How to Make It
Line an 8-inch square baking dish with 2 pieces of parchment paper, allowing sides to drape over.
Combine chocolate chips and condensed milk in a microwavable bowl. Microwave at HIGH about 2 minutes, until melted and smooth, stopping every 30 seconds to stir.
Pour mixture into prepared dish, and chill at least 1 1/2 hours. Carefully lift fudge out of dish using sides of parchment paper as handles, and place on a cutting board. Cut into 16 squares.
