Step 1: Blend the Frappuccino

In a blender, combine milk, ice, mixed berry puree, vanilla syrup or white chocolate sauce, and ice cream or yogurt (if using).

Blend until smooth and creamy. Taste and adjust sweetness if needed.

Step 2: Prepare the Glass

Drizzle strawberry or raspberry syrup along the inside of a tall glass to create a "blood" effect.

Pour the berry frappuccino mixture into the prepared glass.

Step 3: Add Toppings

Top with a generous swirl of whipped cream.

Drizzle more strawberry or raspberry syrup over the whipped cream for a dramatic effect.

Sprinkle with chocolate shavings or crushed cookies to add a "wild" touch.
