Preheat your oven to 180c and line or grease a 12 whole muffin pan.

In a large bowl mash your bananas well.

Add in the oil, vanilla essence, egg and milk.

Add all your dry ingredients into a bowl and mix lightly with a whisk until smooth and just combined.

Chop your chocolate into chunks.

Throw in your chocolate and fold in gently until the chocolate is well dispersed through the mixture.

Spoon your mixture to the top of each muffin whole.

Place in the oven for 15-20 mins or until a skewer comes out clean.

Let the muffins cool in the pan.

Once cooled gently remove. Store in an airtight container.
