Recipe Prep: Line the bottom and sides of an 8-inch square pan with parchment paper.

1. Add the white chocolate chips and sweetened condensed milk (use a skinny spatula to scrape out every last drop) to a medium saucepan set over medium-low heat. Warm the mixture slowly, stirring often, until it’s melted and smooth. Be careful not to let it burn!
2. Stir in the vanilla extract and green food coloring. 
3. Transfer the Grinch fudge mixture to the prepared pan, and spread it into a smooth, even layer. Work quickly as the chocolate will begin to set as soon as you remove it from heat. While the fudge is still soft, press red candy hearts onto the surface. I put the hearts in 4 rows of 4, so that when I slice the Grinch dessert each square will have 1 heart. Put the pan into the fridge to chill for at least 2 hours, or until it’s firm and completely set.
4. Once the fudge has set, use the edges of the parchment paper to lift it out of the pan and onto a cutting board. Use a sharp, flat-bladed knife to cut it into squares. Arrange the Grinch treats on a platter. Serve and enjoy.
