Costco Peanut Butter Powder: PBfit Organic Review, Price & Where to Find It

By CostcoFan | Updated June 2026

PBfit Organic Peanut Butter Powder, 30 oz Costco Item #1726362 (bag) | Online at Costco.com

If you’ve been hunting for the Costco peanut butter powder — the PBfit you used to grab in the big plastic tub — here’s the full rundown: what changed, the price, why people are obsessed with it, the honest downsides from 200+ reviews, and the big question everyone’s asking lately: why can’t I find it in the warehouse anymore?

PBfit Organic is powdered peanut butter — real roasted peanuts with most of the oil pressed out, so you get the peanut flavor and protein with a fraction of the fat and calories. It’s become a cult staple for the smoothie, oatmeal, and protein-shake crowd, and Costco has long had one of the best prices on it.

What Is PBfit / Peanut Butter Powder?

Powdered peanut butter is made by roasting peanuts and pressing out most of the natural oil, then grinding what’s left into a fine powder. You mix it with water to make a peanut-butter-like spread, or add the dry powder straight into smoothies, shakes, oatmeal, yogurt, or baking.

The appeal is the nutrition swap: PBfit has roughly 87% less fat and about a third of the calories of traditional peanut butter, while keeping the peanut taste and adding protein. A common serving is about 60 calories per 2 tablespoons. For anyone tracking calories, hitting protein goals, or just wanting peanut flavor without the heaviness of regular PB, it’s a genuinely useful pantry item — and reviewers use it in everything from Pad Thai sauce to protein balls to coffee.

Quick name clarification: you’ll see this product searched as PBfit, PB Fit, PB2, peanut butter powder, and PB powder — PB2 is actually a different brand of the same type of product. Costco’s current item is PBfit Organic specifically. If you came looking for “PB2 at Costco,” this PBfit is the powdered peanut butter Costco carries.

Costco PBfit Price

Costco sells the 30 oz bag of PBfit Organic at a strong per-ounce price compared to buying it at regular grocery stores or in smaller bags online — it’s consistently called out in reviews as the best price people have found. The exact price varies, so check the current listing, but the large-bag format is where the Costco value comes in.

One value note from longtime buyers: the switch from the old large plastic tub to the resealable bag made it slightly more expensive per ounce for some, but plenty of buyers actually prefer the bag for less plastic waste and easier storage.

The Bottle-to-Bag Change (and the Item Numbers)

If you’re a longtime buyer, you may remember PBfit coming in a big plastic tub — that was the old version (Item #1054222). Costco has since switched to a 30 oz resealable bag (Item #1726362).

This trips people up, so to be clear: it’s the same type of product — PBfit Organic peanut butter powder — just repackaged from the tub into a bag. Reviewers are split: some miss the tub, but many prefer the bag for taking up less space and using less plastic. If you’re searching for the old tub item number and can’t find it, the bag (#1726362) is the current version.

Is Costco PBfit Worth It? (What 200+ Reviews Say)

Across more than 200 Costco reviews, PBfit Organic averages strongly positive, and the praise is remarkably consistent. Here’s the honest breakdown:

What people love:

The nutrition swap — peanut flavor and protein with far less fat and calories is the #1 reason people buy it
Versatility — smoothies and protein shakes are the top uses, but reviewers also use it in oatmeal, yogurt, coffee, baking, peanut sauces (Pad Thai), and protein balls
Taste — most say it genuinely tastes like peanut butter; many call it a permanent replacement for the jar
Easier on the stomach — a few reviewers note it doesn’t give them the reflux that regular jarred PB does
The Costco price and big bag size

The honest downsides:

Sweetness is divisive. This is the most common complaint — it contains added sugar, and some buyers find it too sweet or wish they’d known about the sugar before buying. If you want unsweetened, this may not be your pick.
The resealable zipper — a couple reviewers found the bag’s seal finicky to close.
Texture/mixing — you need the right powder-to-water ratio (many like 2 Tbsp powder to 2 Tbsp water); too little water leaves clumps.

Bottom line: if you want a lower-calorie, higher-protein way to get peanut butter flavor into shakes and recipes, it’s an easy recommendation — just know it’s lightly sweetened, not a plain peanut powder.

Is Costco PBfit Available In Stores? (Availability)

Here’s the question that comes up constantly in recent reviews: PBfit has largely moved to online-only at Costco. A huge number of buyers report it’s disappeared from their local warehouse shelves and that they can now only get it on Costco.com — with many pleading “please put it back in stores.”

So as of this update, the most reliable way to get the Costco peanut butter powder is online at Costco.com (Item #1726362), shipped to you. Some warehouses may still carry it regionally or intermittently, but it’s no longer a guaranteed in-store item. The fastest way to check your specific warehouse: look up Item #1726362 in the Costco app (Warehouse tab), or call your store with that number. If it’s not there, the online listing is your best bet.

(Worth noting: some longtime buyers worry the in-store disappearance means it could be discontinued eventually — so if you rely on it, the online listing is the safe source for now.)
