Directions
Step 1
In a small saucepan, combine the brown sugar, water, and cinnamon stick. Heat over medium heat, stirring until the sugar dissolves completely.
Step 2
Bring the mixture to a gentle simmer and cook for 3–5 minutes, stirring occasionally, until slightly syrupy.
Step 3
Remove the saucepan from the heat and stir in the vanilla extract. Let the syrup cool for about 15 minutes, then remove the cinnamon stick.
Step 4
Brew the coffee using your preferred method and allow it to cool. Refrigerate until chilled before assembling the drinks.
Step 5
Fill six tall serving glasses with approximately 1/2 cup of ice each.
Step 6
Pour 3/4 cup chilled coffee into each glass, followed by 1/2 cup milk and 1 tablespoon of the prepared cinnamon syrup.
Step 7
Stir gently until the coffee, milk, and syrup are well combined. Taste and add more syrup if you prefer a sweeter drink.
Step 8
Top with optional whipped cream, a light sprinkle of cinnamon, or an extra drizzle of syrup. Serve immediately.
Cook’s Notes
Use strongly brewed coffee or cold brew concentrate diluted to your preferred strength for a bold coffee flavor that won't disappear when ice is added.
Adjust the brown sugar cinnamon syrup according to your preferred sweetness. Start with one tablespoon per glass and add more if desired.
For a dairy-free version, replace regular milk with oat milk, almond milk, or another plant-based alternative.
Let the coffee cool before pouring it over ice to prevent excessive melting and dilution.
Store leftover cinnamon syrup in a clean airtight container in the refrigerator at 40°F (4°C) or below. For best quality, use within one week.
For extra cinnamon flavor, sprinkle a little ground cinnamon over the finished iced coffee.
