Combine in mixing bowl 1 cup flour, baking soda, salt, brown sugar and oats. Cut in butter until particles are fine. Reserve 1 cup of this mixture. Press remaining mixture into the bottom of a greased 8-inch square pan. Bake at 350 degrees for 10 minutes.
Combine caramels and cream in double boiler. Cook over boiling water until caramels melt. Blend in 2 tablespoons flour. Spread carefully over baked base.
Sprinkle with chocolate chips and then with reserved crumb mixture. Bake at 350 degrees for 12 to 15 minutes until delicately browned.
Notes
*If using Pillsbury's Best Self-Rising Flour, omit salt and baking soda. Quick trick: Combine 1/2 cup vanilla caramel sauce with 2 tablespoons flour and substitute for melted caramels and cream.
