In a mixing bowl, combine the almond flour, flaxseed, salt, and coconut sugar (the dry ingredients) and stir.
In a separate bowl, whisk together the egg, vanilla extract, and coconut oil (the wet ingredients).
Pour the wet ingredients into the bowl with the dry and stir well.
Add the chocolate chips and stir to combine.
Scoop the dough onto a baking sheet and form cookies with your hands - these cookies aren't like regular ones where they spread out - they keep their form going in the oven.
Bake for 7 to 9 minutes, or until cookies feel firm when poked and have browned around the edges (see note below).
Notes
I bake live at high elevation, so it took my cookies 12 minutes to bake. If you live at lower elevation, 7 to 9 minutes in the oven should work just fine.*Replace the coconut sugar with regular brown sugar if you'd like.
