Ingredients

  • 1 box birthday cake cake mix
  • 1/3 cup melted butter
  • 2 large eggs
  • 1/4 cup heavy cream
  • 1/2 cup chopped white chocolate
  • 2-3 tbsp rainbow sprinkles

Instructions

  • Preheat oven to 350 F, grease or line a 9x9 baking pan and set aside
  • In a large bowl, stir together the cake mix, melted butter, eggs, and heavy cream
  • Fold in the chopped chocolate and rainbow sprinkles, reserving some sprinkles for the top if desired
  • Spread the batter into the prepared pan and bake in preheated oven 25-30 minutes, or until a toothpick inserted into the center comes out clean
  • Allow to cool at least 30 minutes before slicing and serving

Notes

  • Add extra sprinkles to the top for even more fun!
  • If you plan to use yellow cake mix, you can customize the sprinkles to suit any occasion! Red and green, orange and black, etc!
  • Don't overmix the batter or the blondies will be sort of tough.
