How do you stack a two tier cake? This simple step by step tutorial answers all your questions about how to bake, fill, stack, and decorate a two tier cake from start to finish! It’s not as hard as you think!
Stacking a two tier cake starts with baking a cake that has the stability to be stacked. That means you need a cake that can hold the weight of a cake on top of it.
A light and airy cake like an angel food cake is not your best choice for a stacked cake because it is likely to collapse or droop under the pressure.
As a trained pastry chef and owner of a home based custom cake business for 5 years I have made lots and lots of cakes! If you love decorating cakes make sure you read my 10 ways to make your cakes look more professional, and how to decorate a cake with flowers!

What kind of cake is best?
A more dense cake is a great choice, but it doesn’t have to be your only choice. You can make a more fluffy cake recipe and still be able to stack it as long as you bake your layers thick enough.
One of my favorite recipes to use to stack a cake is this easy one bowl vanilla cake recipe. It is a little more on the dense side but the flavor is so good and it stacks beautifully! This is the recipe you will find in the recipe card below.
I also have this chocolate cake recipe but it is a little more on the fluffy side. If you’re a beginner at stacking two tier cakes, I would say start with the vanilla recipe!
The recipe that I used for this tutorial is my cookie butter cake recipe. It’s sturdy enough to be stacked, and SO insanely delicious!
What buttercream recipe should I use?
Go with this classic American buttercream recipe. It pipes really nicely and will also crust up perfectly for stacking. You will have to double the recipe to have enough to stack a cake. Or triple it if you like a lost of frosting.
Baking pans to use
These wilton baking pans are my absolute favorite baking pans to use wether or not I am stacking a cake. They are durable, retain heat really well, and since the sides are straight, you always get good straight sides when baking.
I have them in all four sizes- but when you stack a cake you need multiples of the same size pan. So that means 3 8″ round cake pans and 3 6″ round cake pans. Sometimes Michaels has a sale and you can get the pans for really cheap, so be on the lookout!
I always like to bake and stack my cakes in 3 layers because it gives the cake height which makes is more professional looking. You can read about some other ways to make your cakes look more professional here.
Disposable Aluminum pans
I don’t love using disposable aluminum pans for stacking. I know they are the cheaper option but they really aren’t very sturdy and won’t yield the best results. Invest in good baking pans and you’ll use them for years!
Cake Size You need
A two tier cake means you need two cakes (composed of layers) in two different sizes. The standard size is usually a 6″ cake stacked on top of a 8″ cake and it feeds about 40-50 people depending on how big you cut the slices.
Remember it may not look like it can feed that many people but stacked cakes are taller than regular cakes which means you can cut the slices thinner and still have a nice slice of cake. Sometimes I’ll cut a slice and because it is so tall, then cut it in half to serve.
The difference between tiers and layers
This confuses people sometimes.
Tiers and layers are two different things. There are multiple layers of cake inside one tier. A tier of cake is composed of multiple layers of cakes. Does that make sense?
Each tier of the cakes I make usually have three layers of cake in it. Sometimes my 6″ cakes will only have 2 layers if they are really thick and the height is there without needing an extra layer of cake.
Tools you’ll need to stack your cakes:
- Baking Pans (see above)
- a cake leveler or long serrated knife
- cake turntable
- offset spatula
- cake boards in multiple sizes (see below)
- bubble tea straws
- bench scrapers
- clean spray bottle
- buttercream– have this at the ready!
- piping tips and bags for decorating (optional)
Notes on the tools you need:
Cake boards- Using two different size boards when frosting and filling is helpful because it will allow you to lift the cake up and move around. Also it will catch any frosting that falls so the turntable doesn’t get messy.
You want to have one that is 2 inches larger than your cake, so in this case a 10″ and one that is the same size as your cake, an 8″- for the bottom cake.
As well as an 8″ cake board and a 6″ cake board for the smaller cake.
So let’s recap, you need:
- 1, 10″ cake board
- 2, 8″ cake boards
- 1, 6″ cake board
If you are planning this for a fancy party or want the cake to be presented on something nicer than a cake board then you can buy one of these cake drums and use it to act as your 10″ cake board.
A cake drum is different than a cake board.
A cake drum is thicker, nicer, and more sturdy, and is usually what cakes are presented on for parties and things if not on a cake stand.
A cake board is just a round piece of cardboard that is not as sturdy as a drum. So if you are making this to deliver or for somebody, I suggest making it on a cake drum.
