Best Rolls Ever

My mom won the Idaho state fair with this roll recipe. This is the roll recipe of choice in our family.

2 cups milk
1 cup butter
1/2 cup sugar
2 Tbsp yeast
1/2 cup warm water
2 eggs
1/2 tsp vanilla
2 tsp salt
6 1/2 cups flour

Scald milk, butter, and sugar. Let cool. Mix yeast in warm water. Pour yeast mixture into milk mixture. Make sure the mixture is completely cool, and then add 2 beaten eggs and vanilla. Slowly add dry ingredients. Raise for at least 20 minutes (I usually let it rise 1 hour). Knead for 3 minutes. Roll out the rolls and let raise at least 10 minutes (I usually let it rise for another hour). Bake at 425 for 10 minutes. Rub butter across the tops right when you take them out of the oven to make them look golden brown.
