The Ingredients
Scroll to the bottom of this post for the amount of each ingredient needed to make my healthy custard tart recipe.
- 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!
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 fan/180°C static/350°F. 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 egg 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. The
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.

I grew up loving a great custard tart and was so excited to bake this recipe. It is every bit as good as I remember a shop bought one to be. This is a KETO custard tart with only 1g of net carbs in each slice so that is a huge win for me. I will be making this on a regular basis and I love the suggestions for other flavours. This is such an easy, delicious custard tart recipe. I think everyone should make this and if you are a custard tart fan you won’t be disappointed.-
Thanks for testing it out Lynda and taking the time to come back and leave a review. I am so happy you enjoyed it.

This is absolutely the BEST custard tart that you will ever taste! No-one would ever know that it is Keto. You make it with easy to source ingredients and the pie crust only uses a few.. so simple to make. Next time I am going to fold some sugar free lemon curd through it. Delish!-
Haha! So glad you enjoyed it and thanks for testing it out so soon Helen.
