Whisk all of the dry ingredients together until fully combined.
Combine the pumpkin, water, butter, and egg and mix into the dry ingredients.
Pour about 1/3 of a cup of batter onto each waffle square on your iron. Heat until cooked through and enjoy!
If you want to soak this recipe to get the benefits of easier to digest grains, you can:
Combine the flours, pumpkin, water, butter, and egg.
Add an acidic liquid by either completely replacing the water with homemade yogurt, or by reducing the water by 1/4 c. and add 1/4 c. of another acidic liquid (kefir, whey, lemon juice, buttermilk, or apple cider vinegar).
Let this batter soak for 12-24 hours. (The longer the better.)
When you are ready to make waffles, add the rest of the ingredients and cook as usual. These may take a bit longer to cook fully.
