# How to Make It:

01 - Preheat oven to 350°F. Grease and flour two 9-inch round cake pans and line bottoms with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt until well combined.
03 - In a large bowl, beat butter and sugar with electric mixer until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating thoroughly after each addition. Mix in vanilla extract.
05 - Alternately add flour mixture and milk to butter mixture, starting and ending with flour. Mix until just incorporated.
06 - Gently fold rainbow sprinkles into batter using spatula. Avoid overmixing to prevent color bleeding.
07 - Divide batter evenly between prepared pans. Smooth tops and bake for 25-30 minutes until toothpick inserted in center comes out clean.
08 - Let layers cool in pans for 10 minutes, then turn out onto wire racks to cool completely before frosting.
09 - Beat butter until creamy. Gradually add powdered sugar, milk, vanilla, and salt. Beat until light, fluffy, and spreadable consistency.
10 - Frost top of one cooled layer, place second layer on top, and cover entire cake with remaining frosting. Decorate with additional sprinkles.

# Expert Suggestions:

01 -
  • The sprinkles create tiny pockets of sweetness throughout every bite
  • It tastes like childhood nostalgia but with actual butter and real vanilla
  • The frosting-to-cake ratio is absolutely perfect
02 -
  • Room temperature ingredients prevent the batter from curdling or separating
  • Overmixing after adding sprinkles will make your cake tough
  • Completely cool cake layers are non-negotiable or the frosting will melt
03 -
  • Sift your powdered sugar directly into the mixing bowl to prevent dusty clouds
  • Freeze your cake layers for 30 minutes before frosting for easier handling
