Caramel Cream Brownies

Makes 30 brownies.. Preheat oven to 350 degrees. Combine chocolate and butter, and melt over very low heat. Cool slightly. Whisk eggs until frothy, add sugar, vanilla, and salt. Beat on high speed for 5 minutes, until smooth. Stir in chocolate mixture, add flour and beat just until blended. Pour 1/3 to 1/2 brownie mix into a lightly greased 9x13 pan (cover bottom of pan) and bake 10 minutes at 350 degrees. Combine Caramel Creams, evaporated milk, and margarine, and stir frequently over med/low heat and remove from heat when smooth. Remove brownies from over, spread Caramel Cream mixture on top and sprinkle nuts on top. Cover with remaining brownie mix and bake additional 25 to 30 minutes at 350 degrees. Cool for at least 2 hours, in pan, at room temperature to set caramel.
