In a large mixing bowl, whisk together the quinoa flour, baking powder, baking soda, and sea salt until well combined.
In a separate bowl, whisk together the slightly beaten eggs, coconut oil, honey, and kefir (or buttermilk) until smooth.
Pour the wet ingredients into the dry ingredients. Gently fold the ingredients together until just combined.
Fold in the fresh blueberries and walnuts (if using), ensuring they are evenly distributed throughout the batter.
Preheat a non-stick skillet or griddle over medium heat.
Pour about 1/4 cup of batter onto the skillet for each pancake. Cook for 2-3 minutes or until bubbles form on the surface. Flip and cook for an additional 2-3 minutes until golden brown.
Remove the pancakes from the skillet and serve warm with your favorite toppings.
