Frosting a cake is the fun part. Once your cake is fully at room temperature, make your Vanilla Buttercream Frosting. We love the vintage vibe of waves in the frosting like we did with our chocolate cake but you can also crumb coat the cake and pipe the frosting onto the cake.
Place the first cake layer on a cake platter.
Spread a generous layer of frosting over the top, going to the edges.
Cover with the second cake layer with the top side down for a perfectly level cake surface.
Coat the top and sides of the cake with remaining frosting and use an offset spatula or spoon to create waves in the cake.
