Pumpkin spice season officially has a new mascot, and it’s not a latte. Costco just brought back its Kirkland Signature Pumpkin Spice Bar Cake, and shoppers are already elbow-deep in the bakery case trying to snag one before it disappears. At $16.99 for a cake that serves around 20 people, it’s quickly becoming the fall dessert everyone’s talking about — and yes, TikTok has thoughts.
If your feed has been flooded with layered pumpkin desserts lately, this is probably why. Let’s get into what makes this one worth the trip.
What’s Actually In This Thing
This isn’t just a slab of frosted pumpkin bread. The Kirkland Signature Pumpkin Spice Bar Cake (item #2067640) is built like a proper layer cake, just in rectangle form: three layers of moist pumpkin spice sponge cake alternating with two layers of fluffy pumpkin mousse, all topped off with cream cheese frosting and a scattering of white chocolate curls. It weighs in at about 2.5 pounds, which is bakery-speak for “you will absolutely have leftovers, and that’s a good thing.”
“The cake is SO moist!! 10/10 this cake screams fall.”
That’s the verdict from Instagram creator @costcohotfinds, who posted a close-up look at the returning bakery favorite in late August. And on TikTok, the reviews are just as glowing — one creator gave it a 9 out of 10, calling it “not too sweet” with “great flavor,” which is basically a five-star Yelp review in TikTok years.
Do the Math on This Deal
Here’s the part that makes this a genuine Grocery Goodies favorite: $16.99 divided across roughly 20 slices comes out to about 85 cents per serving. For a dessert with three types of texture happening in every bite, that’s a ridiculously good price for feeding a crowd — whether that crowd is your extended family at a fall gathering or just you and a fork on a Tuesday night.
It’s giving major bakery-case energy similar to Costco’s Kirkland Marshmallow Crispy Cookies, which also turned into a TikTok bakery mashup moment earlier this fall. Costco’s dessert case has quietly become one of the most reliable sources of viral food content in the entire warehouse.
How to Actually Get One
Like most Costco bakery finds, this one plays hard to get. Pricing and availability can shift by warehouse, and seasonal items don’t stick around once pumpkin spice season wraps up. Your best bet is to check the bakery case near the entrance (not the shelf-stable aisle) and go early in the day — fall bakery items have a habit of vanishing by the afternoon rush, the same way Costco’s Twice-Baked Cinnamon Croissants tend to sell out before noon on weekends.
If you’re worried about finishing the whole thing before it goes bad, good news: this cake freezes well. Skip freezing the entire cake at once — instead, slice it into individual portions first, wrap each piece tightly, and store them together in a freezer-safe bag or container. That way you can pull out exactly one pumpkin craving’s worth whenever you need it, even after the bakery case has moved on to gingerbread.
Worth the Trip?
If you’ve been stocking up on fall flavors already — maybe alongside Aldi’s Berryhill Spread for your morning toast — this cake is a natural next stop on the pumpkin spice grocery tour. Between the price per slice, the layered texture, and the fact that half the internet is already obsessed, it’s hard to argue against grabbing one for your next gathering.
Just don’t wait too long. Seasonal Costco bakery items have a way of disappearing right when you’ve decided you can’t live without them. Grab yours, snap the obligatory slice photo, and let us know in the comments if it lives up to the 10/10 hype.
