Today I made you Nutella Crumble Cake Bars: an easy 4 ingredient recipe that starts with cake mix and is filled with gooey chocolate!

Nutella Crumble Cake Bars - this easy cake mix recipe is a bar cookie filled with NUTELLA!! Is there anything better?


Are you ready for some easy cake bars? I sure am.

Tomorrow is my mom’s birthday (happy birthday mom!) and I always look forward to making her birthday treats. My mom is the best guinea pig; she’ll eat any dessert I make her! Over the years I’ve made her Turtle Brownies and a Turtle Cake Roll, and last year I made a Snickers Poke Cake. Do you see any themes running through those? My mom LOVES chocolate. She’s a certified chocoholic.

The apple doesn’t fall far from the tree.

This year, instead of an elaborate cake or single flavor of cookie or brownie, I decided to make my mom a checkerboard of dessert. I put together a pan, checkerboard style, of some of my favorite brownies and bars: Oreo Truffle Brownies, Nutter Butter Truffle Brownies, Oatmeal Scotchie Cheesecake Bars, and these Nutella Crumb Cake Bars.

Favorite. Birthday Dessert. Yet.

Easy Nutella Crumble Cake Bars Recipe

These Nutella Crumble Cake Bars could not be easier to make. They only have 4 ingredients: cake mix, butter, egg, and Nutella. That’s it!

The Nutella stays gooey and gives the bars a super rich chocolatey taste, but they still taste like birthday cake too. Do you ever crave the “traditional” birthday cake? You know, yellow cake with chocolate frosting? These bars are like that, but in cookie bar form. #priceless

Plus, these Nutella Crumble Cake Bars come together in about 15 minutes. You can’t get much better than that!

How to Make Nutella Crumble Cake Bars

Soft, crunchy, chewy, and chocolatey. Those are the hallmarks of every good dessert, if you ask me!

A few recipe notes:

  • You can use any brand yellow cake mix.
  • You don’t have to use Nutella. Use any brand chocolate hazelnut spread or any chocolate spread!
  • When you’re mixing these, the dough comes together and is very stiff. If you’re using a hand mixer it might take awhile to get to that point.

  1. These look amazing, can’t wait to try them! Love Nutella and anything with hazelnut! I actually found a spread that is similar to nutella but without the chocolate, just straight up hazelnut, it’s delicious. No idea what its comparable to though, I’ve only found Shoprite brand lol. I’ve been wanting to bake with it but am so afraid that it’ll not hold up the same as Nutella, or peanut butter, and will melt into whatever I make rather ththaththan being a distinct layer and I love my layered desserts! Lol. Have u ever heard of this spread? And any ideas as to what would happen when baking with it? Would love to use it in these!
