How To Order Costco Cakes – Prices, All Designs, Pro Tips (2024)

Do you need a cake for a birthday party or large gathering? Costco sells a wide variety of custom cakes and even premade cakes!The Costco bakery offers a few different cake options, including round cakes and sheet cakes, of course, at an amazing Costco price.

If you need a high quality and tasty cake for your next party or event, don’t overlook the cakes from Costco’s bakery. They are easy to order, delicious, and will save you money.

In this guide, I cover all the Costco cake options, including the custom cakes and some of their decorated premade cakes. I provide the pricing for all of the cakes that Costco sells, including the round cakes and the sheet cakes.

I also walk you through the entire Costco custom cake ordering process and provide all pertinent information along with pro tips for designing your perfect cake. You’ll learn everything there is to know about ordering, customizing, and enjoying special occasion cakes from the Costco bakery.

Costco sells a variety of different cakes, but we’ll start with the two custom cake options: the round cake and sheet cake.

You can order both cakes from the “Mystery Cake Box” (we’ll talk more about this later) and you can customize the cakes with simple text or images.

A single serving of Costco’s sheet cake is on the smaller side for most people. Your guests may want more than one piece at your party.

With that in mind, it’s smart to buy servings for more than just the number of attendees. Stock up so there are seconds to go around.

Costco’s sheet cakes measure in at 12″ x 16″ (192 square inches) and feed about 48 guests. It’s worth noting this is technically a half-sheet cake as full-sheet cakes are typically 18″ x 26″ (468 square inches).

At 192 total square inches and 48 servings, each slice of Costco sheet cake works out to around 4 square inches, or a 2″ x 2″ piece.

Like almost everything else in the world, Costco has raised prices on their cakes. The current price for the 10” round cake is $15.99, up from $12.99 in 2022, and the sheet cake sells for $24.99, up from $19.99.

While price increases are always unfortunate, Costco’s cake stills are very fairly priced and offer some amazing value.

Sam’s Club sells their 10” round cake for $16.98, or about $1 more than Costco’s round cake price. Sam’s Club’s half sheet cakes sell for $18.98, which is about $6 cheaper than the Costco sheet cake price.

So it looks like Sam’s Club may be the best option if you are solely shopping on price.

Compared to regular grocery stores, Costco cakes are a steal. For example, Publix sells an 8” round cake for $20.99 and a half-sheet cake for $45.99.

These prices are typical of your standard grocery store and pale in comparison to Costco’s cake prices. You will pay nearly double for a cake that may or may not even be of the same quality tier as Costco’s cake.

Costco is an absolutely fantastic company, but their custom cake order system has fallen behind the times.

All orders Custom Costco cake orders must be placed at the in-store cake order kiosk using paper forms. Just like ordering aCostco party platter, there are no online or app ordering options available.

• Cake Size: 10” Round Cake or Half Sheet Cake
• Cake Flavor: White Cake (White Icing Fill With Vanilla Cheesecake Mousse) or Chocolate Cake (Chocolate Icing filled with Chocolate Mousse)
• Desired Cake Design: Select from one of the pre-created template designs. You can also leave this field blank. (Remember cake design choices will vary by season)
• Writing on Cake: Fill in with desired text on cake and select your desired color
• Member Information: Fill in your member information, including your selected pick-up date and pick-up time.

You will also notice a calendar on the cake order kiosk with all the days that Costco is closed during the year. The holidays that Costco is closed for are the following:

• New Year’s Day
• Easter
• Memorial Day
• Independence Day
• Labor Day
• Thanksgiving
• Christmas

Costco sells holiday cakes and custom designs for many occasions. However, if it is one of the above listed holidays, they are closed on the actual holiday day.

So you’ll need to pick up your special order holiday cake at least one day before the holiday.

Don’t expect a confirmation or even acknowledgement of your custom Costco cake order. And it may not the best system, but you will have to trust that your cake will be there on pick up day.

Head to Costco’s bakery and find the special order cake rack near the cake ordering kiosk. This rack holds all the custom cakes for the day, with each one attached to its order sheet. Search through the cake rack until you find your custom cake.

