Oil or line three muffin pans. (This recipe yields about 36 muffins!)
In a large bowl, mix the first five ingredients. Combine the baking soda and applesauce and stir it into the creamed mixture. Gently stir in mashed bananas and blueberries.
Combine the gluten-free flour, xanthan gum, sea salt, ground flax seeds and coconut flakes. Gently fold into the wet ingredients until everything is well mixed.
Spoon the batter into muffin cups (fill them to the top!).
Bake muffins in a preheated oven until they are golden brown, approximately 18 to 20 minutes.
