Preheat the oven to 180C/350F. Line the muffin tins with cupcake wrappers.

In a bowl I first mixed the dry ingredients: flour, baking powder and salt.

In another bowl, first cream together the sugar and butter. To it add the mashed bananas, eggs,vanilla and the yogurt and mix together.

Slowly add the flour mixture to this and mix until combined. If you are adding chocolate chips, you can add it now, but its totally optional

I poured about 1/4 cup worth of battter into each muffin cup, and then baked for around 20 minutes. Allow it to cool before taking them out of the tin

Store the leftovers in an airtight container. I like them lightly warmed, maybe for around 20 seconds in the microwave and then spread a little butter ... yum! yum!
