For the most vibrant red, use gel coloring and adjust based on your cocoa brand, as darker cocoa may mute the hue. Ensure all cold ingredients are at room temperature to prevent a dense crumb and to help the batter emulsify. Brown the butter carefully; once the milk solids turn amber and smell nutty, remove from heat immediately to avoid bitterness, and cool fully before beating into the frosting to prevent splitting. If your frosting seems loose, chill it for 10 minutes and rewhip, or add a few tablespoons more powdered sugar. The cake layers can be baked a day ahead, wrapped well, and refrigerated or frozen for cleaner stacking and easier frosting.
