How to Crumb Coat a Cake
Crumb coats are important in creating beautiful cake designs. A crumb coat is a thin coat of frosting around the cake that traps in crumbs so that your final layer is clean, smooth, and pretty.
- 1+ cake layer(s)
- Frosting of choice
Prepare: Prepare your cake layer(s) and buttercream. If your cake has layers, layer it with frosting. Set aside a small clean bowl for excess frosting.
Crumb coat: Dollop some frosting on top of your cake. Using an offset spatula, spread the frosting all over the cake, including on the sides. Scrape off any excess frosting into your prepared bowl.
Using your excess frosting, fill in any bare spots. Using a bench scraper, scrape off excess frosting from the sides and the top.
If any bare spots remain, repeat step #3. The coat of frosting should be thin and should cover the whole cake, but it doesn't have to look perfect.
Freeze: Place the cake in the freezer for 15-20 minutes. It should be cold to the touch.
Finish the cake: Finish with your final coat of frosting and any decorations.
