For best color and texture, use gel food coloring (which won’t thin the batter or frosting) and bring all dairy ingredients to room temperature before starting to ensure a smooth, even crumb. Avoid overmixing once the flour is added so the cupcakes stay light and tender, and rotate your pan halfway through baking if your oven has hot spots for more even rise and color. If you want ultra-neat two-tone swirls, place both colored frostings side by side in a single piping bag or double-bag them and slide into a larger bag fitted with a tip, then practice piping a few rosettes on parchment before decorating the cupcakes.
