Heat your waffle maker. Using a meat masher or fork, mash the banana in the bottom of the mixing bowl.
Mix the remaining ingredients in with the mashed banana and ensure it is smooth and mixed well
Spray heated waffle maker with nonstick spray, and pour just enough of the mixture onto the bottom plate so as not to spill out. Replace the top and cook until done.
Repeat with remaining waffle batter until all the mixture is used.
Keep waffles warm in a toaster or microwave oven. Any leftovers can be stored in the fridge and reheated in the microwave, toaster oven or air fryer.
