Most cupcakes start with four basic ingredients: butter, sugar, eggs, and flour. These give the cake its soft texture and flavor. You can take any regular layer cake recipe and spoon the batter into small cups to make cupcakes instead of one big cake.
Because cupcakes are small, you can mix in extras like chocolate chips, berries, or a few chopped nuts. They bake faster than large cakes, so you watch them closely. After baking, you can top them with frosting, pipe decorations, or fill the centers with jam or cream using a spoon, a small knife, a pastry bag, or a special filling tool.
