Butterscotch Apple Crisp

6 cups sliced peeled tart apples (about 5 large)
3/4 cup packed brown sugar
1/2 cup all-purpose flour
1/2 cup quick-cooking oats
1 (3-1/2-ounce) package cook-and-serve butterscotch pudding mix
1 teaspoon ground cinnamon
1/2 cup cold butter or margarine
Vanilla ice cream -- optional

Place apples in a 3-qt. slow cooker.

In a bowl, combine the brown sugar, flour, oats, pudding mix and cinnamon.

Cut in butter until mixture resembles coarse crumbs. Sprinkle over the apples.

Cover and cook on low for 5 hours or until apples are tender. Serve with ice cream if desired.
