Costco Wedding Cake Prices: 2026 Sizes and Ordering
If you are searching for costco wedding cake prices, plan on about $18.99 for a U.S. half-sheet custom cake that serves up to 48 people, though local prices and availability can change. Costco’s bakery gives you a budget-friendly base with two familiar flavor choices, and you can add a wedding look with flowers, a topper, or a cake stand.
Costco does not produce a fully custom, multi-tier wedding cake through its regular bakery service. You choose from the available cake sizes, flavors, messages, and standard designs, then handle any extra styling through your florist, venue, or decorator.
A few practical choices help you control portions, pickup timing, and the final presentation. Check your local Costco bakery or app before ordering, since warehouse options and prices vary.
What Will You Pay Per Guest?
A Costco half-sheet cake costs about $18.99 and serves up to 48 people, which works out to roughly 40 cents per serving before tax and any added décor. Local warehouse prices can differ, so confirm the current amount when you place the order.
That price covers the cake, filling, frosting, and a standard bakery design. Your full wedding dessert budget also includes a display stand, fresh flowers, a topper, cutting supplies, delivery, or help from a decorator.
Half-Sheet Cake Price and Cost Per Serving
A Costco sheet cake is the most common choice for a large reception. The standard half-sheet size serves up to 48 guests when cut into small reception portions.
At about $18.99, one cake provides a low per-serving cost. Two cakes serve close to 96 people, while four cakes provide enough cake for roughly 192 guests. Ask the bakery about its current serving guidance if you want larger slices.
A half-sheet cake is rectangular and arrives ready to serve. You can order multiple cakes in the same flavor or split the order between white cake with vanilla cheesecake mousse and chocolate cake with chocolate mousse.
How Costco Compares With a Custom Wedding Cake
A custom wedding cake includes design work, tier construction, specialty fillings, delivery, and setup. Those services raise the price well beyond a Costco sheet cake, especially when you request sugar flowers, fondant details, hand-piped decoration, or several flavors.
Costco gives you a lower-cost base with less design flexibility. A local cake studio gives you more control over shape, color, texture, and display. If you want a formal tiered centerpiece with venue delivery, a custom wedding cake may justify its added cost.
If your priority is feeding a large guest list affordably, Costco cakes offer a practical route. For a wider look at wedding dessert budgets, see what price are wedding cakes.
Does a Costco Membership Affect the Total Cost?
A Costco membership gives you access to warehouse bakery purchases, including custom cake orders. The membership fee becomes part of your event budget if you are joining only for the cake.
You may still find value in membership if you plan to buy other wedding supplies, food, drinks, or desserts from Costco. Price the cake, membership, décor, and any extra shopping together before deciding.
Which Cake Size Fits Your Guest Count?
Choose a 10-inch round cake for about 16 servings or a half-sheet cake for up to 48 servings, then combine cakes when your guest list is larger. Your portion plan should account for children, smaller reception slices, and other desserts on the table.
Costco cake sizes suit practical serving plans more than elaborate tiered displays. Count the people who will eat cake, decide whether you want leftovers, and confirm the warehouse’s current size and serving information before submitting your order.
Costco Cake Sizes and Typical Servings
The standard U.S. options include:
| Cake size | Approximate servings | Best use |
|---|---|---|
| 10-inch round cake | 16 | Small celebration or cutting cake |
| Half-sheet cake | 48 | Main reception dessert |
The half-sheet cake gives you the most servings for the price. The round cake offers a more traditional shape for a small wedding or a display cake.
Ask your Costco bakery about available cakes and desserts because selection can vary by warehouse. The bakery’s order form or Costco app should show the current choices for your location.
How Many Sheet Cakes Should You Order?
Divide your expected cake servings by 48, then round up. For 50 guests, two half-sheet cakes give you a comfortable serving cushion. For 100 guests, three cakes provide about 144 servings, which leaves room for generous portions and seconds.
You can use one cake as a display piece and keep additional cakes in the kitchen for cutting. This approach lets you create a clean reception presentation while keeping the serving supply easy to manage.

Planning Portions When Cake Is Not the Only Dessert
Order fewer cake servings when your table includes cupcakes, cookies, brownies, cheesecake, or another substantial dessert. A half-sheet cake for every 48 guests works well when cake is the main sweet course.
If cake is one choice among several desserts, plan smaller portions and ask your caterer how many guests they expect to choose each item. Keep extra servings available for the couple, the wedding party, and guests who want seconds.
Which Flavors and Finishes Come Standard?
U.S. Costco custom cakes come with two main flavor combinations: white cake with vanilla cheesecake mousse or chocolate cake with chocolate mousse. Your frosting, message, and decoration choices come from the designs available at your local Costco bakery.
These choices keep ordering easy and prices low. Seasonal designs and small color adjustments depend on the warehouse and the bakery team handling your order.
White Cake With Vanilla Cheesecake Mousse
White cake with vanilla cheesecake mousse gives you a mild flavor that suits a broad guest list. The white interior and light-colored frosting also fit classic wedding palettes.
Choose this option when you want a traditional appearance or plan to add white flowers, greenery, pearls, or a light-colored topper. Ask whether your warehouse can adjust the writing or decoration color before placing the order.
Chocolate Cake With Chocolate Mousse
Chocolate cake with chocolate mousse creates a richer dessert with a clear cocoa flavor. It works well for couples who want a darker cake option or a second flavor beside the white cake.
For a large reception, ordering one flavor of each lets guests choose. Label the cake flavors on the dessert table so guests know what each slice contains.
