Ingredients in Cake Mix Bars

  • Cake mix – I used yellow cake mix but you really could use any flavor.
  • Butter – unsalted, softened butter
  • Nutella – or other chocolate spread

Be sure to see the recipe card below for full ingredients & instructions!

How to Make Nutella Cake Bars

  • Preheat oven: Using aluminum foil and cooking spray, line, and grease a 9×9 pan. Preheat your oven to 350°F.
  • Make the dough: In a mixing bowl, beat together cake mix, butter, and egg with a hand or stand mixer. Continue beating until the dough becomes stiff. 
  • Assemble: Once the dough is finished, press approximately ½ to ⅔ of your dough into the bottom of your 9×9 pan. This will create the bottom layer of your cake bars! Spread Nutella evenly over this bottom layer, just shy of the edges by about ¼ inch. Use the remaining dough to create the top layer of your bars, covering the edges. 
  • Bake: Bake for 20 to 25 minutes. You’ll know your bars are done when the edges begin to brown. Allow the bars to cool completely before removing or slicing them. 

Expert Tips

  • If you’re using a hand mixer to beat together the dough, it will take you longer to achieve the firm consistency you’ll need than it would with a stand mixer. 
  • Nutella is my favorite, but feel free to use any chocolate hazelnut spread you like!

  1. Just pulled these out of the oven (first time making them) and my kitchen smells amazing! The most difficult part of this for me is “waiting until cooled completely” before taking out and cutting. If I did not know the pan would melt the plastic shelves in my freeze or think that the integrity of the bars would suffer going directly from oven to freezer, I would totally do that to get these in my face faster!

  2. I made this to take to a party, it was a success and it’s a tough group. The plate was empty! I’ll definitely use this recipe again, thank you!

  3. I don’t have a sweet tooth but these Nutella Crumble Cake Bars look too great, thanks Dorothy for sharing

  4. Girl, you had me at Nutella… and then again when I saw there were just FOUR ingredients in this yummy recipe!  

  5. I made the Nutella Crumble recipe tonight in preparation for a friend’s birthday. I gave my parents samples once the bars cooled and got rave reviews (they asked for seconds and thirds). I was a tad hesitant about trying the recipe because I’ve never baked using Nutella before, but it was an instant success. hey ended up comin gout fluffier and altogether better than I was anticipating. Preparing the bars was super quick and easy too — perfect for a busy night that begs for baking something. The cooking time took a bit longer in my oven (closer to forty minutes than 20-25), but that could be because I have an older oven. I’m excited for my friends to try these tomorrow. Thank you for he recipe!

  6. girl, these bars are flippin genius! I do crave the traditional birthday cake but have zero desire to make a layer cake!! But, let me tell you, anything with Nutella that comes together in 15 minutes is going to be a problem! Hope you are doing well! xoxo

  7. I get my sweet tooth from my dad. .  my mom doesn’t like sweets. .  I don’t even understand. .  😛 LOVE these cake bars!!! and only 4 ingredient?! LOVE!!!
