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.)

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 YolksEgg 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.

Scroll down to the recipe card for the full recipe, ingredients, tips, and method to make keto milk.

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).

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.

Low Carb Custard is a simple but delicious dessert, perfect for satisfying the “after-dinner” craving for something sweet.

Hot Tips & FAQs

Can I make my own sugar free chocolate powder?

Yes, you can! I have a recipe for Hot Choc Powder in my The Healthy Family cookbook 🙂

Can I made a larger batch of Easy Keto Custard?

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.

How long can I store the custard?

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.

Why do you press the cling film over the surface of the pastry cream?

When pastry cream cools, it can form a skin on the surface. Pressing cling film over the surface stops this from happening.
