Cut and use a fork to mash the bananas on a plate until the substance is relatively smooth then put it aside.
Mix the egg, milk and cooking oil well in a bowl with a balloon whisk, then put it aside.
In a separate large mixing bowl, combine the flour, sugar, salt, and baking powder gently with a silicon spatula.
Pour the egg-milk-cooking oil mixture into the flour mixture, stir well until blended.
Add the chocolate chips and mix until the chips are blended with the mixture.
Stir the mashed banana into the mixing bowl until combined but do not over mix.
Place the batter into muffin cups to around two thirds of each cup.
Bake at 175 degrees C for 50 to 60 minutes, or until you insert a toothpick into center of cake and it comes out clean.
Super simple, isn’t it? The bananas and chocolate chips add rich flavor to the cakes and surely you can’t stand to take a bite. Enjoy the delicious cakes!
