Ingredients:

  • 3 cups (360g) all-purpose flour
  • 1 ½ cups (300g) granulated sugar
  • 1 tbsp (12g) baking powder
  • ½ tsp (3g) salt
  • ¾ cup (170g) unsalted butter, softened
  • 3 large eggs
  • 1 cup (240ml) buttermilk
  • 2 tsp (10ml) pure vanilla extract
  • ½ cup (115g) unsalted butter, softened
  • 2 cups (240g) powdered sugar
  • 2 tbsp (30ml) heavy cream
  • 1 tsp (5ml) vanilla extract
  • 12 oz (340g) white candy melts
  • 1 tsp (5ml) coconut oil
  • ¼ cup (30g) rainbow sprinkles

Instructions:

  1. Preheat oven to 350°F (175°C). Grease and flour a 9-inch cake pan.
  2. Cream butter and sugar until pale and fluffy. Beat in eggs and vanilla.
  3. Alternatingly add dry ingredients and buttermilk, mixing until just combined.
  4. Bake for 25 minutes or until a toothpick comes out clean. Cool completely.
  5. Pulse the cooled cake in a food processor for 10 seconds until it resembles fine sand.
  6. Whip the frosting ingredients (butter, powdered sugar, heavy cream, and vanilla) together until smooth and velvety.
  7. Add frosting to the cake crumbs one tablespoon at a time.
  8. Fold gently with a spatula until the dough holds its shape when squeezed—it should feel like soft play-dough.
  9. Roll into 1-inch spheres and place on a parchment-lined tray.
  10. Chill the balls in the freezer for 15 minutes to firm up.
