  • Yield: 10-12 cookies 1x


Super simple, one bowl gluten free and vegan peanut butter oat cookies. The perfect healthy treat or snack. Easily made with tahini, almond butter, or sunflower butter.


  • 1 tbsp ground flax seeds (flax meal) ** see note
  • 3 tbsp warm water
  • 1/4 cup peanut butter, almond butter, tahini, or sunflower butter
  • 2 tbsp melted coconut oil or avocado oil
  • 1 tsp vanilla extract
  • 1 cup GF oats
  • 1/4 cup GF oat flour (like this or grind your own)
  • 1/3 cup coconut sugar
  • 1/4 tsp salt
  • optional topping: coarse salt



  1. Make flax egg by whisking together 1 tablespoon of ground flax seeds and 3 tbsp warm water.  Allow to sit for 10 minutes to gel.
  2. Preheat oven to 350’F. Line baking sheet with parchment paper.
  3. In a mixing bowl, whisk together flax egg, peanut butter, fat of choice, and vanilla until creamy smooth.  Add rolled oats, oat flour, coconut sugar, and salt. Mix until well incorporated.
  4. Using a small cookie scoop, drop small cookie balls onto prepared baking sheet.  Flatten with fingers or fork to desired thickness.  These cookies will not spread.
  5. Bake for 12-14 minutes, until firm and golden on the bottom. Allow cookies to cool for 5 minutes on the baking tray then transfer to a wire rack to cool completely. Top with a bit of optional coarse salt while cooling.




While you can purchase flax meal at most health food store or online, I prefer to grind my own. The delicate healthy fats in flax seeds can go rancid easily. I keep my flax seeds in the refrigerator and grind up a bit in my coffee grinder when I need some flax meal. Simply place whole flax seeds into coffee grinder and grind until fine. Store any unused flax meal in an air tight glass jar in the fridge.
