Preheat oven to 350F and line baking sheet with parchment paper.
In a large bowl, mix together almond flour, coconut flour, baking soda, and salt.
In a small bowl, whisk together coconut oil, maple syrup, lemon juice, lemon zest and vanilla.
Add wet ingredients to dry ingredients and stir until combined.
Place in refrigerator to chill for 30 minutes. After 30 minutes, roll into balls and flatten slightly onto baking sheet. They won't spread much so form into desired shape.
Bake for 14-16 minutes or until golden brown.
Meanwhile, make the glaze by combining all of the ingredients. Once cookies have completely cooled, top with glaze.
Enjoy! Store on counter or in refrigerator.
