Drain the chickpeas and take the liquid - beat it with a kitchen machine or hand mixer for 5-20 minutes until very fluffy and peaks form

Add in the powdered sugar while beating

Add fluffy mixture to the melted chocolate and fold it in, add the vanilla and orange zest

Decorate into glasses and let cool in the fridge for 2-3 hours
