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 100% beef 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
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.

This was so delicious and tasted just as good as a normal
Custard tart!It sure is good isn’t it!
I have made this custard tart more than 1/2 dozen times in the last three months because we LOVE eating it so much! If you like traditional custard tarts from the bakery then you will relish eating this for only 2gms of carb per generous slice. I have made it baked and chilled overnight in the fridge and we can’t decide which is better. Don’t leave out the fresh shaved nutmeg.Today I have doubled the pastry for the base and used the standard recipe for the filling. Works well if you’re greedy like us and don’t want a 20cm round one. I have used a fluted 30 x 20cm pan a few times now and its always good and I’ve not had a fail with this easy recipe. Thanks Megan you really are the best recipe creator and we love love love your version of so many old favourites. 10/10. Cheers Tracy Australia
I am so happy you love the recipe Tracy. This is one of my favourite recipes and it is just so easy.
Can I sub lactose free cream ? have a little one who is lactose intolerant.I haven’t tested it Jade but I would guess it would be fine.
I made this custard tart today and am so happy with the finished tart. Looks beautiful and I have enjoyed making this from scratch. I did use my thermomix and it made the custard so easily. I did add another 2 minutes for cooking time and it does look wobbly, will transfer to the fridge in 20 minutes to set. Cannot wait to dig in and try this beauty. Thanks again Megan for another fantastic recipe.You are very welcome Tracy. I am just happy the recipe went well for you and you enjoyed it.
