Directions
- Bloom & chill. Whisk black cocoa into a small portion of warm coffee to fully dissolve; combine with the rest, then chill.
- Mix base. Add milk or oat milk, simple syrup gradually (aim for sugar >10%), vanilla if using, and the black-cocoa coffee.
- Load & program. Pour into HS3L (≤ ~2.3 L). Select Frappé or Slush.
- Freeze. Run until ribbons form (~15–35 min). If adding alcohol, fold in late—keep batch ABV ≤16%.
- Serve. Sugar-rim glasses (black), dust with a pinch of black cocoa. Optional: thin orange-peel twist.
Tips
Bitterness balance
Black cocoa is very dark; add 1–2 tsp regular cocoa for rounder chocolate notes if desired.
Dairy-free swaps
Oat milk or almond milk works well; barista-style options give better body.
Flow adjust
If too thick, add 20–40 ml (0.7–1.4 fl oz) cold coffee or milk; if runny, extend 3–5 minutes.
