Step 1

In a large saucepan over medium heat, whisk together water, sweetener, cocoa powder, and salt. Continue to whisk until well combined.

Step 2

Bring to a boil and let cook, not stirring, for 4 to 5 minutes, until it's thickened. Watch it carefully so it doesn't boil over. It will bubble very thickly when it's ready.

Step 3

Remove from heat and add vanilla. Whisk to combine. Let cool half an hour before transferring to a jar or bottle.

Step 4

Pour over ice cream or stir into your favorite low carb milk. If adding to milk, you may need to add a bit more sweetener to taste.
