Can I use all-purpose flour instead of cake flour?

While all-purpose flour will work in a pinch, the texture will be significantly heartier and less delicate. If you must use it, replace 2 tablespoons of flour from every cup with cornstarch and sift it three times to mimic the protein level of cake flour. This helps maintain some of the softness required for a successful layer cake.

Why did my sprinkles sink to the bottom of the cake pans?

Sprinkles usually sink because the batter is too thin or the sprinkles are too heavy for the structure. This recipe uses a thick buttermilk batter specifically designed to suspend the jimmies throughout the bake. Ensure you are not over-mixing, which can thin the batter, and use lightweight jimmies for the best distribution.

How do I store the finished cake to keep it fresh?

The frosted cake can be stored at room temperature in a cake carrier for up to four hours for immediate serving. For longer storage, keep it in the refrigerator for up to five days, but always bring it back to room temperature before eating. Cold cake often feels dry because the butter in the batter and frosting has hardened.

Can I make the cake layers in advance and freeze them?

Yes, these layers freeze beautifully when wrapped tightly in several layers of plastic wrap and aluminum foil. You can freeze them for up to three months and thaw them overnight in the refrigerator before assembling. Many bakers find that freezing the layers actually makes them easier to handle and level during the stacking process.

What is the best way to get a perfectly white frosting?

To get a stark white buttercream, use clear vanilla extract and beat the butter for at least five minutes before adding the sugar. This aerates the butter, turning it from yellow to ivory. You can also add a tiny, microscopic drop of violet food coloring to the finished frosting to neutralize any remaining yellow tones from the butter.

My cake layers are domed on top, how can I fix this?

Domed tops are a natural result of the cake rising in the oven, but they can be prevented by using even-bake strips around the pans. If your cakes still come out with a dome, simply use a long serrated knife to carefully slice off the rounded portion once they are cool. This creates a flat surface that is essential for stable stacking and even frosting layers.

Instructions

Prepare the oven. Preheat the oven to 350°F (177°C) and line cake pans with parchment paper.
Combine dry ingredients. Whisk together the cake flour, baking powder, baking soda, and salt in a large bowl.
Cream butter and sugar. Beat the softened butter and sugar on high speed for five minutes until pale and voluminous.
Emulsify the fats. Add the vegetable oil, eggs, egg whites, and vanilla, mixing until the batter is smooth.
Mix the batter. Alternately add the dry ingredients and buttermilk in three additions, mixing on low speed until combined.
Fold in sprinkles. Gently fold the rainbow jimmies into the batter using a silicone spatula.
Bake the layers. Divide batter into pans and bake for 25 minutes or until a toothpick comes out clean.
Cool the cake. Let cakes rest in pans for 20 minutes before inverting onto a wire rack to cool completely.
Whip the frosting. Beat butter, confectioners’ sugar, and heavy cream until light, airy, and spreadable.
Assemble and frost. Level the cakes, stack with frosting layers, apply a crumb coat, and chill before final frosting.

Notes

Use room temperature ingredients to prevent the batter from curdling.
Always use jimmies rather than nonpareils to prevent colors from bleeding into the batter.
The crumb coat is essential for achieving a professional finish without loose cake debris.
Use a kitchen scale to measure flour accurately to ensure the cake does not turn out dry.
