Preheat oven to 350°F.
Mix 1 tablespoon of flax meal with 3 tablespoons of water and set aside for 5-10 minutes, until a "yolky" consistency forms.
Melt the coconut oil in a saucepan over low heat.
Combine all the dry ingredients together in a bowl.
If making your own oat flour, combine 1/2 cup of oats in a food processor and process until a flour texture forms.
Add all wet ingredients together in a separate bowl and combine, including the flax egg.
Add wet ingredients to the dry ingredients bowl and combine.
Scoop cookie batter (I used a melon ball scoop) onto a lined baking sheet.
Press the cookie batter down with a fork or the palm of your hand, so the cookie is flat.
Bake in the oven for 10-12 minutes, then let cool for 5 minutes on the baking sheet.
Transfer cookies to a cooling rack and enjoy!
