Preheat the oven to 350 degrees.
In a small bowl, stir together the flaxseed meal and water. Set aside to thicken while you’re preparing the other ingredients.
In a medium bowl, add the rolled oats, flour, cinnamon, nutmeg, and salt. Stir to combine.
In a large bowl, stir together the maple syrup, vanilla extract, coconut oil, and flaxseed meal mixture. Add the dry ingredients to the wet ingredients, and stir until the flour is incorporated. Stir in the raisins. If the dough is too sticky to handle, refrigerate it for 5 to 10 minutes.
Drop the dough in heaping tablespoon-sized portions on a baking sheet. Bake for 12 to 14 minutes, or until the cookies are set and lightly browned. Cool on a wire rack. (Yields 30 cookies)
