Peel the banana and mash it with a fork.
You don't have to leave it in a very smooth puree, this fit brigadeiro will taste better if you leave some pieces of banana.
Place the mashed banana in a pan, add the powdered milk and cocoa and mix.
Take it to the fire and keep stirring until it releases from the bottom, at the point of rolling brigadier.
Turn off the heat, remove to a plate and wait to cool.
Roll up and sprinkle with grated coconut or serve it as a spoonful of brigadeiro.
Enjoy your food.
