You can, but reduce it on the stove with a little sugar and water to make a thicker, jam-like consistency for swirling.
Is this fudge super sweet?
Yes—white chocolate and condensed milk make a rich fudge. Cut into small squares and balance with tart fruit or salty snacks on the side.
Can I make this ahead?
Absolutely! Make it up to 3 days ahead and store in the fridge until ready to slice and serve.
Do I have to use food coloring?
Not at all! The jam alone will create a pinkish swirl, but for a more dramatic “bloody” look, a drop or two of red gel food coloring really helps.
Conclusion
Whether you’re throwing a haunted house bash, making party treats for kids, or just feeling festive, this Halloween Vampire Fudge is the ultimate sweet-and-spooky treat. It’s rich, creepy, and just scary enough to make everyone smile (and maybe shiver a little).
