Blend the Bloody Base:
In a blender, combine ice, milk, ice cream, chocolate syrup, vanilla syrup, and graham cracker crumbs. Blend until creamy.
Bloody Cup Swirl:
Use raspberry sauce to draw blood streaks inside the cup. Optional: use the back of a spoon to smear it unevenly for a slashed look.
Pour the Frappe:
Fill the cups slowly to preserve the raspberry streaks.
Build the Nightmare:
Top with whipped cream, drizzle chocolate and raspberry "blood" across the top, then scatter graham crumbs and toasted mini marshmallows.
Final Kill:
Garnish with horror-themed toppers — a candy machete or a sugar Freddy glove for the ultimate slasher showdown.
