Step 1

Preheat the oven to 350ºF. Set four 4-ounce ramekins inside a larger baking dish.

Step 2

Add the whipping cream, eggs, egg yolk, sweetener, vanilla extract, and salt to a blender. Pulse a few times until well combined.

Step 3

Divide the custard mixture between the ramekins and sprinkle the tops nutmeg or cinnamon.

Step 4

Fill the baking dish with enough hot water to reach halfway up the sides of the ramekins. Do not get any water inside the ramekins.

Step 5

Place the baking dish in the preheated oven and bake 35 to 45 minutes, or until a knife inserted in the center comes out clean but the custard still jiggles slightly when shaken.

Step 6

Remove the baking dish from the oven and carefully remove the custards from the baking dish. Let cool completely.
