Have you heard what’s all the rage these day’s over at you local Starbucks? Their popular iced brown sugar oat milk shaken espresso has been making waves across social media and beyond and there is a good reason why.
Because it’s incredibly delicious! While I love a good cup of hot black coffee or I may even indulge in this keto Irish coffee cocktail or this Keto Dalgona Affogato now and again, I do reserve a special place in my heart of the occasional iced latte style drink.
With only five recipe ingredients and tips for making this a sugar free, low carb, dairy free (plant based), and gluten free recipe, you can make the perfect keto copycat oat milk shaken espresso right at home!
Get all the tips, techniques, and substitutions listed below to recreate this drink for less money and less carbs too. Let’s dive in!
- Espresso Maker (can sub for strong brewed coffee, see more info below)
- Mason Jar (preferred) or Cocktail Shaker
- Measuring Spoons
- Milk Frother (optional)
Here is everything you need to know to make this inspired keto Starbucks drink at home.
- Espresso Shots – They are using the Starbucks blonde espresso blende in house, but I use whatever espresso I have on hand (usually this Lavazza is my go-to).
- Oat Milk – This has become easier and easier to find at most grocery stores as a dairy free alternative. I like to get a small carton from places like Trader’s Joes or Whole Foods because I don’t need to store it in the fridge until it’s opened. Not a fan of oat milk? Sub with almond milk (especially for a handful less carbs too).
- Low Carb Brown Sugar- There are so many options for low carb sweeteners on the market. While I would first encourage you to use what you like the best (everyone’s tastes are different), I do prefer this Sukrin Gold brand for a true flavor profile with little to no after taste.
- Cinnamon – We will use this to help flavor our brown sugar syrup in place of their cinnamon dolce style syrup. You can also buy their sugar free version of this or make your own homemade cinnamon keto simple syrup too!
- Hot Water – Obviously you need this for the espresso, but it will also help with dissolving our low carb sweetener to make our brown sugar style syrup.
How to make a homemade iced oat milk shaken espresso:
I like to first prep the brown sugar and cinnamon syrup before making my shots of espresso. I find this works best by building it into a glass mason jar because a metal shaker can get really hot to the touch.
In a glass jar add 3 tbsp. of very hot water. I use the hottest water that will come out of my sink or you can microwave some water for about 45-60 sec. Add the hot water to the jar then mix in the low carb brown sugar.
Because I eat a lower carb diet, I do not prefer my drinks (or any treats) to be too sweet. I prefer 3-4 tablespoons of the brown sugar in this recipe. Adjust as needed for your preference.
Next, add in about 1/4 tsp of cinnamon. I like a little and find a little really does go a long way. You can add a little more to the top for garnish to help amp up the cinnamon flavor.
Once everything is in the mason jar, give it a really good shake so the low carb sweetener dissolves. Pour in your 2 shots of espresso and shake again! Pour in your oat milk and ice and top it off with a sprinkle of cinnamon.
- 2 Shots Espresso
- 3 tbsp. Hot Water
- 3 tbsp. Low Carb Brown Sugar
- 1/4 tsp. Cinnamon (plus a little for garnish)
- 6 oz. Oat Milk
- In a mason jar, combine the hot water (I just use the hottest tap water I can get) and the low carb brown sugar and cinnamon together.
- Shake it well until the low carb sweeter has dissolved.
- Add the two shots of espresso to the jar and shake again.
- Pour your ice into a glass. Pour the espresso mixture over the ice and then top with the oat milk.
- Garnish with a little cinnamon if desired.
Don't have an espresso maker? Use instant espresso powder or really strong brewed coffee (4 oz.).
