Preheat a waffle iron and grease liberally with cooking spray or coconut oil.
Place all the ingredients in a blender or food processor. Process on high until smooth. If the batter is runny, let it sit for 5 minutes to allow the oat flour to absorb the liquid.
Pour the batter into the waffle iron (mine comes with a measuring cup that I use to measure mine). Cook 3 minutes then flip and cook another 3 minutes until golden brown.
Pop the waffle out of the iron, grease and repeat until you have 4 large waffles. Divide the waffles into meal prep containers for breakfast.
Notes
Makes 4 large waffles. 1 serving equals 1/2 of a waffle.
