Preheat your oven to 350°F (175°C). Grease or line an 8-inch cake pan.
In a large bowl, mix almond flour, oat flour, baking soda, and salt.
Add nut butter, maple syrup, applesauce, and vanilla extract. Stir until a thick dough forms.
Fold in the chocolate chips.
Press the dough evenly into the prepared pan.
Bake for 18–22 minutes or until golden around the edges.
Let cool completely before slicing. Enjoy!
