Preheat oven to 350F. Line 2 cookie sheets with parchment paper. Mix together ground flax seeds and water and set aside for 15 minutes, creating a flax egg.
Combine oats, oat flour, coconut sugar, baking powder, baking soda, cinnamon and sea salt in a bow. Mix well.
In a small bowl, whisk together coconut or avocado oil, maple syrup, vanilla and flax egg. Add to dry ingredients, stirring until uniform dough forms. Add raisins.
Using spoon or cookie scoop, drop dough by spoonful onto parchment paper. Flatten into circles with a fork. Bake for 8 -10 minutes, until slightly browned. Remove from oven and cool. Makes approximately 24 cookies.
