You've worked hard and the cake is finished – but now comes the part that can actually ruin it: getting it to the party. Three things go wrong on the way. The box turns out to be too short for the topper, the frosting gets smudged while the cake is lowered in, or a cold cake sweats inside a warm car and the box goes soft. All three are avoidable, and most of it comes down to choosing the box by the cake board and loading it from the back.
Choose the box by the board, not the cake
A decorated cake travels on a cake board, so the board is what has to fit. Our two tall boxes are 8 × 8 × 8 in and 10 × 10 × 8 in: pick the one whose footprint matches your board, and the board will sit snugly on the floor of the box so the cake cannot slide. The walls are 8 inches tall on both; the gable top adds a little headroom in the center, but plan for everything on the cake to stay under 8 inches, or add tall toppers when you arrive.
| Box | Suits | Board | Height available |
|---|---|---|---|
| 8 × 8 × 8 in | A 6-inch round or square cake, layered as tall as you like | Up to 8 in | 8 in walls |
| 10 × 10 × 8 in | An 8-inch cake, or a small two-tier that stays under 8 inches tall | Up to 10 in | 8 in walls |
A cake needs about an inch of air on each side so the frosting never touches the walls or the window. A 6-inch cake on an 8-inch board in the 8 × 8 box has exactly that; so does an 8-inch cake on a 10-inch board in the 10 × 10.
Load it from the back
Most cake boxes make you lower the cake in through the top, with your fingers next to the frosting and the cake tilting as it goes. Ours open at the back instead: the rear panel folds down flat, you slide the board in from behind, and the front window never gets touched. The box itself folds up in one piece with no tape or glue.
- Fold the box first, before the cake comes out of the fridge, and lock the gable top and handle. It takes under a minute once you have done one.
- Open the back panel so it lies flat on the counter, making a ramp level with the floor of the box.
- Slide the cake in on its board. Push on the board, never the cake, until it sits centered behind the window.
- Close the back and tuck the tabs. Check through the window that nothing is touching the walls.
Chill the cake, keep the box dry
Buttercream and ganache travel far better firm than soft, so chill the cake for half an hour before it goes in. The thing to avoid is moisture on the card: a cold cake in a warm, humid car sweats, and a wet box loses its stiffness. Keep the boxed cake cool and out of direct sun, run the air conditioning, and never set the box down on a wet counter or a damp floor. If the cake has to sit in the fridge inside its box, that is fine for a few hours; just keep it away from anything dripping.
Carrying and driving
The handle is there for the walk from the car to the door with a 6-inch cake. For a heavier 8-inch cake, or any distance, put a flat hand under the base as well; a box carried by the handle alone swings, and a swinging cake shifts on its board. In the car, the flattest surface is the floor of the passenger footwell or the trunk, not a seat, which slopes. A non-slip mat under the box stops it sliding in corners.
The boxes
Both are made of thick 500 gsm white card with a large clear window in the front, a one-piece fold that needs no tape, the back opening described above, and a handle. They ship and store flat, ten to a pack.

The short version: match the box to the cake board, keep decorations under 8 inches, slide the cake in from the back, chill it first, keep the card dry, and carry it with a hand underneath. The cake will arrive the way it left.
