Better-Than Starbucks Iced Brown Sugar Oat Milk Shaken Espresso

Making a Starbucks-style drink at home saves money and lets you control sweetness and strength.

It’s slightly sweet with a warm cinnamon note and a bold espresso punch.

What’s in an Iced Brown Sugar Oat Milk Shaken Espresso?

The recipe is straightforward: brown sugar simple syrup flavoured with cinnamon, freshly brewed espresso (or a strong coffee alternative), cold oat milk, and ice. The name really does describe the drink.

Brown Sugar Simple Syrup

The brown sugar simple syrup is the star of this drink. Simple syrup is made by dissolving sugar in water; using brown sugar gives a deeper, caramel-like flavor. For this version, we add a cinnamon stick and a pinch of salt to round out the taste.

1. Place 1 cup water, 1 cup packed dark brown sugar, 1 cinnamon stick, and 1/8 teaspoon salt in a small saucepan.
2. Bring to a simmer over medium-high heat, whisking until the sugar dissolves.
3. Reduce heat and simmer for 5–10 minutes to concentrate the flavor.
4. Remove from heat, let cool, discard the cinnamon stick, and store the syrup in an airtight container in the refrigerator for up to 5–7 days.

Espresso

Brew about 2 ounces (1/4 cup) of espresso for each serving. A Nespresso or other home espresso machine works well. If you don’t have espresso equipment, use a strong brewed coffee, instant espresso dissolved in a small amount of hot water, or a premade cold brew espresso concentrate.

Oat Milk

Oat milk is our preferred dairy-free option for this drink because it froths nicely and has a naturally creamy flavor. Use a barista-style oat milk if you want the creamiest result, or any unsweetened oat milk you prefer. The drink also adapts well to cow’s milk or other plant-based milks if needed.

How to Make an Iced Brown Sugar Oat Milk Shaken Espresso

Here’s a concise step-by-step to assemble the drink once your syrup and espresso are ready.

1. Make the brown sugar simple syrup and let it cool.
2. Fill a shaker or mason jar with 1/2 cup ice. Reserve another 1/2 cup ice in a serving glass.
3. Add 2 oz (1/4 cup) hot or cooled espresso and 2 tablespoons brown sugar simple syrup to the jar with ice. Cover and shake vigorously until well chilled and slightly frothy.
4. Pour the shaken espresso mixture over the ice in the serving glass.
5. Froth or shake 1/2 cup oat milk and pour it over the espresso. Stir gently to combine and enjoy.