Assembling the cake layers
Start with a flat top
When the cakes are cool you will need to cut off the tops to make them flat because you can’t stack a cake that doesn’t have a flat top.
You can use these baking strips to bake your cakes flat, or some other hacks swirling around the internet but I prefer to just cut off the domed top. Keep the scraps too! They make for a tasty breakfast treat.
I use either a cake leveler or a long serrated knife. If you are a beginner I say go with the cake leveler, it is SUPER easy to use. It’s basically like a saw for your cakes. The only thing with it is that if the outside of your cake is a little crisp, the initial cut into the cake is a little hard. But it is totally doable and the best way to start!
Now you should have between 5-6 cake layers with flat tops.
You will need a turntable, offset spatula, some cake boards, and buttercream.
Place a 10″ cake board on the turntable. Dab a little but of buttercream in the middle of the cake board- just a tiny bit.
Then place the 8″ cake board on top and press down to seal.
Smooth about 1 tablespoon of buttercream over the 8″ cake board and place your first layer of your 8″ cake on top.
Fill the cake with buttercream:
You can either use a piping bag, or you can just use your offset spatula to spread an even layer of buttercream over the cake layer. If you are using piping bag– pipe a border of buttercream around the cake 1/4 inch in and then fill from there.
If you are using the spatula, start by placing down about 1/4 -1/3 cup of buttercream in the center, and work your way out. Stop 1/4 inch from the border.
Once you have an even layer of frosting, take another cake layer and flip it over so that the bottom is now the top. Place it down over the layer of buttercream. Yes, the cut side should be the side on top of the buttercream.
Doing that ensures you have more of a flat top!
Repeat the process of filling with buttercream and laying the last layer just like you did before with the bottom of the cake flipped over.
Frosting the cake
First we are going to start with a crumb coat.
A crumb coat is exactly what it sounds like- a coat for crumbs haha. No really, its just a light coating of frosting over your cake to seal in the crumbs so that when you add another layer of frosting, the crumbs won’t be seen or make your cake look messy.
Crumb coat your cake
Using an offset spatula, scoop up some frosting and smear it on the sides of your cake, turning your turntable as you go. Work your way from bottom to top, covering the cake with just a light coat of frosting.
Make sure to scrape off the back of your spatula onto the sides of the bowl before going in for another scoop fresh buttercream- this will leave those pesky crumbs from getting into your buttercream!
Here’s a link to a video for you, if you need more of a visual!
Pick up the cake, and this is where the larger cake board comes in handy- and place it in the freezer for 15 minutes to seal the crumbs.
Repeat this process with an 8″ cake board, a 6″ cake board and your 6″ cake layers.
When your 6″ cake is ready to go into the freezer, take the 8″ one out. Now its time for the top coat of frosting.
Frosting Top Coat
Essentially its the same thing you did before with the crumb coat, just with more frosting.
I like to start on the sides from the bottom and work my way up with my spatula, going around and around, spinning and spreading as I frost. Don’t worry if you’re making a mess or if it is not perfect- this takes a lot of practice!
When the cake is covered (you don’t want to see any spots of cake) and you get up to the top, stop and switch from the spatula to the bench scraper.
How to hold the bench scraper:
Making sure your wrist is straight and the bench scraper is straight against the cake- hold it in one place and spin your turn table.
If you notice some places need more frosting, add in a little bit and continue spinning with the bench scraper up against the cake. It will even it out.
The cake sides should be more or less smooth now. Don’t worry if its not perfect or if it takes you a few tries. It really does take patience and practice.
Now though there should be a lip of frosting at the top of the cake that is taller than the cake. Leave that alone and fill in the top of your cake with more frosting.
Now using your bench scraper or spatula on an angle- smooth that lip from the outside of the cake to the inside.
Heres another video on how to do it because really it’s best to watch to understand! You can fast forward to exactly 5 minutes in and you’ll see exactly what I’m talking about!
How to have smooth cake edges
To create REALLY smooth edges, I am gonna tell you a trick I learned while working in a cake decorating shop.
Fill a food safe, clean water bottle with clean water and lightly spray your just frosted cakes. YES YOU HEARD ME RIGHT.
Spray your cake with water and then take the bench scraper and lightly go over all the bumps and edges. Then watch them disappear. Do this on the turntable one cake at a time, spinning as you go.
