Dulce de leche is a caramel made from sweetened condensed milk. If you prefer, use ready-made dulce de leche from delis and gourmet stores. The luscious multi-textured layers of this cake mean it will be a little bit messy to serve. Cut the cake using a finely serrated knife. Blowtorches are available from homeware and hardware stores. Alternatively, you can place the bananas under a hot grill to caramelise the sugar.
