In a mixer bowl, mix yeast with brown sugar. Combine milk and melted butter together, test to make sure it is not too warm (I should warm to the touch but not hot, about 110 degrees) Add to yeast/sugar, stir, and let rest for 15 minutes. If mixture foams, it is proofed and you're good to go. Add oatmeal, molasses and beaten egg and mix well. Add 2 cups flour, salt and begin mixing, adding flour in 1/2 cup increments until a sticky dough ball forms. Scrape out onto lightly floured board, sprinkle with flour over the top, and knead briefly for a couple of minutes. Place into greased bowl, turn over, cover with plastic wrap and place in refrigerator overnight, not to exceed 24 hours. Remove from bowl onto lightly floured board, punch down and shape into loaf shape. Place in the center of bread pan, and place in a warm area. (I usually heat the oven to 200 degrees briefly, turn off the heat, and just place the bread in there) Leave the bread alone until it has come to room temperature and risen to twice it's size. Bake in 350 degree oven for 20 minutes, and then bake in 5 minute increments until the top is browned, and sounds hollow when tapped with your finger. Let cool before removing from bread pan.
