It has four main elements. A biscuit base. followed with a layer of caramel ( the offee bit, as in toffee), then sliced banana , topped with whipped cream.
I grated some chocolate on the top, just to make it extra bad.
Luckily there were lots of people to share it with.
Easy to make, it can be done in stages. The biscuit base and caramel can be done the day before and quickly finished the next day.
