PB2 powder, also known as peanut butter powder, has become a popular item in many kitchens due to its versatility and nutrition. But like with many shelf-stable foods, people often wonder – does PB2 powder expire? Let’s take a closer look at the shelf life and expiration of this handy powder.
What is PB2 Powder?
PB2 powder is made from roasted peanuts that have been pressed to remove most of their natural oils. The resulting powder has 85% less fat than traditional peanut butter, but still boasts peanut flavor. PB2 powder is often used to make peanut butter spreads, smoothies, baked goods, and more. It mixes well with water or milk to form a peanut butter-like consistency.
Does PB2 Powder Go Bad?
Yes, PB2 powder does eventually expire and go bad. However, the shelf life is quite long compared to many other cooking ingredients. An unopened package of PB2 powder typically lasts about 1 year past its “best by” date printed on the packaging.
Once opened, the shelf life is reduced to just 3-4 months. This is because exposure to air starts to slowly degrade the quality and flavor of the powder. Heat and humidity can also accelerate spoilage in opened packets.
How to Tell if PB2 Powder is Bad
Here are some signs that your PB2 powder has gone bad and should be discarded:
- Expired date on packaging
- Noticeable rancid peanut odor
- Darkening color
- Hardened or caked powder
- Change in flavor when mixed into recipes
If your powder displays any of these characteristics, it is best to throw it out and purchase a fresh package. Using spoiled PB2 can negatively impact the taste of foods you add it to.
Does Refrigeration Extend Shelf Life?
Refrigerating unopened PB2 powder is not necessary, but can help extend the shelf life by a few months past the printed “best by” date. Once opened, keeping PB2 powder in the refrigerator is recommended to slow spoilage.
Make sure to store the powder in an airtight container or resealable plastic bag when refrigerated. This prevents it from absorbing fridge odors. Properly stored in the fridge after opening, PB2 powder can last upwards of 6 months.
Can Expired PB2 Powder Make You Sick?
Consuming PB2 powder that has gone bad is not likely to cause food poisoning or illness. However, rancid peanut products don’t taste very pleasant. The flavor and texture degradation will be readily apparent if you try to use spoiled PB2.
As long as the powder shows no signs of mold, it is not considered unsafe to ingest. But for the best flavor and cooking results, be sure to discard PB2 that is past its prime.
How to Store PB2 Powder
To get the longest shelf life out of your PB2 powder purchase, proper storage is key. Here are some tips for keeping PB2 fresh for as long as possible:
- Keep unopened packets in a cool, dry pantry away from heat and sunlight.
- Once opened, transfer to an airtight container or heavy-duty plastic bag.
- Squeeze out excess air and seal the container tightly.
- Refrigerate after opening to extend shelf life.
- Use clean, dry utensils each time you scoop out powder to prevent contamination.
- Use within 3-4 months and discard if you notice any signs of spoilage.
The Shelf Life of PB2 Powder
Here is a summary of the shelf life expectations for PB2 peanut butter powder:
| Storage Method | Unopened Shelf Life | Opened Shelf Life |
|---|---|---|
| Pantry | 12 months past “best by” date | 3-4 months |
| Refrigerator | 18 months past “best by date” | 6+ months |
Be sure to store PB2 powder properly to get the most out of each package you purchase. Also, pay close attention after opening for any signs of spoilage.
Does PB2 Powder Need to be Refrigerated After Opening?
Refrigeration is recommended for PB2 powder after opening to extend the shelf life. While not strictly required if consumed quickly, keeping the powder chilled after exposure to air will maintain quality and freshness for longer.
Make sure to transfer opened powder to an airtight container or bag before storing in the refrigerator. This prevents it from absorbing odors from other foods.
Properly stored in the fridge, opened packets of PB2 powder will stay fresh for 6 months or more. Without refrigeration, the opened powder only lasts 3-4 months.
Can You Freeze PB2 Powder?
Freezing is not recommended for PB2 peanut butter powder. The powder may clump together when frozen, making it difficult to scoop out of the package after thawing.
If freezing cannot be avoided, it’s best to portion PB2 powder into airtight bags or containers first. Remove as much air as possible before sealing. Thaw completely in the refrigerator before using.
Freezing can also degrade the quality and flavor over time. For best results, opt for refrigeration over freezing if storing opened packets for more than a few months.
How to Use Up PB2 Powder
If you have a package of PB2 powder that is nearing expiration or past its “best by” date, here are some tips for using it up quickly:
- Make peanut butter energy balls or no-bake granola bars.
- Mix it into oatmeal or chia pudding.
- Blend it into smoothies for extra protein.
- Whisk it with coconut milk for thai peanut sauce.
- Fold it into cookie dough or baked goods.
- Sprinkle it on top of yogurt bowls or fruit salads.
- Add it to pancake or waffle batter.
- Use it in any recipe calling for peanut butter like sandwiches.
Getting creative with recipes can help you use up PB2 powder rapidly so none goes to waste. Explore blending it into shakes, spreads, baked goods, snacks, sauces, and more.
PB2 Powder Substitutes
If you don’t have any PB2 powder on hand, there are a few substitutions you can use:
- Traditional peanut butter – Use 3 tablespoons powder per 1 tablespoon regular peanut butter.
- Other nut butters – Try almond or cashew butter for a different flavor.
- Sunflower seed butter – For a nut-free option with a similar consistency.
- Ground roasted peanuts – Lacks the powder’s smoothness but provides flavor.
- Soy nut butter powder – For a peanut-free choice that behaves like PB2.
These alternatives can work in a pinch, though the flavor and nutrition profile won’t be exactly the same as PB2. Tweak any recipes as needed when using substitutions.
Should You Stock Up on PB2 Powder?
Because of its long shelf life, PB2 powder can be a smart item to buy in bulk when it goes on sale. Stocking up can save money over time.
Just be sure to store unopened jars in a cool, dry place like the pantry. Write the purchase date on each jar for reference. Rotate through the stock, using the oldest packages first.
Once opened, PB2 powder only lasts around 4 months. So purchase amounts that can reasonably be used up within that timeframe after opening.
Frequently Asked Questions
Does PB2 powder need to be refrigerated?
Refrigeration is not required for unopened packets, but can extend the shelf life. Once opened, it is recommended to refrigerate PB2 powder to maximize freshness.

Rancid PB2 powder does not pose any health risks, but it will taste unpleasant. The flavor and aroma degrades over time past the expiration date.
Can you freeze PB2 powder?
Freezing is not recommended. It may cause clumping and degrade the quality over time. Refrigeration is better for storing opened containers.

It is not dangerous, but the taste and texture quality declines after the printed best by date. Old powder may have an off flavor, color, or aroma.
Does PB2 go bad if not refrigerated?
Yes, PB2 will eventually expire if left at room temperature. Refrigeration can prolong the shelf life after opening. But even refrigerated, it goes bad within 6 months.
The Bottom Line
With proper storage, PB2 powder can last over a year past its printed expiration date when sealed. But once exposed to air, it only stays fresh for 3-4 months, or up to 6 months when refrigerated. Keep an eye out for any changes in color, texture, or smell over time. Portioning powder into smaller containers can help reduce waste if you won’t use it quickly. Be diligent about watching expiration dates, and your PB2 powder purchases can remain fresh for their full shelf life.
