a quick and simple browned butter, quick-caramel mixture studded with chocolate chunks (or chips), oats, coconut (but only if you wish!), and toffee bits and then baked again.
The textures! The flavors! I mean, you can put just about anything on top of a shortbread crust this delicious, and I’d probably eat it.
But when it’s an ooey gooey mixture with chocolate (of course) and a hearty touch of oatmeal and toffee, well, I’m going to be all over that.
What really got my family constructing that best-mom-ever monument ASAP was when we scooped the delectable shortbread bars right out of the pan, still very warm, and topped them with a scoop of vanilla ice cream and a drizzle of caramel sauce.
Oh my heavens. Deliciousness that knows no ends.
My kids will never know this divine variation resulted because I didn’t plan ahead far enough to let the bars cool, of course, but what they don’t know can’t hurt them, right?
Make these and I guarantee you’ll get your own life-size monument dedicated to your awesomeness…or your money back! Er, or something like that.

Caramel Oat Chocolate Chunk Shortbread Bars
Ingredients
Shortbread Crust:
- 1 ⅔ cups (237 g) all-purpose flour
- ¼ teaspoon salt
- ⅓ cup (71 g) granulated sugar
- 14 tablespoons (199 g) salted butter, cold, cut into tablespoon-size pieces
Filling:
- ½ cup (113 g) salted butter
- ½ cup (106 g) granulated sugar
- ¾ cup (159 g) light or dark brown sugar (I prefer dark brown in this recipe)
- ¼ teaspoon salt
- 3 large eggs
- 1 teaspoon vanilla extract
- 1 cup (100 g) old-fashioned rolled oats
- ½ cup (43 g) shredded coconut, sweetened or unsweetened (optional)
- ½ cup (85 g) toffee bits
- 1 ½ cups (255 g) white, milk, semisweet or bittersweet chocolate chunks or chocolate chips (can use a combination!)
Instructions
- Preheat the oven to 350 degrees F. Line a 9X13-inch pan (I prefer metal/aluminum baking pans for recipes like this) with foil and grease with nonstick cooking spray. The foil is optional but helps with pulling out the bars and with clean up.
- In the bowl of a food processor (read on for alternate method!), add the flour, salt and sugar. Pulse a few times to combine. Scatter the butter across the mixture and process for another 30-45 seconds until the dough clumps together in several large pieces (it should stick together if you press a handful together). Alternately, you can combine the flour, salt and sugar in a large bowl and cut in the butter using a pastry blender, two forks, a couple knives, etc. Continue cutting in the butter and mixing the ingredients until you can press large clumps together in your hands (the butter will be in very small pieces).
- Press the shortbread crust into an even layer in the bottom of the prepared pan. Bake for 15-20 minutes until the sides are just barely golden. Watch closely so the crust doesn't burn. It's better to take it out early rather than let it bake too long.
- While the crust bakes, prepare the filling by melting the butter in a medium saucepan over medium heat. Cook the butter, stirring often, until it melts completely and little brown bits appear on the bottom of the pan (you are browning butter! Here's a quick tutorial if you want a visual). This will take a couple minutes, but watch closely, or else it can go from brown butter to burned butter very quickly!
- Off the heat, stir in the granulated sugar, brown sugar and salt. The mixture will be thick. Let it cool for a few minutes.
- Whisk in the eggs and vanilla until the mixture is well-combined.
- Stir in the oats, coconut (if using), toffee bits and chocolate chips. Spread the mixture evenly over the shortbread crust.
- Bake for 20 minutes until the bars are set around the edges and the middle isn't super jiggly (a little jiggle is ok, but bake them a few minutes longer if the middle of the bars still looks really liquidy). If you aren't sure if the bars are done, err on the side of taking them out without overbaking, even if they still seem a little gooey in the center. They'll set up as they cool.
- These bars are delicious served warm (scoop them right out of the pan and don't stress about getting clean cuts) with ice cream OR you can let the bars cool completely and cut into squares and serve.

These were so good. My husband has named them “chonky bars” because the original name is too long for him to remember when he requests these 😉
Haha, this made me giggle. I think I might start calling them that, too.
Hi Mel,
Can you make them in advance? Freeze them? How quickly do they dry out?
Btw I love every recipe of yours!
Thank you!
Yes, they can be baked, cooled, cut and frozen in ziploc bags or a covered container for a couple of months.
I made these bar cookies on Sunday for my family. They are so rich! I am curious if the recipe could be modified to reduce chocolate chips and/or toffee bits? So it wouldn’t be so sweet? Maybe substitute chopped almonds and/or pecans in place of some of the chocolate chips.
Oh my word! I will erect a statue for you, and I’ve never met you. I haven’t even made these yet, but I can tell! Statue-esque. I’m popping on here to suggest maybe Cinnamon ice cream on top? That surely can not go wrong. (my go-to cinny ice cream is from browneyedbaker.com)- I will add this to my growing arsenal of your recipes!
Oh my! Just came out of the oven and giving a 5*. Hard to eat just one. Will definitely make again.
Thanks, Nancy!
Delicious! Devoured by the youth at youth group tonight!
Do you have a search bar? I hate looking through everything just to find a recipe.
Yes, it’s at the very top of the web page.
Where do u purchase toffee bits?
I find them near the chocolate chips at the grocery store.
BEYOND YUMMY! This bar cookie is so good we couldn’t leave them alone. Make them for your family or to take to any get together and be ready for the rave reviews and request for the recipe…
I made these last night. They were delicious while they were warm, and they are still gooey and yummy today, the morning after. I’d say they taste like a cross between a butter tart and a magic cookie bar/hello dolly. I opted to add about a scant 1/4 cup more oats to mine and the result is great. Thanks for another tasty recipe!
