Using an electric mixer, beat remaining cream mixture until firm peaks form. Transfer to a piping bag fitted with a large star nozzle. Working quickly, pipe cream mixture over mixture in muffin holes. Freeze for 6 hours or overnight until frozen.
Just before you’re ready to serve, place dark chocolate and Spreadable in a heatproof bowl over a saucepan of simmering water (make sure the base of the bowl doesn’t touch the water). Stir until chocolate has melted.
Remove ice cream from muffin pans. Drizzle with cooled chocolate sauce and serve scattered with the chopped peppermint crisp.
Tips & Hints:
You could replace the chocolate chips with chopped candy canes for an extra strong mint flavour.
