Preheat Oven to 180-200C
Pop 8 muffin/large cupcake cases in a deep muffin tin
Mash the banana
Mix with the chocolate chips
Mix in all the other ingredients into all combined and no lumps of flour (I used a mixer but can easily be done by hand)
Split evenly between the 8 muffin cases and pop in the oven for 20 minutes
Keep an eye on it for the last few minutes just in case the cook a little fast
The muffins should rise a little and go a light golden brown on top
Remove from oven when cooked, pop on a cooling rack for a few minutes to coo (if you can wait that long!)
Eat and enjoy!
