40g cocoa power, 80ml strong coffee cooled, 350g icing sugar, 70g butter, 1tsp vanilla extract
- Mix together the cocoa powder and coffee until combined and set aside. Whisk the butter until light and fluffy then add the icing sugar and vanilla extract.
- Stir through the mocha mixture until fully combined. For a thicker mixture allow to set in the fridge before using and for a thinner mixture add a splash of milk or water until you reach the right consistency.
