Caramel Bars

(You have asked for the literary-hour bars. The recipe is from an old Woman's Day magazine. They are pretty good!)

2 1/3 cups all-purpose flour (Reserve 1/3 cup flour for caramel topping.)
2 c. old-fashioned oats
1 cup packed brown sugar
1/4 tsp. salt
1 tsp. baking soda
1 cup butter, melted
2 cups (12 oz.) semi-sweet chocolate chips (or morsels)
1 1/2 cup chopped walnuts
1 cup (12.25 oz jar) caramel topping

Combine 2 cups flour, oats, sugar, soda and salt. Stir in melted butter.
Reserve 1 cup of mixture for topping. Press the remaining into ungreased 13" x 9" pan.
Bake for approximately 15 min. at 350 degrees.
Sprinkle with chocolate and walnuts.
Combine caramel topping and 1/3 cup flour. Drizzle over base.
Sprinkle with reserved crumb mixture.
Bake additional 20 minutes at 250 degrees.
