Mash your banana in a bowl using a potato masher or a fork. Add in your egg and whisk until combined.
Add in your melted butter, vanilla and milk and mix until well combined.
Add in your dry ingredients and mix well.
Add your oil to your pan and heat it on medium heat.
Once hot, pour in 1/4 cupful of batter and fry until bubbles form on the top and the bottom browns, about 2 minutes.
Fry for another 1-2 minutes. Transfer to a plate and fry the remaining batter.
Serve hot with some maple syrup and any other toppings.
