Costco PB Fit Peanut Butter Powder Review

Are you a big peanut butter fan but worry about how many calories and how much fat it has? The Costco PB Fit Peanut Butter Powder has 87% less fat than traditional peanut butter but does it have the same delicious flavor?

I’m a big peanut butter fan and don’t mind the healthy fat in it one bit but I wanted to try this PB Fit Peanut Butter Powder from Costco because I thought it would be awesome to add to oatmeal and smoothies.

Other nutty products from Costco are the Kirkland Signature Mixed Nut Butter with Seeds, Savanna Orchards Country Club Nut Mix, Kirkland Signature Honey Roasted Macadamia Nuts, Kirkland Signature Natural Peanut Butter, Kirkland Signature Peanut Butter Cookies, Kirkland Signature Nut and Seed Brittle, PB2 Powdered Peanut Butter, Nuts for Nature Nut and Seed Butter and the Kirkland Signature Almond Butter.

Location in Store

You can find this powdered peanut butter in the aisle with the other nut butter, jam and syrup. The item number is 1193520.

The powder is light and very fine.


I love peanut butter but can’t say I enjoy this as much as regular peanut butter, not even close. I find the powdered peanut butter really sweet tasting.

I followed the recipe on the container and the consistency of the PB Fit is thinner than I would like. It’s quite runny. I also notice a chalky taste as well as an artificial flavor, not like natural peanut butter.

The texture isn’t as thick as traditional peanut butter.

The PB Fit doesn’t taste bad, it just isn’t nearly as good as natural peanut butter. I tried some spread on toast and found it was really lacking in flavor. I find natural peanut butter very flavorful.

Smooth and a bit runny after preparing according to the directions.


The 850-gram container costs $12.99 Canadian which seems expensive but I think the price is related to it being marketed as a lower-calorie, healthier substitute for peanut butter.

Storage information and preparation instructions.


The best-before date listed on the container is 17 months from the date I purchased it. The powder should be stored in a cool, dry, dark place and if the powder has been mixed it needs to be consumed immediately.

Product description from the back of the container.
The PB Fit has less calories and fat compared to traditional peanut butter.

There are many ways to use powdered peanut butter like in oatmeal, smoothies, on toast, mixed with yogurt or in baking. You don’t have to prepare the peanut butter to add it to smoothies or oatmeal, I just would sprinkle a little bit of powder in.

Comparing PB Fit nutrition information with traditional peanut butter.



One tablespoon of powdered peanut butter contains 35 calories, one gram of fat, three grams of carbohydrates, one gram of fibre, one gram of sugar, four grams of protein and 75 milligrams of sodium. That’s actually quite a bit of protein for not that many calories, fat or sugar!

If you’re trying to lose weight or watch your caloric or fat intake this is a great way to still enjoy peanut butter for a lot fewer calories and fat.

Nutrition facts.


There are only three ingredients in the Costco PB Fit Original Peanut Butter Powder. If you don’t know, coconut palm sugar is made from coconut palm sap and although it may seem healthy it’s really not much better than cane sugar. All natural peanut butter doesn’t have any added sugar.

Taste: 7/10

Cost: 8/10

Convenience: 10/10

Nutrition: 8/10


Give it a try (if you’re watching your calories or fat intake and want to enjoy something similar to peanut butter).

I prefer regular peanut butter but if I’m looking for a bit of peanut butter flavor in oatmeal or smoothies and am trying to keep it a bit lower in calories or fat I’d use this.

  1. Love this stuff. I usually use one part PB powder with 2 parts chocolate protein powder to make my smoothies. Also 1/2 banana and 1 large spoonful of ground flax.

  2. Oh Natalie, I’m so happy you are review this product. Which Costco did you get it? I saw it last year in Costco when I was in Calgary and thought “No need to buy it here and carry it all the way back to Edmonton.” But when I was back in Edmonton, I searched for it in 3 Costco locations and never found it!

  3. Thanks for the review. Not sure why they need to add sweetener. I used to buy the PB&Me unsweetened from Costco online. But it’s no longer on their website. The best brand I’ve found is from Naked Nutrition. I used to buy on but it is also not available at the moment.

    I like that the powder is shelf stable so I can mix it up as I need and not worried about a whole jar going rancid. Esp since I am the only PB lover in the family. I can also add in flavourings such as matcha or cacao.

  4. I really can’t think of a reason to use this product over real peanut butter, so I haven’t. By all accounts, it is lacking in flavour, consistency and texture… with chalky and artificial flavor.

    How is it any more convenient when I have to prepare it every time I want to use it if I’m putting it on toast or putting some on a banana. Mixing real peanut butter into a smoothie or another recipe is simple… throw it in the microwave for 10 seconds if it is too thick.

    Powdered PB is yet another example of what happens when food manufacturers swap out fat for sugar. If you think avoiding fat and calories is a weight loss strategy, think again!

    • I mean… yes, consuming less calories is a weight loss strategy. In fact, it’s the best weight loss strategy, considering the only way to lose weight is to consume less calories than you burn.
