Melt the Vitabite in a heatproof dish over a pan of boiling water.
Place the ProZero into a separate pan over a medium heat and add the melted Vitabite.
Stir to combine.
Bring the mixture to the boil and pour into a glass.
Add the marshmallows and the whipped ‘cream’ on the top.
Add some grated Vitabite to the top for an extra sweet kick!
