Red Velvet cupcakes are a classic treat that can easily be served at any function, big or small, fancy or casual. These are flavored with unsweetened cocoa powder, and also contain cake flour, kosher salt, an egg, sugar, vegetable oil, vanilla extract, buttermilk, baking soda, white vinegar, and of course, red food coloring (otherwise they would just be chocolate cupcakes.) In order to follow tradition, top them with cream cheese frosting. If you prefer, you can toss on a few sprinkles as well!
