Boil milk in a large pot.

Add sugar to it.

Mix the cinnamon powder, sultanas and almond flakes together into the milk.

Bring the milk to a boil again.

Break the baked puff pastry into small pieces.

Arrange it in a baking mould.

Pour the hot milk on the broken puff pastry.

Pipe the whipped cream on top of the puff pastry to cover the surface of the mould completely.

Bake for 15 minutes at 210 degrees Celsius.

When the cream turns brown on top, remove it from the oven and serve hot.
