Ingredients

Scale
  • 2 tablespoons (24g) brown sugar (light or dark)
  • 1/2 teaspoon (1g) ground cinnamon
  • 2 tablespoons (30ml) water
  • 2 shots espresso (about 2oz/60ml) or 1/2 cup (120ml) strong brewed coffee
  • 1 cup (240ml) chilled oat milk
  • Ice (enough to fill a tall glass, about 1 1/2 cups/180g)
  • 1/4 teaspoon (1ml) vanilla extract (optional)
  • Pinch of salt (optional)

Instructions

  1. Combine brown sugar, ground cinnamon, and water in a small saucepan.
  2. Heat over medium, stirring constantly, until the sugar dissolves completely (about 1-2 minutes). Alternatively, microwave in a bowl for 30 seconds and stir until dissolved.
  3. Brew 2 shots of espresso or 1/2 cup strong coffee using your preferred method.
  4. Fill a tall glass (16oz) with ice.
  5. Pour the brown sugar cinnamon syrup over the ice.
  6. Add the hot espresso or coffee directly on top. Stir well to blend.
  7. Add chilled oat milk and gently stir or shake until combined and creamy.
  8. If using, add vanilla extract and a pinch of salt.
  9. Taste and adjust sweetness or spice as desired.
  10. Top with a dusting of cinnamon, insert a straw, and serve immediately.

Notes

For best results, use barista-style oat milk and double-strength coffee if not using espresso. Make the syrup ahead for quick assembly. Use coffee ice cubes to prevent watering down. Adjust sweetness and spice to taste. For a hot version, skip the ice and use steamed oat milk.
