Red Velvet cupcakes are classics. They usually consist of cocoa powder and red food colored (hence the name). This particular recipe also includes sour cream (to make them moist) and vanilla extract (to enhance the flavor.) Once you have combined these ingredients, along with the other ones, baked them and allowed them to cool, top with a homemade cream cheese frosting, as well as a few sprinkles. To make them even more festive, bake them in cute birthday or holiday-themed cupcake liners.
