Preheat oven to 350°F (175°C). Line a muffin tin with paper liners.
In a large bowl, mix quinoa flour, almond flour, sugar, baking powder, baking soda, and salt.
In another bowl, whisk together milk, coconut oil, eggs, and vanilla extract.
Pour wet ingredients into dry ingredients and stir until just combined.
Gently fold in blueberries.
Divide batter evenly among muffin cups.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
