Ingredients

12 tablespoons unsalted butter, softened

1 1/2 cups white granulated sugar

2 cups all-purpose flour

2 teaspoons baking powder

1/4 teaspoon salt

6 large egg whites

3/4 cup milk

2 teaspoons vanilla extract

3/4 cup Fruity Pebbles cereal, plus more for decorating

2 cups unsalted butter, softened (for frosting)

32 oz powdered sugar (2-pound bag)

24 tablespoons milk (for frosting)

2 teaspoons vanilla extract (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans.
  2. In a large bowl, beat 12 tablespoons butter and sugar until light and fluffy.
  3. In a separate bowl, whisk together flour, baking powder, and salt.
  4. Add egg whites and vanilla to the butter mixture and mix until combined.
  5. Alternate adding the flour mixture and milk, mixing gently until fully incorporated. Do not overmix.
  6. Fold in 3/4 cup Fruity Pebbles cereal until evenly distributed.
  7. Divide batter evenly between prepared pans.
  8. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 5 minutes, then transfer to wire racks to cool completely.
  10. For the frosting, beat 2 cups butter until fluffy. Gradually add powdered sugar on low speed until combined.
  11. Increase speed and whip until smooth. Add vanilla and 2–4 tablespoons milk as needed for spreadable consistency. Whip until light and fluffy.
  12. Frost the first cake layer, stack the second layer on top, and frost the entire cake.
  13. Decorate with additional Fruity Pebbles just before serving.

Notes

Do not overmix the batter to keep the cake tender.

Add cereal topping just before serving to maintain crunch.

For cupcakes, bake 18–22 minutes.

Store at room temperature for up to 2 days or refrigerate for up to 5 days.

Freeze unfrosted cake layers for up to 2 months.

Add a pinch of salt to frosting to balance sweetness if desired.
