In a large bowl, mash the bananas.
Add the flour, baking powder, and milk. Stir until the batter is smooth.
Preheat your waffle maker according to the manufacturer's instructions.
Pour the batter into the waffle maker and cook until the waffles are golden and cooked through.
Let the waffles cool slightly, then cut them into rectangles or sticks.
In a shallow bowl, mix together the sugar and cinnamon.
Lightly spray both sides of each waffle with cooking spray.
Dip the waffles into the cinnamon sugar mixture until evenly coated.
For babies and younger toddlers, you can skip the cinnamon sugar coating and serve the waffles plain.
