In a large bowl, combine flour, baking powder, and salt.
In a separate bowl, whisk together mashed banana, butter, egg, buttermilk, brown sugar, and vanilla.
Add the wet ingredients to the dry and stir gently with a rubber spatula until just combined—don’t overmix.
Heat a griddle or large skillet over medium-low heat and grease with butter.
Drop about ⅓ cup batter per pancake onto the griddle, spreading slightly into even rounds.
Cook until edges are set and bubbles begin to form, then flip and cook the other side until golden and cooked through.
