Ingredients

Scale
  • 1 cup packed light brown sugar
  • 1 cup water
  • 1 cinnamon stick
  • 1/4 teaspoon flaky sea salt
  • 2 shots (about 2 ounces) freshly brewed espresso
  • 2 tablespoons brown sugar syrup
  • Ice cubes
  • 3/4 cup oat milk
  • Optional: 1/4 teaspoon vanilla extract
  • Optional: Cinnamon sprinkle for garnish

Instructions

  1. Make the brown sugar syrup: In a small saucepan, combine 1 cup packed light brown sugar, 1 cup water, 1 cinnamon stick, and 1/4 teaspoon flaky sea salt. Place over medium heat and stir until sugar dissolves (2-3 minutes). Bring to a gentle simmer, then reduce heat to low and simmer for 5 minutes, stirring occasionally. Remove from heat and let the cinnamon stick steep for 10 minutes. Remove cinnamon stick and let syrup cool completely. Transfer to a glass jar and refrigerate for up to 3 weeks.
  2. Brew your espresso: While syrup cools, brew 2 shots of espresso (about 2 ounces total) using an espresso machine, Moka pot, Aeropress, or French press. Keep espresso warm.
  3. Combine espresso and syrup in shaker: Add 2 tablespoons brown sugar syrup to a cocktail shaker or mason jar. Pour warm espresso over syrup and stir briefly to dissolve.
  4. Add ice and shake: Fill shaker halfway with ice cubes (about 1 cup). Secure lid tightly and shake vigorously for 15 seconds.
  5. Pour over fresh ice: Fill a serving glass with fresh ice cubes. Pour shaken espresso mixture over the ice.
  6. Add oat milk and stir: Pour 3/4 cup oat milk over the espresso. Stir gently 5-6 times with a long spoon or straw.
  7. Garnish and serve: Sprinkle with cinnamon if desired. Serve immediately.

Notes

The brown sugar syrup is the key to this recipe. Don’t skip the cinnamon stick and salt—they mimic Starbucks’ deep, molasses-like sweetness. Shake for exactly 15 seconds for the best froth. Use barista-style oat milk for creaminess. The syrup keeps in the fridge for up to 3 weeks.
