Mix all ingredients together and place in a Crock-Pot® slow cooker greased with butter. (or use a slow cooker liner greased with butter)
Cover; Cook on Low for 5 to 6 hours or High for 4 hours.
Dish into individual servings.
If desired, sprinkle with cinnamon or dried fruit for garnish.
Peel, core and slice apples. Place apple slices and cranberries in cp. Mix remaining ingredients in separate bowl and sprinkle over top of apple and cranberries. Place 4 or 5 paper towels over the top of the cp, place an object (I use a wooden spoon) across the top of the cp and set lid on top. This allows the steam to escape. Turn cp on high and cook for about 2 hours.
Lightly butter a 3 1/2-quart slow cooker/Crock Pot. Place cherry pie filling in the slow cooker/Crock Pot. Combine dry ingredients and mix well; cut in butter with a pastry cutter or fork. Sprinkle crumbs over the cherry pie filling. Cook for 5 hours on low.
