Tips for Success

  • For this recipe, yellow cake mix is the preferred mix because it gives the Funfetti blondies the perfect texture. A white cake mix or funfetti cake mix won’t come out the same. I’ve tried and yellow is the way to go!
  • The batter will be thicker than a cake mix and slightly stiff so it should be easy to spread with a spatula.
  • You can add any color of sprinkles that you like- give your Funfetti Cake Mix Blondies some Christmas or Valentine’s Day flair using seasonal colors or use your favorite teams’ colors. Whatever you choose, have fun with sprinkles!

What is the difference between a brownie and a blondie?

The simple answer to this question is chocolate! Brownies are typically made with cocoa powder and sometimes chocolate chips, whereas blondies have no chocolate but have a delicious vanilla taste instead. Also, blondies are a more dense dessert and that is what makes it different from a fluffy, airy cake.

Can I add chocolate chips to the Funfetti Cake Mix Blondies?

Heck yes, you can! Many people choose to use white chocolate chips in Funfetti blondies but milk chocolate chips also work well in this recipe, it just depends on what you like. To add chocolate chips to this batter use 1/2 cup of any size chocolate chips.

Notes

I do NOT recommend using funfetti or white cake mix for this recipe, only yellow.
