For best results, avoid overmixing the batter to keep the cupcakes tender and watch bake time closely since chocolate cupcakes can dry out fast when overbaked. If the caramel filling seems too runny, let it cool a bit longer or briefly chill it so it thickens enough to stay in place. Room-temperature ingredients help the batter and frosting come together more smoothly, and sifting powdered sugar and cocoa powder prevents lumps in the frosting. Store cupcakes in an airtight container at room temperature for up to 2 days, or refrigerate if your kitchen is warm, letting them come back to room temperature before serving for the best texture and flavor.
