Preheat a nonstick skillet or griddle over medium-low heat. Lightly grease it with butter or oil.
Peel one banana and place it into a blender along with the egg, ground cinnamon, vanilla extract, and baking powder.
Blend until the mixture is completely smooth and creamy.
Pour the blended mixture into a mixing bowl.
Add the all-purpose flour and whisk until a smooth batter forms without lumps.
Slice the remaining banana into thin, even coins.
Dip each banana slice into the batter, ensuring it is fully coated on all sides.
Carefully place the coated banana slices onto the preheated skillet.
Cook for about 2 to 3 minutes, or until bubbles begin to appear on the surface.
Flip each pancake bite and cook for another 2 minutes until both sides are lightly golden and fully cooked.
Remove the Banana Pancake Bites from the skillet and serve warm with your favorite toppings.
