Pre-heat griddle or skillet. Add small amount of butter to griddle/skillet, if necessary.
Add the dry ingredients into a large bowl (flour, baking powder, sugar, salt, and ground cinnamon) and give it a quick mix.
Next, add the wet ingredients into the flour mixture ( mashed banana, eggs, vanilla, milk, and vegetable oil). Mix thoroughly. There will be some small lumps, that is fine.
Toss in your chopped pecans and give it one last stir.
Pour about 1/4 cup batter onto heated griddle. Allow small air bubbles to form on top of batter before giving them a flip. Enjoy!
