Mix the pancake mix, water, oil, and banana puree together.
Stir in the cinnamon and vanilla.
Heat the waffle iron. When hot, spray with cooking spray and pour batter into the waffle maker. For a Belgian waffle maker, pour about ¾ of a cup of waffle batter.
Cook waffles until the light indicates it is done.
Serve with freshly sliced bananas, maple syrup, and whipped cream.
