Italian Cream Stuffed Cannoncini

Start by preparing the custard cream (crema pastiera):

Warm up the milk until hot (not boiling).

In a medium-sized pan, whisk the egg yolks with the sugar, vanilla extract, and flour, until light and fluffy.

Add the milk some at a time while whisking, making sure there are no lumps.

Set the pan over mediocre heat and stir continuously until it reaches a slow boil. The cream will thicken, so be careful not to let it stick to the bottom. Lower the flame and cook for a couple of more minutes, until you reach the desired thickness.

Pour the cream into a glass bowl, cover with plastic wrap, and let it cool down. Chill for at least one hour.
