In a large bowl, place the 1 1/2 cups of almond flour and 1/2 cup tapioca flour, or 1 2/3 cup almond flour and 1/4 cup coconut flour), salt, baking soda, and sugar, and whisk to combine well.
Create a well in the center of the dry ingredients. Add the butter, eggs, and vanilla and mix to combine.
Add the chocolate chips to the cookie dough, and mix until the chips are evenly distributed throughout the dough.
Both varieties of the dough will be soft but the almond flour/coconut flour combination will be softer than the almond flour/tapioca starch combination.
Chill the cookie dough.
Cover the mixing bowl with plastic wrap and place the cookie dough in the refrigerator for at least 1 hour, but up to a week or more if you don't want to bake all of the cookies at once.
When you are nearly ready to bake the cookies, preheat your oven to 325°F. Line rimmed baking sheets with unbleached parchment paper.
Shape the chilled cookie dough.
Remove the cookie dough from the refrigerator, remove the plastic wrap and using an ice cream scoop or two spoons, divide the dough into about 20 portions, each about 30 grams. Place about 2 inches apart from one another on the prepared baking sheets.
You can roll each piece of dough into a round between your palms, or leave it as is. The longer you chilled the dough, the easier it will be to shape into a round.
For the coconut flour variety, flatten each ball of dough into a 1/2-inch thick disk on the baking sheet after rolling into a ball. The coconut flour cookies will not spread as readily.
Bake the cookies.
Place the baking sheets, one at a time, in the center of the preheated oven and bake until lightly golden brown all over and mostly set toward the center (about 12 minutes).
Remove from the oven and allow to cool completely on the baking sheet (about 10 minutes). They will become more firm as they cool.
Store any leftovers in a sealed container in the refrigerator or freezer.
