Remove the saucepan from heat and quickly stir in the semi-sweet chocolate chips. Stir vigorously until the chocolate chips are completely melted and the mixture is smooth.
Pour and Set:

Pour the fudge mixture into the prepared pan, spreading it evenly with a spatula.
Let the fudge cool at room temperature until set, or place it in the refrigerator for faster setting (about 1-2 hours).
Slice and Serve:

Once firm, cut the fudge into small squares and enjoy!
