When you need a sheet cake for a crowd, simplicity and reliability matter most. Whether you’re planning a birthday party, church event, school function, office celebration, or holiday gathering, a sheet cake is one of the easiest and most practical desserts you can make.
No stacking layers.
No complicated decorating.
No stress.
A sheet cake for a crowd bakes evenly, slices easily, travels well, and feeds a large group without extra effort. If you’re hosting and need a dessert that impresses while staying simple, this guide will help you choose the perfect sheet cake.
Why a Sheet Cake Is Perfect for Large Groups
Sheet cakes are ideal because they:
- Serve 20+ people easily
- Bake in one large pan
- Require minimal decorating
- Are easy to transport
- Store well
- Save time
Instead of baking multiple cakes, one large sheet cake for a crowd does the job beautifully.

What Size Sheet Cake Feeds a Crowd?
Here’s a quick breakdown:
- 9×13-inch pan → Serves 12–15 people
- Half-sheet pan (13×18 inches) → Serves 24–30 people
- Full-sheet pan (18×24 inches) → Serves 40–50+ people
For most home gatherings, a half-sheet pan is perfect.
If you’re hosting 25 guests, a half-sheet cake is your best choice.
