Melt the white chocolate in a heatproof bowl then stir in the peppermint extract.
Spread the chocolate into your lined tin then top with the crushed candy canes, M&Ms and cake sprinkles.
Leave it to set at room temperature or pop it in the fridge for a couple of hours until the chocolate is fully set. Then break or cut it into pieces and enjoy!
