Prepare Equipment: Line 8x8 inch pan with foil. Set aside rubber spatula for stirring.
Heat Ingredients: Add all ingredients to microwave-safe bowl. Microwave for 30-second intervals at 50% power until just melted, thoroughly stirring between intervals. Stir mixture until silky smooth, then pour into lined pan.
Chill & Serve: Freeze until fudge is set, about 1 hour. Lift up foil to remove fudge from pan, and cut into 16 bars. Serve cold and store any leftovers.
