A warm cup of tea can feel like a hug on a cold day. But when you mix the rich flavor of Earl Grey with a creamy, vanilla twist, you get something special. That’s exactly what a London Fog is. And the good news? You can make a keto-friendly version without all the sugar.
If you’re following a low-carb lifestyle, regular tea lattes can be a problem because of the sugar in traditional vanilla syrup and the milk. But with a few easy swaps, you can enjoy this cozy drink while keeping carbs low.
This Keto London Fog Tea has the same creamy texture, the same comforting vanilla aroma, and the same slightly floral hint of bergamot from the Earl Grey tea—just without the extra sugar or carbs. Whether you need a morning pick-me-up or an afternoon treat, this is the perfect way to sip something warm without breaking ketosis.
What Is a London Fog Tea?
A London Fog is a classic tea latte made with:
- Earl Grey tea (black tea infused with bergamot oil)
- Steamed milk
- Vanilla syrup
- A touch of sweetener
The vanilla and bergamot blend together beautifully, giving it a slightly citrusy, floral, and creamy taste. It’s a popular choice in coffee shops, but most versions are loaded with sugar.
For a keto version, we make a few changes:
✔️ Use unsweetened almond milk or heavy cream instead of regular milk
✔️ Swap the syrup for a sugar-free vanilla extract and keto-friendly sweetener
✔️ Stick to pure Earl Grey tea—no added flavors or fillers
Why You’ll Love This Keto London Fog Tea
- Low in carbs – Perfect for staying in ketosis
- Sugar-free – No syrups or artificial junk
- Rich & creamy – Feels indulgent but fits your diet
- Easy to make – No fancy equipment needed
If you love tea but want something with a little more flavor and a luxurious feel, this is for you. It’s also a great alternative to coffee if you’re looking to cut back on caffeine but still want something warm and comforting.
Keto London Fog Tea Ingredients
You only need a handful of simple ingredients:
1. Earl Grey Tea
This is the heart of the drink. Earl Grey is a black tea infused with bergamot oil, which gives it a slightly citrusy and floral taste. Make sure you’re using pure tea without added sweeteners.
2. Hot Water
You’ll need just-boiled water to steep the tea properly. Too hot, and it can turn bitter. Too cool, and it won’t extract enough flavor. The ideal range is 190–200°F (just below boiling).
3. Unsweetened Almond Milk or Heavy Cream
Milk is what gives the tea its latte-like texture. But regular milk has too many carbs, so we swap it out for:
- Unsweetened almond milk (low in carbs, light, slightly nutty)
- Heavy cream (richer, creamier, ultra-low in carbs)
- Or a mix of both if you want a middle-ground texture
4. Sugar-Free Vanilla Extract
Traditional London Fogs use vanilla syrup, but that’s full of sugar. Instead, we use pure vanilla extract (make sure it’s sugar-free) for the same flavor without the carbs.
5. Keto-Friendly Sweetener
Earl Grey has a natural bitterness, so a little sweetness helps balance it. Use:
- Stevia
- Monk fruit
- Erythritol
- Allulose
Liquid sweeteners mix in smoothly, but powdered versions work too.
6. Optional: Collagen or MCT Oil
For extra creaminess and a keto boost, add a scoop of collagen powder or MCT oil. This makes the tea more filling and gives it a bit of frothiness.
How to Make Keto London Fog Tea
Step 1: Brew the Tea
- Heat 1 cup of water to about 190–200°F (just under boiling).
- Add 1 Earl Grey tea bag (or 1 teaspoon of loose-leaf tea in an infuser).
- Let it steep for 3–5 minutes. The longer it steeps, the stronger the flavor.
Step 2: Heat the Milk
- In a small saucepan, warm ½ cup of unsweetened almond milk (or heavy cream).
- Keep the heat low—don’t let it boil. If you have a frother, use it to create a foamy texture.
Step 3: Add Vanilla & Sweetener
- Stir ½ teaspoon of vanilla extract into the tea.
- Add your sweetener of choice, starting with ½ teaspoon and adjusting to taste.
Step 4: Mix & Serve
- Pour the warm milk into the tea, stirring as you go.
- If using a frother, give it a quick blend to make it extra creamy.
- Taste and adjust sweetness if needed.
And just like that, your keto-friendly London Fog is ready to enjoy!
Variations & Tips
Make It Dairy-Free
Use coconut milk or almond milk instead of heavy cream for a fully dairy-free version.
Add More Flavor
Want an extra flavor boost? Try adding:
- A pinch of cinnamon for warmth
- A drop of lavender extract for a floral twist
- A little sea salt to balance the sweetness
Turn It Into an Iced Keto London Fog
- Brew the tea as usual and let it cool.
- Add cold almond milk and vanilla.
- Pour over ice and stir well.
- Use a hand frother for a creamy texture.
Bulletproof Version
Blend in MCT oil or grass-fed butter for a keto energy boost. This turns your tea into a filling, frothy treat.
Why This Works for Keto
Regular London Fog tea lattes are packed with sugar and carbs from vanilla syrup and milk. This version keeps things keto by swapping out:
- Milk → Unsweetened almond milk or heavy cream
- Vanilla syrup → Sugar-free vanilla extract
- Sugar → Keto-friendly sweetener
This way, you get the same great taste with none of the carb overload.
