Crush biscuits on Tubro until they resemble fine crumbs (about 5-10 seconds).
Set biscuit crumbs aside.
Chop licorice all sorts by hand (you can do this in the TM but it looks better if you slice them evenly with a knife).
Weigh the condensed milk, butter and golden syrup into TM bowl and melt on Reverse Speed 2 for 3 minutes or until smooth.
Add the crushed biscuits, chopped licorice allsorts and coconut.
Mix together on Reverse Speed 2 until well combined (about 20-30 seconds).
Press the mixture into the base of the prepared pan and set aside for 30 minutes to set.
To make the chocolate topping, melt chocolate and coconut oil on 50 degrees Speed 2 for 3-5 minutes (stop once melted).
Pour the chocolate over the slice and place into the fridge for an hour before cutting into slices.
