1 (18 1/4 to 18 1/2 oz.) pkg. chocolate cake mix
1/3 c. vegetable oil
1 egg
1 c. chopped nuts
1 (14 oz.) can sweetened condensed milk
1 (6 oz.) pkg. chocolate chips
1 tsp. vanilla
Dash of salt

Preheat oven to 350 degrees. In large mixer bowl, beat cake mix, oil and egg on medium speed until crumbly. Add nuts. Reserving 1 1/2 cups crumbs, press remainder firmly on bottom of greased 13 x 9 inch pan.

In small saucepan, combine remaining ingredients. Over medium heat, cook and stir until chips melt. Pour evenly over prepared crust. Top with reserved crumb mixture. Bake 25 to 30 minutes or until bubbly. Cool. Cut into bars. Store loosely covered at room temperature.
