Peel sweet potatoes (if desired) and put into pan; add water to cover and heat to boil. Reduce heat and simmer for 20 minutes or until tender. Drain water from potatoes and let air dry. Heat oven to 350 degrees F. With potato masher, mash potatoes to get out lumps and add 1 T melted butter. Turn into greased casserole dish or pan and set aside. Mix crumbled bacon, dried cranberries, bread crumbs, 1 T melted butter, maple syrup, salt and pepper well. Add walnuts and mix. Spoon mixture over the sweet potatoes and bake uncovered for about 25-30 minutes, making sure to heat thoroughly and until golden brown.
