Stir sugar and yeast to water. Keep aside for 5-10 minutes until frothy.In your stand mixer bowl, combine flour, sugar, condensed milk, softened butter, and the activated yeast.
With a spatula, bring together all ingredients till you have a scraggy condensed milk roll dough. Cover the dough and let it proof for 15 to 20 minutes.
When the condensed milk bread roll dough starts to leave the sides of the bowl, transfer it to a lightly greased bowl. Cover and place in a draft-free corner of your kitchen for an hour.
Punch the dough gently to deflate. Turn it over your work surface. You don’t need to flour the counter. Shape it into a log and cut equal pieces for 9 milk yeast rolls.
