Use natural cocoa for classic red color, as Dutch-process can mute the hue and alter acidity needed for lift. Room-temperature eggs and buttermilk help the batter emulsify for a tender crumb. If you only have gel coloring, start with 1 teaspoon and adjust for vibrancy. Brushing layers lightly with simple syrup keeps the cake moist if making a day ahead. For ultra-smooth frosting, beat the butter and cream cheese until no lumps remain and ensure powdered sugar is fully sifted. If your kitchen is warm, chill the frosted cake for 20 minutes before slicing for cleaner cuts. You can bake the layers a day in advance, wrap tightly, and frost the next day for easier assembly.
