This iced sugar-free vanilla latte with oat milk recipe is delicious. It is a cheaper, more flavorful version of the iced vanilla latte you pay for every day at your local coffee shop. 

This oat milk vanilla latte is easy to make. Plus, only 4 ingredients are needed to make a sugar-free iced vanilla latte. Oat milk, cold brew coffee or espresso, sugar-free vanilla syrup, and ice are all you need to make this refreshing drink. 

Can I Use Espresso Instead Of Cold Brew Coffee

I used cold brew coffee to make this iced sugar-free vanilla latte because I do not have an espresso machine. However, you can also use espresso to make this iced vanilla latte. You may have to add more vanilla syrup to the latte since espresso is very concentrated. 

Can I Use Regular Vanilla Syrup

I used sugar-free vanilla syrup to make this iced oat milk vanilla latte. Some people do not like sugar-free vanilla syrup because it can contain preservatives and chemicals. This is why I made my own sugar-free vanilla syrup to make this iced vanilla latte. Nevertheless, you can use regular vanilla syrup to make this latte. 

How Many Calories In An Iced Vanilla Latte With Oat Milk

It depends on the iced vanilla latte’s ingredients. Usually, vanilla iced lattes are high in calories and sugar because of the vanilla syrup. An Grande iced vanilla latte with oat milk from Starbucks has 203 calories.

However, this iced vanilla latte is made with sugar-free vanilla syrup. Each serving has 131 calories, including 24 grams of carbs and 19 grams of sugar.

Is An Iced Oat Latte Healthy

Whether an iced oat milk latte is healthy depends on how you look at it. On the one hand, because it’s made with oat milk, each iced oat milk vanilla latte has 131 calories and 24 grams of carbs, including 2 grams of fiber and 19 grams of sugar. If you subscribe to a low-carb diet, an iced vanilla latte with oat milk may not be the best option. 

On the other hand, compared to the iced vanilla lattes with oat milk you buy at your local coffee shop, which may contain up to 270 calories or more, this homemade iced oat milk vanilla latte is lower in calories.  

Is An Iced Oat Milk Latte Sweet

An iced oat milk vanilla latte is slightly sweet but not overly sweet. Oat milk has a mild flavor, so it really allows the coffee’s bold flavor to shine. 

Should I Froth The Oat Milk 

This iced oat milk vanilla latte does not call for frothing the oat milk. However, you can froth the oat milk if desired. 

You can use a hand-held frother to froth the oat milk before adding it to the vanilla latte. However, if you do not have a frother, pour oat milk into a jar, filling it 1/3 of the way full. Cover the oat milk and shake it for a few minutes until it is your desired consistency. 

You can also froth milk in the blender. To froth oat milk in a blender, pour enough oat milk into a blender for one latte and blend on high until it reaches your desired consistency.

Time-Saving Hack: 

If you want to make this iced vanilla coffee even faster, make the cold brew coffee or espresso beforehand. You can make the coffee the night before.

Store the coffee in a mason jar in the fridge. The coffee will last for 1-2 days, but I recommend drinking in 24 hours for the best flavor. In the morning, mix the coffee in a glass with the other ingredients, and you will have an iced vanilla latte made in less than 2 minutes. 

How To Store Iced Oat Milk Vanilla Latte

An iced oat milk vanilla latte is best served right away. However, if you cannot finish it, remove the ice cubes to prevent the latte from becoming watered down. Cover the iced oat milk vanilla latte and store it in the fridge for 24 hours.
