Ingredients You’ll Need
This Brown Sugar Iced Latte Recipe relies on a handful of simple but essential ingredients, each chosen to build layers of flavor, texture, and color. From the smooth espresso to the fragrant cinnamon and the creamy milk, every component plays a starring role in making this drink irresistible.
- Brown sugar (3/4 cup): Light brown sugar is recommended for its rich caramel notes that add depth to the syrup.
- Water (1 cup): Acts as the base to dissolve sugar and infuse the cinnamon for a warm aroma.
- Cinnamon stick (1) or ground cinnamon (1 teaspoon): Introduces a subtle spice that complements the sweetness beautifully.
- Vanilla extract (2 teaspoons): Pure vanilla is preferred for its natural sweetness and fragrant warmth.
- Espresso (3 shots): Freshly brewed for robust coffee flavor and essential caffeine kick.
- Oat milk (1 cup): Provides creamy texture and a gentle nutty undertone; can be substituted with whole or skim milk as desired.
- Ice cubes: Clear and hard cubes keep the drink chilled without diluting flavors too quickly.
- Ground cinnamon (2-3 dashes): For garnish and an extra layer of cinnamon flavor on top.
How to Make Brown Sugar Iced Latte Recipe
Step 1: Make the Brown Sugar Cinnamon Syrup
Begin by bringing water, brown sugar, and a cinnamon stick to a boil in a small pot. Keep it simmering gently for about 2 to 3 minutes until the sugar dissolves fully—the key is to stir continuously if needed. Once done, remove from heat and stir in the vanilla extract for that fragrant warmth. If you want to add your own twist, steep chai tea bags at this stage to introduce extra spices. After steeping, discard the tea bags and cinnamon stick, then allow the syrup to cool completely before using. This syrup can be stored in the refrigerator for up to two weeks, giving you a ready supply for many iced lattes to come.
Step 2: Shake the Espresso Mixture
Next, fill a shaker halfway with ice cubes and pour in the freshly brewed espresso. Add 2 to 4 tablespoons of the brown sugar syrup to customize the sweetness to your liking, followed by a couple dashes of ground cinnamon for that extra spice layer. Shake vigorously for about one minute until the mixture becomes frothy and well combined. Be cautious not to overfill the shaker to ensure you get a perfect mix without spills.
Step 3: Strain Into a Glass
Use a fine strainer to pour the shaken espresso mix into a tall glass brimming with fresh ice. Straining the drink is essential to avoid any chunks of ice or spices, giving your Brown Sugar Iced Latte Recipe a smooth, silky texture with every sip.
Step 4: Add the Milk and Garnish
Finally, gently pour one cup of oat milk or your preferred milk over the espresso mixture. Stir just slightly to allow the milk and coffee to swirl together, creating a beautiful marbled effect that’s as pleasing on the eyes as it is on the palate. Top with 2 to 3 dashes of ground cinnamon to finish with a fragrant touch that invites you to dive in.
How to Serve Brown Sugar Iced Latte Recipe

Garnishes
A sprinkle of ground cinnamon on top not only looks gorgeous but also enhances the warm spices in this drink. For something extra special, consider adding a light dusting of cocoa powder or placing a cinnamon stick alongside the glass for stirring. These small touches elevate the presentation and experience.
Side Dishes
This latte pairs wonderfully with lightly sweet pastries like croissants, cinnamon rolls, or biscotti. The subtle sweetness of these treats complements the brown sugar syrup perfectly while keeping the overall flavor profile balanced and inviting. Fresh fruit, especially berries or sliced apples, also makes for a fresh, crisp side that brightens the palate.
Creative Ways to Present
For a festive look, serve the Brown Sugar Iced Latte Recipe in clear glassware that shows off the gorgeous layering of milk and coffee. Add a reusable straw made of glass or stainless steel and a small saucer lined with chocolate shavings or cinnamon sticks for an extra cozy vibe. If hosting friends, serve it in individual mason jars decorated with twine for a rustic feel or use vintage teacups for a charming twist.
Make Ahead and Storage
Storing Leftovers
Any leftover brown sugar syrup can be stored in a sealed jar or bottle in the refrigerator for up to two weeks. This makes it easy to prepare your Brown Sugar Iced Latte Recipe on busy mornings without the need to remake syrup each time.
Freezing
While it’s not recommended to freeze the latte itself due to the milk content, you can freeze extra brown sugar syrup in ice cube trays. Once frozen, transfer the cubes to a baggie for easy use—just pop a cube or two into your espresso and milk for a quick twist on the recipe.
Reheating
If you prefer a warm latte, gently reheat your previously made Brown Sugar Iced Latte Recipe in a microwave-safe mug or on the stovetop until warm but not boiling. Stir well to maintain that lovely blend of flavors before enjoying.
FAQs
Can I use other types of milk in this recipe?
Absolutely! While oat milk adds a lovely creaminess and subtle nutty flavor, you can substitute it with whole milk, skim milk, almond milk, or even soy milk depending on your preference and dietary needs.
How strong should the espresso be?
Using three shots of freshly brewed espresso strikes a great balance between boldness and smoothness in this iced latte. However, feel free to adjust to your taste—add more for an extra kick or less for a gentler coffee flavor.
Is it necessary to shake the espresso and syrup mixture?
Shaking is key to melding the espresso with the syrup and achieving that delightful frothy texture. This method ensures an even sweetness throughout the drink and a luxurious mouthfeel.
Can I make this latte vegan?
Definitely! Simply use plant-based milk options like oat, almond, or soy milk along with pure vanilla extract to keep the drink completely vegan-friendly without sacrificing flavor.
What is the best way to store the brown sugar syrup?
Store the syrup in an airtight container or jar in the refrigerator. It stays fresh for up to two weeks and can be used not only for this latte but also for sweetening other beverages or desserts.
