I love this recipe because it is incredibly easy to prepare and does not require any complicated techniques. I just whisk everything together, pour it into ramekins, and let the oven do the work.
I also like that this custard is naturally low in carbs while still tasting like a classic homemade dessert. The texture turns out silky and rich, and I can enjoy it warm or chilled depending on what I am in the mood for.
Another reason I keep coming back to this recipe is that it is perfect for small servings. I can make four individual custards at once, which makes dessert feel a little more special and helps with portioning too.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
3 large eggs
2 cups heavy cream
1/4 cup allulose (or monk fruit sweetener)
1 tablespoon vanilla extract
Directions
I start by preheating the oven to 180C/350F. Then I grease four small ovenproof ramekins and place them inside a large baking dish.
In a mixing bowl, I whisk the eggs, heavy cream, sweetener, and vanilla extract until the mixture is completely smooth. After that, I divide the custard mixture evenly among the ramekins.
Next, I boil water and carefully pour it into the baking dish until the ramekins are sitting in about an inch of water. I like using this water bath because it helps the custard bake gently and keeps the texture soft and creamy.
I place the baking dish in the oven and bake the custards for about 30 minutes, until the tops are set. Once they are done, I remove them from the oven and enjoy them warm or let them cool completely before chilling them in the refrigerator.
Servings and timing
I get 4 servings from this recipe.
My total time is about 35 minutes. I usually spend around 5 minutes preparing the ingredients and about 30 minutes baking the custard.
Variations
I sometimes change the flavor a little depending on what I have on hand. A small pinch of cinnamon or nutmeg gives the custard a warmer taste that feels especially nice during colder months.
I also like adding a little lemon zest for a fresher flavor. When I want a deeper dessert taste, I sometimes stir in a bit of unsweetened cocoa powder to make a chocolate version.
If I want to dress it up before serving, I add a few berries on top after chilling. That gives it a little color and a nice contrast to the creamy texture.
Storage/reheating
I store any leftover custard covered in the refrigerator for up to 3 days. I like keeping each ramekin covered so the custard stays fresh and does not absorb other flavors from the fridge.
When I want to reheat it, I warm it gently for a short time rather than overheating it. I find that a few seconds at a time in the microwave works best. I can also enjoy it straight from the refrigerator when I want a cold and creamy dessert.
FAQs
Can I use a different keto sweetener?
I can use monk fruit sweetener or allulose in this recipe, and both work well. I just make sure the sweetener I use is one that measures similarly and blends smoothly into the custard mixture.
Why do I need a water bath?
I use a water bath because it helps the custard cook evenly and gently. This keeps the texture smooth and creamy instead of rubbery or overcooked.
How do I know when the custard is done?
I look for the top to be set while the center still has a slight softness. The custard will continue to firm up a bit as it cools.
Can I make this custard ahead of time?
I can absolutely make it ahead of time. I usually let it cool completely, then refrigerate it until I am ready to serve it.
Can I serve this custard cold?
I like serving it cold just as much as warm. After chilling, the custard becomes even more firm and creamy, which makes it a great make-ahead dessert.
Conclusion
This easy keto custard recipe is one of those desserts I keep in my rotation because it is simple, reliable, and delicious. I love how a few basic ingredients turn into a rich and elegant treat, and I also appreciate that it fits easily into a low-carb lifestyle. Whether I serve it warm from the oven or chilled from the fridge, I always end up with a smooth and satisfying dessert.

Ingredients
3 large eggs
2 cups heavy cream
1/4 cup allulose (or monk fruit sweetener)
1 tablespoon vanilla extract
Instructions
Preheat the oven to 180°C/350°F. Grease four 2- to 3-inch ovenproof ramekins and place them in a large baking dish.
In a large mixing bowl, whisk together the eggs, heavy cream, allulose, and vanilla extract until smooth and fully combined.
Divide the custard mixture evenly among the four prepared ramekins.
Boil a kettle or bring 2 to 4 cups of water to a boil. Carefully pour enough hot water into the baking dish so the ramekins sit in about 1 inch of water.
Transfer the baking dish to the oven and bake for about 30 minutes, or until the tops are set.
Remove from the oven and serve warm, or let the custards cool completely. Refrigerate until chilled if desired.
Notes
For best texture, avoid overbaking the custard. The center should be just set.
Allulose and monk fruit sweetener both work well in this recipe for a sugar-free option.
Chill before serving for a firmer, more traditional custard texture.
