Ingredients

FOR THE BLONDIES:
  • 1 cup light brown sugar packed
  • ½ cup butter melted, unsalted
  • 1 egg large
  • 1 teaspoon vanilla extract
  • ¼ teaspoon kosher salt
  • ¾ cup all-purpose flour
  • ½ cup yellow cake mix dry
  • ¼ cup Sprinkles
FOR THE FROSTING:
  • ¼ cup butter softened, unsalted
  • 2 Tablespoons milk
  • 2 cups powdered sugar
  • 2 Tablespoons yellow cake mix dry
  • 2 Tablespoons Sprinkles

Instructions

    Cup of Yum
  1. Preheat oven to 350°F. Line an 8-inch square baking dish with parchment paper. Set aside.
  2. In a large mixing bowl, combine brown sugar with melted butter. Add in egg, vanilla and salt. Mix until blended. Add in flour and cake mix, stirring JUST until combined. Fold in sprinkles.
  3. Pour batter into prepared baking dish. Bake for 22-25 minutes. Remove from oven and cool completely.
  4. While blondies are cooling, prepare the frosting. Beat butter with milk, powdered sugar, and yellow cake mix. Once smooth, spread over cooled blondies. Add sprinkles. (I used a combination of fun sprinkles and rainbow chips). ENJOY!

Notes

  • Do not over mix. I prefer to mix the batter by hand for this recipe, especially after adding the dry ingredients. Over blending can make blondies tough.
  • Line your pan with parchment paper. This makes it so much easier to remove the blondies from the pan.
  • Let blondies cool before frosting. If you rush and add frosting to warm blondies you'll have a gooey sticky mess on your hands. I speak from experience!
  • You will not use a full box of cake mix. This recipe uses just over half a cup of mix. Store the leftovers in an ziploc bag to use for future baking.
