You’ve spent hours whisking, baking, and decorating the perfect cake. The last thing you want is for it to lose its freshness, smudge its buttercream, or topple over on the way to the celebration. This is where smart cake packaging comes in.
Whether you’re a home baker sending a birthday cake to a friend or a professional cake artist delivering to a client, packaging is just as important as the baking itself. It keeps your creation fresh, makes transport stress-free, and adds that extra wow-factor when the box is opened.
So, how do you pack a cake? The quick answer: measure your cake, pick a sturdy box slightly larger than its size, and secure it with a base board and minimal movement inside. For individual slices, use slice boxes or wrap them neatly to preserve presentation.
Let’s dive into the details: because getting the packaging right can make all the difference between a bakery-worthy reveal and a sticky disaster.
What Cake Size Should You Choose?
Before looking at packaging, think first about cake size. After all, the dimensions of your cake will dictate the type of box you’ll need. If you are using a cake board, you also have to add this measurement.
When bakers talk about cake portion sizes, they usually refer to how many people the cake will serve. A 6-inch cake might be perfect for an intimate dinner with a few friends, while a 10-inch cake could feed a crowd at a birthday party.
Here’s a quick guide to cake serving sizes:
-
6-inch round cake: Serves about 8–12 people
-
8-inch round cake: Serves about 15–20 people
-
10-inch round cake: Serves about 25–30 people
Of course, this depends on whether you’re cutting generous dessert slices or smaller coffee-style servings. A wedding cake, for example, is often served in slim slices so that more guests can enjoy a piece. A casual family celebration might call for thicker slices with extra icing.
If you’re unsure, try using a cake size chart or our handy Cake Calculator. Simply enter your cake dimensions and get an instant guide to ingredient requirements — making it much easier to plan ahead. This tool is particularly useful if you want to scale recipes up or down without the guesswork.
Choosing the Right Cake Packaging
Now that you’ve settled on your cake size, it’s time to choose the perfect box to protect it.
Choosing the Right Cake Box
The golden rule: your cake packaging should be sturdy, the right size, and easy to assemble. Pick a box that’s 1–2 inches larger than your cake in both width and height. For example:
-
6-inch cake: 8-inch box
-
8-inch cake: 10-inch box
-
10-inch cake: 12-inch box
Most cakes are between 4–6 inches tall, but when you add buttercream decorations, fondant layers, or toppers, the total height can increase quickly. To avoid squashing your design, make sure your box is at least 1–2 inches taller than the cake itself.
It’s also important to think about the cake board. A sturdy board underneath gives the cake stability and makes it much easier to lift in and out of the box. Match the board size to the box size for the most secure fit.
Types of Boxes
Not all cake boxes are created equal. Here are the most popular options:
-
White Boxes:
The classic choice. They’re clean, simple, and affordable. Perfect for everyday bakes, gifts, or personal use. They’re also stackable, making them practical if you’re baking multiple cakes for one event. -
White Boxes with Windows:
These give a sneak peek of the cake without needing to open the lid. Great for showcasing your design while keeping it protected. They’re ideal for cakes being sold in bakeries or markets where customers want to see what they’re buying. -
Clear Boxes:
If you’re aiming for a premium look (think wedding cakes or high-end events), a transparent box makes your cake the star of the show. These boxes add elegance while still providing support. They also photograph beautifully.
If you’re baking often, consider buying cake boxes in bulk. Not only does it save money, but you’ll also never find yourself scrambling for packaging at the last minute. We offer discounts on packs of 25, 50, or 100 boxes, which is a worthwhile investment if you’re running a small baking business.
Packaging for Cake Slices
Sometimes you’re not delivering a whole cake, but sharing it slice by slice. This is where thoughtful packaging really shines.
Individual Slice Boxes
Single-slice cake boxes are a great way to keep portions neat and professional-looking. They’re especially popular for weddings, birthday parties, or café takeaway options. Choose boxes that fit snugly around a slice without leaving too much empty space (which can cause the slice to slide around).
You can also get creative here — there are triangular slice boxes, square boxes, or even clear clamshell-style containers. Each option has its advantages: triangular boxes highlight the “slice” shape, while square boxes give a more modern, café-style presentation.
Wrapping Options
If you don’t have slice boxes on hand, wrapping each piece works well too:
-
Use parchment paper or wax paper to prevent sticking.
-
Wrap slices tightly in cling film for freshness, then place them in a small cardboard box or tin.
-
For extra polish, finish with a ribbon, sticker, or label. This makes even a simple slice look like a thoughtful gift.
Tips for Neat Slices
-
Chill before cutting: A chilled cake is much easier to slice cleanly without smudging frosting.
-
Use a hot knife: Dip your knife in hot water, wipe dry, then slice. This gives sharp edges and neat servings.
-
Line your box: Adding a piece of parchment or a doily prevents crumbs and buttercream from smearing inside the packaging.
If you’re handing out individually wrapped wedding cake slices as favours, wrap each one in parchment and then place it in a clear bag tied with ribbon. It’s practical, tidy, and leaves guests with a good taste in their mouth (literally).
By paying attention to how slices are packaged, you’re ensuring every piece looks as inviting as the first cut.
Conclusion
Packaging a cake is more than just popping it in a box. It’s about protecting your hard work, keeping it fresh, and presenting it beautifully. From choosing the right cake size to finding a box with the perfect dimensions, every step ensures your cake arrives safely and impresses on the big reveal.
Remember:
-
Measure your cake and pick a box that’s slightly larger.
-
Allow an extra inch or two in height so your decorations stay intact.
-
Choose between white, windowed, or clear boxes depending on the occasion.
-
For individual portions, use slice boxes or wrap neatly to keep servings fresh.
