Put the sugar and yeast to the water or milk. Wait until bubbles appear.

In a bowl mix the flour, condensed milk and egg.

Pour in the yeast mixture. Little by little until while kneading it.

Don't add everything, because it may be too runny then it can't be shaped.

Knead until half dull.

Then add in the butter. Knead until dull.

Then put in a warm spot for 30 minutes. Cover with a damp cloth.

After 30 minutes, divide and shape as you wish.

Then let them rest for an hour.

Bake in the preheated oven 180°c for 30 minutes.
