In a large bowl, pour about a teaspoon of melted butter and set aside.
In a medium bowl, sprinkle the yeast over the warm water and let stand for 5 minutes and the yeast gets foamy.
Add the remaining melted butter, sugar, salt, flour, and milk.
Stir everything together until it’s fairly smooth and the dough is tacky. Don’t worry if it’s sticky, you’ll add plenty of flour when you’re rolling out the dough.
Place the dough in the buttered bowl and roll it around to coat the dough with the butter. Cover tightly with plastic wrap and leave in a fairly warm, draft-free place to rise for 1 ½ hours and it’s doubled in size.
Punch down, cover again, refrigerate, and let it rise for another 1 ½ hours and it’s doubled in size (that's called "proofing").
