Let’s get cooking! Here are the steps to create your own batch of Fluffy Cotton Candy Fudge:

1. Prepare a 9×9-inch baking dish by lining it with parchment paper, allowing the ends to hang over the sides for easy removal.
2. In a medium saucepan over medium heat, combine the granulated sugar, unsalted butter, and evaporated milk. Stir continuously until the mixture reaches a rolling boil.
3. Boil for 4-5 minutes, stirring constantly to prevent burning. This step is crucial for achieving the right texture, reminiscent of my grandmother’s careful watch over her simmering pots.
4. Remove from heat and quickly stir in the white chocolate chips and marshmallow fluff until smooth.
5. Add the vanilla extract, salt, and cotton candy flavoring, stirring until fully incorporated.
6. Divide the mixture into two bowls. Add blue food coloring to one bowl and pink food coloring to the other, stirring each until the color is consistent.
7. Pour the blue mixture into the prepared baking dish, spreading it evenly. Layer the pink mixture on top, gently swirling with a knife for a marbled effect.
8. Allow the fudge to cool at room temperature for 2-3 hours, or until set. For quicker results, you can refrigerate it for about an hour.
9. Once set, lift the fudge out of the pan using the parchment paper, and cut it into squares.
