The Ingredients

Scroll to the bottom of this post for the amount of each ingredient needed to make my healthy custard tart recipe.

Keto Custard Tart Ingredients in small bowls.
  • Thickened cream – or heavy cream. For a dairy free keto custard tart swap the cream for peanut milk, coconut cream, almond milk, hemp mylk or your favourite keto milk.
  • Powdered Erythritol – I use Lakanto Powdered Sweetener. It is zero calorie and zero carb.
  • Gelatin – I use Locako pasture-fed gelatin but it is completely up to you what you use. The gelatin can also be omitted if preferred it does help with setting the custard.
  • Vanilla – add vanilla extract or any of your favourite extracts. I also love citrus or coffee extract in the pie crust as well.
  • Nutmeg – I always freshly grate the nutmeg as it is crazy-good!

Hot Tips and FAQs

Can I make whole egg custard?

You can use whole eggs if preferred. Using egg yolks creates a creamier custard.

Do I need to bake the custard? I hate baked custard.

After making the custard leave it to rest at room temperature for 1 hour. Pour into the prebaked keto pie crust and refrigerate overnight. The custard will set without baking.

How do I store custard tarts? Can I freeze custard?

Store in the fridge for up to 5 days in an airtight container. Do not freeze as the custard can split.

Why do you add gelatin when you are baking the custard tart?

I add the gelatin as I like the extra stability it adds to the custard tart. You can leave it out if you prefer.

Notes

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! 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. When custard cools, it can form a skin on the surface. Pressing cling film over the surface stops this from happening.
To Bake or Not to Bake – The custard can be set without baking in the pie shell. Simply pour the cooled custard in and set it overnight in the fridge.
Storing and Freezing – the custard can be stored in an airtight container in the fridge for up to 3 days.
To brulee, the top sprinkle with powdered or granulated sweetener and use a butane torch to caramelise it. Freshly grate the nutmeg over the custard tart. I find it not only adds amazing flavor, but the sheer scent of it takes the whole experience up a notch or two.
