Foolproof and impressive, this dessert is a symphony of softness. Inspired by two British favourites—banoffee pie and trifle—our recipe turns an inexpensive, everyday ingredient like bananas into something spectacular. Slices of sweet fruit peek through the glass, while pastry cream and whipped cream live it up with ladyfingers and dulce de leche. Keep the surface low enough to be covered for transport, and you’ve got a bowl in one.
