Put in microwave bowl. Cook on high in microwave for 3 minutes. Remove and stir until completely melted. Pour into a buttered pan (pan size 13 x9 x 2 cake pan or 11 1/2 x 7 1/2 x 1 1/2 brownie pan) and let it cool. Cut into squares.
If you line pan with foil, don't butter pan. When fudge is cool dump out upside down, remove foil and cut into squares.
