1 (18 1/4 or 18 1/2 oz.) pkg. chocolate cake mix
1/3 c. vegetable oil
1 egg
1 c. chopped nuts
1 (14 oz.) can Eagle Brand sweetened condensed milk (NOT evaporated milk)
1 (6 oz.) pkg. semi-sweet chocolate chips

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