In the late afternoons or evenings, once most cakes have been picked up for the day, Costco bakery staff will often return any remaining cakes to the fridge in the bakery department. If you’re picking up a cake late in the day, you may need to ask a bakery employee for assistance in retrieving your cake from the fridge.

If you are picking up your cake order on a slower day (usually weekdays), Costco may not use the special cake rack. In that case, you’ll need to get the attention of one of the bakery employees and let them know you’re there to pick up your custom cake order.

Costco’s trio of roses cake is a favorite for special celebrations. Three glorious roses top this elegant cake, available in classic all-white for bridal events, passionate red for Valentine’s Day, or any customized color to match your theme.

The rose trio cake is a timeless choice for momentous occasions like birthdays, anniversaries, graduations, or any type of special event.

Costco’s scored cake design features smaller roses arranged throughout the cake. The round cake includes 16 multi-colored roses while the sheet cake has 48 roses total.

The useful scored design marks out perfect slices, making cutting and serving the cake much easier during a party. You can also request specific rose colors when ordering a custom Costco cake.

Celebrate birthdays in style with Costco’s colorful balloon cake designs. The 10-inch round cake features 3 festive balloons, while the sheet cake is topped with 5 balloons. The balloons come in various bright hues like red, blue, green, and orange or can be customized for the special birthday boy or girl.

These cakes are ideal for kids’ birthdays (or even adult birthdays), milestone birthdays, or any fun celebration.

You cannot go wrong with Costco’s candle design! The colorful candles and the ring of rainbow sprinkles around the border are perfect for making the birthday truly special.

The default colors of the candle are blue, green, red, and purple, but once again, the design can be customized to your liking.

Costco’s rainbow cake features a vibrant six-color rainbow arching across white frosting clouds. The rainbow uses red, orange, yellow, green, blue and purple shades, and the sheet cake version also includes a smiling sun design.

Costco leaves plenty of blank space underneath the rainbow for special customizable messaging.

My favorite of Costco’s cake designs and maybe one of their most unique options, The Costco Bear features a light brown teddy bear surrounded by colorful sprinkles around the outside edge. The cake design is fun, playful, and perfect for guests of all ages.

If you really like the bear cake design, get the life-size version to go with it. Only$399.99.

Costco has the perfect graduation cake design for new grads. The smaller round cake is decorated with a graduation cap and graduation year. The larger sheet cake option includes the graduation cap as well as balloons.

The best part is Costco can customize the colors to match your graduate’s school colors. Just write down the specific colors you want on the custom cake order form, and they will get it done!

Celebrate the 4th of July, Veterans Day, Memorial Day, or Flag Day with Costco’s USA flag cake design. This seasonal patriotic Costco cake is one of my favorites and, in my opinion, one of the most beautiful.

The sheet cake version has a blue border and also says God Bless America. You love to see the patriotism!

The Christmas cake design is decorated with a traditional Christmas wreath and a big red bow. The words Merry Christmas are also written on the cake.

The red and green design is festive and an easy option for celebrating the Christmas season.

Yes and No, Costco doesn’t usually honor requests, and they don’t even have a spot on the form to put any special request asides from the text. But the Costco bakery staff is reasonable and will accommodate minor and straightforward requests.

I’ve seen people who have successfully requested slight color or design changes. For instance, you could select the Happy Birthday Cake design and order all purple balloons, but don’t expect them to make custom designs or elaborate art on your cake.

Costco’s archaic special cake order form has gone viral recently when one Twitter user aptly named it the Costco “Mysterious Box”.

Lucy Huber tweeted, “Ordered a cake from Costco and their system is from the 1800s, you write what you want on a piece of paper & put it in a box then nobody follows up and you just show up and hope they made it? I tried to call to confirm & they were like “if you put it in the box, it will be there””

Need a cake ASAP? You might be in luck. Costco’s bakery sells pre-made 10” round cakes in their bakery for the general Costco public to buy. The pre-made Costco cakes are located in the bakery in the same area as some of the fancier cakes.

These are the same cakes you would get if you ordered the cake from the “mystery box,” just without the custom decorations or text.

