Preheat the oven to 350F (180C). In a small bowl, mix the ground flax seeds with the water. Set aside.
In another bowl, mix the flours, the baking powder, the spices and the salt. Set aside.
In a mixing bowl, cream the coconut oil, the apple sauce, the molasses and the coconut sugar with a whip. Add flax seed mixture.
Incorporate dry ingredients to the wet ones and mix with a spoon (the dough should be pretty thick, don’t over mix).
With a tablespoon, form 12 equal balls and place them on a baking sheet covered with a silicone baking mat (or oiled), leaving some space between them. Gently press each ball with a fork. If you want, roll each ball in a bit of sugar before placing it on the sheet. Bake in the oven for about 8 minutes, the cookies should be soft, so don’t overcook them!
