Nutella Butterscotch Crumble Bars

Once upon a time there were two boys, brothers no less, who had the day off school. When the “littles” in their family went down for an afternoon nap, they overstated the fact that they were bored, bored, bored. So their brilliant Fairy Godmother (ok, their mom) suggested they could either a) clean the toilets or b) make some delicious bars her equally brilliant Aunt* had just sent the recipe for.

The boys made a brilliant decision of their own and chose the kitchen job. And they performed their task all by themselves.

Nutella Butterscotch Crumble Bars

The boys had the time of their lives and changed their official bios to state they would be chefs when they grow up instead of firemen. Of course, the happy ending fell a bit short when their mom informed them that just because they made the bars from start-to-finish didn’t mean they could eat the bars from start-to-finish.

Alas, all is well in the end since the two brothers have been enjoying one of their famous creations in their school lunch every day and are still bragging to their friends about the “day they made those awesome nutella-scotchie-mallow bars without any help.”

*Since my awesome Aunt Marilyn has her own recipe category and all, I thought I’d show you what she looks like in real life, pictured below with her daughter and friend. Aren’t they the cutest? Their family just relocated from Washington D.C. to Boise (Eagle), Idaho. Methinks I need to plan a trip out there and fast (all in the name of recipe development, of course)! Thanks for all the great recipes, Aunt Marilyn!

Nutella Butterscotch Crumble Bars

Nutella Butterscotch Crumble Bars


  • 2 cups granulated sugar
  • 3 cups all-purpose flour
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1 cup (2 sticks) butter, softened to cool room temperature
  • 2 large eggs
  • Filling:
  • 3/4 cup Nutella (chocolate hazelnut spread)
  • 1 1/2 cups mini marshmallows
  • 3/4 cup butterscotch chips


  1. Preheat the oven to 350 degrees F. Line a 9X13-inch pan with foil (leaving an overhang on each long side for easy removal of the bars after they have cooled) and lightly coat the foil with cooking spray. Set aside.
  2. In a large bowl, mix together the sugar, flour, salt and baking powder. Cut the butter into tablespoon-size pieces and add to the dry ingredients. Cut in the butter with a pastry blender or two knives until the mixture is crumbly. Add the eggs and mix with your hands until the eggs are incorporated and the mixture forms a cohesive mass (it will still be slightly crumbly but should come together). Set aside 2 cups of the mixture. Press the remaining dough into the prepared pan and bake for 11-12 minutes until the dough starts to look slightly set and may be very lightly golden around the edges. Don't overbake at this point since it will be baked again.
  3. While the crust is still hot, spoon dollops of Nutella over the top and smooth into an even layer with an offset spatula or rubber spatula. Sprinkle marshmallows on top. Sprinkle on the butterscotch chips. Crumble the reserved dough over the top and bake 15-18 minutes, until the crust is lightly browned and the marshmallows are puffy and golden. Cool the bars in the pan. Use the foil overhangs to remove the bars and cut into pieces to serve.

    I made these yesterday and they were SO good! A repeat for sure!

  2. Connie L. Rohal says:

    Love this websit!!

    I’m surprised there aren’t more comments. These were awesome!! The only change I made was that I halved the amount of butterscotch chips and substituted semi-sweet for the other half (just because one of the other comments mentioned they couldn’t taste the Nutella). I also liked them even more after they chilled (and they looked prettier too). I took these to a baby blessing and they were a big hit. Thanks for all the great recipes!

  4. Stacie A. says:

    These were amazing!!! I get requests to make them all the time. 🙂

  5. Felicia says:

    These are great! My family loved them and so did the neighbors I shared them with. Thanks so much!

  6. Mel says:

    Georgia – I’ve never made them that way but it’s worth a try.

  7. Georgia says:

    Do you think I could make these without the marshmallows? Maybe increase the nutella? Thanks so much!

  8. Melissa P. says:

    I just realized that your Aunt Marilyn is one of our dear family friends! I love her! Give her a big squeeze for me!

  9. Angie says:

    I just made these this weekend. People loved them. However, I didn’t taste the nutella…so I made another batch (first batch was gone) and omitted the nutella. Still a hit! Probably because of the 2 sticks of butter and 2 cups of sugar!

  10. DEE says:

    Well……helloooooooo “Aunt” Marilyn!

    I am SO jealous of Aunt Marilyn… we have been trying to get to Eagle, ID for about 5 years now… We LOVE it there!!! Here’s hoping it will happen soon! Can’t wait to try this one… your recipes never fail!!!

  14. Jen M says:

    Why must you tempt me like this? Nutella is such a heavenly food that anything made with it makes me want it NOW! I’m pinning this to try later. Oh, and BTW I haven’t been able to use your search bar for the past few days. It always gives me an error.

  15. Molly says:

    What a small world! I’m in Eagle too!! Love all your recipes, Mel 🙂

  16. Liann says:

    Yes, come on out to Eagle. Looks like that photo was taken at our Saturday market. We would love to have you. Keep the great recipes coming. 🙂

  17. These look wonderful! I have been quietly enjoying your blog for some time now, and as a fellow Minnesotan, I love knowing that you are up north! Happy cooking…and eating! Thanks for sharing such yummy things!

  18. Sarah A says:

    These are going to be my Cookie Swap cookie…even though they are bars… otherwise I would eat the entire pan!

  19. Elaine says:

    I love your Aunt Marilyn’s recipes.. yours too! I live in Meridian, Idaho, which kind of runs into Eagle. She will love it here!

  20. Jessica says:

    You had me at Nutella! And I will gladly volunteer to go visit your Aunt Marilyn (I love so many of her recipes that she shares with you!) I’m headed to Boise today in fact. So if she needs a taste tester or someone to eat the leftovers out of her fridge I am game! LOL!

  21. Melanie Miller says:

    Fun presentation this morning, Mel! Good job, boys, I am impressed with your talents. Shout out for Boise, we live close to there! Yes, please come west!

  22. Tami says:

    I love Aunt Marilyn. We have stayed with her many times and have been fed so many wonderful meals. I am truly in awe of this lady. She always got up really early (early morning seminary kind of early) to make sure her 7 kids had a hot cooked breakfast before school. She also is an amazing seamstress, a talented picture framer, and a wonderful piano player. She is delightful to visit with, takes an interest in others and is just really kind. I know Mel already knows this but I thought your readers would want to hear more bragging about Aunt Marilyn.

  23. Ohmygosh YUM! I am a sucker for Nutella, but it’s been on the back burner with my current pumpkin craze. Thanks for reminding me of this wonderful ingredient. I’ll have to bring it back into my life with these bars. 🙂 Great recipe!

  24. Amanda E says:

    You’ve got to be kidding! Can’t wait to make these. The whole family will love them I know. Especially hubby, who’s a Nutella freak and in Afg. Hope they make there to him, for we may eat them all!

  25. The name itself lures people to this post. Your boys are just the cutest! And kudos for all those aunt marilyn´s recipes!

  26. StephenC says:

    Very few things of this sort tempt me at all. However, temptation is staring me in the face and audacity is pushing me toward a couple of modifications to satisfy local appetites (mine). I might just use a store-bought pie dough (I like it and it’s got less calories I think). Nutella is right up there in the top ten things I never learned about until I was nearly 40. Marshmallows are the devil’s work (lol). I’d like to sub in some vanilla pudding and make the topping from caramels (in care of “mels”). If I ever get around to this you will be the first to know. Bookmarking as we speak.

    What a sweet story! Your boys are adorable, Mel! The nutella bars look delicious. Yeah for Aunt Marilyn! 🙂
