Ingredients

Optional Add-ins

Instructions

  • Add all ingredients in the order in which they appear to a microwave-safe mug or measuring cup. Stir in the chocolate chips (if adding).
  • Microwave on high 40 to 60 seconds, until cookie has set up.
  • Allow cookie to cool for 1 minute before enjoying.

Notes

*I have found various gluten-free flour blends have different absorbencies so the results may vary depending on what brand of GF flour you use. I use Bob's Red Mill Gluten-Free 1-to-1 Baking Flour but have found the recipe results in a greasier cookie when I use Pamela's. 
For a smaller cookie, make this recipe:
  • 3 Tbsp gluten-free all-purpose flour
  • 2 Tbsp quick oats or rolled oats
  • 1.5 Tbsp sugar
  • 2 Tbsp avocado oil
  • 1 Tbsp water
  • Pinch sea salt
  • Pinch ground cinnamon
Microwave for 60 seconds.
