In a large bowl mix together the oats, sugar, coconut and chocolate chips.
Mash a banana until it is squidgy and soft.
In a small pan, melt together the butter and golden syrup and mix in the banana.
Leave the melted butter mixture to cool slightly and then mix into the oats. I was too impatient and my chocolate melted. Whoops! It still tasted good, but choc chips would have been nice.
Bake for 25 minutes. Take out near the end and test with your finger, it should be slightly springy if you want a chewy flapjack. Leave it in longer if you want a crisper flapjack.
