Chocolate Banana Muffin

I made another chocolate and banana cake.This time is a muffin , but it's  more like a cupcake to me.It's a very soft and moist texture, not like muffin(dense texture). This recipe's from Sonia's blog ,she highly recommended this recipe, and I agreed with her, you should try this. It's easy to make.

2 tbsp cocoa powder
100 ml milk
1/2 cup chocolate chips ( I used 100 gm)
150 gm mashed banana
Some banana wedges( about 2 cm length), I omitted this

Method:
