Can I make the cake layers in advance?

Yes, you can bake the sponges a day ahead of time, allowing them to cool completely before wrapping them tightly in parchment and plastic. Storing them at room temperature overnight actually helps the crumb settle, making the layers easier to slice and stack the following morning. Just ensure they are kept in a cool, dry place away from direct sunlight.

How should I store leftover cake?

Leftover slices should be kept in an airtight container or under a cake dome in the refrigerator for up to five days. To maintain the best texture, I recommend taking the cake out of the fridge thirty minutes before you plan to eat it. This allows the butter in the sponge and the frosting to soften back to a creamy, palatable consistency.

Why did my sprinkles bleed into the batter?

Colors usually bleed when you use nonpareils or if you over-mix the batter after adding the sprinkles. The friction of the mixer can break the sugar coating on the sprinkles, causing the dye to streak into the pale batter. Always fold them in gently by hand with a spatula as the very last step before the pans go into the oven.

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

While you can use all-purpose flour, the resulting cake will have a coarser crumb and a slightly tougher texture. Cake flour has a lower protein content, which is what gives this specific recipe its signature velvet-like feel. If you must use all-purpose, sift it several times with two tablespoons of cornstarch to mimic the lightness of cake flour.

Why is my frosting too runny to stay on the cake?

Runny frosting usually happens if the butter was too soft or if the kitchen is too warm while you are working. You can fix this by adding more sifted confectioners' sugar a half-cup at a time until the desired thickness is reached. Alternatively, placing the entire bowl of frosting in the refrigerator for twenty minutes can help the butter firm up enough for easy spreading.

Can this recipe be frozen for later?

Both the unfrosted sponges and the fully decorated cake freeze remarkably well for up to three months. Wrap the layers or the entire cake in several layers of plastic wrap and a final layer of foil to prevent freezer burn. Thaw the cake slowly in the refrigerator overnight before bringing it to room temperature for the best flavor and texture.

Instructions

Prepare the workspace. Preheat oven to 350°F, grease three 8-inch pans, and line them with parchment paper.
Sift dry ingredients. Whisk together cake flour, baking powder, baking soda, and salt in a bowl until aerated and lump-free.
Cream butter and sugar. Beat softened butter and sugar on high speed for five minutes until pale and fluffy.
Build the emulsion. Lower speed and incorporate vegetable oil, whole eggs, egg whites, and vanilla until uniform.
Fold in batter. Alternate adding flour mixture and buttermilk in three additions, then gently fold in rainbow sprinkles.
Bake the sponges. Divide batter among pans and bake for roughly twenty-five minutes, tenting with foil if browning too quickly.
Cool the cakes. Rest cakes in pans for twenty minutes before turning onto a wire rack to cool completely.
Whip the buttercream. Beat softened butter with confectioners’ sugar, heavy cream, and vanilla until stiff and spreadable.
Apply crumb coat. Stack layers with frosting, then apply a thin base layer and chill for thirty minutes to set.
Finish the design. Spread remaining buttercream over the cake using an offset spatula to create rustic swirls and ridges.

Notes

Use long jimmies rather than round nonpareils to prevent colors from bleeding into the cake batter.
Always bring your butter and eggs to room temperature to ensure a smooth, stable emulsion.
Use a digital kitchen scale to measure flour precisely, as over-packing cups can result in a dry sponge.
Ensure the cakes are completely cold to the touch before frosting to prevent the butter from melting.
