Yes! To make this into a layer cake, double the recipe for the cake batter and for the frosting. Use two 8-inch round pans and divide the batter equally between the pans. Bake until the center of the cake is no longer wet looking ot a toothpick inserted into the center of the cake layers comes out with just a few crumbs on it. Cool the cakes completely before filling and frosting with the chocolate buttercream.
