These funfetti birthday cake blondies are sweet, buttery and packed full of sprinkles. They're made from scratch and don't require any cake mix!
Yield: 16 bars
  • ½ c. (1 stick) unsalted butter
  • 5 oz. white chocolate, chopped*
  • ½ c. granulated sugar
  • ¼ c. brown sugar
  • 2 eggs
  • 2 tsp. vanilla extract
  • 1 c. + 2 tbsp. all-purpose flour
  • ¼ tsp. baking powder
  • ½ tsp. salt
  • ½ c. sprinkles (anything but nonpareils)**
  • 1 oz. white chocolate, chopped (optional)
  1. Preheat oven to 350 degrees. Line an 8x8" baking pan with parchment paper or foil, lightly grease, set aside.
  2. In a medium size microwave safe bowl (or glass measuring cup), add the butter. Heat until partially melted, then add the white chocolate. Microwave on medium power in 15 second intervals, stirring until melted and smooth. Pour into a large mixing bowl or the bowl of a stand mixer.
  3. Add the sugars, eggs and vanilla, mix until combined.
  4. In a separate mixing bowl, whisk together the flour, baking powder, and salt. Gradually add to the wet ingredients, mixing just until combined. Fold in sprinkles (and extra chunks of white chocolate if desired) by hand.
  5. Pour into prepared pan and place in oven to bake for 25-30 minutes or until top is set and golden brown. Remove from oven and allow to cool in the pan for 45 minutes before removing and slicing.
*Please use high quality white chocolate, both for the taste and texture to be correct. I prefer using Ghirardelli white chocolate baking bars. You'd need 10 (small) individual squares, or 1¼ bars for 5 ounces.
**I prefer a mix of sprinkles, mainly for the texture. Just don't use nonpareils, they'll bleed when you mix them in the batter. They're perfectly fine to sprinkle on top.
-Frosting is not needed for this recipe. Because they are made with white chocolate, they are naturally sweet. I'd stick with a sugar cookie bar recipe if you want to make frosting :)
