Place the yeast and sugar in a small bowl. Pour warm water over the yeast mixture and let it sit for about 10 minutes.
Combine butter, sugar, milk, and salt into a large mixing bowl. When your yeast mixture is ready, add them together and mix.
If you are using a stand mixer put on your bread hook and then pour in 3 cups of flour. If you aren’t, knead it by hand. Then add in 1 cup of flour at a time and mix. When you get to 5 cups of flour in the bowl, add in ½ cup of flour at a time. Stop when the dough doesn't stick to the sides or your fingers.
Then cover the sides of the bowl with shortening and cover the bowl with a warm towel. Let it rise for about 1.5 hours). When it has risen over the bowl, punch it down and place on a floured surface.
Knead the dough for 2-3 minutes.
Cut dough into two pieces and place them into the proofing baskets.
Let the bread rise again in the proofing baskets, and when it looks like a good loaf of bread, place them into the loaf pans. Put them into the oven at 375 degrees for 25 minutes.
When you remove the bread from the oven, coat the top with butter. Wait about 5 minutes and remove it from the pan.
