Planning a wedding is basically a full-time job where you also happen to pay everyone else to do things. It’s exhausting. Somewhere between the $5,000 venue deposit and the $200-a-head catering bill, most people reach a breaking point where they just want things to be easy. And cheap. That is usually when someone whispers those four magic words: "Does Costco do wedding cakes?" It sounds like a fever dream of the budget-conscious. If they can sell a massive rotisserie chicken for five bucks, surely they can handle a three-tier vanilla bean masterpiece, right?
Well, sorta.
The short answer is no, not in the way you’re probably thinking. If you walk into a Costco expecting to flip through a thick binder of fondant lace patterns and Swarovski-studded tiers, you’re going to be disappointed. They don't do custom multi-tier wedding cakes. They just don't. But—and this is a big "but"—thousands of couples use Costco for their wedding dessert every single year. It’s a bit of a cult-favorite wedding hack that relies on a mix of their legendary sheet cakes and some clever DIY spirit. Honestly, it’s one of the best ways to save a literal thousand dollars on your reception without your guests ever knowing.

The Reality of the Costco Bakery Counter
Let's look at the facts. Costco's bakery is a high-volume machine. They are incredibly good at what they do, which is producing massive amounts of high-quality baked goods for a low price. They aren't an artisanal boutique. Because of this, their "wedding" options are limited to what fits their production line.
Until very recently, you could order a specific "Special Occasion" sheet cake that featured a simple, elegant rose design or a cross, which many people used as a base for wedding cakes. These are half-sheet cakes. They serve about 48 people. They cost roughly $25. Compare that to a traditional bakery where a wedding cake starts at $6 per slice, and you start to see why people are obsessed with making this work.
However, Costco recently made some changes. They discontinued the 10-inch round cakes that were once the staple of the "stacked" DIY wedding cake trend. Now, you’re primarily looking at the half-sheet cake. It’s a rectangle. It’s 12 inches by 16 inches. It’s filled with that iconic mousse and topped with buttercream. It tastes exactly like childhood and suburban birthday parties, which is to say, it’s delicious but not exactly "Black Tie Optional" in its raw form.
Why the "Custom" Request Usually Fails
If you try to call your local warehouse and ask for a custom flavor or a specific color of frosting to match your bridesmaids' dresses, the answer will be a polite "no." The decorators at Costco have a set list of designs they are allowed to do. They use specific templates. They have specific bags of pre-mixed frosting colors.
They won't do:
- Fondant
- Tiered stacking
- Custom color matching
- Intricate sugar flowers
- Fruit fillings they don't already stock
It’s a trade-off. You give up the customization for the fact that you’re feeding 150 people for less than the cost of a pair of wedding shoes. It’s about volume and value. If you want a cake that looks like a piece of modern art, you’ll need to go elsewhere. But if you want a cake that people actually finish eating, Costco is a heavy hitter.
The Famous Costco Wedding Cake Hack
Since Costco doesn't sell a tiered cake, how do people use them for weddings? It’s all about the "Cutting Cake" vs. "Sheet Cake" strategy. This is the oldest trick in the wedding planner's book.
Basically, you buy a tiny, beautiful, expensive six-inch cake from a high-end local bakery. This is the one you put on the pretty stand. This is the one you cut for the photos while everyone "oohs" and "aahs." Then, in the back kitchen, the catering staff is slicing up several Costco half-sheet cakes to serve to the guests. Once it's on a plate with a little drizzle of raspberry coulis or a fresh strawberry, no one is checking the box it came from. They’re just happy it’s not dry.
Some people go even further. I’ve seen couples buy three or four Costco sheet cakes, scrape off the "Happy Birthday" or the simple roses, and re-frost them. Or, they buy the plain white cakes and deck them out in massive amounts of fresh flowers. Flowers cover a multitude of sins. If you jam enough eucalyptus and peonies onto a $25 cake, it suddenly looks like it cost $200.
The Round Cake Dilemma
For a while, the 10-inch round was the holy grail. You could buy three, stack them yourself with some plastic dowels from a craft store, and boom—wedding cake. Since those are harder to find now (availability varies wildly by region and season), many couples are turning to the Costco cheesecake.
The 9-inch Kirkland Signature Cheesecake is a beast. It’s heavy, it’s creamy, and it has a plain top. Stack two of those with a layer of cardboard and some supports, add some fresh berries, and you have a "naked" wedding cake that tastes better than almost any traditional white cake you’ve ever had at a wedding.
