Combine yeast, sugar, and water in a mixer. Let sit until foamy. Add remaining ingredients and knead until dough is soft and smooth. Let dough rise in a greased bowl until doubled in size. Divide dough into two portions and shape into loaves. Let loaves rise in greased loaf pans until doubled in size. Bake at 390 degrees F for 25-30 minutes until golden brown. Brush with melted butter and let cool before slicing.
