Yes, you can use condensed milk in bread recipes. Usually, when i am using condensed milk in other recipes that don't require a full can, i will set the leftover condensed milk aside and use it to make a loaf of bread. If i don't have enough of the condensed milk to fill 1. 2 cup, i just add some water until i have the full amount. This is one of the easy bread recipes i use to make a loaf of bread with condensed milk.
