When making caramel, use medium heat and swirl rather than stir to avoid crystallization, and pull it from the heat as soon as it reaches a deep amber to prevent bitterness. Room-temperature cream and butter reduce splattering when added, and cooling the caramel fully keeps it from melting the frosting. For lighter cupcakes, avoid overmixing once the flour is added, and ensure all ingredients are at room temperature. If your frosting is too soft, chill it 10–15 minutes; if too thick, whisk in a teaspoon of cream at a time. Store the cupcakes in an airtight container at cool room temperature for a day or refrigerate up to three days, letting them come to room temperature before serving for the best texture and flavor.
