Ingredients

Scale
  • 2 ½ cups (320 g) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (230 g) unsalted butter, softened
  • 1 ¾ cups (350 g) granulated sugar
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (240 ml) buttermilk, room temperature
  • ¾ cup (135 g) rainbow sprinkles, preferably non-melting
  • For the Funfetti Buttercream:
  • 1 cup (230 g) unsalted butter, softened
  • 4 cups (480 g) powdered sugar, sifted
  • 2–3 tablespoons (30–45 ml) heavy cream or whole milk
  • 1 teaspoon pure vanilla extract
  • ¼ cup (45 g) rainbow sprinkles

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
  2. In a large bowl, whisk together flour, baking powder, baking soda, and salt.
  3. Using a mixer, beat softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  5. Add dry ingredients in three parts, alternating with buttermilk, starting and ending with dry ingredients. Mix gently until combined; do not overmix.
  6. Fold in rainbow sprinkles gently with a rubber spatula.
  7. Divide batter evenly between prepared pans. Tap pans lightly to release air bubbles.
  8. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then turn out onto cooling racks to cool completely.
  10. For the buttercream, beat softened butter until creamy. Gradually add powdered sugar, mixing well.
  11. Add heavy cream and vanilla extract, beat until fluffy. Fold in sprinkles gently.
  12. Assemble cake by placing one layer on a plate, spreading a generous layer of buttercream on top, then adding the second layer.
  13. Frost top and sides evenly. Chill for 15 minutes, then smooth frosting if needed.

Notes

Use non-melting sprinkles to prevent color bleeding. Let cake layers cool completely before frosting to avoid melting buttercream. For gluten-free, substitute flour with a 1-to-1 gluten-free baking blend. Buttercream can be adjusted with cream or milk for desired consistency. Chill frosted cake for 10-15 minutes before smoothing final layer.
