Pour sweetened condensed milk into an 20 cm pieplate. Cover pieplate with aluminum foil. Pour about 1 cm hot water in a larger shallow pan. Place covered pieplate in pan. Bake at 220ºC or 1 hour and 20 minutes or until condensed milk is thick and caramel colored (add hot water to pan as needed). Remove foil when done, and set aside. Cut bananas crosswise into 0 cm slices, and place on crust. Spread caramelized milk over bananas. Cool for at least 30 minutes. Beat whipping cream until foamy; gradually add powdered sugar, beating until soft peaks form. Spread over caramel layer. Sprinkle with crumbled candy. Chill at least 3 hours or overnight before ----
