Cake for 50 Guests: Size, Layers, and Simple Tips

Planning a cake for a crowd can feel overwhelming, but it doesn’t have to be. With a few quick calculations and smart choices, you can serve 50 happy guests without breaking the bank or stressing in the kitchen.

How big should the cake be?

The first step is figuring out the total cake weight you need. Most bakers recommend about 100–120 grams (3½‑4 oz) per person for a standard slice. Multiply that by 50 and you get roughly 5–6 kilograms (11‑13 lb) of cake.

Next, decide on the shape. A round cake is the easiest to cut evenly. A 12‑inch (30 cm) round cake provides about 30‑32 slices, so you’ll need a second tier. A popular combo is a 12‑inch bottom layer plus a 9‑inch top layer. Together they give you close to 60 slices, leaving a little wiggle room for seconds.

If you prefer a square cake, an 11‑inch (28 cm) square gives around 36 slices. Add an 8‑inch square on top and you’ll be right on target. Remember, the more surface area you have, the easier it is to decorate and the simpler the cutting.

Tips to keep costs down and flavours wow

1. Choose simple flavours. Classic vanilla or chocolate layers cost less than exotic herbs or fresh fruit fillings. You can still wow guests by adding a raspberry jam layer or a drizzle of caramel.

2. Make your own frosting. Store‑bought buttercream looks nice but a homemade cream cheese frosting uses fewer expensive ingredients and tastes fresher.

3. Limit decorations. A single ribbon, fresh flowers, or a dusting of cocoa powder can look elegant without the cost of elaborate sugar work.

4. Bake in advance. Most cakes keep well wrapped at room temperature for two days or in the fridge for up to a week. Baking early spreads the workload and avoids a last‑minute rush.

5. Consider a sheet cake. If you don’t need a towering design, a 9×13‑inch sheet cake can be cut into 50 pieces with a little trimming. It’s often cheaper because you buy one pan instead of multiple round tins.

When it comes to serving, use a gentle hand. A 1‑inch (2.5 cm) slice is a good standard. If you have a mix of kids and adults, you can cut slightly smaller pieces for the kids and a bit larger for the grown‑ups.

Finally, keep a backup plan. Have a simple store‑bought cake or cupcakes on hand just in case a slice falls short. It’s better to have a little extra than to run out.

With these calculations and tips, you’ll feel confident ordering or baking a cake that feeds 50 guests comfortably, looks great, and stays within budget. Happy baking and enjoy the celebration!
