Line an 8-inch square baking dish with parchment paper, allowing it to overhang slightly for easy removal later.

In a microwave-safe bowl, combine the white chocolate chips and sweetened condensed milk. Microwave in 30-second bursts, stirring in between until smooth.

Add food coloring to the melted mixture, stirring until evenly blended.

Pour the mixture into the prepared pan and spread it evenly using a spatula.

Let the fudge sit at room temperature for about 30 minutes to cool and thicken.

Cover with plastic wrap and refrigerate for at least 2 hours until firm.

Lift the fudge from the baking dish using the parchment paper and cut it into squares.

Arrange the squares on a platter or in a gift box for sharing.
