Mash the banana in a large mixing bowl. Stir in the vanilla.
Pour in the oats, the flour and the baking powder.
Pour 1 tsp oil on your frying pan and begin to heat over a medium heat.
Using a whisk, quickly whisk in the peanut butter, egg and milk until it forms a thick batter.
You will notice they puff up quickly. This is the chemical reaction with the raising agent.
Spoon 2 dollops of mixtures for each pancake and fry on the pan over a low to medium heat. (Remember these are not crepes and need a lower, slower heat to cook through).
Allow to cook for about 2/3 minutes on each side. When bubbles appear on the surface flip them over and cook for another 2 / minutes.
As you continue to cook these pancakes, keep the cooked ones warm in a low oven and serve as a stack.
Drizzle with maple syrup and serve a dollop of peanut butter and Nutella on the side.
