Step 1

Line an 8x8 or 9x9 square pan with foil, extending the sides of the foil over the edges of the pan. Grease the foil with some cooking spray; set aside.

Step 2

In a medium heavy bottomed saucepan, add in the granulated sugar, marshmallow creme, evaporated milk, salt, and butter and bring to a boil over medium heat. Boil, stirring constantly for 5 minutes. Remove from the heat and stir in the white chocolate chips and vanilla extract until smooth and combined. Fold in the cranberries.

Step 3

Pour the hot fudge mixture into the prepared pan and spread into an even layer. Refrigerate for at least 2 hours to set before cutting into squares.
