There are desserts that satisfy a sweet tooth… and then there are desserts that feel like an experience. Crème brûlée belongs firmly in the second category. The crack of the caramelized top, the spoon breaking through into that silky custard underneath, the contrast between warm and cool—it’s not just dessert, it’s a moment.
When I first switched to keto, crème brûlée was one of those dishes I thought I had permanently lost. It’s built around sugar, cream, and patience—three things that felt intimidating to recreate without carbs. But the craving never really went away. Every time I saw it on a restaurant menu or in a cooking show, I missed that quiet luxury it brings.
So I set out to make a version that didn’t feel like a compromise.
This Keto Crème Brûlée keeps everything we love about the classic: rich vanilla aroma, custard so smooth it almost trembles, and that iconic crackly top. The difference? It’s low carb, sugar-free, and keto-friendly, without tasting “diet” in any way.
If you love elegant desserts, French classics, or simply want a keto treat that feels truly special, this recipe is for you.

My Personal Experience
The first time I tested keto crème brûlée, I’ll admit—I was nervous. Custards can be temperamental, and without sugar, there’s very little room for error. I remember standing in the kitchen, watching the ramekins bake gently in their water bath, hoping I hadn’t ruined perfectly good cream.
When they came out, they still jiggled slightly in the center—just like classic crème brûlée should. After chilling and torching the tops, I tapped my spoon against the surface.
That sound alone told me everything.
The custard underneath was smooth, rich, and deeply vanilla-scented. Not eggy. Not thin. Not artificial. It tasted like the real thing—because it essentially is, just without sugar.
Since then, this recipe has become my go-to when I want to impress without stress. It’s the dessert I make when I want keto to feel luxurious, not restrictive.
Required Equipment
Ramekins
You’ll need 4–6 small ramekins.
- Even-sized ramekins ensure uniform baking.
- Ceramic works best for gentle heat.
Baking Dish or Roasting Pan
Used to create a water bath.
- Keeps the custard silky.
- Prevents curdling or cracking.
Saucepan
For gently heating the cream.
- Avoid boiling—low and slow is key.
Whisk
Essential for blending eggs smoothly.
- Prevents streaks and uneven texture.
Fine Mesh Strainer
Optional but recommended.
- Ensures ultra-smooth custard.
Kitchen Torch
For caramelizing the top.
- Oven broiler can be used as a backup.
Ingredients & Substitutions
Full Ingredient List (4 servings)
- 2 cups heavy cream
- 4 large egg yolks
- ⅓ cup powdered keto sweetener
- 1 teaspoon vanilla extract
- Pinch of salt
For the Brûlée Topping
- 2–3 tablespoons granulated keto sweetener (allulose preferred)
Why Each Ingredient Matters
- Heavy cream – Creates the rich custard base.
- Egg yolks – Provide structure and silkiness.
- Powdered sweetener – Dissolves cleanly without grit.
- Vanilla extract – The soul of crème brûlée.
- Salt – Enhances sweetness and depth.
- Granulated sweetener – Needed for the crackly top.
Substitutions & Adjustments
- Sweetener: Allulose works best for caramelization. Monk fruit blends can work but won’t melt exactly like sugar.
- Dairy-free: Full-fat coconut cream can be used, though flavor will change.
- Vanilla bean: Replace extract with seeds from ½ vanilla bean for deeper flavor.
How to Make Keto Crème Brûlée
Step 1: Preheat and Prepare
Preheat your oven to 325°F (165°C). Arrange ramekins in a deep baking dish.
Step 2: Heat the Cream
In a saucepan, gently heat the heavy cream over medium-low heat until warm and steaming. Do not boil. Remove from heat and stir in vanilla and salt.
Step 3: Whisk the Yolks
In a bowl, whisk egg yolks and powdered sweetener until pale and slightly thickened.
Step 4: Temper the Eggs
Slowly pour warm cream into the yolks while whisking constantly. This prevents scrambling.
Step 5: Strain the Custard
Strain the mixture through a fine mesh strainer for extra smoothness.
Step 6: Fill and Bake
Pour custard into ramekins. Add hot water to the baking dish halfway up the sides of ramekins. Bake 35–40 minutes until edges are set and centers jiggle slightly.
Step 7: Chill
Remove ramekins and cool completely. Refrigerate for at least 4 hours, preferably overnight.
Step 8: Brûlée the Top
Sprinkle a thin, even layer of granulated keto sweetener on top. Torch until melted and crackly. Let set 1–2 minutes before serving.
Common Mistakes to Avoid
- Boiling the cream
- Overbaking the custard
- Skipping the water bath
- Using granulated sweetener inside the custard
- Torch held too close
Pro Tips for Best Results
- Always use powdered sweetener in the custard.
- Chill fully before brûléeing.
- Use allulose for best caramelization.
- Torch slowly for even browning.
- Slight jiggle means perfect doneness.
Keto Benefits of Eggs (Main Ingredient)
Egg yolks are a keto staple because they:
- Are low carb and nutrient-dense
- Add healthy fats
- Create natural thickening
- Support satiety and energy
They’re the backbone of classic custards—and keto-friendly by nature.

Keto Crème Brûlée Recipe
Ingredients
- Heavy cream – 2 cups 480 ml
- Egg yolks – 4 large
- Powdered keto sweetener – ⅓ cup
- Vanilla extract – 1 teaspoon
- Salt – 1 small pinch
- Granulated keto sweetener preferably allulose – 2–3 tablespoons
Instructions
- Pour the heavy cream into a saucepan and place it over medium-low heat. Add the vanilla extract and a small pinch of salt, then heat gently until the cream is warm and lightly steaming. Do not let it boil—small bubbles around the edges are fine. Once warm, remove the pan from the heat and let it sit for a minute.
- In a separate mixing bowl, add the egg yolks and powdered keto sweetener. Whisk them together until the mixture looks slightly pale and thicker, making sure the sweetener is fully dissolved and there are no grainy bits left.
- To temper the yolks, slowly pour a small amount of the warm cream into the egg mixture while whisking constantly. Continue adding the cream in a slow, steady stream, whisking the entire time. This gentle process warms the yolks gradually and prevents them from scrambling.
- Once all the cream is incorporated, strain the custard mixture through a fine mesh strainer into a clean bowl or measuring jug. This removes any tiny bits of cooked egg and ensures the custard will be perfectly smooth.
- Carefully pour the strained custard into ramekins, filling them evenly. Place the ramekins in a deep baking dish and pour hot water into the dish until it reaches about halfway up the sides of the ramekins. This water bath helps the custard bake gently and evenly.
- Transfer the baking dish to a preheated 325°F (165°C) oven and bake for 35–40 minutes, until the edges are set but the centers still have a slight jiggle when gently shaken. The custard will continue to firm up as it cools.
- Remove the ramekins from the water bath and allow them to cool at room temperature. Once cooled, cover and refrigerate for at least 4 hours, or preferably overnight, so the custard fully sets and chills.
- Just before serving, sprinkle a thin, even layer of granulated keto sweetener over the top of each chilled custard. Use a kitchen torch to melt and caramelize the sweetener until it forms a crisp, crackly crust. Let it harden for 1–2 minutes, then serve immediately and enjoy.
