Ingredients

for 1 serving

  • 1 small (about 6 ounces) purple sweet potato
  • ⅔ cup whole milk
  • 1 tablespoon sweetened condensed milk
  • ½ teaspoon ground cinnamon
  • ice
  • 1 double-shot espresso, cooled
  • purple sweet potato powder, for garnish

White Chocolate Cold Foam

  • 3 tablespoons heavy cream
  • 1.5 tablespoons whole milk
  • 1 tablespoon white chocolate coffee syrup

Preparation

  1. Fill a pot with water to a depth of 1 inch, and bring to a simmer over medium-high heat. Place a steamer basket inside the pot. 2. Add the sweet potato; cover and steam until fork-tender, 15–20 minutes. Remove from heat.
  2. Remove the sweet potato from the steamer, and let cool for about 10 minutes. Peel off and discard the skin. Transfer the flesh to a blender. Add the whole milk, condensed milk, and cinnamon. Blend until smooth and creamy, 1–2 minutes.
  3. In a separate cup, make the cold foam: Froth together the heavy cream, milk, and white chocolate syrup until thick and foamy, 15–20 seconds.
  4. Assemble the drink: Pour the sweet potato mixture into a tall glass filled with ice. Add the espresso shot, then top with the cold foam mixture. Garnish with purple sweet potato powder, if desired.
  5. Enjoy!
