This easy, barista-inspired iced brown sugar cinnamon oatmilk latte combines homemade brown sugar cinnamon syrup, creamy oatmilk, and bold coffee for a cozy, dairy-free treat you can make at home in under 10 minutes. It’s sweet, spiced, and totally customizable for any occasion.

Ingredients

Scale
  • 1/4 cup (50g) light brown sugar (or dark brown sugar for richer taste)
  • 1/4 cup (60ml) water
  • 1/2 teaspoon ground cinnamon (plus more for garnish, optional)
  • 1/2 teaspoon vanilla extract (optional)
  • 1/2 cup (120ml) strong brewed coffee or 2 shots espresso (cold brew recommended)
  • 3/4 cup (180ml) oatmilk, chilled
  • Ice cubes (about 1 cup for a tall glass)

Instructions

  1. Add brown sugar, water, and ground cinnamon to a small saucepan.
  2. Set over medium heat and whisk until the sugar dissolves completely, about 2 minutes.
  3. Once the mixture starts to simmer, lower the heat and cook for another 2 minutes until slightly thickened. Do not boil hard.
  4. Remove from heat and stir in vanilla extract if using. Let syrup cool to room temperature.
  5. Prepare strong coffee, cold brew, or espresso. If using hot coffee, let it cool for 5 minutes or chill with ice.
  6. Fill a tall glass halfway with ice cubes.
  7. Pour 2-3 tablespoons of the cooled brown sugar cinnamon syrup over the ice.
  8. Add the brewed coffee or espresso.
  9. Top with chilled oatmilk. For extra froth, use a milk frother or shake oatmilk in a jar before pouring.
  10. Stir or shake gently to combine. Sprinkle a pinch of cinnamon on top for garnish, if desired.

Notes

For best results, use a barista blend oatmilk for extra creaminess and froth. Prep extra syrup and store in the fridge for up to a week. Adjust syrup amount to taste for sweetness. Coffee ice cubes prevent dilution. Garnish with cinnamon for a café-style finish. Substitute oatmilk with almond, soy, or coconut milk if desired. For a warm version, heat the coffee and oatmilk before assembling.
