Ingredients

Instructions

  • In a large mixing bowl, add cake mix powder, pudding mix eggs, oil and mix until just combined. The batter will be thick.
  • Stir in all the chocolate chips and m&m candies. 
  • Spread this mixture in a greased and floured square cake pan (Dimensions: 9x9). 
  • Swirl warm Nutella on top of this batter with a butter knife.
  • Bake at 350 degrees F for 20 minutes if you like your bars soft OR bake them for about 30 minutes if you like your bars firm. 
  • Allow it too cool to room temperature. Cut slices and enjoy!

Notes

  • All ingredients must be at room temperature.
  • Don't over-bake because that will make these bars dry. 
  • Read additional tips and variations above. 
  • Leftovers can be stored in a sealed container in the fridge for up to 5 days. 
  • Heat Nutella for a few seconds to make it easier to swirl on top of the batter.
  • Try other add-ins like peanut butter, shredded coconut, chopped nuts, extracts, pretzels e.t.c.
  • Use Pillsbury cake mix boxes because they are 15.25 oz. The other brands have gotten smaller and won't work well.
