Line a 9X9 inches baking pan with parchment paper covering all the side.
In a medium size microwave safe bowl, add the sweetened condensed milk and dark chocolate chips and stir together.
Microwave for 30 seconds and stir for about 15 seconds using a spatula.
Place back and microwave for another 30 seconds.
Stir for about a minute until the chocolate fudge mixture is well combined and smooth. The chocolate chips will finish melting during stirring.
If you notice the chocolate chips haven’t completely melted, microwave for additional 15 seconds and stir.
Transfer the fudge into the lined square pan and refrigerate for at least on hour.
Once chilled, remove from refrigerator and remove the fudge from the pan and cut into squares.
Serve and enjoy.
