First, dissolve the brewer's yeast in lukewarm milk, not too hot, please.
Put the flour, sugar, egg and salt in the bowl, mix: 1 min. speed 4.
Add the milk to the mixture: 30 sec. speed. 4.
Add the butter and chocolate chips, knead: 3 min. speed. dough mode.
At this point the mixture will be elastic, work it briefly with your hands and leave to rise covered in a place free of drafts until it doubles.
After rising, resume the dough and form small balls (not too big because they rise) and place them on a baking sheet lined with baking paper, cover them and let rise for an hour.
Before baking, brush the surface of each pangoccolo with a mix of water and milk.
Bake in a preheated oven at 170°C for about 10 minutes or until the surface turns golden. (the time depends on the size of the rolls, the small ones cook less than the big ones)
To make them softer, I brushed them with water and milk even after taking them out of the oven.
Allow to cool completely and serve... Buon appetito!
If you use granular brewer's yeast, just add it directly together with the milk and knead, without first dissolving it.
To prevent the chocolate chips from melting, I put them in the freezer for at least 1 hour before using them.:)
As sugar, I almost always use whole cane sugar, which gives a darker appearance to desserts. While for flour you can experiment as you like, I have often used type 2 as well.
*For those who are intolerant to dairy products, lactose-free or plant-based milk and butter can be used.