These are fantastic! Everyone has been raving about them. I kept them in the fridge and they taste great chilled.
I loved these! Unfortunately, I didn’t have any toffee bits on hand, but they were still to die for. I thought they were even more tasty the day or two after I made them. The chocolate was amazing, but what do u think of having a fruit filling over top The shortbread crust instead?
I think that would be delicious, Lauren!!
Just had to check back in to say that these r the best treats ever! I kept them in a container in the fridge & we all kept going back each day for more. (Recipe makes a lot!) My husband (who doesn’t eat chocolate-oops!) kept eating these bars, saying how awesome they were. He ate the last 2 last night, & I’m honestly thinking I need to make more ASAP. These r a HUGE win. (I used a combo of semi sweet bitter sweet & mini choc chips)
There’s something about them that’s hard to stop eating – I agree! Glad you loved them!
I made the bars today. They do not look like yours at all. Mine do not have the nice layer of oatmeal on the top. I added my oatmeal to the filling as the directions said. Did I do something wrong?
This happened to me, too! Still taste delish but look blah.
Hmmm…I’m not sure why that would happen. So the oatmeal is more incorporated like cookie dough in your bars? How thick or thin was your oatmeal/egg/sugar mixture when you layered it on top of the shortbread?
It was definitively more thin than thick. They still tasted great, but I just wondered where I went wrong.
Make sure to use old fashioned rolled oats. The kind you cook 5 minutes. 1 minute oats and instant oats not so muc
I had this same problem. Is it actually three layers? I was hoping for the oatmeal on top, but it was all covered in chocolate, kind of like no-bake cookies.
I’ve made these three times now, the first two times I had the same problem. I solved it by letting the sugar/butter/egg mixture cool almost completely while I mix chocolate chips/oats/toffee/coconut in a separate bowl. Then I add it to the egg mixture and stir it til just combined. This way the chocolate chips don’t melt and it ends up looking like the picture – caramel with oats and chocolate chips mixed in, instead of just a brown mixture.
These bars are so delicious! I had to give them away to keep me from eating the whole pan…..I have no self-control. Thanks for another amazing recipe, Mel!
Amen to that, Mel! I’ve had to start getting these out of the house ASAP when I make them. Glad you loved them!
These are amazing! They remind me of Hello Dolly’s (some people call them magic bars) but I love the way the caramel stays a little bit gooey. I think I’m going to throw is some chopped pecans next time, either to the crust or on top.
These are SO good! I mean, you can’t go wrong with browned butter, toffee, and chocolate! I’ll be making these again and again! They’re so good and a little different from the usual brownies and chocolate chip bars!
So glad you loved them, Becky!
So what is the difference using a metal/aluminum pan vs a glass pan? I only have glass baking dishes, but if you say I need a aluminum one, far be it from me to question the cooking knowledge of Mel! I just need a reason when my husband asks me why I’m buying more kitchen stuff!
That’s a great question – glass pans don’t conduct heat the same way metal pans do, so if a recipe is tested using a metal pan, it may not turn out the same using a glass pan (sometimes for bars and brownies, the edges will cook faster in a glass pan while the middle stays raw). I suggest if using a glass pan to turn the heat down by 25 degrees (but I would definitely support you getting yourself a metal 9X13 pan, too!) 🙂
Delicious!! My family LOVED it! Do you use salted or unsalted butter?
I always use salted butter.
Good to know! Thanks!
I have never browned butter before, because I didn’t see the reason for the extra time, and it’s not like I was skipping ingredients. Today I didn’t skip that step. Oh my goodness! What a difference browning the butter makes! I may or may not be at risk for browning butter, adding a little sugar, needing it right out of the pan. Yum! Thanks for the tutorial.
Haha, I TOTALLY know what you mean! Takes it to a whole new level. 🙂
I realize there aren’t many of us in the world who love chocolate in tiny amounts,
but do you think subbing raisins for the chocolate would work?
Yes, absolutely!
I need a new bar recipe in my life and these look SO good!
The first thought that came to mind when I saw these was, “those look amazing!” Then I read the title and knew that they indeed would be amazing! Now to make them and enjoy their awesomeness!
Are the toffee bits the same thing as the heath bar bits they sell in the chocolate chip section or are these something else entirely?
These look divine!
Yes! Should be the same thing. There’s often chocolate-covered and regular toffee bits. I use the ones that aren’t covered in chocolate. But either would probably work!
I found them today at Walmart. They’re called “Bits O’Brickle” for anyone wondering ☺️ Looking forward to making them this weekend!
You had me at the title! Making these ASAP. Thanks Mel!
I saw these in Deb’s cookbook and they did look amazing. Now after your post I think I must make them. I love those Trader Joe’s chocolate chunks you recommended–so good–we love them right out of the bag!
Same here!
It’s taking every ounce of strength I have to do the dishes instead of making these RIGHT THIS INSTANT!!
Holy moly, these look amazing.
Darn it! I was looking for something like this earlier today, but I had to get it made ASAP. Now look what I missed out on. I’m going to have to try these for sure. They look amazing!
I’m sorry! I meant to have this all posted early this morning…but…life! 🙂
Could these be made without the toffee bits? I have all of the other ingredients. 🙂
Totally! I mean, I might cry a little at the loss of deliciousness, but they’ll still be super tasty. 🙂
Booyah, making these tonight!
So I did make these and they were super delicious! My dinner guests obsessed over them. Thanks for a great recipe!
So happy to hear that, Carmen!!
