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!

  2. 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!
