Not having oat flour, nor wanting to buy oat flour, old fashion oatmeal in high speed blender was blended until almost powder as we prefer a little bit of texture in the flour.
Scaled for Likability: Good
Not quite as tasty as the oatmeal pancakes and a little on the dense side, the waffles were not bad for a first attempt. The next time these are made, I will let the batter rest for 30 minutes as in the pancake recipe before baking. This will allow the oat to soften hopefully allowing the mixture to lighten when cooked. If not, another teaspoon of baking powder will be added. Can't wait to try them again.
