Costco Cake Guide: Everything You Need to Know About Sheet Cakes

Thinking about a big, affordable cake for a birthday or office party? Costco’s bakery has long been a go‑to spot for giant sheet cakes that feed a crowd without breaking the bank. But the lineup changes, and many people wonder if you can still get one, how to order, and what to expect on price. This guide gives you straight‑forward answers and practical tips.

How to Order a Costco Sheet Cake

First, head to the bakery section of your local warehouse. Most stores keep a handful of pre‑made sheet cakes on shelf – usually chocolate, vanilla, and a seasonal flavor. If you want a custom design, ask the bakery staff about a special order. They’ll ask for:

• Size: Common sizes are 8‑inch (serves ~24) and 12‑inch (serves ~48). Some locations offer a 16‑inch option for larger groups.
• Flavor and frosting: Choose from chocolate, vanilla, red velvet, or seasonal options like pumpkin. Frosting is typically buttercream, but some stores can do fondant for an extra fee.
• Message: You can add a short message on the top. Keep it under 20 characters to avoid extra charges.

Place your order at least 48 hours ahead of time. Most Costco bakeries require a small deposit; you’ll pay the balance when you pick up the cake. Bring a photo of any design you want, or simply describe it – the staff are good at translating ideas into a clean, simple look.

Alternatives and Savings Tips

If your nearest Costco doesn’t carry sheet cakes, try a few workarounds. Some locations let you buy a regular round cake and ask for it to be cut into squares – it’s not a sheet, but you still get the bulk serving size. Another trick is to purchase a bulk box of cupcakes from the bakery; they’re often priced similarly and can be displayed like a cake.

To stretch your budget further, consider these ideas:

• Pick a basic flavor: Chocolate or vanilla are the cheapest. Add your own decorations at home – sprinkles, fresh fruit, or a simple drizzle of chocolate.
• Buy in bulk and freeze: Costco cakes freeze well. Order a large cake, slice it, and wrap portions for later events.
• Combine orders: If several coworkers need a cake for different birthdays, combine them into one larger sheet and share the cost.

Price ranges vary by region, but you can expect an 8‑inch chocolate sheet to run around $20‑$25, while a 12‑inch custom design can be $35‑$45. Keep an eye on seasonal promotions – Costco often offers “Buy One, Get One” deals on bakery items around holidays.

One common mistake is assuming every Costco has the same selection. Smaller warehouses may only carry a limited range, so call ahead and ask about availability before heading out. The staff usually reply within minutes and can even reserve a cake for you.

Finally, remember that the biggest selling point of a Costco cake is its size and price. If you need a fancy, tiered wedding cake, you’ll likely look elsewhere. But for birthdays, office celebrations, or simple gatherings, a Costco sheet cake delivers a reliable, tasty option with minimal hassle.

Bottom line: Yes, Costco still offers sheet cakes in most locations, you just need to know the ordering steps, plan ahead, and use a few smart tricks to keep costs low. With the right prep, your next party will have a big, delicious cake without the stress of an overpriced bakery.
