Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (226g) unsalted butter, softened (room temperature)
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (240ml) whole milk, room temperature (can substitute with almond milk for dairy-free)
  • ½ cup (90g) rainbow sprinkles (non-melting, jimmies style)
  • 5 large egg whites
  • 1 cup (200g) granulated sugar
  • 1 ½ cups (340g) unsalted butter, softened (cut into pieces)
  • 1 tsp pure vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch cake pans or line with parchment paper.
  2. Whisk together flour, baking powder, and salt in a medium bowl.
  3. Cream softened butter and sugar on medium speed for 3-4 minutes until pale and fluffy.
  4. Beat in eggs one at a time, fully incorporating each before adding the next. Stir in vanilla extract.
  5. Add flour mixture in three parts alternating with milk in two parts, starting and ending with flour. Mix just until combined.
  6. Gently fold sprinkles into the batter with a rubber spatula, avoiding overmixing.
  7. Divide batter evenly into prepared pans. Tap pans lightly to release air bubbles.
  8. Bake for 27-32 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then transfer to wire rack to cool completely.
  10. For the Swiss meringue buttercream: Combine egg whites and sugar in a heatproof bowl over simmering water. Whisk constantly until sugar dissolves and mixture reaches 160°F (70°C).
  11. Transfer mixture to mixer bowl and whip on high until stiff, glossy peaks form and bowl is cool to touch (about 10 minutes).
  12. Add softened butter pieces gradually on medium speed. Continue mixing until smooth, even if curdled at first.
  13. Stir in vanilla extract and a pinch of salt.
  14. Assemble cake by placing one layer on serving plate, spreading a thick layer of buttercream, topping with second layer, then frosting top and sides evenly.
  15. Optionally, sprinkle a few more confetti sprinkles on top for decoration.

Notes

Use jimmies-style sprinkles to prevent color bleeding. Softened but not melted butter is key for fluffy buttercream. If buttercream is too soft, chill for 10-15 minutes and re-whip before frosting. Room temperature eggs and milk improve batter texture and rise. Weigh batter between pans for even layers.
