Prepare your pan: Line an 8×8-inch square baking pan with parchment paper or lightly grease it with cooking spray. This will make it easier to lift the fudge out once it’s set.

Melt the white chocolate: In a medium saucepan over low heat, combine the white chocolate chips and sweetened condensed milk. Stir constantly until the chocolate is completely melted and the mixture is smooth. Be careful not to overheat, as white chocolate can burn quickly.

Add green food coloring: Once the mixture is smooth, add green food coloring a few drops at a time, stirring well until you reach your desired shade of green.

Pour into the pan: Pour the green fudge mixture into the prepared pan. Spread it out evenly using a spatula.

Chill to set: Refrigerate the fudge for at least 2 hours, or until firm and set. You can also place it in the freezer for about 1 hour if you’re in a hurry.

Cut and garnish: Once the fudge is fully set, remove it from the pan using the parchment paper, and cut it into small squares. Garnish each piece with a few red heart sprinkles for a festive touch.

Serve: Enjoy your Grinch Fudge immediately, or store it in an airtight container in the refrigerator for up to 2 weeks.