Costco usually has premade round cakes available, but there’s no guarantee. They could sell out at any time, or not even make them for that day. And I rarely see premade sheet cakes there.

So if you know you need a cake, your best bet is to order through the “cake box” system. That’s the only way to guarantee you’ll get one from Costco.

Most premade cakes at Costco are either blank or have basic birthday designs. You’ll often see a generic “Happy Birthday” message with some candles or random colored balloons.

These cakes aren’t customized, but they’re a great last minute option if you need a birthday cake or even just a plain cake on short notice.

The cake size you select depends on your headcount. Costco offers two options: the 10-inch round (feeds 16) and the half sheet (feeds 48).

Keep in mind the suggested servings are based on petite slices. You’ll likely need more than 16 slices to satisfy 16 guests sufficiently. Running out of cake would be a big time party foul, always try to have extra

When deciding which of Costco’s cake to purchase, account for your guest count and consider sizing up if you want leftovers or just peace of mind. It is always better to have excess cake than run short! The Costco Bakery staff can also provide sizing guidance if you’re unsure.

If debating between the round and sheet cakes, I’d suggest opting for the sheet cake. It may cost $10 extra, but springing for the larger sheet cake ensures every guest can get a generous portion without worrying about running out.

Costco also has themed premade cakes for holidays like Christmas, New Year’s, Valentine’s Day, Memorial Day, Father’s Day, Mother’s Day, and more.

These cakes have designs fitting the occasion and can be grabbed right off the premade shelf.

Costco doesn’t specifically sell wedding cakes, but that hasn’t stopped countless members from using a Costco cake at theirreception.

The current wedding trend seems to be for the bridal party to have a specific more elegant (non-Costco) cake to cut and eat for themselves while the guests are served the basic Costco sheet cake.

• Cut up the remaining cake into slices
• Double wrap the cake slices individually in plastic wrap.
• Optionally wrap in a layer of foil for extra protection.
• Place the wrapped Costco cake into ziplock freezer bags.

Always slice the cake first, so when it comes time to enjoy it, you can just pick out the one or two slices of cake that you need.

I wasn’t going to include nutrition facts here since I have a whole page dedicated toCostco bakery calories, including their cakes.

But I know some folks may want that info handy at the party, in case any guests are watching what they eat, even though most of us don’t care about calories when taking down some cake!

One serving of Costco’s chocolate round cake is 4 ounces or 1/16th of a cake. Each serving contains 390 calories coming from 18 grams of fat, 57 grams of carbohydrates (45 grams of sugar) and 4 grams of protein.

The full nutritional label for Costco’s 10” chocolate round cake is below:

The 440 calories of Costco’s white round cake are made up of 21 grams of fat, 59 grams of carbohydrates (46 grams of sugar), and 3 grams of protein.

A serving of Costco’s sheet cake is 1/48th of the entire cake or 90 grams (just a little over 3 ounces). The calorie count for the Costco chocolate sheet cake is very similar to the chocolate round cake.

Each 90-gram serving of Costco chocolate sheet cake has 330 calories, 17 grams of fat, 42 grams of carbohydrates, and 3 grams of protein. The full nutritional label is as follows:

• Costco cakes are very sweet, rich, and decadent tasting. The cake itself is moist, soft, and spongy. The frosting is smooth, creamy, and buttery.
• The Costco vanilla cake with vanilla buttercream frosting and cheesecake mousse filling seems to be a favorite combination. The cheesecake mousse filling helps cut the sweetness and provides a nice tangy, creamy element.
• The Costco chocolate cake with chocolate frosting and chocolate mousse filling is also well liked. It’s an intense chocolate overload.
• Some find the frosting too sweet on its own but enjoy it combined with the cake and filling. Others feel it’s just right and complements the richness of the filling.
• The cakes are described as tasting similar to high-end, gourmet versions. Way better than typical grocery store sheet cakes. They taste homemade and fresh, not like chemicals.
• Overall, most agree the cakes from Costco taste fantastic, are moist, and have excellent frosting. They are sweet, as expected for American-style cakes, but the quality of ingredients comes through in the delicious taste. An excellent value purchase.
