How to Order a Costco Cake and Get It Right the First Time

Costco’s big, affordable cakes are a lifesaver for birthdays, office parties, or any excuse to celebrate. But the process can feel a little fuzzy if you’ve never done it before. This guide breaks down exactly what you need to know—availability, ordering steps, pickup tricks, and delivery options—so you can walk out with a perfect cake without a hitch.

Is the Costco Sheet Cake Still Available?

Short answer: Yes, most locations still bake sheet cakes, but the selection changes by region and season. If you walk into the bakery, you’ll usually see a display of vanilla, chocolate, and red‑velvet sheet cakes, plus a few seasonal flavors like pumpkin or peppermint around holidays. Some stores have switched to a “pre‑order only” system for larger sizes to keep waste low, so it’s worth calling ahead.

The bakery team can also customize frosting colors and add simple decorations—think “Happy Birthday” writing or a few candy sprinkles. For more elaborate designs, you’ll need to place an order at least 48 hours in advance. Keep a pen handy and note the exact date you need the cake; Costco is strict about same‑day changes.

How to Order and Pick Up Your Cake

Here’s the step‑by‑step routine that works at almost every Costco:

• Call the bakery. Use the store’s main phone number, ask to speak with the bakery manager, and tell them the cake size (8‑inch, 10‑inch, or full‑sheet), flavor, and any frosting color.
• Give a clear date and time. They’ll lock in a pickup window—usually a morning slot for same‑day orders and an afternoon slot for pre‑orders.
• Confirm price. A basic sheet cake runs about $15‑$20, plus $5‑$7 for special frosting. Full‑sheet cakes can be $30‑$40 depending on size and decoration.
• Write down the order number. It’s a quick way to avoid mix‑ups when you arrive.
• Pick up at the bakery counter. Bring a photo ID; some locations ask for the card used for the membership. The staff will double‑check the order number and hand you the cake on a sturdy tray.

If you can’t make it to the store, ask if they offer delivery. Not every Costco ships cakes, but many in larger metros partner with third‑party couriers for a modest $10‑$15 fee. Delivery is usually limited to the same zip code or a 10‑mile radius, and you’ll need to give a clear address and a phone number for the driver.

Tip: Arrive a few minutes early for pickup. The bakery often finishes a batch right before the scheduled window, so being on time helps you avoid a wait.

Whether you’re ordering a simple vanilla sheet for a kid’s party or a chocolate masterpiece for a corporate event, the key is clear communication. Call, confirm the details, and show up on time. In a few minutes you’ll have a big, tasty cake that won’t break the bank.

Got a question about a specific flavor or a last‑minute change? The bakery staff are usually happy to help as long as you give them enough notice. So the next time you need a crowd‑pleasing cake, you know exactly how to order a Costco cake without any guesswork.
