Whisk together the almond flour, tapioca flour, flaxseed meal, baking soda, and salt in a medium bowl. Set aside.
Whisk together the butter and coconut sugar in a large bowl, and then whisk in the maple syrup, egg, vanilla, and vinegar.
Stir the dry ingredients into the wet, and fold in the chocolate chips and chopped nuts.
Cover the bowl with plastic wrap and chill 8 hours (or overnight).
Preheat the oven to 365F. Line 2 large baking trays with silpat baking mats or parchment paper.
Use a 1.5-tablespoon scoop to measure the dough, roll it into balls, and arrange the dough balls on the prepared baking trays.
Bake until the cookies are golden and set along the outside, about 10 minutes, rotating the trays once halfway through. Remove from the oven and sprinkle on the flaky salt.
Cool slightly so they stiffen a little and serve warm.
Notes
Chocolate Chips: You can use whatever brand of paleo friendly or vegan friendly chocolate chips you like.
Butter: You can use ghee or coconut oil instead of butter if you’re a paleo purist.
Storage: Store these cookies in an airtight container at room temperature for up to 3 days. Or layer them between pieces of parchment paper in an airtight container and freeze for up to 3 months.
Dairy Free Version: Simply omit the butter and instead use an equal amount of coconut oil or vegan butter.
Vegan Version: 1) Omit the butter, and use an equal amount of coconut oil or vegan butter. 2) Instead of the egg, use a flax egg. Simply mix 1 tablespoon golden flaxeed meal with 3 tablespoons water in a small bowl and let it sit for 5 minutes before using. (You will still need to add the 2 tablespoons of flaxseed meal to the dry ingredients like the recipe calls for.) 3)Make sure your chocolate chips are vegan. Enjoy Life is one of my favorite brands of vegan chocolate chips, and it’s available on Amazon.
