Easy peanut butter powder cookies you can made with PB2 or other brand of powdered peanut butter and taste just like a classic peanut butter cookie.


  • ¼ cup plant-based butter, softened (56 g)
  • ½ cup granulated sugar (96 g)
  • 1 tbsp flaxseed (11 g) + 3 tbsp water
  • 1 tsp vanilla extract
  • ¾ cup powdered peanut butter (72 g)
  • ¾ cup oat flour (90 g)
  • 1 tsp baking powder
  • ¼ tsp salt


  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.
  2. Beat Wet Ingredients: In a large bowl, beat together the softened butter and sugar until well combined. Beat in the flax egg and vanilla extract.
  3. Add Dry Ingredients: Add the powdered peanut butter, oat flour, baking powder, and salt to the bowl and mix gently to combine. 
  4. Shape Cookies: Once dough is evenly combined, scoop dough into heaping tbsp-sized balls and place on the baking sheet. Press down on each ball with your hand or the back of a spoon so the cookies are about 1-cm thick. Feel free to use a fork to make the classic peanut butter cookie look.
  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.


Store cookies at room temperature for up to 4 days, in the fridge for up to 1 week, or in the freezer for up to 3 months.
