In a small bowl, add the flaxseeds, water, and apple sauce. Mix well to combine and allow the mixture to thicken for 5 minutes. This will act as a binder for the recipe, a substitute for eggs.
To a large bowl, add the cacao powder, brown sugar, vegetable oil, and vanilla extract. Mix well with a wooden spoon to combine. Pour in the flaxseed mixture, and mix again to form a dough.
In a medium bowl, mix the One Degree Organics Sprouted Whole Wheat Flour, baking powder, and salt. Then pour this dry mixture into the wet mixture. Stir well to combine all ingredients together into a thick and sticky dough. Cover bowl, and refrigerate for 4 hours or overnight.
Preheat the oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper. Place the powdered sugar onto a large plate, you'll need room to roll the cookies into the sugar.
Take a small scoop of cookie dough, about 1 tablespoon, and roll with the palm of your hands until it forms into a ball about 1-inch in diameter. Then roll that ball around in the powdered sugar until it is fully coated. Place the cookie ball on the baking sheet, and repeat. You should space the cookies 3-4 inches apart. My baking sheet held 12 cookies, which was half of the dough.
Bake cookies for 10-14 minutes, then remove baking sheet from oven and allow to cool before eating.
