Makes 9 muffins
Preheat oven to 350 degrees (F).
Grease a 12-cup muffin tin or line with paper liners.
Combine the flaxseed meal and water. Set the mixture aside to gel while preparing the remaining ingredients. (This makes a flax egg which is the vegan substitute for an egg.)
In a large bowl, whisk the remaining dry ingredients together (minus vanilla extract).
In a separate bowl, beat the pumpkin, milk, banana, and syrup together. Whisk in the wet flaxseed mixture and pour the wet ingredients into the dry. Stir to completely combine. Note: The batter will be thick but soft. It can still be stirred.
Fill each cup 3/4 of the way full. Add water to the 3 empty muffin holders. If desired, sprinkle the tops of the muffins with pumpkin seeds and quinoa flakes.
Bake on the center rack of the oven for 23 - 25 minutes. You should be able to insert a cake tester and have it come out clean.
Let muffins cool in pan for 5 minutes then transfer to a wire rack and cool completely.
