To a sauce pan, add your chocolate chips, condensed milk, butter, and vanilla.
Cook on medium heat, stirring continuously until melted and smooth. Pour in your dried cranberries and fold gently until evenly combined. Do not overheat and burn your chocolate.
Line your 8x8 dish with parchment paper and pour in the fudge, smoothing it out evenly.
Place in the fridge to set for 2 to 4 hours. Remove from the dish, peel off parchment paper, and slice into even squares.
Serve and enjoy. The perfect Christmas fudge for gifting.
