So the recipe is actually a Karen Martini one which I found from this site. The pictures looked too good to pass over and I had some really ripe and black bananas to use up as well.
The results did not disappoint and I had to control myself before scarfing down the whole lot when I made it for brunch this morning. It was moist and tender and bursting with great banana flavour which was matched perfectly with the chocolate and coconut. I used my newly purchased silicone pan which is actually more suited for bar cookies or brownies. They still came out great and tasted awesome. Will definitely make these again.
