Hi sweet friends! I’m Morgan, a professional chef and a huge fan of Costco cakes. I’ve visited over 126 Costco stores, and I never leave without checking the bakery section. My love for desserts came from my dad, and now I live and breathe all things sweet. If there’s one thing I know deeply, it’s Costco cakes—from how they taste to how you can get the best one for your event.
Let me share everything important, helpful, and to-the-point, just like I would explain to you.
Why Costco Cakes Are Special
Consistent Taste, Affordable Price
- Every cake is soft, moist, and filled evenly
- Flavors are never too sweet and always balanced
- Feeds a crowd without breaking your budget
Perfect for Any Occasion
- Half-sheet cake feeds up to 48 people
- Great for birthdays, office parties, graduations, and baby showers
Made Fresh, In-House
- Baked and decorated daily at your local Costco warehouse
Friendly Reminder: You must have a valid Costco membership to buy any cake — even the ready-made ones. No card, no cake. So always bring your card with you!
Costco Custom Cake Prices (2025)
- 10-inch round cake: $16–$20
- Half-sheet cake: $25–$28
You won’t find a cake that big and that good for this price anywhere else.
Ready-Made Cakes (No Pre-Order Needed)
Available year-round in the bakery section:
- Tuxedo Chocolate Mousse Cake
- New York–Style Plain Cheesecake
- Chocolate Mousse Bar Cake
- Vanilla Cheesecake Mousse Cake (Round)
These are grab-and-go cakes, perfect for same-day parties or cravings.
When to Visit Costco for the Best Cake Picks (Trust Me on This!)
Morgan’s Tip (Yes, again!): For the best selection — especially if you’re after the Tuxedo Mousse Cake or Cheesecakes — get there before 11:00 AM, or even closer to opening time on weekends. These cakes go fast, and once they’re gone… they’re gone!
Limited-Time Seasonal Cakes
Only available for short periods—grab them while you can:
- Pumpkin Cheesecake (October–November)
- Pumpkin Pie (September–November)
- Carrot Bar Cake (March–April)
- Strawberry Shortcake Bar (May–July)
- Peaches & Cream Bar Cake (June–August)
- Red Velvet Bar Cake (February)
- Tres Leches Cake (varies by location)
- Yule Log Cake (December)
Pro Tip: Visit before 11:00 AM—many cakes sell out by the afternoon.
My Personal Favorites
- Chocolate Half-Sheet with Mousse – rich, reliable, crowd-pleaser
- Strawberry Shortcake – soft, fresh, summery
- Fruit Cake (seasonal) – light and flavorful for holidays
I love them all. Even if the frosting is different or the design is simple, the taste always makes me smile.
Quick Heads-Up:
This guide is all about regular Costco warehouses. If you’re heading to a Costco Business Center, just know their bakery section might be different — and they may not offer custom cakes at all. Best to call ahead before you make the trip, so you’re not disappointed.
How to Order a Custom Costco Cake
Step-by-Step Process
- Visit your local Costco – No online or phone orders
- Go to the bakery – Find the order form kiosk
- Fill out the form:
- Choose Size: 10-inch round or half-sheet
- Pick Flavor: White (with vanilla cheesecake mousse) or Chocolate (with chocolate mousse)
- Select Design: From preset options like balloons, roses, baby themes, graduation
- Add a personalized message
- Choose your pickup date & time
- Drop the form in the bakery box
- Pay at pickup – Bring your Costco membership card
Important Ordering Info
- Minimum 24 hours notice
- Best to order 48 hours ahead (especially for weekends/holidays)
- You can also order a week in advance if you’re planning ahead
Planning a Big Party?
If you need more than one custom cake (like two half-sheets or more), just chat with the bakery team when you drop off your order forms. They’re usually super helpful, and it’s good to confirm they can handle the size of your order for your pickup date.
What Makes Costco Cakes “Custom”
You Can Personalize:
- Cake size (round or half-sheet)
- Flavor and filling (white or chocolate)
- Frosting color accents
- Written message
- Preset design option
What You Can’t Customize:
- No licensed characters, photos, or unique designs
- No flavor mixing (e.g., chocolate cake with vanilla mousse)
Morgan’s Tip: Want more creative flair? Order a plain cake and decorate it yourself at home with sprinkles, toppers, or fruit.
Here’s a peek at the actual order form you’ll fill out at the bakery.
Take a good look before you go — I always recommend reading it at home so you know exactly what you want. Saves time, trust me!
Common Mistakes to Avoid
- Don’t wait until the day before—order 2–3 days early
- Avoid peak days near holidays—lines and delays are common
- Always double-check spelling on your order form
- Bring your own filled form to the store to save time
- No refunds unless Costco makes a mistake
Storage Tips for Freshness
- Keep cakes refrigerated
- Freeze leftovers in slices using foil and airtight bags (lasts up to 2 months)
- Chocolate frosting melts in hand—don’t hold too long before serving
How to Decorate a Costco Cake at Home
If you want a fancier look:
- Buy a plain cake
- Add your own frosting art, fruit, edible images, or party toppers
- Let kids decorate it for a fun birthday activity
