In a large bowl, mix together all of the dry ingredients.
In a medium bowl, mix maple syrup, apple sauce, molasses, coconut oil and flax egg.
Add the wet ingredients into the dry ingredients and stir until combined.
Pat into a circle and cover with plastic wrap. Let refrigerate for about 30 minutes to an hour to make it easier to work with.
Preheat oven to 350F. Roll the dough into 1/2 inch thickness. Cut out with cookie cutters and arrange on a baking sheet lined with parchment paper.
Bake for 13-15 minutes, until lightly browned on the sides. Let cool on a wire rack.
Dust with powdered sugar, frost with royal icing or leave plain, as desired.
