Preheat oven to 350 degrees F. Line an 8 x 8 baking pan with parchment and set aside.
Beat together banana, avocado, tahini, sugar, eggs and vanilla until smooth and creamy.
Add to quinoa flour, raw cacao, baking soda and salt, mixing until incorporated. Fold in chocolate chips.
Transfer batter to the prepared baking pan. Press it into the corners of the pan using wet hands or a pastry roller. Bake on the center rack for 20 – 24 minutes.
Remove from the oven and let the brownies cool in pan completely before slicing into squares. (*very important or they'll be crumbly!!*)
Store in a sealed, airtight container for optimal fudginess.
