For best results, use room-temperature ingredients so the batter emulsifies smoothly and the cupcakes rise evenly; avoid overmixing after adding the flour to keep them tender. If you want a bakery-style swirl with both colors at once, place the pink and purple frosting side by side in the same piping bag to create a dual-color effect. Gel food coloring is preferred over liquid to keep the frosting from thinning. If your kitchen is very warm, briefly chill the frosted cupcakes (10–15 minutes) before serving so the buttercream holds its shape. Cupcakes can be stored covered at room temperature for 1 day or refrigerated up to 3 days; allow chilled cupcakes to come to room temperature before enjoying for the best texture.
