Preheat oven to 350 degrees, and line two cookie sheets with parchment paper.
In a large bowl, cream the buttery spread and sugars until light and fluffy
Add the flax egg and vanilla and continue to mix. Add 1/8 cup non-dairy milk.
Add the gluten free flour, baking soda, and 1/2 teaspoon salt. Mix until combined.
Stop the mixer and stir in the oats, chocolate chips, and seeds or nuts. If the dough is too dry at this point, add a little more liquid. Every gluten free flour acts a little differently, so if the dough seems crumbly, add a splash more non-dairy milk.
Sprinkle cookies with coarse sea salt.
*Look for certified gluten free oats to be sure they are gluten free!
Nutrition facts are for one large cookie.
