Dairy Free Iced Coffee

Anyone who is still searching for a go-to coffee-based drink but doesn’t want to drink dairy will love this Iced Oatmilk Shaken Espresso recipe. Heck, even people who don’t mind milk should give this one a try.

Starbucks is known for creating some addictive beverages, and this one is a real winner.

Why This is the Best Iced Oat Milk Shaken Espresso Recipe

It’s the brown sugar spiced syrup that turns this ordinary iced latte into a must-try drink. The warmth of the cinnamon combines perfectly with the rich sweetness of the brown sugar and the hint of vanilla to soften out the harsh bitterness of the espresso.

The result is a smooth-drinking, sophisticated beverage that is not overly sweet or cloying.

Is this Starbucks Copycat Recipe Any Good?

It certainly is delicious and comes very close to what you would get if you ordered at Starbucks. Some people even think it is better.

Making this drink at home will save you a lot of money and let you tweak the recipe a bit to match your personal preferences.

Ingredient Substitutions

As written, this Starbucks Iced Brown Sugar Oatmilk Shaken Espresso recipe is fantastic, but that doesn’t mean you can’t switch things up a bit:

No Espresso Machine, No Problem!

Many people don’t have an espresso machine at home, but that doesn’t mean they have to skip this Starbucks copycat recipe. The most straightforward solution is to make this recipe using a premium coffee, like Veranda Blend from Starbucks, and double brewing it.

Or, you can try using an instant espresso. Medaglia D’Oro Espresso Style Instant Coffee and Café Bustelo Espresso Style Instant Coffee are outstanding choices.

The Double Cinnamon Quandary

Yep, this recipe calls for two types of cinnamon: cassia and Saigon. Believe it or not, there are a few pretty big differences between the two spices.

First off, cassia is not authentic cinnamon. Yes, the most popular ‘cinnamon’ in the US is imposter, but it tastes pretty much like the real thing, and many cooks actually prefer it to the real deal when cooking savory dishes.

Saigon cinnamon, on the other hand, is true cinnamon. It has a strong flavor and a bit of heat and is also much more expensive than cassia.

If you don’t want to run to the store just to make this drink, use whichever cinnamon you have on hand, but you may need to play with the amounts a little.

Regular Milk Instead of Oat Milk

Go ahead and use dairy milk instead of oat milk. Not everyone is into non-dairy milk, and that is totally fine. Use any kind of milk you want.

However, if you opt for oat milk, choose a brand that doesn’t have any extra flavoring or additional sweeteners. A very popular oat milk is the Barista Blend from Califia Farms.

How Much Caffeine is in this Drink?

With two shots of espresso, drinking an Iced Oatmilk Shaken Espresso provides plenty of caffeine to wake you up and keep you going.

While the actual caffeine level will vary based on the espresso you use, on average, a double espresso has about 150 mg of caffeine. A regular cup of coffee can range from about 65 mg to 175 mg of caffeine depending on beans, brewing method, and the serving size.

How to Store Homemade Simple Syrup

You can store the cinnamon brown sugar syrup in an airtight container in the fridge for up to two weeks. Note the spices may start to lose their pungency within a few days. For the best flavor, use it within 72 hours.

      Thank you for your comment. I could not find any evidence from Starbucks that the brown sugar syrup contained maple syrup. I can see some darker brown sugar having flavor notes similar to maple syrup though. Again, thank you for your thoughts.
