If you spot the seasonal confection, snatch it up before it's gone!
I Tried the Costco Peaches and Cream Bar Cake and Had to Buy One
Published on Jun. 27, 2025
It’s hard to resist the plethora of samples available on a trip to Costco. After all, the samples are unlimited. There’s always something new to taste and, more often than not, I end up with some of them in my cart. On a recent trip, there was a suspiciously long line in the bakery section with shoppers eager for something sweet. As I inched closer, I saw slices of a brand new cake getting snatched up as soon as they were plated. The sample was the Costco peaches and cream bar cake, and I was lucky enough to snag a bite.
What is Costco’s peaches and cream bar cake?
The peaches and cream bar cake is 37 ounces of dessert bliss, with fluffy whipped cream and tart peach filling sandwiched between layers of vanilla sponge cake. I loved the delicate white chocolate curls on top as an extra flourish. For $18.99, this large dessert is a bargain for serving a crowd. The size and shape is consistent with Costco’s other bar cakes, like the springtime carrot bar cake or everyone’s favorite tuxedo mousse cake, which is a staple in the bakery case.
How did the Costco peaches and cream bar cake taste?
After the first bite of the sample, I knew this cake was coming home with me. I certainly hope it becomes an annual flavor offering, because I would line up to buy it again. The texture was delightfully light and airy, as a perfect sponge cake should be. Since it’s made with whipped cream rather than heavier buttercream frosting, this also contributed to it being more delicate. Several Reddit users had the same thought as me: Rather than being too sweet, this cake leaned more tart because of the peaches.
The cake would be perfect to serve at a summer baby or bridal shower. I think it would also be a big hit at a graduation party. The flavor profile makes it a great choice to serve after a heavier meal like a summertime backyard barbecue.
How long will the peaches and cream bar cake be at Costco?
Costco loves to be secretive about the comings and goings of its products, so there’s no real way of knowing how long this cake will remain on store shelves. However, at the rate they were being snatched up, I’d say this cake is selling fast. If you’re interested in getting one for yourself, time is of the essence!
