For best results, ensure all refrigerated ingredients for the batter are at room temperature so the cupcakes rise evenly, and avoid overmixing once the dry ingredients are added to keep the texture tender. If your raspberry puree is very juicy, add it gradually to the buttercream so it doesn’t become runny, and chill the frosting for a few minutes if it softens too much while piping. Let the frosted cupcakes sit at cool room temperature for 15–20 minutes before serving to bring out the chocolate and raspberry flavors, and store leftovers in an airtight container in the fridge for up to three days, allowing them to come back to room temperature before eating.
