Drain the chickpeas from its water and you will get the Aquafaba.

With an electric mixer beat the Aquafaba water until whipped and stiff peaks form.

This should take around 7-10 minutes. Make sure you really beat it that long, otherwise the the mousse will not last long.

Add the sweetener of your choice (Xylit or Erythrit).

Melt the chocolate in the microwave and whisk with a small spoon until all the chunks have fully dissolved. Add the cinnamon. Mix the chocolate into the mousse and fill into small glasses. Allow the mousse to set for 3 hours in the fridge.

Decorate with chocolate sprinkles and enjoy!
