Step 1

Line an 8-inch baking dish with parchment paper or aluminum foil, leaving some overhang for easy removal. Set aside.

Step 2

Add the chocolate chips, sweetened condensed milk, and butter to a large saucepan and place over medium heat. Stir continuously until the chocolate chips are fully melted and the mixture is smooth.

Step 3

Remove from the heat and scoop the mixture into the prepared baking dish. Spread around into one even layer.

Step 4

Refrigerate for at least 3 hours or until fully chilled and the fudge is firm. Remove from the pan using the overhang from the parchment paper or foil, slice the fudge into pieces, and enjoy.
