Whether you like it or not, pumpkin season—at least when it comes to food—is officially in full swing. Starbucks just brought back the Pumpkin Spice Latte, and now Costco’s bakery is rolling out one of its first big fall-inspired treats.
The new Pumpkin Spice Bar Cake weighs in at a hefty 2.5 pounds and yields around 20 slices. After learning about the layers of this cake, it sounds exactly like the kind of Costco dessert you bring home for everyone to try and then slowly realize you want to keep for yourself.
The cake is made with layers of super-moist pumpkin spice sponge cake and creamy pumpkin mousse, finished with a smooth frosted top and decorative detailing. The pumpkin flavor leans into classic fall spices, including cinnamon and nutmeg, so this is very much for anyone who starts craving cozy desserts the second August begins wrapping up.
And judging by the early fan reactions, shoppers are already fully on board.

“This is just perfect for cozy weather 😍🤎🍁🍂,” one commenter wrote, while another gave it a very direct endorsement: “10/10 delish!!! I love this cake!!”
Someone else added, “Do not pass this delicacy up. It’s amazing!” and another shopper admitted, “Damn it I’m not gonna be able to say no to this.”
The most relatable reaction, though, might have been from one fan imagining exactly how they’d serve it: “Goodness grief, could you imagine a pumpkin spice latte with a slice of this 😂”
Even one commenter who was still scarred by a previous Costco bakery purchase seemed tempted after the creator reassured them that this cake was “SO moist!”
So if pumpkin spice is already taking over your coffee order, you may as well make room for it in your dessert rotation too. At 2.5 pounds, Costco’s new Pumpkin Spice Bar Cake is basically built for a fall gathering, or several nights of standing in front of the fridge with a fork.
