National Lemon Cupcake Day is celebrated on December 15, 2022. A lemon cupcake is a small lemon cake designed to serve one person, which may be baked in a small thin paper or aluminum cup. As with larger cakes, icing and other cake decorations, such as sprinkles, may be applied.
A standard cupcake uses the same basic ingredients as standard-sized cakes: butter, sugar, eggs, and flour. Nearly any recipe that is suitable for a layer cake can be used to bake cupcakes. Because their small size is more efficient for heat conduction, cupcakes bake much faster than a normal layered cake.
Cupcakes may be topped with frosting or other cake decorations. They may be filled with frosting or pastry cream. For bakers making a small number of filled cupcakes, this is usually accomplished by using a spoon or knife to scoop a small hole in the top of the cupcake. (With material from: Wikipedia)