Go ahead I’ll wait.
Repeat with both cakes!
OK so now we have two beautiful cakes. 1 8 inch cake with 3 layers and 1 6 inch cake with either 2 or 3 layers.
LETS GET THIS STACKING STARTED!!
Stacking a two tier cake
You will need:
- Bubble tea straws or wooden dowels
- Belief in yourself that you can do this
Let me first start off by saying that regular straws will not work. You need the thick bubble tea ones like these. I prefer these over the wooden dowels. They are thicker, easier to cut, and don’t run the risk of getting wooden shards in your cake.
I also suggest that if you want to present this cake on a cake stand, you should move the 8″ cake to it now.
This is another reason why we use the 10″ cake board. Because now you have the 8″ one underneath, you can slip the cake off the 10″ board and onto a cake stand.
How to move a cake from cake board to cake stand
Using a large offset spatula (or the small one if that’s all you have) stick it between the 10″ and 8″ cake boards and carefully lift. Have your other hand at the ready to lift it up and shift the weight into your hand. Then place it on the cake stand.
This picture shows how to lift it using the spatula just with a smaller cake.
Now were ready to stack a two tier cake!
The bubble tea straws are going to be what is supporting the weight of the top tier on top of the bottom tier. Because of this, they need to be strategically placed.
You want to make sure that they are evenly placed under the weight of the top tier. Place the straws too close to each other and the weight won’t be evenly distributed. Too far, and you will see the straws coming out from the top of the bottom tier.
You have to make sure that the straws are placed under the top tier so that it can support the top tier and no-one knows it!
I like to place 4 evenly distributed straws in a square shape and then sometimes one in the middle of that if my cake is 10″ or larger. Since this is an 8″ cake we are going with 4 straws. This makes sure that the top tier’s weight is balanced.
How to place the straws on the bottom tier
Poke each straw into the cake until it hits the bottom, then mark where the top of the cake is either with frosting or eyeball it. Pull the straw back up and cut off the top with a scissor. Push the straw back in. Make sure that it is either level with the top of the cake or a little bit under.
You do not want the straw to be taller than the cake otherwise your top tier will not be able to sit flush with the bottom tier.
Repeat for all 4 straws. Make sure they are all flush with the cake.
Now spread a layer of buttercream over the straws to hide them. This will also allow the top tier of the cake to stick to the bottom tier.
Stacking the top tier
Now for the fun part. Oh did I say fun? I meant terrifying haha. YES this part is scary but you can do it!
Time to get that top tier on top of the bottom tier. Here are some tips before you get started:
- If the buttercream is hardened, it will show less fingerprints if you mess up.
- If its fresh buttercream and hasn’t hardened yet, put it in the freezer for 10 minutes before you stack.
- Know that if you mess up there are always ways to fix something!
Ok lets do this!
Using your offset spatula, separate the 8″ cake board from the 6″ board that the cake is sitting on.
You are going to keep the 6″ cake board attached to the cake. With two hands, hold the cake underneath with just your finger tips. Bring it to the bottom tier and look overhead to where you want to place the cake.
Bring it as close as you can to the bottom tier without touching it and then drop it into place. If your straws are lined up correctly (which they should) then it will hold the weight of the cake!
Alternatively you can lean one side of the top tier on the bottom tier where the straws are, and then drop the other side on top, but I find that it can mess up the bottom tier of buttercream if it isn’t hardened that much.
If you choose to go the second route, then do it from the back so that if you mess up, it messes up the back of the cake.
THERE YOU GO YOU DID IT.
You stacked a two tier cake! Breathe a sigh of relief!!
What to do if you mess up
First of all it’s ok!! The most common place people mess up is the gap between the top and bottom tiers.
This is a super simple fix. You can pipe a border or design around the meeting point, or add another decoration like flowers, sprinkles, or cookie crumbs.
Also know that we are our worst critics, so something that may seem horrible to us (like a thumbprint) may not even register to someone who sees the cake for the first time.
How to decorate a two tier cake
There are so many ways you can decorate a cake! I love to decorate my cakes with fresh flowers. Learn how to do it safely in this post!
Other ways you can decorate a cake:
- Piping designs
- dessert sauces- drip them along the edges
- macarons- buy them in different sizes and place them on top.
- fresh fruit- make sure to keep it in the
Delivering a cake
If you are delivering a cake, then you need to make sure this cake is extra sturdy. One way to do this is by inserting a large dowel from the top of the second tier AFTER it is stacked.
