For each cupcake recipe, preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners. In a mixing bowl, combine the dry ingredients and set aside. In another bowl, cream together the butter and sugar until light and fluffy. Add the eggs and vanilla extract, mixing well. Gradually incorporate the dry ingredients and milk (or other wet ingredients) until just combined. Fill each cupcake liner about 2/3 full with batter and bake for 18-22 minutes or until a toothpick inserted in the center comes out clean. Allow to cool before frosting and decorating.
