Spray your waffle maker with cooking spray and heat on the highest setting.
In a large bowl, whisk the cottage cheese, egg, butter and milk until mixed.
In a separate bowl, whisk the oat flour, protein, baking powder and salt.
Add the dry ingredients into the wet ingredients and stir until combined *
Fill a lightly heaping 2/3 cup measuring cup with the batter and pour onto the griddle, spreading out slightly. Cook until desired level of crispiness has been achieved – I like mine at 2 cycles of the waffle maker.
If your batter has absorbed some of the moisture, add 1 Tbsp of milk and whisk before making the other waffle.
