Step 1: Level the Cake Layers
It’s important your cake layers are level, so your layer cake has stability. Make sure the cakes are completely cool before you level them. You can use a tool called a cake leveler, but I usually just use a serrated knife. Slice off the domed top so the top is flat. You can discard the bit you sliced off, or crumble it up and use it as garnish on top or around the cake. (Or enjoy the cake crumbles over ice creamโmy favorite!)

Step 2: Stacking
Decide on the frosting you want to use for your cake. Most of my layer cake recipes include the frosting recipe you’ll need for the cake. American buttercream or Swiss meringue buttercream are my 2 top choices for layer cakes. If using cream cheese frosting, I find it helpful to refrigerate it for at least 1 hour before using, since it isn’t as sturdy and stable as buttercream.
A cake turntable makes it easier to frost the sides. I usually use about 3/4 to 1 cup of frosting between each cake layer. To spread it, use an offset spatula, straight icing spatula, or a regular knife. Spread the frosting all the way to the edges.
Place the second cake layer upside down. This creates a flat base for the top layer to sit on. (If your cake is only 2 layers, you can place the 2nd (top) layer upside down OR right side up.) Check to make sure the cake layer is level all the way around. Then add another 3/4โ1 cup of frosting on top, again spreading it to the edges.

Place the top layer on top. You can place it upside down again if you want your cake to have a very straight look on the sides and a perfectly flat top, but I usually place the top layer right-side-up, so that there’s a bit of a curve to the edges.

Step 3: Crumb Coat
This is a very thin layer of frosting applied to the top and sides of the cake, which helps lock in any loose crumbs and adds stability to the finished layer cake. It also makes a nice smooth base for frosting and decorating. Use about another cup of frosting (240g) for that. Start moving the frosting from the top down the sides. Go around the sides with a bench scraperโit’s a really handy tool that makes easy work of smoothing out the sides. Refrigerate for 20 minutes to an hour to set the crumb coat.

Step 4: Finishing & Decorating
Once your crumb coat has set, you can finish the cake with a thicker layer of frosting. I recommend a straight spatula for this. You can use your bench scraper again for smooth sides, but I like a little texture.

If you used a cake turntable and want to transfer your cake to a serving platter or cake stand, it’s helpful to have a cake lifter tool and a second set of hands.
If you have extra frosting, you can use a piping bag and tip and add some decoration. Here I used the Wilton 1M tip to pipe a shell border around the top and bottom of the cake.

When it comes to cake decorating, I like to keep things simple. As much as I admire all those cake artists out there and marvel at their creations, I accept that cake artistry is simply not in my skill set! BUT there are ways you can make a beautiful layer cake, even if you lack artistic skill.
Take this rustic-chic naked cake, for example. Garnishing with fresh florals and berries adds simple, sophisticated eleganceโno piping tips, fondant, or modeling chocolate required.

A simple garnish of fresh berries and mint is one of my favorite ways to garnish a cake, because it’s so EASY, yet takes the cake to the next level.
You can also garnish with an ingredient used in the cake, such as toasted nuts on top of this carrot cake, or coconut and fresh pineapple on top of this pineapple coconut cake.

