In the bowl of the blender or food processor, combine the flours, coconut sugar, potato starch, cocoa powder, cinnamon, baking powder, baking soda, salt and plant based milk.
Blend until very smooth, starting on low and gradually increasing to high, about 1 or 2 minutes in a high-speed blender and longer if needed. Add a dark chocolate and stir with a spatula. The batter should be fairly thin.
Heat the waffle iron, and cook according to the iron’s instructions, using about 1/2 cup batter.
Eat while hot with your choice of toppings, such as: coconut yoghurt, favorite jam, fresh fruits, nuts.
