This butterbeer iced coffee is the easiest, best-tasting at-home version inspired by The Wizarding World of Harry Potter. A quick homemade butterbeer syrup and silky cold foam make this an instant fall favorite.

Ingredients

Butterbeer Syrup

  • 2 tablespoons brown sugar

  • 1 tablespoon butter

  • 1 tablespoon maple syrup

  • ½ teaspoon vanilla extract

  • Pinch of salt

Butterbeer Iced Coffee

  • 1–2 tablespoons Butterbeer Syrup

  • 1 cup cold brew or iced coffee

  • Ice

  • Splash of half-and-half (optional)

Butterbeer Cold Foam

  • ¼ cup heavy cream

  • 1 tablespoon Butterbeer Syrup

Instructions

  • Make the Butterbeer Syrup:
    Combine brown sugar, butter, maple syrup, vanilla, and salt in a small bowl. Microwave for 15–20 seconds, then stir until smooth and glossy.

  • Make the Cold Foam:
    In a measuring cup or jar, combine heavy cream and 1 tablespoon of the syrup. Froth or whisk for 20–30 seconds, until thick but still pourable.

  • Assemble:
    Add 1–2 tablespoons of syrup to a glass. Fill with ice and pour in the cold brew. Add a splash of half-and-half if you want a creamier base. Top with the butterbeer cold foam and serve immediately.

Notes

  • Leftover syrup keeps for 5 days in the fridge.

  • Add more syrup to the foam if you want a sweeter, richer topping.

  • Works with hot coffee too, but the butterbeer flavor shines best iced.
