Beat the melted coconut oil and coconut sugar together. Add the vanilla extract and eggs, one at a time and mixing well after each addition. Continue stirring and add in the baking soda, cinnamon, nutmeg, and salt. Add the gluten-free flour and arrowroot flour and mix again. Stir in the oats and raisins.
Using a cookie scoop or spoon, drop onto a baking sheet about 2” apart. Bake for 10-12 minutes or until the edges are just beginning to turn brown. Remove the oven and cool on a wire rack. Leave the cookies on the baking sheet for 10 minutes before removing.
