This deliciously rich and creamy recipe for a Low Carb Custard From Scratch is so simple to make. Made simply from cream, eggs, vanilla extract and sweetener, once you make this there is no making or buying processed custard ever again.

Tips For a Successful Custard

To make this custard you are going to have to focus on making it for about 15-20 minutes. Don’t leave the pot on the stove alone, or you will be at risk of having your custard separate. A couple of tips that are really important for this recipe are don’t allow the cream to boil at the start. Bring it just to the boil but don’t let it bubble up or it will separate.

The second tip is to make sure you wipe out your sauce pan when you pour the custard back into it after you have mixed the hot cream into the eggs, otherwise you will be at risk of having spots where the egg will cook more. This means you will then be at risk of having your custard separate or be lumpy. The third tip is to keep whisking your custard until it thickens over an extremely low temperature so that your custard doesn’t boil or stick in places in the saucepan.

Don’t let these tips turn you off though, as you can always blitz a separated custard with a stick blender to bring it back together it need be. I have never had a failure with this recipe though so have faith.

  • Brandy Custard- blend in 50-100 ml of brandy once you have made the custard.

Recipe Notes

Do not boil the cream mix to prevent splitting.
Continually whisk your custard to prevent separating and lumps forming. Try to whisk in the corners as this is where the custard will thicken.
Ensure your pan is perfectly clean when you pour the custard mix back into it to prevent sticking and lumps forming.
If you have lumps in your custard you can strain it.
Using too high temperature when whisking your custard in step 5 will result in a separated custard.
Halve the recipe to make a smaller amount.
If you want your custard to thicken to use in trifles and other recipes, allow it to cool in the fridge. It thickens beautifully as it cools.
If your custard separates, simply blitz with a stick blender till smooth.

    I used this to make the trifle recipe. Both recipes are delicious. This custard is so creamy. Mine separated a little but I did what was suggested and blitzed it smooth. Yum!
