What is peanut butter powder?

Peanut butter powder, or powdered peanut butter, is a convenient product made from roasted and pressed peanuts that have much of the oil and fat removed before being grinded into a fine powder.

The process reduces the fat content making peanut butter powder is lower in fat and calories than peanut butter, while still containing some protein.

It’s versatile and can be added to smoothies, baking, soups, curries and sauces, or rehydrated with water to make a spread.

Ingredient Notes

Ingredients for making peanut butter powder cookies. Each ingredient is labelled.

The full list of ingredients with measurements can be found in the recipe card at the end of the post. This list provides any notes on specific ingredients and possible substitutions.

  • Butter: You can use any plant-based butter or butter or substitute melted and cooled coconut oil.
  • Sugar: You can use granulated sugar or substitute coconut sugar or brown sugar. Monk fruit sweetened would work for a sugar-free version. Coconut sugar has a stronger flavour and darker colour that comes through in the baked cookies.
  • Flax: Be sure to use ground flaxseed, not whole flaxseeds.
  • Powdered Peanut Butter: Any brand of powdered peanut butter such as PBFit or PB2, or powdered almond butter works.
  • Oat Flour: You can use homemade or store-bought oat flour. You can substitute all-purpose flour or gluten-free all-purpose flour.

Variations & Additions

  • For peanut butter oatmeal cookies, add 1/2 cup rolled oats.
  • Add up to 1/2 cup chocolate chips or mini chocolate chips to make chocolate chip cookies.
  • Sprinkle with flaky sea salt after baking.
  • Add up to 1/2 cup chopped nuts such as peanuts, walnuts, pecans or almonds.
  • Create a well in the center of each cookie and add a teaspoon of jam to make peanut butter thumbprint cookies.

Ground flaxseed mixed with water in a small dish to form a gel-like flax "egg".

Step 2: Beat together the softened butter and sugar until well combined, then beat in the flax egg and vanilla extract.

Note that I used coconut sugar which is why it’s so dark. If you use granulated sugar it will be lighter in colour.

Expert Tips

  • Use a digital kitchen scale to accurately measure ingredients.
  • Avoid over baking the cookies or they’ll be dry. The cookies may seem under done when they come out of the oven but will quickly firm up as they cool.
  • The cookies don’t spread in the oven so be sure to press them down before baking.

  1. Prepare: Preheat the oven to 350˚F (175˚C) and line a baking sheet with parchment paper. While the oven is preheating, make your flax egg by mixing together the flaxseed and water in a small bowl. Let sit for at least 5-10 minutes while you gather the rest of the ingredients.

  5. Bake Cookies: Bake at 350˚F (175˚C) for 10-12 minutes, until the bottoms of the cookies are just turning golden brown. Let sit on the baking tray for at least 5 minutes before transferring to a wire rack to finish cooling.
