This keto custard recipe is a creamy and satisfying dessert that’s low in carbs and high in flavor. Whether you’re following a keto diet or just looking for a delicious sugar-free dessert, this custard is sure to satisfy your sweet tooth.


  • 2 cups heavy cream
  • 4 large eggs
  • 1/3 cup granulated erythritol (or other keto-friendly sweetener of choice)
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • Ground nutmeg (for garnish, optional)


  1. Preheat the Oven: Preheat your oven to 325°F (160°C). Place four ramekins or custard cups in a baking dish large enough to hold them comfortably.
  2. Heat the Cream: In a saucepan over medium heat, warm the heavy cream until it begins to steam. Do not boil. Remove from the heat and leave to partially cool.
  3. Beat the Eggs: In a mixing bowl, whisk the eggs until well beaten.
  4. Add Sweetener and Flavor: Gradually add the erythritol, vanilla extract, and salt to the beaten eggs. While stirring, the sweetener must be well dissolved.
  5. Combine with Cream: Slowly pour the warm cream into the egg mixture, stirring continuously to prevent curdling. This creates the custard base.
  6. Strain the Mixture: Pour the custard mixture through a fine-mesh strainer into a large measuring cup or bowl. This step helps ensure a silky-smooth custard.
  7. Fill the Ramekins: Divide the custard mixture evenly among the ramekins.
  8. Create a Water Bath: Place the baking dish with the ramekins in the preheated oven. Carefully pour hot water into the baking dish to create a water bath, filling it about halfway up the sides of the ramekins. This gentle, even heating prevents the custard from curdling or cracking.
  9. Bake: Bake for approximately 30-35 minutes, or until the custard is set around the edges but slightly jiggly in the center. Your oven will determine the exact timing.
  10. Chill: Remove the ramekins from the water bath and let them cool to room temperature. Then, cover and refrigerate for at least 2 hours or until completely chilled.
  11. Serve: When ready to serve, sprinkle a pinch of ground nutmeg on top of each custard, if desired.
  12. Enjoy: Dive your spoon into the creamy keto custard and savor the delightful flavors without the guilt of excessive carbs.
