Prepare an 8x8-inch pan by lining it with aluminum foil or parchment paper.

Place white bark in a microwave-safe bowl. Microwave in 30-second intervals, stirring often, until bark is completely melted.

Add sweetened condensed milk and cotton candy flavoring.

Split your mixture into two bowls.

Add a small amount of blue food coloring gel to one bowl and pink to the other. The amount used will depend on the type of food coloring gel you are using.

Add scoops of each color randomly to your prepared pan.

Use a toothpick to swirl the colors together, creating a marbled look.

Refrigerate fudge for 2 hours or until it is hardened.

Cut into pieces and serve.
