Grease a 23cm bundt tin with butter (make sure to grease it really well so that the rocky road wreath comes out!).
Crush ¼ cup of Clinkers in the Thermomix bowl by pressing Turbo 5-10 times.
In a large bowl, place the peanut M&Ms, the halved Clinkers, mini marshmallows, coconut and crushed peanuts. Mix until well combined.
Meanwhile, grate the chocolate on Speed 8 for 15 seconds and then melt for 5 minutes, 50 degrees, Speed 3 (scraping down the sides occasionally). Pour the melted chocolate over the other ingredients and stir quickly.
Spoon the rocky road mixture into the prepared bundt tin and press down firmly (with the palm of your hand or the back of a spoon).
Place the wreath into the fridge to set for 2-3 hours.
Take the rocky road wreath out of the fridge and allow to come to room temperature.
Place a chopping board over the top of the bundt tin and turn over. Place the board down firmly and the rocky road wreath will come out. If it’s a little stuck, rub your warm hands over the outside of the tin to loosen it from the edges. You can also gently use a knife to loosen it.
Leave the rocky road wreath on the chopping board.
Melt the white chocolate in the Thermomix bowl for 3 minutes, 50 degrees, Speed 3 (or until melted). Drizzle the white chocolate over the top of the wreath in a zig zag pattern.
Sprinkle over the crushed Clinkers.
Place a small blob of melted white chocolate into the top of the wreath and place a Jaffa and two spearmint leaves on (as pictured). Hold in place until they have set firm. Repeat with the remaining Jaffas and spearmint leaves.
Store in an airtight container in the fridge for up to a week.
