My 4 ingredient keto creme brulee is a creamy vanilla custard with a crispy caramelised "sugar" topping. This easy yet elegant classic dessert has only 5.5g net carbs per portion.

Crème brûlée is one of those French dessert recipes that are just magical. I love that moment when my spoon breaks that crunchy "sugar" layer!
I have been making this low carb creme brulee for many years. Basically, it is my sugar free custard recipe with a caramelised sweetener topping. The combination of fluffy creaminess and the crisp candied shell is quite irresistible!
My version is dairy-free, but you can use regular cream as well.
Also, there's no need to use a kitchen torch. I'll show you how to get that topping crisp by using the broiler. It's really simple.
Ingredients

You only need 4 ingredients to make this easy treat:
- Coconut cream - This is the firm part of a can of coconut milk. Sainsbury's own coconut cream worked well for me. It is similar to the Aroy D brand. Or, use heavy cream.
- Egg yolks - I used the yolks from large eggs. Save the egg whites to make an egg white omelette!
- Vanilla - The secret ingredient of the recipe is fresh vanilla bean. It gives the dessert the characteristic black flecks and really takes the flavor to the next level. You can replace it with a quality vanilla extract.
- Sweetener - I used 2 different sweeteners. For the custard, I chose a powdered erythritol monk fruit sweetener. For the topping, I chose a golden erythritol sweetener.
I recommend a brown or golden granulated erythritol to create the caramelized topping. Examples are Lakanto Gold (which is what I used), Sukrin Gold or Swerve Brown.
Erythritol doesn't brown like normal sugar but it does set hard to give you that nice crunchy shell. That's why a golden erythritol is perfect. You get the "browned sugar" look and the crisp shell!
It's the only keto sweetener type that can do this.

Instructions
Here are the basic steps to make a keto creme brulee. For detailed instructions, scroll down to the recipe card.
Equipment Needed
You will need either 5 x 5-ounce ramekins, 6 x 4-ounce ramekins or 4 x 6-ounce ramekins. I think the 5-ounce ramekins are the perfect size. Place them into a large casserole dish.
Method

STEP 1
Split the vanilla bean in half and scrape out the seeds.

STEP 2
Heat the coconut cream (or heavy cream) and the vanilla bean pod in a saucepan over a medium heat. Wait until the cream starts to simmer and the first bubbles appear. Do not boil!

STEP 3
Add the egg yolks and the powdered erythritol to the mixing bowl with the vanilla bean seeds. Blend with an electric mixer until the eggs are pale, frothy and double in size.
Slowly add the lukewarm coconut cream to the egg yolk mixture, whisking continuously.

STEP 4
Pour the mix into ramekins. Fill the casserole with boiled water that reaches halfway up the ramekin sides. (The hot water helps the custard bake evenly and prevents splitting.)
STEP 5
Bake the custard in the preheated oven until the top is golden and the centre retains a jiggle. Cool to room temperature, then chill in the fridge for a couple of hours or ideally overnight.
STEP 6
Before serving, sprinkle the tops with granulated erythritol. Heat the sweetener with a kitchen torch until it melts and bubbles. Allow to cool at room temperature to harden, or you can place them back in the fridge.
Katrin's Expert Tip
If you don't have a kitchen torch, melt the erythritol by placing the ramekins under the grill/broiler for a couple of minutes.
Preheat the oven well and use the highest or second highest oven shelf so the sweetener can melt as quickly as possible without softening the custard.
Chill the custard well beforehand and watch closely so the sweetener does not burn. This can happen very quickly if you don't pay attention!
Last but not least, don't touch the melted sweetener until it has hardened - it's HOT.

Variations
Add 1 teaspoon of Brandy or Grand Marnier to the custard mix for grown-up keto creme brûlées!
Recipe FAQs
I don't recommend that you use allulose for either the vanilla custard or the top. I tried and it makes the custard too soft and the burnt sugar layer does not re-crystallize well after melting. Allulose is perfect anywhere you need a soft result - such as my keto caramel.
Just like allulose, Bocha Sweet does not set hard like erythritol.
Yes, but it won't brown. You'll end up with a crisp shell, but it will be transparent.
Yes! Simply replace the coconut cream with heavy dairy cream. The recipe steps remain exactly the same.
Storage
Cover the ramekins with clingfilm and store them in the fridge for up to 3 days. Not suitable for freezing.

Recipe

Keto Creme Brulee
Equipment
- 5 x 5-ounce ramekins (alternatively, 6 x 4-ounce ramekins or 4 x 6-ounce ramekins)
Ingredients
- 2 cups / 500 ml coconut cream or heavy cream
- 5 egg yolks large
- ⅓ cup / 40g powdered erythritol
- 1 vanilla bean pods or 2 teaspoon vanilla extract
For Torching
- 2 tbsp Golden erythritol such as Swerve Brown or Lakanto Gold
Instructions
- Split the vanilla bean in half and scrape out the seeds.
- Heat the coconut cream (or dairy cream) and the vanilla bean pod in a saucepan over a medium heat. Wait until the cream starts to simmer and the first bubbles appear. Do not boil! Take off the heat and let it cool for 15 minutes. (If you are using vanilla extract instead of the vanilla bean, add it now.)
- Add the egg yolks and the powdered sweetener to the mixing bowl with the vanilla bean seeds. Blend with an electric mixer for 2-3 minutes until the eggs are pale, frothy and double the size.
- Slowly add the (lukewarm) cream to the egg yolk mix, whisking continuously with a balloon whisk.
- Heat the oven to 325F / 160C.
- Pour the custard into ramekins (just over ¾ full) and place the ramekins into a casserole dish. Fill the casserole with boiled water that reaches half-way up the ramekins. This helps the creme brûlées bake evenly and prevents splitting.
- Bake for about 40 minutes until the top is golden and the centre retains a bit of a jiggle. The custard firms up as it cools.
- Remove from the oven and cool to room temperature, then chill in the fridge for a couple of hours or overnight, until completely cold.
- Sprinkle the custard with golden erythritol and melt the sweetener with a kitchen torch.Alternatively, place the ramekins on the second highest or highest oven rack and broil for about 2 minutes or until the sweetener has melted and browned. Watch it closely because the sweetener can burn suddenly!Let the "sugar" topping harden for about 10 minutes (best in the fridge). Don't touch the sweetener until it has firmed up - you'll burn yourself!

Let me know how you get on with it! Would love to hear.
Ruth
I just love this recipe! I have done it so many times and use it as a dessert when having people at home and they also love it! Some times I put fresh red fruits chopped on top and it's just delicious. Thank you for this great treat.
Alicia Rule
Do you need to use golden sweetener for the top or can you use plain Erythritol?
Katrin Nürnberger
Plain and golden both works!
