Line a baking sheet with parchment paper and set aside.
In a small bowl, combine gluten-free flour, salt and baking soda. Set aside.
In a stand mixer with paddle, cream butter and both sugars on medium until light, fluffy and well-incorporated.

Keep mixer on lowest setting and add chocolate chips, or stir in by hand.
Add your toasted coconut (or almonds if using those alternatively). Stir until just combined.
Using spoon or small scoop (1 inch), form small balls of cookie dough and place on sheet, keeping an inch or two distance in between. Cookies will spread slightly.
Add to your pre-heated oven and cook for 9-11 minutes or until edges just start to become golden. These cookies will be light in color.
Remove from oven and let cool on cookie sheet for a few minutes before removing to a cooling rack.
