In a medium-sized bowl combine flour, baking powder, salt, and cinnamon. Mix until thoroughly combined, making sure there are no clumps.
In a separate bowl, combine sugar, mashed bananas, egg, milk, vanilla, and oil. Fold the dry ingredients into the wet ingredients, careful not to overmix.
In a large skillet, melt 2 Tbsp of butter. Using a ¼ measuring cup, scoop pancake batter into skillet, being sure to leave space in between your pancakes.
Cook on medium heat and leave alone until bubbles start to form on top of your pancakes. This means they are ready to flip. Flip in a quick fluid motion and allow them to cook the rest of the way through.
Once all your pancakes are done, remove them from the heat. Add 2 more Tbsp of butter and cook your remaining batter.
Top with desired toppings. Serve, and enjoy friends!
