Keto Custard Pie is one of the best keto desserts to make ahead of time for a Mother's Day or Easter. It features a buttery almond flour crust, egg custard made from egg yolks, melted butter and almond milk, made in a tart pan for a beautiful finish with only 3 g net carbs per serving.

Easy Keto Tart Recipe

A low carb egg custard is very comforting and nutritious being rich in egg yolks and butter – both superfoods!

Typically, homemade custard is tricky, and requires lots of stirring time, making it not much of a summer food.

But m favorite keto custard uses real ingredients, and is made from scratch, but with a super easy technique that makes it just about no-fail!

And because using real ingredients is SO satiating, even a small amount with leave you satisfied.

Keto Pie Crust

Keto custard pie starts with a simple almond flour crust.

I use cold butter, a bit of sea salt, vanilla extract, keto sweetener, and almond flour to form a simple, crust, then bake until the edges brown.

Once that crust is cool, it can be filled with the super simple low carb egg custard filling.

Whole Eggs – pasture raised are best, but use what is available to you. Using a whole egg in the recipe raises the protein content, therefore raising the nutritional value and the satiation.

Egg Yolks – the most nutrient-dense part of the egg, essential for a flavorful egg custard.

Heavy Cream – Whipping Cream. If you have dairy free keto lifestyle, swap this out for almond milk, half coconut milk/coconut cream, or your other favorite keto milk.

Keto Sweetener – I use Allulose or Lakanto Baking Sweetener, since both cook and bake very close to sugar, are reasonably priced, and have very little glycemic effect. My picks for keto sweeteners can be found here.

Vanilla Extract – a good quality, real vanilla extract adds so much flavor.

Sea Salt – did you know that salt actually enhances the sweetness of a dish? A good quality sea salt adds trace minerals essential for the keto diet.

Gelatin – we'll add gelatin to my base custard recipe while in the blender, to make it thick enough for a pie or tart filling. (Or, you can use Xanthan Gum. See recipe card for alternative)

LEMON LOVERS – don't worry, a keto lemon tart is coming! (So don't add lemon juice to this recipe 😉

How To Make Keto Egg Custard

Preheat oven to 350.

Prepare a water 9×9 pan by greasing it.  Then, set it inside of a larger pan, and fill the outside pan with very hot or boiling water until the 9×9 pan has 1″ of water coming up the sides.

In your blender, combine all ingredients until smooth.

Pour into the 9×9 pan, then put the entire water bath setup into the oven.

Bake for 35-45 minutes, until the top has just started to brown, but the custard still has a slight jiggle.

Remove from the oven and let cool.

Once cool, scrape the custard mixture into your blender and blend on low, adding the gelatin until smooth.

Pour into prepared and cooled keto pie crust, and allow 2 hours in the refrigerator to set.

Ingredients for Almond Flour Pie Crust

Scroll to the recipe card at the bottom of the post (or use the Jump To Recipe button) for ingredient amounts and cook times for tart shells.

Almond Flour – or almond meal. Scroll to the recipe card for amounts. My picks for good quality almond flour can be found here. If you are nut free, coconut flour can be subbed in, with changes to the butter. See recipe card for alternatives.

Cold Butter – salted or unsalted doesn't matter, it's delicious both ways. Using cold butter makes the crust pressable into the tart pan. Room temperature butter will cause the crust to be too sticky.

Keto Sweetener – I use Allulose or Lakanto Baking Sweetener, since both cook and bake very close to sugar, are reasonably priced, and have very little glycemic effect. My picks for keto sweeteners can be found here.

Vanilla Extract – a good quality, real vanilla extract adds so much flavor.

Sea Salt – did you know that salt actually enhances the sweetness of a dish? A good quality sea salt with also add essential trace minerals.
