Panettones are available in shops, we got ourselves 2 and ate one already, well ahead of Christmas. Vergani cafe panettone with chocolate chips. Not very sweet and light and fluffy, the cafe brioche is delicious, like especially the hard crust with some icing sugar at the side contrasts with the moist cake. The 2 of us finished it in less than a day!

@Bookwich has posted a NYT recipe if anybody wants to bake one.
