In a separate bowl, mix together the dry ingredients (almond flour, oat flour, baking powder, cinnamon and salt). Add dry ingredients to wet ingredients and fold in chocolate chips, mix batter well. Line a muffin tin with 10 muffin liners. Pour batter evenly into liners. Bake on 350F for 20-25 minutes. Allow muffins to cool. Enjoy!
