In a heavy 1-quart saucepan, mix 2 1/4 cups sugar, 1/4 cup butter, 3/4 cup evaporated milk, 1 cup (5 oz.) marshmallow creme. Cook and stir to a full all-over boil. Mixture will be bubbly on top. Boil and stir over medium heat for 5 minutes. Take off stove.

Stir in 6 oz. package semi-sweet chocolate pieces (1 cup) until melted. Stir in 1 cup broken nuts and pour into buttered 8 or 9-inch pan. Press nut halves on top, if desired. Cool thoroughly. Cut into about 30 pieces.
