Sise delle Monache or Tre Monti is a specialty from Guardiagrele in Chieti. It's a sponge cake that is filled with thick pastry cream. The dessert is made with eggs, sugar, flour, and starch, while the cream is made with milk, sugar, eggs, and lemon zest.

A pastry bag is needed to create three pyramids that are connected at the base. Once baked, the tops are cut off and filled with cream, then covered and sprinkled with icing sugar. The shape of this dessert is supposed to represent Mount Majella's three peaks, and it was later rebaptised by a local poet as nun's breasts.
