In a large mixing bowl, combine the mashed bananas, milk, vanilla extract, and egg if using.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients into the wet mixture. Stir gently until just combined. Avoid overmixing to keep the pancake bites fluffy.
Heat a non-stick skillet over medium heat and lightly grease if needed.
Spoon small portions of batter onto the skillet to create mini pancakes.
Cook the Fluffy Banana Pancake Bites until bubbles appear on the surface and the edges begin to set.
Flip carefully and cook the other side until golden brown.
Serve warm with maple syrup, sliced bananas, berries, or nut butter.
