Why You Will Love This Recipe
Quick and Easy – This recipe is just as simple to make as a traditional custard.
Keto-Pantry Ingredients – Using just four keto essential ingredients, this recipe gives you a silky and delicious custard.
Easily converted – It is easy to convert to a dairy free custard (and paleo custard) by simply substituting cream with coconut cream.
Versatile – Keto Custard can be enjoyed on its own, or as a topping for another keto dessert, like Paleo Chocolate Cake. It can also be used to make other keto desserts. (See the variations below.)
Thermomix Friendly – making sugar free custard in the Thermomix is super easy. The Thermomix custard method is actually one of my favourite keto Thermomix recipes of all time!
The Ingredients
Keep reading for more details on the ingredients, substitutes and step by step instructions on how to make Easy Keto Custard.
Egg custard with just 4 simple ingredients and none of them is sugar!
Thickened cream – This is also known as heavy cream. Use coconut cream for a dairy-free custard recipe.
Vanilla – You can use either vanilla extract or a scraped vanilla bean.
Sweetener – I use Sukrin Melis but you can use Natvia from your local supermarket as well.
Egg Yolks – Egg yolks are a thickening agent and make the egg custard smooth and rich.
How To Make Keto Egg Custard
You can choose to make keto custard in a saucepan on a stove top, or in a Thermomix, Magimix or similar thermal-cooker.

CHEF’S HOT TIP: There are a couple of important things to note with the conventional method to ensure a perfect keto custard.
- Firstly, temperature is very important. When cooking with the conventional method be careful to keep the temperature low. A custard is mainly eggs and if overheated, you will end up with an eggy custard or worse still, sweetened scrambled eggs!
- Secondly, keep whisking continuously and don’t leave the custard unattended while on the heat. It helps to keep the consistency smooth if you are whisking and taking note of the thickening of the keto custard.
Step 1: Add cream and vanilla to a small saucepan. Whisk mixture over medium heat until it reaches a low simmer and remove from heat.
Step 2: In a separate bowl whisk together sweetener and egg yolks. Stir the yolk mixture through the cream mixture. Return the saucepan to the heat, and whisk continuously until the mixture thickens and coats the back of a spoon. (See Recipe Variations * below to make Pastry Cream).
How to Make Custard In a Thermomix
Step 1: Insert whisk attachment. Add ingredients to mixing bowl. Cook 9 min/90 ̊C/Speed 4. Cool.
Recipe Variations
Pastry Cream
After Step 2, whisk 2 tablespoons of butter and ¼ teaspoon xanthan gum into the custard, after taking the saucepan off the heat. Push through a sieve to remove any lumps. Leave to cool at room temperature then press cling film over surface of pastry cream before transferring to the fridge. Refrigerate 2-3 hours.
Chocolate Keto Custard
Add 2 tablespoons of cacao or zero-carb hot chocolate powder. Our Keto Chocolate Pudding is amazing! Another incredible keto egg recipe that is so simple (and the kids will love).
Dairy-Free
You can easily substitute coconut cream for the thickened cream to make a dairy-free option.
Smoothies
Add to a smoothie with some low carb berries.
Custard Ice Cream
Freeze the egg custard and blend to create a delicious ice cream or soft serve custard.
Custard Tart
This Keto Custard will set slightly firm when refrigerated overnight, so it can be poured into a keto shortcrust pastry shell before refrigerating until set. Or you can make our amazing Keto Custard Tart recipe too!
Keto Créme Brûlée
Set the custard in small ramekins or jars. Sprinkle with powdered erythritol. Using a butane torch caramelise the sweetener until you have a crisp toffee bark.
Other Ways To Use Low Carb Custard
Serve over keto desserts like Faux Apple Crumble, or Chocolate Bavarian Pie. It is also delicious as an accompaniment for a simple jelly or low carb berries.
Yes, you can! I have a recipe for Hot Choc Powder in my The Healthy Family cookbook 🙂
This recipe is suitable to be made in larger batches if preferred. You can double, triple or quadruple the recipe if you have a large family.
The custard can be stored in an airtight container in the fridge for up to 3 days. I don’t recommend freezing it as it can separate when defrosting, and it’s much better freshly made.
When pastry cream cools, it can form a skin on the surface. Pressing cling film over the surface stops this from happening.

Best custard recipe. Even non keto people love it! Can’t go past this one! Get it into ya! Lol -
Made the chocolate dairy free variation of this (used the coconut cream)…also added half a tsp of hazelnut extract and doubled the sweetener. Super easy and very tasty! Only made 2 ramekin portions though, so next time will double the recipe! -
Had 3 egg yolks & knew you would have a yummy custard recipe. Amazing, simple & easy. Hit the spot.
-
I love this custard, it’s amazing! How would I go about making it into ice cream? I have a full quart of heavy cream to use up, and figured if I can make ice cream it will last longer than the 3 days in the fridge 😁.
-
Delicious result & easy instructions! Exactly what I was looking for. Not too sweet and was simple to add just a little extra sweetener after it was made to adjust to taste. This will be a new keto staple for sure! Thank you! -
This is an amazing custard recipe!
I added soaked chia seeds to fake it into a “sago” pudding – that my family loves- and sprinkled cinnamon over! Fantastic! My kids couldn’t get enough! -
Lovely! First time ever making my own fresh custard turned out perfect & ate it straight away, definitely itched that craving! I love custard I will never use the other stuff again it was so quick & simple. Thank you so much! 😍 -
What if the eggs cook in the custard can you still use it ,,I haven’t tried making it yet ,

Hi Anne, if the eggs scrambled just run it through a sieve when the custard has thickened.

I tried this custard today. First time ever making a custard that didn’t come from a packet.
I omitted the vanilla as I didn’t have any, and added some 90% dark chocolate.
Tastes amazing. Will definately be making again.-
So glad you enjoyed it Devena. It is so easy to make it in many flavours. Thanks so much for taking the time to leave us a review 💕

I was so happy to see this recipe as I often have egg yolks left over. But how long do I have to stand over custard as I whip it? It doesn’t want to thicken. Will it thicken as it cools? Your help is much needed & always invaluable.-
Hi Jenny, once it it is thick enough to coat a back of spoon remove from the heat. If you refrigerate over night you will end up with thick custard.

OMGEEEE!
If I could give this 10 stars I would. You are bloody amazing Megan!
This custard is out of this world delicious. Actually, it is
sen-bloody-sational!!!!!-
I love this one too Renee. Try a little Avalanche (or my Hot Choc Powder in The Healthy Family) and some mint extract. Leave it in the fridge overnight and it tastes like the best mousse (yep not custard – cannot explain it). So easy and so good. Thanks for the 10 star rating too. I will see if Google can add it 😂
