For the perfect potluck dessert, try Costco's chocolate peanut butter pie. It's loved for its taste, size, and convenience, and at nearly 5 pounds, this luxurious dessert is a hit.

Reminiscent of Reese's peanut butter cups, the $19.99 pie is filled with chocolate and peanut butter. It is a massive dessert, ensuring plenty of helpings at potlucks.

Though pricey, it's made fresh in the bakery, and you won't be able to find this pie anywhere else. TikToker CostcoHotFinds claims the pie can be cut into at least 16 portions.
