Preheat oven to 350°F and grease three mini loaf pans (3.6 x 6.2 x 2.4 inches) and line bottom with parchment paper.
In a separate small bowl, combine almond flour, coconut flour, baking soda, salt, and cinnamon.
While mixer is on low speed, slowly add dry ingredients to wet ingredients until fully incorporated.
By hand, mix in chocolate chips (I used 1/4 cup because I like just a hint of chocolate, you're free to add 1/3 cup).
Alternatively you can use a cupcake pan and also bake for 30-35 minutes or a regular 8 1/2-by-4 1/2 inch loaf pan, however this may take up to 45 minutes but really depends on your oven (just watch carefully as almond flour can burn more easily than regular flour).
