Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) whole milk, room temperature
  • 1 cup (about 150g) rainbow sprinkles
  • For Frosting (optional):
  • 1 cup (227g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 1 ½ teaspoons vanilla extract
  • 24 tablespoons whole milk or heavy cream
  • Additional sprinkles for decorating (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. Using a mixer, beat softened butter and granulated sugar on medium-high speed until light and fluffy, about 3-5 minutes.
  4. Add eggs one at a time, beating well after each addition, then stir in vanilla extract.
  5. Alternately add dry ingredients and milk to the butter mixture, starting and ending with dry ingredients. Mix on low speed just until combined.
  6. Spoon about one-third of the batter evenly into the two prepared pans.
  7. Sprinkle ½ cup of rainbow sprinkles in the center of one layer.
  8. Carefully cover the sprinkles with the remaining batter, creating a ‘balloon’ of batter around the sprinkle center.
  9. Bake for 30-35 minutes. Test doneness with a toothpick near the edge; it should come out clean or with a few moist crumbs.
  10. Cool cakes in pans for 10 minutes, then transfer to a wire rack to cool completely.
  11. For frosting (optional): Beat softened butter until creamy. Gradually add powdered sugar, vanilla, and milk or cream until fluffy and spreadable.
  12. Layer and frost the cake as desired, finishing with extra sprinkles on top.

Notes

Use small, firm sprinkles for best results as they hold their shape during baking. Be gentle when layering batter over sprinkles to keep the center intact. Let the cake cool completely before slicing to prevent crumbling and preserve the sprinkle surprise. Room temperature ingredients help achieve a light, airy texture. Frosting is optional but recommended for added flavor and presentation.
