Applying a Crumb Coat

Even a steady hand will drag crumbs into a final layer of frosting if the cake surface isn't sealed first. This thin barrier saves you the frustration of visible cake particles ruining the finish of your work.

Before you start

Wait for the cake to cool completely.

If the cake is even slightly warm, the frosting will melt and slide off the sides rather than gripping the surface.

  • bench scraper
  • cake turntable
  • cardboard cake round

The key technique

Dragging and Locking

Use a light hand to skim the frosting across the cake. The goal is to fill the gaps between crumbs, not to cover the cake with a thick layer of frosting.

Step by step

The method.

  1. Level the cake

    Use a serrated knife to trim any domed tops so each layer sits flat and level on the cake round.

  2. Apply the thin layer

    Spread a very thin, translucent layer of frosting over the top and sides of the cake. Use the offset spatula to catch loose crumbs as you move around the cake.

  3. Smooth the edges

    Use the bench scraper held at a 45-degree angle to gently pull the frosting around the sides, smoothing it out while pushing it into the crevices.

  4. Chill the cake

    Place the cake in the refrigerator for at least one hour. The frosting should feel waxy and firm to the touch before you proceed to the final coat.

Variations

Other turns to take.

The Jam Barrier

If your cake is particularly crumbly, spread a paper-thin layer of strained jam or a thin simple syrup over the cake before crumb coating to further lock down the surface.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Keep your spatula clean by wiping it on the side of your bowl frequently; never drag frosting with crumbs back into your main batch.

Tip

If you see a large chunk of cake break off, press it back into place with a dab of frosting before continuing.

Tip

Do not skip the refrigeration step; a soft crumb coat will pull right off when you try to apply the final layer.

Questions

The ones that keep coming up.

Can I use the same frosting for the final coat?

Yes, just make sure you use a fresh bowl of frosting that hasn't been contaminated by crumbs from the initial layer.

How do I know the crumb coat is done?

When you can see the color of the cake through the frosting, but no loose crumbs are shifting under your spatula, you have achieved the correct thickness.
