directions

Make the cake:

Alternate adding dry ingredients and milk to the butter mixture, beginning and ending with dry.

Gently fold in sprinkles.

Pour batter into prepared pan(s) and smooth the top.

Bake for 25–30 minutes or until a toothpick comes out clean. Cool completely before frosting.

Make the buttercream:
Beat butter until creamy. Gradually add powdered sugar, mixing well.

FAQs

Can I use nonpareils instead of jimmies?
Jimmies are best—nonpareils can bleed and tint the batter.

Can I use boxed cake mix?
Sure, but this homemade version tastes fresher and more flavorful.

Can I make the cake ahead of time?
Yes—bake and cool the layers a day in advance. Frost just before serving.

What’s the secret to a fluffy cake?
Room-temperature ingredients and not overmixing the batter!

Can I double this for a larger cake?
Yes—double all ingredients and use a sheet pan or larger rounds.
