  • 1 cup Cotton Candy Cap’n Crunch cereal (just the blue pieces)
  • 2 cups milk (divided)
  • 2 Tablespoons granulated sugar (divided)

Crushed Cereal

  • 1/3 cup Cotton Candy Cap’n Crunch cereal (just the pink pieces)
  • 1/3 cup Cotton Candy Cap’n Crunch cereal (just the blue pieces)

Cake Batter

  • 1 1/3 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 1/4 cup granulated sugar
  • 1/2 cup vegetable oil
  • 1/2 cup plain Greek yogurt
  • 1/2 cup pink cereal milk (from recipe above)
  • 1/2 cup blue cereal milk (from recipe above)
  • 1 egg
  • 1 1/2 teaspoon vanilla extract

Buttercream and Filling

  • 1 1/2 cup unsalted butter, softened
  • 1/2 teaspoon salt
  • 5 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 cup heavy cream
  • 4 ounces cream cheese
  • 3/4 cup heavy cream, whipped
  • Pink gel food coloring
  • Blue gel food coloring
  • Sprinkles (optional)

Instructions

  1. Make the Cereal Milk: Place the pink Cotton Candy Cap’n Crunch cereal into one bowl and pour 1 cup of milk over it, stirring to ensure the cereal is fully soaked. In another bowl, place the blue cereal and pour the remaining 1 cup of milk over it, stirring well. Let both bowls steep for 30-40 minutes to infuse the milk with the cereal flavor.
  2. Strain the Cereal Milk: Using a fine-mesh sieve over medium bowls, strain the milk from the pink cereal, discard the soaked cereal, and stir in 1 tablespoon of granulated sugar. Repeat this for the blue cereal milk, adding the remaining tablespoon of sugar. Set cereal milks aside.
  3. Preheat Oven and Prepare Pans: Preheat your oven to 350ºF (175ºC). Line three 6-inch round cake pans with parchment paper and spray them with nonstick cooking spray for easy release.
  4. Crush the Cereal: Using a food processor or a zip-top bag and rolling pin, finely crush the designated pink cereal pieces. Transfer to a small bowl. Repeat the process for the blue cereal pieces into a separate bowl. Set aside.
  5. Mix Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and granulated sugar until fully combined.
  6. Add Wet Ingredients: To the dry mixture, add vegetable oil, Greek yogurt, egg, and vanilla extract. Stir the mixture until combined; batter will be thick and dough-like.
  7. Divide and Flavor Batter: Split the batter evenly into two separate bowls. To one bowl, add pink cereal milk and crushed pink cereal, mixing gently until just combined. To the other bowl, add blue cereal milk and crushed blue cereal, stirring until just combined.
  8. Layer the Batter: Alternating spoonfuls of blue and pink batter, divide both batters equally across the three prepared cake pans. This creates a fun marbled and layered effect inside the cakes.
  9. Bake the Cakes: Place the pans in the oven and bake for 28-32 minutes. Check doneness by inserting a toothpick into the center of the cakes; it should come out clean. Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
  10. Make the Buttercream Filling: In the bowl of a stand mixer fitted with the paddle attachment, beat softened butter and salt on high speed until fluffy, about 3 minutes. Gradually add powdered sugar, a cup at a time, blending fully. Increase mixer speed and beat for an additional 3 minutes for a light texture. Add vanilla extract and heavy cream one tablespoon at a time, beating for about 2 minutes until fluffy and creamy.
  11. Prepare Cream Cheese Filling: Remove 1 cup of the buttercream and set aside for filling. Transfer the remaining buttercream to a separate bowl and return it to the mixer. Beat cream cheese and reserved buttercream together until smooth. Add half of the whipped heavy cream and beat gently to combine. Fold in the remaining whipped cream carefully by hand.
  12. Assemble the Cake: Place one cake layer on a cake plate or pedestal. Spread one-third of the cream cheese filling evenly over the layer. Repeat with the remaining cake layers and filling, finishing with a layer of filling on top. Chill the assembled cake in the freezer for 1 hour to firm up.
  13. Frost the Cake: Once chilled, frost the entire cake using the plain buttercream. Return the cake to the refrigerator for at least 30 minutes to allow the buttercream to set.
  14. Color and Decorate Buttercream: Divide the reserved buttercream into three bowls. Tint one bowl pink and another blue with gel food coloring, leaving the third bowl white. Remove the cake from the fridge and use an offset spatula to apply thick patches of pink and blue buttercream around the cake, filling in some areas with white to create a watercolor or marble effect. Smooth the buttercream as the colors blend, applying more buttercream to cover any gaps as desired.
  15. Pipe and Add Sprinkles: Transfer the remaining white buttercream to a pastry bag fitted with a star tip (Wilton 1M recommended). Pipe a decorative border of stars around the top edge of the cake. Sprinkle with desired sprinkles for a festive finish. Refrigerate the cake until ready to serve.

Notes

  • Make sure to let the cereal steep fully to get the best flavor infusion for the cereal milk.
  • Alternating spoonfuls of pink and blue batter creates a beautiful marbled cake appearance when sliced.
  • Using a stand mixer with a paddle attachment yields the creamiest buttercream consistency.
  • Chilling the cake before frosting helps prevent the buttercream from melting and keeps decorations crisp.
  • Gel food coloring is preferred as it does not affect the texture of the buttercream.
  • Sprinkles add an extra fun touch but are optional based on preference.
