Measure quinoa and add to a small saucepan over medium heat. Stir periodically while heating, to ensure the seeds to not burn. When they begin to pop, keep stirring for another minute, then remove from heat to cool.
When the quinoa has cooled, add to the bowl of a food processor or blender. Pulse until the seeds have mostly been ground into a fine powder. Re-measure the flour and save any extra for another recipe or to sprinkle on cereal or yogurt for added protein.
Measure gluten free oats and add to the bowl of a food processor or blender. Pulse until the oats have been ground into a fine powder. Re-measure the flour and save any extra for another recipe or to sprinkle on cereal or yogurt for added fiber.
Repeat to grind flax seeds, or measure out flax seed meal.
In a small bowl, whisk together all measured gluten free flours with baking powder.
In another bowl, stir 1/2 cup milk, oil and egg until combined. Reserve 1/4 cup milk.
Stir in the dry ingredients, adding enough milk to form a batter. Add more milk gradually, if the mixture is too thick. The batter should not be runny, but be easily spread with the back of a spoon.
Heat a large pan or griddle and spoon pancakes out onto the medium-hot surface. Oil is not necessary if using a non-stick pan; otherwise, add enough cooking oil to lightly coat the cooking surface before spooning out pancake batter. Add berries or nuts to the pancakes, if desired, and flip when lightly browned on the bottom.
Serve warm with pure maple syrup or fruit.
