Preheat oven to 400 degrees F and grease 8″ x 5″ loaf tin with butter or coconut oil well.
In a high-speed blender or food processor, grind quinoa for a few minutes until flour forms. Transfer to a large mixing bowl along with oat flour, baking soda, baking powder and salt; stir very well. Add butter or coconut oil and stir until it is incorporated with dry ingredients in small pieces.
In a medium bowl, whisk milk, maple syrup and vinegar. Pour into a bowl with dry ingredients and mix well with spatula.
Transfer to a prepared loaf tin, level and sprinkle with sesame seeds if desired. Bake for 60 minutes loosely covered with parchment paper for the first 30 minutes to prevent top from burning. Remove from the oven and let cool for about an hour. Then loosen the sides with a knife, flip the tin and give a few gentle pats on a bottom. Bread should slide out and cool off completely before slicing.
Store: Refrigerate in a sealed plastic bag for about 2 weeks. Freeze for up to 3 months.
*Make oat flour by grinding quick or rolled oats. I think ratio is 1:1 but measure after anyways. Also you can use spelt or whole wheat flour in place of oat flour. Bread will be dryer and nuttier but still good. I prefer oat flour. For gluten free bread version use Gluten Free certified oats.
