Combine water, cocoa powder, sweetener, and ginger in a small saucepan.
Bring to a simmer over medium heat while stirring regularly. Cocoa will sink to the bottom and may burn on the bottom of the pan if it isn’t stirred often.
When the mixture has come to a simmer and the cocoa and sweetener are completely dissolved, remove from heat and stir in the vanilla extract and heavy cream.
Add the Keto Chow and mix with a whisk or an immersion blender until dissolved and the drink is frothy.
Pour into a large mug and garnish with whipped cream if desired.
Notes
*If you prefer a less ginger-y taste, you can omit this for a softer taste.
