For best results, make sure all refrigerated ingredients for the batter and frosting are at room temperature so they combine smoothly, and avoid overmixing the batter after adding the dry ingredients to keep the cupcakes tender. Let the cupcakes cool fully before frosting to prevent the Nutella frosting from melting, and adjust the frosting texture with a bit more powdered sugar to thicken or cream to loosen as needed. Using hot coffee deepens the chocolate flavor without making the cupcakes taste like coffee, but you can substitute hot water if preferred. Store frosted cupcakes covered at cool room temperature for up to 1 day or in the fridge for up to 3 days, and let chilled cupcakes stand at room temperature for 20–30 minutes before serving for the softest texture.
