Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (227 g) unsalted butter, softened
  • 1 ¾ cups (350 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (240 ml) whole milk, room temperature (can substitute almond milk for dairy-free)
  • 2 teaspoons pure vanilla extract
  • ½ cup (about 80 g) rainbow nonpareil sprinkles
  • 1 cup (227 g) unsalted butter, softened (for frosting)
  • 4 cups (480 g) powdered sugar, sifted
  • 34 tablespoons (4560 ml) whole milk (for frosting)
  • 1 tablespoon vanilla bean paste
  • Pinch of salt (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 8-inch round cake pans and line bottoms with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, and salt. Set aside.
  3. Using a mixer, beat 1 cup softened unsalted butter and granulated sugar on medium speed until light and fluffy, about 4-5 minutes.
  4. Beat in eggs one at a time, fully incorporating each before adding the next. Scrape down sides as needed.
  5. Reduce mixer speed to low. Alternately add dry ingredients and milk, starting and ending with dry ingredients. Mix just until combined.
  6. Fold in vanilla extract and sprinkles gently with a spatula, being careful not to overmix.
  7. Divide batter evenly between prepared pans and smooth tops.
  8. Bake for 28-33 minutes, checking at 28 minutes with a toothpick; it should come out clean or with a few moist crumbs.
  9. Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
  10. For frosting, beat 1 cup softened unsalted butter on medium speed until creamy.
  11. Gradually add powdered sugar, milk, vanilla bean paste, and salt. Beat on high for 3-4 minutes until light and fluffy. Adjust milk for desired consistency.
  12. Place one cake layer on serving plate. Spread frosting generously over top.
  13. Add second cake layer and frost top and sides evenly.
  14. Refrigerate cake for 30 minutes to set frosting before slicing and serving.

Notes

Fold sprinkles in gently right before pouring batter to prevent color bleeding. Use an oven thermometer to maintain steady 350°F temperature and rotate pans halfway through baking for even cooking. Chill frosting if too soft before assembling. Vanilla bean paste adds authentic flavor and flecks; if unavailable, scrape seeds from a vanilla bean pod or increase vanilla extract.