Buttercream Frosting, Messages, and Simple Designs
Costco cakes use buttercream-style frosting for their standard finishes. Available designs can include flowers, balloons, seasonal themes, scored servings, or other bakery-approved patterns.
You can add a short message and request a writing color when the order form provides that option. Keep your request within the displayed design choices, and write the wedding date and pickup details clearly.
A topper or fresh flowers can add a formal look without requiring a custom cake structure.
Can a Costco Cake Look Wedding-Ready?
A wedding cake from Costco can look polished when you use a simple display cake, coordinated décor, and careful assembly. The finished style comes from how you present the cake, since the regular bakery menu focuses on standard shapes and decorations.
You can keep the Costco cake’s original frosting and improve the presentation with a clean stand, matching linens, and flowers that coordinate with your bouquet. Confirm food-safety details with your florist before placing flowers on or beside any cake.
Creating a Tiered Look With Sheet Cakes
Stacking sheet cakes requires support, a stable base, and careful cutting. A safer display plan uses one round cake or a decorated portion for the cake table while keeping full sheet cakes refrigerated until serving.
If you want a stacked design, ask an experienced cake decorator to handle the structure. Sheet cakes are rectangular and dense, so cutting them into layers or building a tall display needs proper supports and chilled handling.
You can also arrange two sheet cakes side by side on a large decorated board. Add piping or flowers around the edges to create a unified presentation without lifting heavy cake layers.
Using Flowers, Toppers, and Cake Stands Safely
Use food-safe barriers between fresh flowers and frosting. Your florist can prepare stems for cake placement, while a topper should be lightweight and balanced.
Choose a cake stand that supports the full weight and fits the cake board. Place the stand on a level table away from direct sun, heaters, and crowded serving areas.
Keep decorative pieces out of reach of children and remove non-edible items before cutting.
The Cake Bake Shop by Gwendolyn Rogers Option
Costco also sells select The Cake Bake Shop by Gwendolyn Rogers cakes through its online marketplace. The featured 8-inch cakes serve about 16 to 22 people, arrive frozen, and come in multiple flavors, with pricing reported around $160 per cake.
These cakes offer a more formal presentation than a warehouse sheet cake, though they still have a fixed design and flavor selection. Check the current listing, shipping window, serving estimate, and storage instructions before ordering for a wedding date.
How Do You Order and Transport It?
Place a Costco custom cake order at least three days before pickup through the Costco app when available, or use the bakery’s in-store paper order process. Ordering one week ahead gives you more time for a busy wedding season, holiday schedule, or order correction.
The Costco app requires you to sign in with a verified membership, and custom cake ordering appears under the Warehouse Ordering area of the Warehouse tab. Costco continues to accept paper orders in stores.
When to Submit a Bakery Order Form
Select the warehouse, pickup date, cake size, flavor, design, message, and writing color. Review every detail before submitting the form or placing the app order.
The app supports custom cake orders up to two weeks ahead and requires at least three days’ notice. Online orders allow up to five cakes with the same customization. Contact the warehouse for larger quantities or multiple designs.
For a wedding, place the order at least a week before the event when possible. Pick up the cake the day before if your venue has reliable refrigeration.
What to Confirm With Your Local Warehouse
Call or visit the Costco bakery to confirm:
- Current price and serving count
- Available cake sizes and flavors
- Design and writing-color choices
- Pickup timing
- Order limits for multiple cakes
- Holiday or seasonal closures
- Payment and modification procedures
Your confirmation email should show the warehouse, pickup instructions, estimated total, and steps for changes. Contact the selected warehouse when you need to modify or cancel an order.
Pickup, Refrigeration, and Reception-Day Transport
Bring a level vehicle surface and keep the cake boxes flat during transport. Use air conditioning in warm weather, drive smoothly, and avoid placing boxes in a hot trunk.
Move the cake into refrigeration as soon as you arrive. Keep each cake in its bakery box until setup, then transfer it to the prepared stand or serving table.
Ask your venue about refrigerator space, delivery access, setup time, and a safe cutting area.
When Should You Choose Another Wedding Dessert?
Choose a different dessert when you need a highly personalized design, venue delivery, professional setup, or a flavor beyond Costco’s standard menu. Costco works best for couples who value a low price and straightforward serving plan.
Your guest list, venue rules, and design goals should guide the choice. A mixed dessert table can also give you a wedding centerpiece plus several flavors without ordering a large custom cake.
When a Custom Bakery Is Worth the Added Cost
A custom bakery earns its higher price through design labor and event service. Choose one when you want a specific tier shape, hand-made sugar flowers, fondant detail, allergy-aware preparation, multiple fillings, or delivery and setup.
Ask for a written quote that separates cake servings, design work, delivery, stand rental, and cutting fees. You can compare that total with the cost of Costco cakes plus décor and transportation.
A local baker also gives you a point of contact for tastings, revisions, and venue coordination. Those services help when the cake plays a central role in your reception design.
Tuxedo Chocolate Mousse Cake and Cheesecakes
Costco’s tuxedo chocolate mousse cake offers a rich option for guests who enjoy chocolate mousse and layered textures. It works well on a dessert table beside a smaller cutting cake.
Cheesecakes add a creamy alternative for guests who prefer a denser dessert. Check the package size, serving count, refrigeration needs, and current warehouse availability before relying on either dessert for your full guest list.
Brownies and Other Supplemental Dessert Options
Brownies, cookies, fruit desserts, and assorted pastries help fill out a reception table. They also make it easier to offer a choice when your main cake has one or two flavors.
Use labeled platters and separate serving utensils for each item. Keep refrigerated desserts cold and place brownies or shelf-stable treats away from heat and direct sunlight. For more ideas, explore these wedding dessert ideas.
