My Favorite Roll Recipe

I was given this roll recipe from my friend Jenny Brand:

2 1/4 tsp instant yeast
3 Tbsp sugar
1 cup very warm water
1 egg
1 stick butter or margarine
1/4 cup powdered milk
1 tsp salt
4 cups flour

Mix together the yeast, sugar, and water. Add the egg, butter, powdered milk, salt, and 1 cup flour and mix until smooth. Then add the remaining flour until the dough is the proper consistency for rolls. Let the dough rest for 10 minutes. Knead once more then shape and place in a greased 9x13 cake pan. Let the rolls rise until double in size. Bake at 350 degrees for 8-11 minutes or until golden brown. Butter the top of the rolls when the come out of the oven.
