Ingredients

Scale
  • 4 cups (960ml) strong brewed coffee or espresso
  • 1/4 cup (60ml) vanilla syrup
  • 1 cup (240ml) milk of choice (for serving)
  • 1/2 cup (120ml) heavy cream or full-fat coconut cream
  • 1 tablespoon (15ml) vanilla syrup (for foam)
  • 1 teaspoon culinary-grade matcha powder
  • 1 tablespoon (15ml) milk of choice (for matcha paste)
  • Black sanding sugar or black sprinkles (for garnish)
  • Gummy worms or plastic spider rings (for garnish)
  • Edible glitter or silver luster dust (optional)
  • Ice cubes (for serving cold)

Instructions

  1. Brew 4 cups of strong coffee or espresso. Stir in 1/4 cup vanilla syrup until dissolved. Set aside to cool slightly for iced version, or keep hot.
  2. In a small bowl, combine 1 teaspoon matcha powder with 1 tablespoon milk. Whisk until smooth and bright green paste forms.
  3. In a tall narrow jar or bowl, combine 1/2 cup heavy cream (or coconut cream), 1 tablespoon vanilla syrup, and the matcha paste. Use a handheld milk frother to whip until thick and frothy, about 30-60 seconds, until soft peaks form.
  4. Fill clear glass mugs or cauldron cups with ice (if serving cold). Pour sweetened coffee into each cup, filling about three-quarters full.
  5. Spoon or pour the green cold foam over the coffee, creating a thick layer on top.
  6. Garnish with black sanding sugar, gummy worms or plastic spider rings, and optional edible glitter.
  7. Arrange all toppings on a tray or serving board. Let guests assemble their own drinks.

Notes

For best results, use culinary-grade matcha (not ceremonial). Make matcha paste first to avoid lumps. Use cold cream for thicker foam. Do not overwhip. The cold foam can be made up to 30 minutes ahead and stored in the fridge; re-whip briefly before serving.
