Let’s put some fun in classic blondies by turning them into funfetti blondies with a buttercream frosting…That’s what happens when you got someone who wants birthday-cake cupcakes and someone else wants blondies….You mix both for a fun dessert!

Ingredients

For the blondies:

  • Vegetable oil or nonstick spray, for greasing pan
  • 205 grams (7 ounces wt) white chocolate
  • 120 grams (4 ounces wt) soft butter
  • 2 large eggs
  • 75 grams (6 tablespoons) granulated sugar
  • 10 ml (2 teaspoons) vanilla extract
  • 160 grams (1 cup/5.6 ounces wt) all-purpose flour
  • 5 ml (1 teaspoon) salt
  • 55 grams (2 ounces wt) color edible confetti

For the buttercream frosting:

  • 355 grams (1 1/2 cups) icing/confectioners sugar
  • 175 grams (6 ounces) soft butter
  • 5 ml (1 teaspoon) vanilla extract
  • 15-20 ml (3-4 teaspoons) heavy cream
  • Food coloring, a few drops as needed
  • Funfetti or colored sprinkles, for garnishing

Preparation

    1. For the blondies: Preheat oven to 154°C (310°F). Grease and 8×8 inch baking pan, or line with parchment paper. In a double-boiler or microwave oven, combine the white chocolate and butter and melt together. In a separate bowl, beat the eggs and granulated sugar together until smooth. Gradually mix together the melted chocolate and egg mixtures.
  1. Add the vanilla, flour, and salt; mix well. Add the funfetti and mix to blend. Pour into the prepared baking dish and smooth the top. Bake until the top is firm (the edges might brown a bit), 25-30 minutes. Remove from oven and allow to cool completely before frosting.

  2. For the buttercream frosting: In the bowl of an electric mixer, combine the butter and confectioners sugar. Beat until very smooth, 1-2 minutes. Add the cream and vanilla; mix well. Add a few drops of red food coloring to achieve a nice pink color.

  3. When the blondies are completely cool, frost thickly, and sprinkle generously with funfetti or colored sprinkles.
