First things first, line an 8x8 inch or 9x5 inch pan with parchment paper, leaving some overhang on the sides. This is your best friend for getting the fudge out later!
Grab your black candy melts. Put them in a microwave-safe bowl and microwave them in 30-second intervals, stirring well after each interval, until they are completely melted and smooth. Be careful not to overheat them!
Now, add the entire tub of cream cheese frosting to the bowl with the melted black candy melts. Stir, stir, stir until the frosting and the melted candy are completely combined and you have a smooth, black mixture.
Pour this black fudge mixture into your prepared pan and spread it out evenly with a spatula.
Time for the red! Place the red candy melts in a separate microwave-safe bowl. Just like you did with the black, microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Once the red melts are smooth, use a spoon to dollop or drizzle the melted red candy over the black fudge layer in the pan. Don't be afraid to get creative with your patterns!
Using a toothpick or a knife, gently swirl the red into the black layer. Don't over-swirl, or you'll lose the distinct colors. Just a few passes are perfect to create that spooky, marbled effect.
Pop the pan into the refrigerator for at least 2-3 hours, or until the fudge is completely set and firm.
Once set, use the parchment paper overhang to lift the fudge out of the pan. Place it on a cutting board and cut it into small squares using a sharp knife. For extra clean cuts, you can run your knife under hot water and dry it before slicing.
And there you have it – spooky, delicious Vampire Fudge ready to sink your teeth into!
