1 3/4 c. unsifted flour
1/2 c. firmly packed brown sugar
1/2 tsp. salt
1 c. chopped California walnuts
1 (14 oz.) sweetened condensed milk
1 c. quick-cooking oats
1/2 tsp. baking soda
1 c. cold butter
20 caramels, unwrapped
1 (20 oz.) apple filling

Preheat oven to 375 degrees. In large bowl, combine flour, oats, sugar, baking soda and salt; cut in butter until crumbly. Reserving 1 1/2 cups crumb mixture, press remainder on bottom of 9x13 inch pan. Bake 15 minutes. Add nuts to reserved crumb mixture.

In saucepan, over low heat, melt caramels with sweetened condensed milk, stir until smooth. Spoon apple filling over prepared crust; top with caramel mixture, then reserve crumb mixture. Bake 20 minutes or until set. Cool. Serve warm with ice cream.
