Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine almond flour, coconut flour, baking soda, and salt. Mix well.
In a separate bowl, whisk together maple syrup, melted coconut oil, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and stir until a dough forms. Fold in the chocolate chips.
Transfer the dough to the baking sheet and shape it into a log about 12 inches long and 3 inches wide.
Bake for 25-30 minutes until golden brown. Let cool for 10 minutes, then slice into 1/2-inch thick pieces.
Return the slices to the oven and bake for an additional 10-15 minutes until crisp. Let cool completely on a wire rack.