This dowel should go through the top of the top tier, cut through the 6″ cake board and into the 8″ cake.
This will give the cake extra stability and make sure it wont topple over. Make sure you do this first before adding any decorations because you will have to hide the hole in the top tier.
I recommend using a wooden dowel for this this time and not a straw because the straws are not long enough. You can sharpen the dowel on the bottom to make sure it cuts through the cake board. Or you can buy cake boards that have a center hole for this very purpose.
WHEW this post was long!
Even though I don’t sell cakes for a living anymore, it’s nice to share my experience and info I learned along the way.
I hope it can help explain the things you need, and need to do, to stack a two tier cake!

How to Bake and Stack a Two Tier Cake
- 3 6" cake layers
- 3 8" cake layers
- 1 turn table
- 1 Offset spatula
- 1 6" cake board
- 2 8" cake board
- 1 10" cake board
- 5 bubble tea straws
- 1 bench scraper
- 1 food safe spray bottle
- 1 piping bag
- 1 round tip
For Vanilla Cake
- 8 eggs large
- 2 egg yolks
- 2 cups vegetable oil
- 3 cups granulated sugar
- 1 cup brown sugar
- 5 cups all purpose flour
- 4 tsp baking powder
- 2 tsp kosher salt
- 1 1/2 cups milk
- 4 tsp vanilla extract
Bake the cake
- Preheat your oven to 350° F and spray 3 8 inch round cake pans and 3 6" round cake pans with baking spray or line with parchment paper.
- In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl- combine eggs, yolk, oil, and sugars and mix well until combined.
- Combine the flour, baking soda and salt in a bowl and slowly add to the mixture on low speed.
- Slowly add in milk, and vanilla and continue mixing until a smooth batter forms, about 1-2 minutes.
- Evenly pour the batter into the pans and bake for 28-30 mins for the 6" and 35- 40 mins for the 8" The cake is done when a toothpick is inserted and comes out clean and when the edges are pulling away from the sides and are golden brown.
Fill and frost the 8" layer
- Using the cake leveler or a long serrated knife, level off the cakes so they have a flat top.
- Place a 10" cake board on the turntable, and a dab 1 tsp of buttercream in the middle and smooth it out. Place the 8" cake board on top and press it to stick to the 10" board. Smooth 1 tbsp buttercream on top of the 8" cake board, then place your first 8" cake layer on top.
- Using either a piping bag with a round tip or an offset spatula, place down 1/4 cup of buttercream on top of the cake, starting in the middle and smoothing to the outside. Leave 1/2" from the sides so it doesn't overflow over the cake. If using a piping bag, pipe a border around the cake and then fill the middle.
- Take the next 8" cake layer and turn it upside down so that the bottom is now the top. Place it on top of the filling. The cut side down should be on top of the buttercream. Repeat the process of filling the cake layer with buttercream and topping it with the last 8" cake layer.
- Using the offset spatula, and the turntable frost the entire cake (spinning as you go) from bottom to top for a light crumb coat. Place in the freezer for 15 minutes to seal in the crumbs.
Fill and frost the 6" layer
- Repeat the same steps as above for filling and frosting the 6" layer. Start by spreading 1/2 tbsp frosting over the 6" cake board and end by putting the cake in the freezer for 15 minutes. You should now have 1, 8" cake layer, and 1, 6" cake layer
Top coat frosting
- Using the offset spatula again, frost both of the entire cakes using more buttercream this time. When the cake is mostly covered with buttercream, switch to the bench scraper and smooth out the sides and tops of the cakes. Don't worry if it isn't perfect.
- Fill your water bottle with clean water and lightly spray one cake at a time on the turn table. Using the bench scraper again, smooth out any cracks. Repeat for the second cake.
- Using bubble tea straws or wooden dowels place 4 straws in a square shape in the center of the 8" cake making sure that they are being placed under where the 6" cake will be. Push each straw into the cake, then mark the straw where it hits flush with the cake and cut off the rest of the straw. The straws should be the same height as the 8" cake or a little under, just not higher.
- Spread a thin layer of buttercream over the straws.
- Using the offset spatula, lift the bottom of the 6" cake and hold it with 2 hands from the bottom. Center it above the 8"cake, get as close as you can and drop it into place on top of the 8" cake and straws.
- Continue decorating as you please! YOU DID IT!
