Keto Custard Recipe
When it comes to classic keto desserts, my favorites to make are chocolate pudding, chocolate mousse, and this easy keto egg custard.
Growing up, my mom never really got onto the baking trend. While other moms were making muffins and cookies every week, mine would be making more traditional desserts. Every weekend, my sister and I would look forward to various fruit crumbles, fruit pies, or the occasional fudge pudding cake (my downfall!). However, it was always the accompanying side dish that made me swoon- her egg custard.
I’ve been wanting to share a keto egg custard recipe for quite some time now. I never knew how simple it was to make my mom’s classic custard using low carb ingredients. Essentially, all I had to do was experiment with some different keto sweeteners to find one was best!
The texture is smooth, thick, and creamy, and the taaste is sweet and with a hint of vanilla, with NO eggy flavor whatsosever.
While many often serve custard as a sauce or side to some sticky pudding or a molten lava cake, I love how this recipe is baked, making it a perfectly portioned dessert! I served this at a dinner a few weeks ago and NO ONE could tell that it was made without any sugar or thickeners- it tasted like any good custard out there!
How do you make a keto egg custard?
- Eggs– Room temperature eggs, so the baking time is even.
- Heavy cream– Also known as double cream or thickened cream. Like the eggs, it’s best for this to be room temperature.
- Granulated sweetener of choice– Either monk fruit sweetener or erythritol can be used.
- Salt– Just a pinch to bring out the sweetness.
- Vanilla extract– Gives a light vanilla flavor.
In a large mixing bowl, whisk your eggs well, so the whites and yolks are well mixed. Add in the rest of your ingredients and whisk very well, until smooth and combined. Now, carefully distribute the custard mixture amongst 4 large ramekins and place them in a large baking dish.
Now, fill a kettle with water and bring to a boil. Once boiled, pour the boiling water into the baking dish, until an inch of water remains. Place the baking dish in the oven and bake the custard for around 30 minutes, or until the center is done. Remove from the oven and let cool slightly, or allow to cool completely, if you’d prefer a thicker and cooled custard.
Tips to make the best low carb custard
- Your custard mixture should be smooth before you pour it into ramekins. If you’d like to be extra cautious, feel free to use a stick or hand mixer.
- Feel free to add your favorite spices or extracts, like cinnamon or rose water.
- Serve custard with a scoop of vanilla ice cream or coconut ice cream for a fancy keto dessert.
Storing and freezing custard
- To store: Custard should always be stored in the refrigerator, in a sealed container. It will keep fresh for up to 2 weeks. I recommend you let it sit at room temperature for 30 minutes before serving.
- To freeze: Place individual portions of custard in freezer friendly containers and store in the freezer for up to 6 months. Thaw them overnight in the refrigerator before eating.

I never thought I could ever make anything that would ever go into a ramekin. I had them but thought, “please…I cannot use these things” so I kept them tucked away back in the cupboard. This was so easy to make and I never had custard made from scratch so this was just perfect all around. Flavor is just right; texture is so smooth and creamy. Gave some to my father who is LOVING all the desserts I am getting from this website since he is diabetic and needs to lose weight without losing his sweet tooth. Used monk fruit for sweetener. How do I get those things sticking out of the custard that you have in your pics????
Recipe calls for 8″ ramekins. Is that correct?
Apologies- it is 8cm- so around 2-3 inches.
I DETEST so-called “recipes” that list ingredients without revealing the proportions. I have cooked many years and have created my own recipes. But, when looking for new ideas, I would like to know how many eggs you used, how much heavy cream you used, etc. I need no videos and very brief instructions. But the proportions are necessary! Without them, this is an idea, not a recipe!
Hi Margo- did you try scrolling down the page to the full recipe card which contains all the details?
Shouldn’t it be 8 or 6 cm? 8” is the size if a victoria sandwich cake!
Apologies- that is correct! Updating it now!
Would 10% cream work?
I’m not sure what that is, I’m afraid- Is it full fat cream? It should be okay, but a little less thick.
Is it possible to make these in a glass pan instead of making separate ramekins? I don’t have any but I would love to make this recipe. Thank you!
of course! Just keep an eye on the baking time, it will likely be longer.
I made this the other day. It was delicious. I plan on making it again soon.
Thanks for the feedback, Rachel!
Easy and delicious!
Great to hear that, Suzanne!
Is there a way to make this butterscotch flavored? My husband is very fond of butterscotch pie.
You could try adding butterscotch extract.
I made this the other day and it was so easy and tasty! 😋 I’m going to try making a coconut version next. Thank you!
Looks fab but when I enter ingredients in MFP my cream is doubling your kcal amount – what cream do you use please?
Double cream, Wolco brand.
Love this recipe! Make it often in a large glass bowl. Could I make it chocolate?
Sure, try and add cocoa powder and see
Can I make this dairy free? Would it be same proportion of coconut cream?
Where does the fiber come from? None of the ingredients have fiber in them…
As wonderful and easy as this is, I just plugged the recipe into my Carb Manager App to add to my daily log later, and it gives me 26g of CARBS per serving (I devised this recipe into 5 ramekins). So… where are you getting 2 net grams of carbs??? The heavy cream has a ton of carbs! What am I missing here? 😣
Bettina, heavy cream has virtually no carbs.
