Preheat the oven to 350° F and coat a 9×13 pan with cooking spray or line with parchment paper. Set aside.
In a large mixing bowl or stand mixer, add all dry ingredients (almond flour, coconut flour, baking soda, spices, and salt). Whisk well to combine. Add in remaining ingredients and mix well until smooth.
Fold in ¼ cup chocolate chips with a spatula if desired. Pour batter into the prepared pan. Sprinkle remaining ¼ cup chocolate chips over the top of the batter.
Bake for 30-35 minutes just until the edges turn golden brown. Remove from the oven and let cool slightly to room temperature before serving.
