Ingredients (Serves 1)

For the Brown Sugar Syrup

*Only a small amount is used per serving. Refrigerate the remaining.*

½ cup (118 ml) water
½ cup (115 g) brown sugar
½ teaspoon vanilla extract
Small pinch of salt

For the Shaken Espresso

2 shots freshly brewed espresso
½ cup (118 ml) oat milk
2 teaspoons brown sugar syrup (adjust to taste)
2 cups ice (divided)

Step-by-Step Method

1. Make the Brown Sugar Syrup

In a small saucepan, combine water and brown sugar over medium heat. Stir until the sugar dissolves and the mixture gently simmers. Allow it to cook for several minutes until slightly thickened.

Remove from heat, stir in vanilla extract and a pinch of salt, and let cool completely before using.

Tip: Store extra syrup in the fridge for up to a week.

2. Brew the Espresso

Pull two fresh shots of espresso. Let them cool slightly for a few minutes so they don’t melt the ice instantly during shaking.

For best results, use a medium-dark roast with chocolate and caramel notes.

3. Shake for Texture

Add 1 cup of ice to a cocktail shaker (or a jar with a tight lid).

Pour in:

The espresso
Oat milk
Brown sugar syrup

Seal and shake vigorously for 20–30 seconds. The mixture should feel very cold and slightly frothy.

4. Serve

Fill a tall glass with the remaining ice.
Strain the shaken espresso mixture over the top.

The result? A chilled, lightly foamed iced oat espresso with rich brown sugar depth and creamy body.

Customisation Ideas

Add a dash of cinnamon for warmth
Swap vanilla for maple extract
Increase syrup for a sweeter version
Use barista-style oat milk for extra texture

Frequently Asked Questions

Can I use strong brewed coffee instead of espresso?

Yes, but the flavour will be lighter and less concentrated. If using coffee, brew it strong.

Why shake the espresso?

Shaking chills the coffee rapidly and creates micro-foam, giving the drink a smoother mouthfeel and café-style finish.

Can I make this ahead of time?

You can prepare the syrup in advance, but for best texture, shake the espresso fresh.
