Everything You Need to Know About Costco Bakery Treats
Planning a party or just craving a sweet treat? Costco’s bakery section is a gold mine of large‑size cakes, dense brownies, and even fancy macarons. Below you’ll find the most useful tips for choosing the right size, keeping desserts fresh, and stretching your budget.
How Big Is a Costco 1/2 Sheet Cake and Who Does It Feed?
A half‑sheet cake from Costco measures about 12 × 18 inches and weighs roughly 7 lb. In practice, you can serve 30‑40 people if you cut generous slices, or up to 50 people with smaller pieces. A good rule of thumb is to plan for 1‑1.5 oz of cake per guest for a dessert‑only menu. If you’re pairing the cake with ice cream or other sweets, aim for the lower end of that range.
Want to save space on the serving table? Cut the cake into squares and arrange them in a neat grid. This looks tidy and lets guests grab a piece without crowding around a single cake.
Storing Costco Brownies and Macarons for Maximum Freshness
Costco’s brownies are thick, fudgy, and often come in a large pan. To keep them moist, wrap the whole pan tightly with plastic wrap, then add a layer of foil. Store in the fridge for up to a week. If you need them longer, slice the brownies, place the pieces in a zip‑lock bag, and freeze. They thaw quickly in the microwave and still taste great.
Macarons are a different story. They’re delicate and can absorb moisture. Keep them in an airtight container, preferably with a paper towel on top to soak any excess humidity. Store in the fridge for up to three days; for longer storage, freeze them in a single layer and transfer to a larger container once solid.
Both brownies and macarons benefit from a quick room‑temperature sit before serving. That brings out the flavor and softens any firm edges.
Another perk of Costco’s bakery is the variety of diet‑friendly options. You’ll find vegan brownies made with plant‑based chocolate, and some locations even stock vegan cookies. Check the ingredient list if you’re avoiding dairy or eggs.
When you’re budgeting, remember that a Costco sheet cake often costs less per slice than ordering multiple small cakes from a boutique bakery. The same goes for bulk brownies—one large pan can feed a crowd for a fraction of the price of individual servings.
Finally, think about presentation. A simple dusting of powdered sugar on brownies or a drizzle of chocolate ganache on a sheet cake can make the dessert look bakery‑level without extra cost. Use fresh berries or a few sprigs of mint for a pop of color.
With these tips, you can turn Costco’s bakery staples into the centerpiece of any gathering. Whether you’re feeding a family dinner, a birthday party, or just satisfying a sweet tooth, Costco has the size, price, and variety to cover it.
