Costco's Chocolate Peanut Butter Pie Is The Perfect Potluck Dessert

Deciding what dessert to bring to a potluck can be difficult, especially if the gathering is days away. If you don't already have a sweet treat in mind, you'll want to consider how many mouths there are to feed and how many other desserts will be spread out on a table. While you could bake a pie or cake yourself, it's much more convenient to pick up a dessert at the store. No one will think less of you for it — particularly if you arrive with one of Costco's chocolate peanut butter pies.

It shouldn't come as a surprise that Costco is a popular place to shop for a potluck. Whether cooking a casserole from scratch or securing a container of premade potato salad, many shoppers find the wholesaler's offerings impressive in both scope and size. And when it comes to the treats made fresh by Costco's bakery, the decadent desserts are no exception.

While the company is known for its seasonal fall-favorite pumpkin pie, which weighs 3.6 pounds, the chocolate peanut butter pie is available year-round and is much larger. Fit to feed a huge group, it packs almost 5 pounds of chocolate and peanut butter cream into a buttery graham cracker crust. The luxuriously rich dessert first appeared in Costco warehouses in March 2023 and was an instant hit among members. It's safe to say it'll be just as popular at any potluck you attend.

You can't go wrong with chocolate and peanut butter. The pairing marries the sweetness of chocolate with the saltiness of peanut butter — a union that's as rich as it is comforting. In this way, Costco's chocolate peanut butter pie is comparable to a giant, creamy Reese's peanut butter cup, and many members of the bulk retailer seem to find it downright irresistible. In a discussion on Reddit, one user commented, "I REALLY wanted it to suck. I wanted to buy it once, realize it was a mistake, and be happy to walk past it every time in the future. But damn is it delicious. Now I'm going to have to walk past it in absolute agony."

Of course, flavor isn't the only important hallmark of a crowd-pleasing potluck dessert. It's standard etiquette to bring something that's appropriately sized for the number of guests attending. Fortunately, this chocolate peanut butter pie is massive. In its entirety, the dessert weighs 4.5 pounds, which makes it significantly larger than other Costco pies. Pictures don't quite do it justice, though.

The only downside to this Costco pie is that it's somewhat pricy. Compared to the company's pumpkin pie, which has remained shockingly cheap for decades, the chocolate peanut butter pie costs $19.99. However, since it's made fresh at Costco's bakery, it's hard to imagine you could spend less on ingredients by baking one at home, let alone find a similarly sized option at a local bakery.

There's no debate that this chocolate peanut butter pie is massive, but there might be some doubt as to how many people it can actually feed. While the savory pizza pies sold at Costco's food court standardly come precut into a certain number of slices, this sweet one is sold whole and unsliced. Ultimately, you can choose to cut it into thin slivers or thick wedges depending on the total number of guests.

However, for some perspective, Laura Lamb, the creator behind the CostcoHotFinds TikTok account, told Today that the pie could be split into at least 16 portions. Since the combined chocolate and peanut butter creams are fairly rich, it seems like a small slice will go a surprisingly long way — even at a packed potluck. Worst case, you can always splurge on another pie.

If you do opt for a second or simply end up with leftovers, storing Costco's chocolate peanut butter pie is fairly straightforward. Since the container is so big, it's most convenient to store any remaining slices in an airtight container. Store extra slices in the fridge if you plan to finish them in the next few days; otherwise, pop the leftovers into the freezer for a cold treat during a sweltering summer day. Of course, chances are that any lingering potluck attendees probably won't complain if they're sent home with an extra slice or two.
