🔪 How to Make Keto Custard

Add the heavy cream and coconut milk to a saucepan and heat until small bubbles start to form around the edges, but do not boil.

In a mixing bowl, add in the egg yolks, allulose, salt, and vanilla bean paste, then whisk to combine until pale in color (about 2 minutes).

If using vanilla extract, wait to add until the custard has been cooked.

Slowly whisk a ladle full of the hot cream into the egg mixture to temper the eggs.

Slowly pour the tempered egg mixture into the saucepan while whisking. 

Simmer the custard, whisking often, for about 8–10 minutes or until thickened enough to coat the back of a spoon.

Remove from the heat and if you are using vanilla extract, whisk it into the custard.  

Pour the custard through a fine-mesh sieve into a bowl. This is to help ensure a smooth texture without any lumps.

Cover with plastic wrap, making sure it’s touching the top of the custard.  This will help prevent skin from forming.

Chill in the fridge for at least 4 hours or overnight. 

Once it has thickened and set, serve with your choice of toppings.  You can also serve while still warm, pouring it over brownies, cake, pie or some fresh berries.

☑️ Storage Instructions

Leftover custard can be stored in the fridge (covered tightly with plastic wrap) for up to 3–4 days. When ready to serve, you may want to give it a good stir to restore its creamy texture.

🍴 Ways to Serve Custard

• Individual cups or jars: Serve custard in small, elegant cups or glass jars for a personal touch 

• Family-style: Present the custard in a large, decorative serving bowl or a shallow dish. Allow guests to scoop out their own serving.

• Layered in a trifle: Create a trifle by layering the custard with pound cake, ladyfingers, or brownies.

• Custard tart: Pour the custard into a pre-baked pie shell and let it set until firm in the fridge.

• Custard shots: Serve the custard in shot glasses for a fun, bite-sized dessert option. This can be especially great at parties or events when there are other desserts to choose from.

💡 Tips for Making the Best Vanilla Custard

• High-quality ingredients: Since this recipe has few ingredients, using high-quality heavy cream, coconut milk, and vanilla can make a significant difference in the flavor.

• Use gentle heat: When heating the cream and coconut milk, do it slowly over medium heat to avoid scorching.  

• Whisk frequently: When combining the hot cream with the egg mixture, whisk constantly and pour slowly to prevent the eggs from scrambling.

• Check for doneness: To know if the custard is thick enough, run your finger through the custard on the back of a spoon. If it leaves a clear path, it’s done.

• Avoid overcooking: Overcooking can cause the custard to curdle. As soon as it thickens and can coat the back of a spoon, remove it from heat.

• Let it cool: Let the custard cool slightly before covering it with plastic wrap. This helps to avoid condensation, which can make the custard watery.

• Store covered: Make sure the plastic wrap touches the surface of the custard to prevent a skin from forming as it cools.

What is the Difference Between Custard and Pudding?

Though the texture is similar, custard is usually thickened using egg yolks, while pudding uses flour or corn starch to thicken the texture.

Is Vanilla Custard Keto?

Absolutely! This recipe for Keto vanilla custard can be enjoyed by anyone looking for a lower-carb dessert option, regardless of whether they follow a keto diet or not.

Why Did My Custard Curdle?

Curdling can happen if the custard is cooked at too high a temperature or if the egg mixture is not tempered properly. To avoid curdling, heat the cream slowly and temper the eggs by gradually adding the hot cream to the eggs while whisking continuously.

Can I Make Keto Vanilla Custard Ahead of Time?

Yes, you can make keto vanilla custard ahead of time. In fact, it often tastes better after chilling in the refrigerator for a few hours or overnight, allowing the flavors to meld.
