Preheat a griddle to 375° F or put a skillet over medium heat.
Begin by mashing bananas with a fork or potato masher. Add egg and mix until the egg is well incorporated.
Top wet ingredients with flour and baking powder, mix dry ingredients together then add milk.
Mix until combined. If you want to add any mix-ins, stir them in now.
Spread butter onto preheated griddle and pour 1/3 cup batter to form pancakes 1 inch apart.
Once bubbles start to form after 2-3 minutes, flip pancakes to cook on the second side for an additional 1-2 minutes or until cooked through.
Top with syrup, jam, or your favorite pancake toppings.
