Preheat oven to 180°C. Line 2 baking trays with baking paper.

In a large bowl beat the butter and sugar using an electric mixer until pale and creamy.

Add the egg and beat until well combined. Add the flour and cocoa powder. Stir until combined. Add Violet Crumble Nuggets and chocolate chips and stir to combine.

Roll tablespoons of mixture into balls and arrange on the lined trays, allowing room for spreading. Bake, swapping trays over halfway through cooking, for 10-15 mins or until golden brown. Set aside on the trays to cool.