What You Need to Know Before Ordering
You can't order these online for delivery. You just can't. You have to go into the warehouse, find the little kiosk by the bakery, and fill out a paper form. It’s very old-school. It’s analog.
You need to give them at least 48 hours' notice. During wedding season or around graduation time in May and June, give them more. A week is safer. You also have to pick it up yourself. Costco does not have a delivery van. If you’re the bride or groom, do not do this yourself on the morning of the wedding. Assign this to the "reliable cousin" or a bridesmaid who has a flat trunk space and a working air conditioner. These cakes are heavy, and the buttercream will melt if you look at it too hard in the July heat.
Pricing Breakdown
Let’s talk numbers because that’s why we’re here.
- Costco Half-Sheet Cake: ~$24.99 (Serves 48)
- Average Custom Wedding Cake: ~$500 - $1,000 (Serves 100)
- The "Costco Math": Three sheet cakes will feed 144 people for about $75.
Even if you spend $50 on fresh flowers and $30 on a fancy cake topper, you are still under $200 for the entire wedding dessert. That leaves a lot of room in the budget for an open bar or a better photographer.
The Taste Factor: Is It Actually Good?
We have to be honest here. Wedding cake is notoriously hit or miss. Often, you’re paying for the structural integrity required to hold up five tiers of cake, which usually means the sponge is a bit dense and the fondant tastes like sweet play-dough.
Costco cake is different. It’s a standard sponge, but the "mousse" filling—usually a vanilla cheesecake-style mousse—is genuinely light and flavorful. It’s a crowd-pleaser. It’s safe. It’s the "Greatest Hits" of cake. While it won't win any awards for innovation, you will rarely find a guest who complains about being served a slice of Kirkland’s finest.
Expert Tips for a Costco Wedding Cake
If you’re committed to the Costco route, there are ways to elevate the experience so it doesn't feel like a last-minute grocery run.
- The Display Matters. Don't serve it from the cardboard box. Get it out of the box, put it on a marble slab or a silver pedestal.
- Deconstruct It. If you don't want to deal with the sheet cake shape, use a circular biscuit cutter to cut rounds out of the sheet cake. Place each round on a plate, top with a single raspberry and a mint leaf. It looks like a high-end plated dessert from a French bistro.
- Scrape and Smooth. If the piping on the edges is too "supermarket" for you, take a flat palette knife and some extra white frosting and smooth out the sides. It creates that rustic, semi-naked look that is still very much in style.
- Berries are Your Friend. A pile of fresh, glazed strawberries or blackberries on top of a plain white cake screams "summer wedding" and covers up any imperfections in the frosting.
Potential Pitfalls
It’s not all sunshine and savings. There are risks. The biggest one is transportation. These cakes are not "structured" for travel. One sharp turn or a sudden brake and your cake is now a "deconstructed" mess against the side of the box.
Also, consider your venue. Some venues have a "cake cutting fee." This is a sneaky charge where they bill you $1.50 to $3.00 per person just to slice the cake and put it on a plate. If your venue does this, the savings of a Costco cake might be eaten up by the fee. Always check your contract. If the fee is high, it might be worth it to just get the fancy cake from their preferred vendor.
Final Verdict: Should You Do It?
Costco does not "do" wedding cakes in the traditional, bespoke sense. They provide the raw materials for a brilliant wedding hack.
If you are a "DIY bride" or you’re working with a tight budget, it’s a no-brainer. It is the most cost-effective way to feed a crowd without sacrificing taste. However, if you want a specific aesthetic, a multi-tiered tower, or a stress-free delivery experience, you should probably hire a professional baker.
There is no shame in the Costco game. Some of the most beautiful, high-budget weddings I’ve seen used Costco sheet cakes tucked away in the kitchen. It’s about being smart with your money. Why spend $800 on flour and sugar when you can spend $75 and put the rest toward your honeymoon?
Actionable Steps for the Budget Couple:
- Visit your local warehouse: Check the bakery kiosk to see exactly which designs are currently available. Design options can change seasonally.
- Do a test run: Buy a sheet cake for a smaller event—like a shower or a birthday—to ensure you actually like the flavor and texture before committing for the big day.
- Coordinate with your florist: Ask for a few extra stems of your wedding flowers specifically for cake decoration.
- Measure your fridge: Ensure you have enough cold storage space at the venue or at home, as these cakes are large and contain dairy-based fillings that must stay chilled.
- Confirm the cutting fee: Call your venue coordinator to ask if they charge for outside cakes and if that charge applies to sheet cakes.
