Here are some key tips to achieve light and fluffy cupcakes: Properly measure ingredients Cream together softened butter and sugar until the mixture becomes pale in color and feels light and fluffy. Incorporating air into the batter is important for achieving fluffy cupcakes. Beat the batter at medium speed just until the ingredients are combined. Avoiding overfilling cupcake liners, fill cupcake liners or pans about two-thirds full to allow room for the cupcakes to rise without overflowing. Preheat your oven to the recommended temperature.
