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?
The Ingredients
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.
The Instructions
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.
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.

This keto custard is a simple and elegant dessert made with just 4 low carb ingredients! No sugar and no thickeners needed!
Preheat the oven to 180C/350F. Grease four 2 or 3 inch ovenproof ramekins and place them in a large baking dish.
In a large mixing bowl, whisk together all your ingredients, until smooth and combined. Transfer the mixture amongst the four ramekins.
Boil a kettle or bring 2-4 cups of water to the boil. Pour enough boiling water into the baking dish until the ramekins are submerged in an inch of water.
Place the baking dish in the oven and bake the custard for around 30 minutes, until firm on top.
Remove from the oven and either enjoy warm or all to cool completely. Once cooled, you can refrigerate it until chilled.

For 1 cup (240 mL) of custard, use 2 tablespoons (17 g) of flour mixed with 4 tablespoons (59 mL) of cold water. Add the mixture into your custard ingredients as they cook on the stove. Use cornstarch as an alternative to flour. Cornstarch, like flour, requires cold water as a mixing agent.

Adding the xanthan gum is crucial as this is what is needed to thicken the liquids and achieve the desired texture. We have used 1 and a half teaspoons of xanthan gum to the recipe, creating a thick yet pourable custard. You may add more or less as desired to reach your preferred consistency.
Strain into a clean, heavy-bottomed pan and heat over a medium heat (be careful not to have the heat too high), stirring constantly until the mixture begins to steam and thicken. The custard is ready when you can draw a clean line through it on the back of a spoon, using your finger.
You don't want the custard so cold that it sets and breaks up as you spread it. The easiest way to cool the custard is to put it into a large bowl in a sink of cold water. It will take about 15 minutes. If you want it to set, put it in the fridge for an hour.
Thickening Agents: Consider adding a thickening agent like cornstarch or flour to the custard mixture. This can help stabilize the filling and prevent excess moisture.
To thicken your custard, place your store-bought custard in a medium saucepan with the vanilla bean paste. In a separate bowl, combine cornflour with 1tbsp water, and mix until well-combined. Add to the custard, and simmer for a few minutes until thickened.
Yes and no. Xanthan gum does not have to be heated to be consumed, so it's used in a wide variety of products, including cold beverages. Cornstarch does need to be heated, so it cannot be consumed raw like xanthan gum. For baking, you can usually use them interchangeably in small amounts.
The more xanthan gum powder added, the thicker your sauce will be. Just be careful not to add too much. Xanthan gum in large amounts will negatively impact the texture of your good and may cause digestive upset.
There are three main varieties of custard: baked custard, stirred custard, and steamed custard. The first two are both popular in Western cuisine. Baked custard is typically firmer and made with whole eggs, while stirred custards can be much runnier and often only contain the yolks.
Here's how to avoid one of the worst kitchen mishaps: overcooking. Egg-based puddings and custards can curdle if cooked beyond 185 degrees. We take crème anglaise off the heat when the mixture registers 175 to 180, but when making the base for ice cream we push the temperature to 180 to 185 for maximum thickness.
Eggs: Four eggs ensure a creamy, thick, and velvety texture. Sugar: Sweeten things up with ½ cup of white sugar. Cornstarch: Cornstarch thickens the custard.
While most custard and pudding recipes both typically call for eggs, the main difference is that pudding uses a starch for thickening, whereas custard's thickening agent is the egg itself (or egg yolk, in most instances). Custard's texture also tends to be firmer than pudding.
If the custard is undercooked it might never set, while if you add the eggs without tempering them or while the mixture is too hot, you might end up with scrambled eggs. If you find yourself with a runny custard, you do have options. One way to combat a custard that will not set is to reboil it.
There are some cooking purists that say that to make proper custard you shouldn't need any flour or cornflour to aid thickening, you should let the egg yolks do all the work.
Yolks contain an enzyme which digests starch after some time, making the whole custard thinner. If you absolutely have to use a custard with both starch and yolks, either consume it quickly, or boil it well (at least of minute of visible bubbling) to deactivate the yolk enzymes.
