This is a recipe I have had for many years. I an not sure but I believe this recipe was cut from a ladies magazine advertisement for Borden's Eagle Brand Milk.
1 3/4 cups unsifted flour
1 cup quick cooking oats
1/2 cup firmly packed brown sugar
1/2 tsp baking soda
1/2 tsp salt
1 cup cold margarine or butter
1 cup chopped walnuts
20 caramels, unwrapped
1 (14-oz) can Borden's Eagle Brand Sweetened Condensed Milk
1 (21-oz) can apple pie filling
Preheat oven to 375 degrees. In large bowl, combine flour, oats, sugar, baking soda, and salt; cut in margarine until crumbly. Reserving 1 1/2 cups of crumb mixture, press remainder on bottom of 13x9-inch baking pan. Bake 15 minutes. Add walnuts to remaining crumb mixture. In a heavy saucepan, over low heat, melt caramels with milk; stirring until smooth. Spoon apple filling over prepared crust; top with caramel mixture then reserved crumb mixture. Bake 20 minutes or until set. Cool. Best served warm with ice cream!
