Preheat the oven to 400 degrees F.
Place the muffin paper cups into the muffin pan and spray with baking spray (To prevent the muffins from sticking).
In a bowl, peel and mashed bananas. Put the chocolates in a small bowl and cover it with flour and mix, this will prevent the chocolates from sinking in the bottom of the batter.
In a separate bowl, crack the eggs beat lightly, add oil, vanilla, and sugar. Mix with the mashed bananas
Sift flour, baking powder, baking soda, and cinnamon powder. Add to the bananas mixture.
Fold in the chocolates and mix. Pour into the spray muffin pan.
Bake in the preheated oven for about 15 minutes until it's done but don't over bake it.
Note: If you want it sweeter you can add more sugar also if you would like more chocolate you can use more than the quantity I used.
