Instructions

  1. For the Funfetti Cake Layers: Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans and line them with parchment paper rounds. Set aside.
  2. In a large bowl, sift together cake flour, baking powder, baking soda, and salt. Set aside.
  3. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed for about 1 minute until smooth and creamy.
  4. Gradually add the sugar, and continue beating on high speed for 2 minutes.
  5. Reduce the mixer speed to low, then add the beaten egg whites, a little at a time, making sure to scrape down the sides of the bowl frequently.
  6. In a measuring cup, combine milk, sour cream, oil, and vanilla. Stir until evenly mixed.
  7. Add the flour mixture to the wet ingredients in three additions, alternating with the milk mixture, starting and ending with the flour. Mix until just combined. Gently fold in the sprinkles.
  8. Divide the batter evenly between the two prepared pans, smoothing the tops.
  9. Bake for 25-30 minutes, or until the cakes are lightly browned around the edges and a toothpick inserted in the center comes out clean.
  10. Cool the cakes in the pans for 15 minutes, then invert them onto cooling racks to cool completely.
  11. For the Cream Cheese Frosting: Beat the cream cheese and butter on medium-high speed until smooth, about 2 minutes.
  12. Reduce the speed to low, gradually adding the sifted confectioners’ sugar. Add the salt and milk, and beat until combined.
  13. Increase the speed to high and beat for 1-2 minutes, or until the frosting is fluffy.
  14. Reserve 1/2 cup of the frosting in a piping bag fitted with a star tip for decoration.
  15. Assembly: Using a serrated knife, slice each cooled cake layer in half horizontally to create four even layers.
  16. Place one cake layer on a cake stand or large plate. Spread 2/3 cup of frosting over the top.
  17. Add the second layer of cake, then repeat the frosting process until all layers are stacked.
  18. Cover the top and sides of the entire cake with the remaining frosting. Use the reserved frosting in the piping bag to decorate the top with stars or swirls.
  19. Gently press sprinkles around the sides of the cake.
  20. Allow the cake to set for 20 minutes before slicing and serving.
