Combine everything in a blender or food processor. Pulse or blend until mixture is completely combined and smooth. Allow the batter to rest at least 5 minutes before cooking.
Spray the waffle iron with non-stick spray. Use a 1/2 cup measuring cup to portion out batter into a waffle iron. Cook 2-3 minutes per waffle, until it is golden brown.
Carefully flip the waffle onto a plate and repeat step 2 until all batter is used.
Notes
Serve with sugar free maple syrup, berries, butter, or whipped cream. Store waffles in a ziplock bag in the refrigerator up to 1 week.
