For best results, make sure all refrigerated ingredients are at room temperature before mixing so the batter emulsifies smoothly and bakes evenly, and avoid overmixing once the flour is added to keep the cupcakes tender. Gel food coloring works better than liquid for achieving bright red and deep black without thinning the frosting, and you can test colors on a small spoonful of frosting first to avoid over-tinting. If your frosting becomes too soft to hold shape while piping, chill it for 10–15 minutes and try again, and always cool cupcakes completely before decorating to prevent melted, sliding frosting. Store decorated cupcakes in a covered container in a cool place or the refrigerator and bring them to room temperature before serving so the cake is soft and the flavors are at their best.