Description
Learn the basics of how to assemble and decorate a layer cake with this detailed guide. I follow the same steps whether I’m making a 2-layer, 3-layer, or 4-layer cake, and whether it’s a 6-inch cake or a 9-inch cake. Watch the video tutorial to see me demonstrate every step.
Ingredients
- baked cake layers (such as vanilla cake)
- frosting (about 4.5 cups (1080g) for a 2-layer 8- or 9-inch cake; 5โ6 cups (1200โ1440g) for a 3-layer cake)*
Instructions
- Level the Cake Layers: It’s important your cake layers are level, so your layer cake has stability. Make sure the cakes are completely cool before you level them. You can use a tool called a cake leveler or use a serrated knife. Slice off the domed top of your cakes so the top is flat. You can discard the bit you sliced off, or crumble it up and use it as garnish on top or around the cake. (Or enjoy the cake crumbles over ice creamโmy favorite!)
- Stack the Layers: Place the bottom layer right side up on a cake turntable or cake stand. Place 3/4 to 1 cup of frosting (anywhere between 180โ240g) on top. Using an offset spatula, straight spatula, or a regular knife, spread the frosting all the way to the edges of the cake. Place the second cake layer upside down evenly on top, which creates a flat base for the top layer to sit on. (*See end of this step if you are making a 2-layer cake.) Check to make sure it’s level all the way around. Then add another 3/4โ1 cup of frosting (180โ240g) on top, again spreading it to the edges. Place the top layer on top. You can place it upside down again if you want your cake to have a very straight look on the sides and a perfectly flat top, or you can place it right side up to have a bit of a rounded edge. *If your cake is only 2 layers, the 2nd/top layer can be upside down or right side up, depending if you want a straight edge or rounded edge on top of your cake.
- Add the Crumb Coat: A crumb coat is an extremely thin layer of frosting applied to the top and sides of the cake, which helps lock in any loose crumbs and adds stability to the finished layer cake. For a 3-layer cake, use about 1 cup of frosting (240g) for it. For a 2-layer cake, around 3/4 cup (180g). Spread it all over the top and sides. To smooth out the sides, run a bench scraper around the cake. Refrigerate uncovered for 20 minutes to 1 hour to set the crumb coat.
- Finish Decorating the Cake: Once your crumb coat has set, finish the cake with a thicker layer of frosting using aย straight icing spatula. You can use your bench scraper again for smooth sides, or keep the sides textured as shown in the video. If you used a cake turntable and want to transfer your cake to a serving platter or cake stand, it’s helpful to have a cake lifter tool and a second set of hands to lift and transfer it. If you have some extra frosting, you can fill a piping bag and add some decoration. Here I used the Wilton 1M tip to pipe a shell border around the top and bottom of the cake.
- When you have finished decorating your cake, it’s best to refrigerate it uncovered for at least 20 minutes before slicing and serving. Depending on the cake, you can refrigerate it for up to 4 to 6 hours. To store leftover cake or if you plan to transport the cake, I recommend a cake carrier because it keeps the cake fresh without touching or smearing the frosting.

- Amount of Frosting: In general, for an 8-inch or 9-inch round cake, you’ll use 3/4โ1 cup (180โ240g) of frosting between each cake layer, plus another 3/4โ1 cup for the crumb coat. After that, the amount of frosting depends on how thick you want the exterior layer and if you’ll want to add piping details to the cake. I usually use 4.5 cups (1080g) on a 2-layer 8- or 9-inch cake, and 5โ6 cups (1200โ1440g) on a 3-layer 8- or 9-inch cake. For a 3-layer 6-inch cake, use about 1/2 cup (120g) of frosting between each layer, 1/2 cup for the crumb coat (give or take), and 1โ1.5 cups around the top and sides to finish (3.5โ4 cups (840โ960g total).

Hi Sally, my cakes are not as good since I bought a convection oven. Do you have any tips? I’m so disappointed I love baking cakes and cookies.
Hi Mary! If you have to use convection/fan settings for baking, lower your temperature by 25 degrees F and keep in mind that things may still take less time to bake.
Thank you very much Sally, I am very grateful. You have been a great help to me. Now I have started to understand how to make cakes, I am very grateful. You give very good instructions that are easy to understand. God bless you very much.
I have made many layer cakes and 100% recommend this tutorial to any beginner to advanced baker! Great tips and info. Thanks Sally!
I’ve learned that if you use baking strips around the cake pans you won’t need to cut the top off to level the cake. The baking strips keep the sides of the pan much cooler, which allows the batter on the edges to continue to rise until its fully baked. Your layers will be flat and the edges will not be overly baked. If you don’t have baking strips, you can use folded strips of very wet t-shirt material wrapped in tin foil and fastened with a straight pin. But, the strips are a lot easier to use.
Sally,
Thanks for the tutorial. I do have a question though. I appreciate that you suggest how many cups of frosting you use between layers. Do you have a gram weight for that as I know it is easier and less messy to weigh than measure?
Hi Julie, the gram weights are in the recipe card!
Itโs in the recipe.

Iโm glad you included the crumb coat. Itโs a step most home bakers I know donโt do.
Great job with your email and tutorial video. I learned a lot.
Love your recipes.
So glad to read this, Betty!
Do you ever use a cake board? If so, when?
