It’s best if you wait to frost the cake until it is completely cooled. To frost a two layer cake with crumb coat:
- Place first layer on serving plate, and scoop a large dollop of frosting in the center of the layer. Spread the frosting to the edges of the cake. Place second layer of carrot cake on top of the first layer. Scoop an ample dollop of frosting onto the center of the cake. Spread the frosting outward and down sides of cake, coating evenly. Let set for five to ten minutes, until the frosting has a chance to dry slightly. Wipe away any crumbs that have stuck to the edge of the plate. After the crumb coat has set, apply the rest of the frosting.
- For the cake shown in the photos, I used the traditional cream cheese frosting and applied it with a 16″ pastry tube and #4B star icing tip.
