1-Line the pan: Line an 8×8 inch baking pan with parchment paper, leaving overhang on the sides for easy removal later. This is a crucial step to ensure your fudge comes out perfectly. In the directions from our recipe summary, you can also use an 8×5 inch bread pan if you prefer thicker pieces.

2-Melt ingredients: Combine 4 cups of semi-sweet chocolate chips and 1 (14-ounce) can of sweetened condensed milk in a large microwave-safe mixing bowl. Heat it in the microwave for about 3 minutes, using 45-second intervals at 50% power. Stir after each interval until the mixture is fully melted, thick, and matte, just like the instructions say.

3-Transfer and set: Transfer the melted mixture to the prepared pan and smooth the surface using a rubber spatula or offset spatula. Cover the pan and let it sit for at least 2 hours until the fudge is fully set and firm.

4-Cut and serve: Lift the fudge out of the pan using the parchment paper and cut it into squares.
