Butter a 23 x 10 cm (9 x 4-inch) loaf pan. Line with a strip of parchment paper.

In a large bowl, add the chocolate chips and butter. Melt in the microwave for about 1 to 2 minutes, stirring every 30 seconds. Keep stirring until the chocolate is completely melted.

Add the condensed milk and stir again until smooth.

Pour into the pan. Refrigerate for about 2 hours, until firm to the touch.

Removes the fudge from the pan and cut into squares.

Enjoy!
