Once cakes are completely cooled, use a serrated knife to slice off the dome center of the cake. When leveling cakes, you don’t need to cut off the entire dome, but just enough to let it sit flat. You can fill in the uneven areas or gaps with extra frosting once you stack your cake.
Place a dollop of frosting on your turntable. Then place the cake board exactly centered in the middle of the turntable. Place another dollop of frosting on your cake board. Center your first cake layer in the very center of the cake board. The frosting serves as a glue to keep your cake from moving while frosting.
Spoon about ¾ cup of frosting on top of your first cake layer. Using your icing spatula, spread the cream cheese frosting from the center of the cake towards the edges, making the frosting as level as possible. Frosting should be about ¼ inch thick.
Stack the next cake layer upside down on top of the first layer, making sure it’s centered and level. I like to place the second and third cakes upside down because the bottom is completely flat and makes for a more level cake. You can press the cake in the areas where it is uneven to make it lower if needed. Repeat with another layer of frosting.
Add the last layer of cake upside down. To crumb coat the cake, add a dollop of frosting on top and spread it out in a very thin layer, pressing the frosting from the center to the edges. Spread some frosting on the sides of the cake in a very thin layer, until all the bare spots are covered.
Take your bench scraper and hold it perpendicular to the sides of the cake to scrape the frosting in an even layer until smooth, as you spin the turntable. If there are any gaps, add a little more frosting and scrape the sides again. Use the bench scraper to smooth the top of the cake as well.
Spin the cake around to check that the cake is level and straight along the sides. You can adjust the cake with the bench scraper if needed and smooth the sides again.
Place the crumb coated cake in the refrigerator for at least 30 minutes to allow the frosting to chill and set, and no longer sticky.
