What you will need
This recipe uses 8 simple ingredients that you can find at any grocery store:
- 3 shots espresso
- 3 tbsp brown sugar
- 3 tbsp water
- 0.5 tsp ground cinnamon
- 1 cup oat milk
- 1.5 cups ice
- 1 pinch flaky sea salt
- 0.25 tsp vanilla extract
Step by step instructions
Step 1: Make the Brown Sugar Cinnamon Syrup
Combine brown sugar, water, ground cinnamon, and vanilla extract in a small saucepan over medium heat. Stir until the sugar fully dissolves, about 3 to 4 minutes. Remove from heat and let cool for 5 minutes.
Step 2: Brew the Espresso
Brew 3 shots of espresso. Pour the hot espresso directly into a cocktail shaker or mason jar with a lid while it is still hot so it absorbs the flavors of the syrup when combined.
Step 3: Shake the Espresso
Add the brown sugar cinnamon syrup and a generous handful of ice to the shaker with the espresso. Seal tightly and shake vigorously for 15 to 20 seconds until the outside of the shaker feels very cold and the mixture is frothy.
Step 4: Build the Drink
Fill a tall glass with fresh ice. Strain the shaken espresso mixture over the ice in the glass. The espresso should look frothy and slightly aerated from the shaking process.
Step 5: Top and Garnish
Pour the cold oat milk gently over the shaken espresso to fill the glass. Finish with a pinch of flaky sea salt and a dusting of ground cinnamon on top. Serve immediately without stirring for the best visual effect.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- oat milk → almond milk for a nuttier lighter finish
- brown sugar → coconut sugar for a deeper caramel flavor
- espresso shots → 2 cups of strong cold brew concentrate
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Not shaking long enough which results in a flat drink without the signature frothy top
- Adding oat milk before straining the espresso which breaks the layered visual effect
- Using too little ice in the shaker so the espresso does not chill and dilute to the right strength
