Grandma's Caramel Brownies

60 light caramels (I usually use 35-40, so does Grandma)

1/2 cup evaporated milk

1 german chocolate cake mix

3/4 cup margarine, melted

1/3 cup evaporated milk

1 cup chopped nuts (optional, I've never used nuts)

1 cup semi-sweet chocolate chips

In a heavy saucepan, combine caramels and 1/2 cup evaporated milk. Stir until melted. Set aside. Grease and lightly flour 9x13 baking pan. In a large bowl, combine cake mix, melted butter 1/3 cup evaporated milk, and nuts. Press half of dough into pan. Bake at 350 for four minutes. Sprinkle chocolate chips over crust. Spread caramel mixture over chips. Crumble remaining dough over caramel. Return to oven and bake at 350 for 18-20 minutes. Cool slightly, then refrigerate 30 minutes or until caramel is firm. Cut into squares and serve.
