On any given day, you will find chocolate and vanilla round Bakery Costco cakes in the refrigerated case in the bakery – there are generally plain cakes without a design, a seasonal design (for example Footballs around the Superbowl or red/white/blue stars at Fourth of July), and a simple birthday design (usually balloons with “happy birthday”). And you’ll also find cheesecakes, mini cakes, special order deli platters and other prepared desserts.

The good news on the advanced ordering is that they don’t need a lot of lead time! Yay for that because advance planning isn’t our speciality, lol. The Costco Bakery only needs 24 hours notice for orders with your choice of sheet cake designs.
