There are a few factors that make these soft dinner rolls so irresistible! Fat in in the dough. Both the fat from the whole milk and butter preserve the freshness of these soft dinner rolls and keeps them soft for a days. The fat keeps the rolls from drying out! Butter brushed tops. The butter on the top of the dinner rolls also helps seal the rolls and keep them nice and soft. Baking close together. This lowers the amount of browned "crust" on the rolls, which yields an overall softer texture!
