Clean and rinse 3 to 4 large sweet potatoes. Place in a large saucepan or pot and cover with 1 inch of water. Bring to a boil and cook for 15-20 minutes, until sweet potatoes are tender and you can pierce them easily with a knife. Drain and cool. Once cooled, peel away the skins.
Preheat oven to 350 degrees. Grease a deep, lidded casserole dish with cooking spray. Mix Butter Buds into a sauce according to package directions.
Slice sweet into even pieces and make a layer of single slices in the dish. Cover with a layer of sliced apples. Sprinkle 1/3 of the raisins, 2 Tbs of Butter Buds sauce, and 1/3 of the maple syrup over the apples. Repeat layers until the casserole is full, finishing with the raisins, Butter Buds sauce, and maple syrup.
Cover dish with a lid and bake at 350 for 25-35 minutes, until apples are tender. Serves lots. Enjoy!
