A London Fog Tea Latte is a creamy latte with earl grey tea and oat milk with a touch of sweetness. It’s a delicious tea latte for a cozy drink! (Dairy-free, Vegan)

I'm not one to normally think of lattes as being anything but coffee. To be honest, I used to be a 100% tea-drinker only!
Little by little I've converted to a sole coffee drinker during the day, and tea at night. However, one day at Starbucks I decided to try one of their tea lattes - a London Fog Tea Latte to be exact. It was delicious!
So I decided while making my way through Starbucks drinks and first was to attempt a vegan London Fog Tea Latte! I also made my own version of a Pumpkin Chai Latte - what should be next?!
A London Fog Latte is actually really easy to make. You simmer oat milk and sugar in a small pot, while you steep earl grey tea bags in boiling water. Froth the milk and sugar mixture and then pour on top of the steeped earl grey tea!
It takes only a few minutes - definitely shorter than the ride to the Starbucks, waiting in the line, and getting back. And even better, you probably have all of the ingredients already at home!

What is a London Fog Tea Latte?
So what even is a London Fog Tea Latte? Well as crazy as it is to imagine, you can actually make lattes from non-coffee!
A London Tea Fog Latte is the same thing as an earl grey latte. It's slightly sweet, all the way creamy, and absolutely delicious! It consists of earl grey tea bags, hot water, oat milk (or non-dairy milk), and sweetener.
Ingredients & Substitutions

- Water
- Earl Grey Tea Bag - Substitute for your favorite black tea.
- Oat Milk - See below for notes on cleanest oat milk brands and how to choose. Substitute for almond milk or non-dairy milk (or dairy) of choice.
- Sweetener - Use maple syrup, honey or coconut sugar.
Optional: Add vanilla extract to add a little extra vanilla flavor. You can also use vanilla syrup.
Tea Bag vs. Loose Tea
It’s always easier to use an earl grey tea bag than loose tea. If you do use loose leaf tea, use a tea infuser.
Oat Milk in Lattes
This latte recipe uses oat milk, because I find it the closest substitute for dairy milk. Oat milk is typically thought of as the closest dairy milk option for lattes. Baristas often compare oat milk as being creamy and having a great ability to froth.
Barista versions of milks (there’s oat, hemp, soy, almond, macadamia, and more!) have popped up recently. This version has higher fat content and a few added ingredients so that it froths better and creamier.
An article on Tenderly outlines a summary of nine different non-dairy barista blends. The favorites from baristas are Oatly Barista Oat and Califia Barista Oat. My favorite clean brand for barista oat blends is Elmhurst.
Clean Oat Milk Brands
So, what is the cleanest oat milk brand? There are quite a few clean oat milks out there. Look for oat milks that have:
- Few ingredients (think: oats, water and salt - the fewer the better)
- No gums (like xanthan gum)
- No oils (like canola oil, rapeseed oil)
- Glyphosate* free oats or organic oats or gluten free oats
*Glyphosate (an ingredient in pesticides that is toxic to plants) is found in non-organic ingredients. Wheats and grains can have higher levels of glyphosate and are better if purchased as glyphosate free, organic or gluten free.
Is Oat Milk Gluten Free?
Oats are not intrinsically gluten free.
Oat milk can be sometimes contaminated with gluten as they are processed in facilities with gluten. If you are celiac or have a stronger gluten intolerance, look for gluten-free certified oats.
Look for glyphosate free oats or gluten-free certified oats.
Step-By-Step Instructions
Bring water to a boil in a tea kettle or pot.
In a small pot, warm the oat milk and bring to a boil. Once at a boil, add the maple syrup and stir together. Bring to a simmer and simmer for ~3 minutes.

While the milk and sugar mixture is simmering, pour the boiled water into your cup and add the earl grey tea bag. Allow to steep for 3-5 minutes. Make sure to not over-steep as it will get bitter.
Froth the oat milk and syrup mixture.

Remove the earl grey tea bag from your cup and pour the frothed oat milk and syrup mixture into the cup. Spoon the foam on top of the mixture.
Frequently Asked Questions
What if I don’t have a frother?
If you don’t have a frother, you can always use a stovetop method. Use a whisk back and forth while your oat milk is on the stove top in a small sauce pot. Whisk until the milk froths.
You can also use a French press!
