Mix together the flour, baking powder, and salt in a small bowl.
In a separate, larger bowl (I used my stand mixer), mix together the vanilla extract, egg, buttermilk, oil, and the bananas. You can just stir until ingredients are combined, but I kept my mixer running until there were no banana chunks left.
Once your wet mixture is combined, add your dry mixture until everything is well incorporated.
Heat a large skillet or griddle to medium heat, lightly spray your skillet and use a 1/4 cup measuring cup or ice cream scoop to the batter into your skillet.
Wait 2-3 minutes or until you see little bubbles forming on your batter, flip pancake until other side is golden brown.
