To begin, preheat your oven to 350 and line two pans with parchment paper.
In a small mixing bowl, add your almond flour, coconut flour, baking soda and salt and stir them together well.
In a large mixing bowl, add your coconut oil and almond butter and use a hand mixer to beat them together till smooth. Add your coconut sugar and beat again till smooth. Lastly, add your egg, lemon zest, lemon juice and vanilla, and beat lightly till just combined.
Pour your dry ingredients into your wet ingredients and stir them together till well combined, forming a smooth cookie dough batter.
Using a small cookie scoop, scoop your cookie dough out onto your pans, evenly spread apart. Bake in the oven for 10-12 minutes, or till the edges and tops of the cookies are set.
Let cool, devour!
These cookies can be stored on the counter for 2-3 days, or up to a week in the fridge.
