Recipe Highlights

  • Homemade Brown Sugar Syrup. The best part of this latte is the homemade brown sugar syrup. It is made by infusing brown sugar, vanilla, cinnamon and maple syrup together.
  • It takes 10 minutes to make. It’s so quick to make you can whip one together even on busy weekday mornings.
  • It’s a Starbucks copycat. If you like Starbucks’ iced brown sugar shaken oat milk espresso latte, this is a great copycat version. Plus it is so much cheaper to make it at home.
  • It’s vegan. This latte is vegan as is. There’s no need to make any substitutions.

Ingredients

Overhead view of the ingredients needed to make the oat milk latte.
  • Oat Milk: Use your favorite brand of oat milk. If possible, try to buy a “barista” version or one with a higher fat content. These types of oat milk will froth more easily.
  • Espresso: Lattes are made with espresso. Use freshly prepared espresso. If needed, you can substitute this with strong coffee.
  • Brown Sugar: Brown sugar is melted on a pan to make a liquid sugar syrup. Brown sugar, as opposed to granulated sugar, adds a rich caramel flavor that goes really well with oat milk.
  • Maple Syrup: Use real maple syrup rather than an artificial one. You can substitute this with honey if needed.
  • Cinnamon: A dash of cinnamon adds some flavor.
  • Vanilla Extract: A little bit of vanilla extract adds sweetness and complements the other flavors.

Equipment

  • A small pan to make the brown sugar syrup.
  • An electric frother to froth the oat milk.
  • A travel mug for taking iced coffee to go.

Instructions

Step 1: Heat the brown sugar, maple syrup, cinnamon, vanilla extract and 1 tablespoon of the fresh espresso in a pan over medium heat. Stir occasionally until the brown sugar has dissolved. 

Step 2: Add the syrup to a glass filled with ice.

How to Froth Oat Milk

There are a few ways to froth oat milk. Choose whichever way works best for you.

  • Electric Frother: An electric frother is the easiest and most effective way to froth oat milk. This will produce the best results over any other method. Add the oat milk to the frother and select the “cold froth” option.
  • Handheld Frother: A handheld frother is a decent alternative if you don’t have an electric frother. Submerge the handheld frother in the cold oat milk and froth for about 30 seconds until it increases in volume.
  • Blender: Add the oat milk to a blender and blend on high for 20 - 30 seconds until the volume increases. This will not produce the same quality foam as the above two methods.
  • Mason Jar: Add oat milk to a mason jar and shake vigorously for 30 seconds to a minute. As with the blender method, this will not produce as frothy foam as an electric mixer.

Make Ahead & Storage

  • Make Ahead: To save time, make the brown sugar syrup in advance and store it in a mason jar in the fridge for up to 5 days. You may need to rewarm it in the microwave for a few seconds if it has solidified.
  • Storage: If you have leftovers, remove any ice from the iced latte and store the leftover latte in an airtight container in the fridge for up to a couple days.

Expert Tips

  • Don’t boil the syrup. Heat the syrup enough to dissolve the sugar but don’t let it boil. Boiling the syrup will cause too much liquid to evaporate and leave you with a very sticky, thick syrup.
  • Clean your pan right away. Clean the pan you used to make the syrup in right away. If left to sit, the syrup can become very sticky and it makes cleaning dishes more difficult.
  • Use coffee ice cubes. If you like to drink your iced coffee slowly, freeze coffee ice cubes to use in your drink. This will prevent your drink from becoming watered down as the ice melts.

Variations

  • Pumpkin Spice: For a pumpkin spice version that’s perfect for fall, replace the cinnamon with 1 - 2 teaspoons of pumpkin spice.
  • Chocolate: For a chocolatey drink, add in a drizzle of dark chocolate syrup.

FAQ

Is this like Starbucks’ iced brown sugar oat milk shaken espresso?

Yes, this is a similar, copycat version.

Do I have to froth the oat milk?

No. If you prefer not to froth the oat milk, this drink will still taste delicious. However you may need to add slightly more oat milk to compensate for the smaller volume of milk.
