Directions

1. Prepare an 8x8 pan by lining it with aluminum foil and spraying the foil with nonstick cooking spray.
2. In a large microwave-safe bowl, combine the chocolate chips, condensed milk, and butter. Microwave in one-minute increments until melted, about 2-3 minutes.
3. Stir to ensure all the chocolate is melted, then add the vanilla and salt. Stir until the candy is smooth and well-mixed.
4. Pour the fudge into the prepared pan and smooth it into an even layer.
5. Place the fudge in the refrigerator to set for at least 2 hours. Once set, cut into 1-inch squares and serve at room temperature. Store excess fudge in an airtight container in the refrigerator.
