15 Essential Costco Cake Tips to Keep in Mind Before Ordering the Dessert

Costco is a go-to destination for two primary reasons—purchasing food in bulk and securing incredible deals. Of course, there are added perks like free samples, vacation packages, and discounted gas. However, many members join specifically to cut down on their grocery expenses. A Costco membership unlocks access to lower prices on fresh and shelf-stable items such as meat, produce, coffee, and dairy, along with discounted gift cards, kitchen appliances, and paper goods. Additionally, the membership grants entry to Costco’s bakery, which offers seasonal pies, freshly baked bread, and a variety of desserts. True to Costco’s reputation, the prices are affordable, but the quality remains top-notch. With in-house bakers, the baked goods are both fresh and expertly crafted. While it’s tough to pick a favorite, Costco cakes stand out as a crowd-pleaser. The cakes are light and fluffy, complemented by smooth mousse fillings and buttercream frostings that are sweet without being overly rich. Since most Costco cakes aren’t available for online orders, here’s what you should know before visiting your local warehouse.

The Prices Are Unbelievably Affordable

Baking a cake from scratch or even using a boxed mix is no small feat. From precise measurements to preparing the perfect frosting, it’s a time-consuming and meticulous process. This is why professional bakers often charge premium prices, reflecting the expertise and effort required to create a culinary masterpiece.

However, not everyone is willing or able to pay premium bakery prices. For those seeking an affordable yet delicious cake, Costco comes to the rescue. Costco’s cakes are priced as follows:

• $15.99 for an 8-inch round cake
• $19.99 for a 10-inch round cake
• $24.99 for a half sheet cake
• $39.99 for a full sheet cake

The Sheet Cakes Are Perfect for Large Gatherings

Costco offers a variety of cakes, including round, sheet, and bar cakes, with flavors ranging from vanilla and chocolate to carrot and tuxedo. The classic sheet cakes are particularly popular, especially for events like birthday parties and large celebrations. These cakes are designed to be practical rather than overly decorative, focusing on feeding a crowd. A half-sheet cake can serve up to 48 people, while a full sheet cake can satisfy up to 96 guests.

Plan in Advance for Custom Cake Orders

If you need a customized cake quickly, Costco can accommodate your request as long as you place your order at least 48 hours in advance. While limited options are available online, most cakes, especially custom ones, require an in-person visit to the bakery. The ordering process is straightforward, allowing you to personalize the size, flavor, design, and message on the cake.

Sheet Cakes Are Limited to Two Flavors

While Costco offers many advantages for cake orders, there is one limitation: the flavor options. The prices are unbeatable, but the selection is narrow. If you’re considering a sheet cake, your choices are limited to white (vanilla) or chocolate:

• White Cake, featuring a vanilla cheesecake mousse filling and white buttercream frosting
• Chocolate Cake, filled with chocolate mousse and topped with chocolate buttercream frosting

Pre-Made Cakes Are Perfect for Last-Minute Events

If you’re expecting to find a large sheet cake ready to go at the Costco bakery, you might be let down. Costco doesn’t stock pre-made sheet cakes, so you’ll need to place your order at least two days ahead. However, that doesn’t mean you can’t walk into Costco and leave with a cake on the same day. The store offers a selection of ready-made round and bar cakes for spontaneous purchases. While these cakes aren’t customizable, many come decorated with festive elements like balloons, candles, and flowers, making them ideal for various celebrations.

A Wide Range of Design Options Are Available

Costco’s sheet cakes, designed to feed large groups, are perfect for all kinds of events, from birthdays to graduations, sports celebrations, and anniversaries. You can select from over two dozen designs, with additional seasonal options available. Classic designs include the American flag, balloons, and roses, but you can also choose from themes like graduation, princess, beach, or football cakes, among others.

Add a Personal Touch With Custom Writing

Adding a personalized message to a cake is a small but thoughtful detail. Since Costco offers limited customization options for sheet cakes, this feature is worth utilizing. Whether you include a name or a heartfelt message, there’s no additional cost for adding text to a custom cake.

Tiered Cakes Are Available for Order

While most Costco cakes aren’t available online, there are exceptions, and inventory may vary between online and in-store options. If you’re searching for a tiered cake, you’re in luck. Costco’s 2 Tier Cake, referred to as a “Special Occasion Cake,” is ideal for weddings and similar events. With the average wedding cake costing around $500, ordering from Costco can save you up to 40 percent. This cake serves approximately 24 guests, making it perfect for smaller weddings, baby showers, birthdays, or anniversaries. Since tiered cakes aren’t typically stocked in stores, this is a great option to explore online.

Store Cakes in the Refrigerator

Costco cakes, made with fresh buttercream, are perishable and should be refrigerated. While some have kept them at room temperature for a day or two, they are not shelf-stable and require refrigeration before your event. Make sure to clear space in your fridge if you plan to pick up a cake ahead of time. For outdoor events in warmer weather, use an insulated bag to keep the cake cool during transport.

Ask for a Scored Cake for Easy Slicing

Cutting a large sheet cake can be tricky, but Costco offers a solution. Simply request the bakery to score your cake, which involves marking it with buttercream lines to guide slicing. This ensures you get the right number of servings and makes the process much easier.

Transform Plain Cakes Into a Creative DIY Activity

If you’re someone who loves creativity but isn’t a baking expert, ordering an undecorated cake from Costco can kickstart a fun project. While Costco’s design options are limited, a plain cake gives you the freedom to personalize it however you like. Add your own touches, such as colorful icing or edible glitter, to create a unique masterpiece. Just gather your supplies and enjoy the creative process—it’s challenging but rewarding.

Freeze Any Leftover Cake for Future Enjoyment

Couples who’ve celebrated weddings often follow the tradition of freezing the top tier of their wedding cake to enjoy on their first anniversary. While freezing for a year can alter the cake’s flavor and texture, it’s a practical option for large cakes with leftovers. To freeze a cake properly, wrap it tightly in plastic wrap and then cover it with aluminum foil. Frosted Costco cakes can last several months in the freezer and should be thawed in the refrigerator when you’re ready to indulge.

Inquire About Seasonal Cake Options

Costco frequently offers seasonal designs and flavors throughout the year, adding a festive flair to your celebrations. From holiday-themed cakes to summer-inspired flavors, these limited-time options are worth exploring. In 2024, some popular seasonal items include mid-autumn moon cakes and a range of gingerbread treats for Christmas.

Confirm Availability by Calling Ahead

While custom cake orders must be placed in-store, it’s wise to call ahead and check the availability of specific desserts. This can prevent unnecessary trips, especially during busy periods or if a particular cake style is temporarily unavailable.

Cakes Can Be Returned If Unsatisfactory

Costco is known for its lenient return policy, which some argue is overly accommodating. Their satisfaction guarantee ensures that if your cake doesn’t meet your expectations, they’ll address the issue. However, returning a cake that’s mostly eaten might not be appropriate, so it’s advisable to use this policy only if there’s a significant problem with your order.
