Cinnamon red velvet cake from Sweetapolita adds a spicy kick to this classic American dessert. This unique batter contains both vinegar and mayonnaise which create a moist cake with a delicate crumb. No red velvet cake would be complete without a thick layer of cream cheese frosting. This recipe is spiked with cinnamon. You can also add a teaspoon of cinnamon whiskey for an extra kick.
