Scroll to the bottom of this post for the amount of each ingredient needed to make my gluten-free custard tart recipe.
- Thickened cream – or heavy cream. For a dairy-free keto custard tart swap the cream for coconut milk, almond milk, hemp mylk or your favourite keto milk.
- Powdered Erythritol – I use Sukrin Melis. For me Sukrin’s sugar free icing mixture has no weird aftertaste. 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!
Step by Step Instructions
STEP 1. Add the cream and vanilla to a small saucepan. Whisk over medium heat until it reaches a low simmer. Remove from the heat.
If making with a Thermomix. Place all the keto custard ingredients into the mixer; mix 7 sec/speed 5. Store in an airtight jar in the fridge for up to 1 week.
STEP 2. In a separate bowl whisk together sweetener, gelatin and egg yolks.
STEP 3. Pour half of the warmed cream into the eggs and whisk to combine then pour back into the remaining cream in the saucepan.
Cook whisking over the heat until the custard thickens and coats the back of a spoon. Remove from heat and allow to cool for 10 minutes.
STEP 4. Preheat the oven to 160°C. Pour the cooled custard into the prebaked almond flour pie crust. Transfer to the oven and bake for 10-12 minutes or custard is beginning to set. *SEE NOTES
Sprinkle the custard tart with finely grated nutmeg. Leave to cool at room temperature for 20 minutes then loosely cover with clingfilm and refrigerate for 3 hours or until set.
Hot Tips and FAQs
You can use whole eggs if preferred. Using egg yolks creates a creamier 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.
Store in the fridge for up to 5 days in an airtight container. Do not freeze as the custard can split.
I add the gelatin as I like the extra stability it adds to the custard tart. You can leave it out if you prefer.

Keto Custard Tart
Add the cream and vanilla to a small saucepan. Whisk over medium heat until it reaches a low simmer. Remove from the heat.
In a separate bowl whisk together sweetener, gelatin and egg yolks. Pour half of the warmed cream into the eggs and whisk to combine then pour back into the remaining cream in the saucepan. Cook whisking over the heat until the custard thickens and coats the back of a spoon. Remove from heat and allow to cool for 10 minutes.
Preheat the oven to 160°C.
Pour the cooled custard into the prebaked almond flour pie crust. Transfer to the oven and bake for 10-12 minutes or custard is beginning to set. *SEE NOTES
Sprinkle with finely grated nutmeg. Leave to cool at room temperature for 20 minutes then loosely cover with clingfilm and refrigerate for 3 hours or until set.
Insert the whisk attachment. Add the cream, vanilla, sweetener, gelatin, and egg yolks to the mixer; cook 9 min/90°C/speed 3. Leave to cool for 10 minutes. Follow from step 3 above.
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 flavour but the sheer scent of it takes the whole experience up a notch or two.
