1. Butter an 8"x8"x2" pan. Stir milk and chocolate chips in 2 quart casserole; add chocolate. Microwave, uncovered on high (100%) 1 minute; stir. Microwave until chocolate is melted and mixture can be stirred smooth, about 2 minutes longer.

2. Stir in vanilla and nuts. Spread mixture evenly in pan. Refrigerate until firm. Cut into 1" squares. That's how you make Double Chocolate Fudge.
