White chocolate flavoured buttercream without dairy.
Melt the white chocolate over low heat and set aside to cool completely.
Place the butter into a large bowl and mix in the icing sugar, a little bit at a time.
Add in the cooled melted chocolate and use an electric whisk or stand mixer to whisk it in until light and fluffy. If it's too thick, add a splash of plant-based milk and if it's too runny, place it in the fridge for 30-60 minutes to help it firm up.
