Preheat the oven to 180 C/350 F.

Chop the pumpkin into thin slices. The thinner you’ll cut the pumpkin, the sooner they’ll soften.

Place the milk, the pumpkin slices, the sugar and the cinnamon stick in a pot and bring to boil, mixing every once in a while.

When the pumpkin will start to soften, add the amaretti biscuits and cook until the biscuits will dissolve. Remove the cinnamon stick.
