Preheat the oven to 180°C and line a 12 hole cupcake tin with cases.
In a large bowl add the dairy free butter and caster sugar, beat until light and fluffy. Add the eggs one at a time and continue to beat until combined.
Add the peppermint and vanilla extract and beat again. Stir in the self raising flour and cocoa powder until combined.
Fold through the chocolate chips and then divide the mixture between the 12 cupcake cases. Bake for 25 minutes or until a skewer comes out clean. Leave to cool before making the buttercream.
