Mash the banana in a bowl until smooth.
Add milk, vanilla extract, and melted butter. Mix well.
In another bowl, combine flour, baking powder, baking soda, sugar, and salt.
Add dry ingredients to wet, mix gently — don’t overmix. Batter should be thick but pourable.
Heat a non-stick pan or griddle, grease lightly.
Pour 1/4 cup of batter, cook until bubbles form (about 2 mins), flip and cook the other side.
Repeat for remaining batter.
