Inspired by the famous British dessert, Sticky Toffee Pudding and a banana version of it that I developed, this dense mist cake s the perfect way to use those ripened, speckled bananas on your counter top. This cake does not have a typical cake texture; like a good sticky toffee pudding, it sort of collapses in your mouth to a dense, rich, caramel-y, luscious bite that is simply addictive.
