Line a 13×9 inch pan with foil and spray with nonstick spray.

Combine sugar, butter, heavy cream and butter in a saucepan, cooking and stirring over low heat until the sugar is dissolved.

Once the sugar is dissolved, bring the contents to a boil while stirring for about 4 minutes. Remove from the heat and mix in the marshmallow creme and vanilla chips until all of the chips are melted.

Pour ¾ of the mixture into the foil-lined pan.

Add the cotton candy flavoring to the saucepan and stir until combined.

Drop or drizzle spoonfuls of the cotton candy mixture over the mixture already in the pan.

Add 2-3 drops of the pink food coloring in various areas on top of the fudge in the pan and then cut through the fudge with a butter knife to make the swirls.

Cover and allow to set in the refrigerator.

Remove the fudge from the pan by picking up with the foil and then cutting into squares.
