Frost the layered cake: Spread a couple of tablespoons of frosting at base of cake plate or cake stand (this will help hold the cake in place). Place one cake upside down onto the frosting. Spread an even layer of frosting on top of layer, about 1/2" thick. Top other cake onto frosting (you can place layer upside down or bottom side down and shave off any extra round height from top if you'd like) and frost rest of cake. I've been using an
off-set spatula for frosting cakes and love it.
