How to Stack a Tiered Cake

Cake is soft, and a stack of several layer cakes will sink and crack under its own weight unless something carries the load. In a tiered cake, each tier sits on its own board, and dowels pushed into the tier below transfer that weight straight down to the base.

This guide covers the materials, how to measure and place the supports, how to stack and center each tier, and how to prepare the cake for the trip to the table or venue. It applies to buttercream and fondant cakes made from firm layer cakes; very light sponges or mousse cakes need more structure than is described here.

Materials

Gather cardboard cake rounds the same size as each tier, a thick base board or drum 5 to 10 cm (2 to 4 inches) wider than the bottom tier, and dowels. Wide plastic dowels or bubble tea straws are easy to cut and hold a lot of weight; wooden dowels are stronger and work for heavy cakes and center dowels.

You will also need a ruler, a pencil or edible marker, sharp scissors or pruning shears for cutting dowels, and a large offset spatula for lifting tiers.

Preparing each tier

Build and frost each tier on its own board. The board should be the same size as the cake or very slightly smaller so it disappears behind the frosting. Chill the frosted tiers until firm, at least an hour, or longer for large tiers.

Common combinations are 15 cm on 20 cm (6 on 8 inches) for a two-tier cake, and 15, 20 and 25 cm (6, 8 and 10 inches) for three tiers. Tiers 5 cm (2 inches) narrower than the one below leave a ledge of about 2.5 cm (1 inch) all around, which looks balanced and leaves room for borders.

Placing and cutting dowels

Center an empty cake board the size of the next tier on top of the lower tier and trace lightly around it. Remove the board. Push one dowel straight down to the bottom board inside the traced circle, about 2.5 cm in from the line, mark it level with the top of the frosting, pull it out and cut it at the mark.

Cut the remaining dowels to the same length so the upper tier will sit flat. Insert them in an evenly spaced ring inside the traced circle. Four dowels usually suit a 15 cm (6 inch) top tier, five or six a 20 cm (8 inch) tier, and more for heavier or larger tiers.

• Keep dowels perfectly vertical; angled dowels carry less weight
• If dowels sit slightly above the frosting, the board will rest on them and not compress the cake
• Add one dowel in the center for tiers 25 cm (10 inches) and wider

Stacking

Slide a large offset spatula under the chilled upper tier and lift it with one hand under the board. Hold it over the traced circle, lower one edge first and slide the spatula out as you set it down. Check from several sides that it is centered and level.

Repeat for each tier. Pipe a border around the base of each tier to hide the seam and any small marks from the spatula. Chill the finished cake again before moving it.

Center dowel for transport

A stacked cake can shift if the car brakes or turns. For travel, sharpen one end of a long wooden dowel, slightly shorter than the cake's total height, and push it down through the center of all the tiers and boards, tapping it gently into the base board. Fill the hole at the top with a decoration or a dab of frosting.

Even with a center dowel, a tall cake is safest transported in tiers and stacked at the venue. Carry cakes on a flat, level surface, such as a non-slip mat on the floor of the car, never on a seat.

Serving a tiered cake

Remove the tiers from the top down before cutting. Lift each tier on its board with a spatula, pull out the dowels from the tier below and then slice it as a regular cake. Tell anyone else cutting the cake that it contains non-edible supports.

Cakes with perishable fillings or frostings such as whipped cream, cream cheese or custard need to stay refrigerated until shortly before serving and should not sit out more than 2 hours.

Common questions

Can I use drinking straws instead of dowels?

Wide plastic straws, such as bubble tea straws, are surprisingly strong for small tiers. Thin drinking straws bend and are not recommended. For heavy or tall cakes, use proper plastic or wooden dowels.

Do I need dowels for a two-tier cake?

Yes. Even a small 15 cm tier on top will slowly sink into the cake below, causing bulges and cracks. A few dowels prevent that.

How far ahead can I stack a cake?

Buttercream cakes can usually be stacked the day before and refrigerated. Allow space in the fridge for the full height, and keep it away from strong odors.
