Sugar Free Custard (Keto) Made Stepwise

Step 1: Prepare the Ingredients
Start by gathering all your ingredients. Measure out the coconut cream, egg yolks, powdered sweetener, and vanilla. This will make the process smoother and quicker.
Step 2: Combine the Coconut Cream and Sweetener
In a mixing bowl, combine the coconut cream and powdered sweetener. Use a whisk to mix them together until the sweetener is fully incorporated.
Step 3: Heat the Mixture
Transfer the coconut cream mixture to a double boiler or a saucepan over low heat. Stir gently and continuously until it is warm but not boiling. This process helps dissolve the sweetener completely.
Step 4: Whisk the Egg Yolks
While the coconut cream is heating, whisk the egg yolks in a separate bowl. This step is crucial for achieving a smooth custard.
Step 5: Temper the Egg Yolks
Once the coconut cream is warm, slowly add a few tablespoons of the warm mixture to the egg yolks while whisking vigorously. This process is known as tempering and prevents the yolks from cooking too quickly.
Step 6: Combine Everything
Now, slowly pour the tempered egg yolk mixture back into the saucepan with the remaining coconut cream, whisking constantly.
Step 7: Cook Until Thickened
Continue to cook the custard over low heat, stirring constantly until it thickens, about 5-10 minutes. You know it’s ready when it coats the back of a spoon.
Step 8: Add Vanilla
Remove the custard from the heat and stir in the vanilla bean seeds or vanilla extract for that wonderful flavor.
Step 9: Strain and Cool
For an ultra-smooth texture, strain the custard through a fine mesh strainer into a clean bowl. Allow it to cool to room temperature before transferring to the refrigerator.
Step 10: Chill and Serve
Refrigerate the custard for at least 2-3 hours until it is set. Serve it chilled, and enjoy this delicious Sugar Free Custard (Keto) on its own or with your favorite toppings!
In-Season Swaps

- Coconut cream – Can be swapped with heavy cream for a different flavor profile.

Ask the Chef
Can I use regular sugar instead of powdered sweetener?
While you can use regular sugar, it will affect the carb count and make this recipe no longer keto-friendly. For a sugar-free option, stick with your favorite low-carb sweetener.
How do I know when the custard is thick enough?
The custard is thick enough when it coats the back of a spoon. You should be able to run your finger through it, and it should hold its shape without immediately running back together.
Can I add flavors other than vanilla?
Absolutely! Feel free to experiment with flavors like almond, hazelnut, or even citrus zest for a refreshing twist.
What can I serve with the custard?
This custard pairs beautifully with fresh berries, whipped cream, or even drizzled over keto desserts like Keto Peanut Butter Granola for added texture and flavor.
