8. Frost like a professional.
Put a small dollop of frosting in the center of the cake plate, and place the first cake layer on top. This will keep the cake from moving as you work. Use an offset spatula to frost the top, add the next layer, then coat the whole cake with a thin layer of frosting. (This “crumb coat” holds loose crumbs in place.) Place the cake in the freezer for 15 minutes, then remove and finish frosting, starting with the top, then the sides.
