Place ¼ of the biscuits in their bag, leaving the remaining ¾ aside. Loosely twist the top to close. Use a rolling pin to crush the biscuits, then pour into a large mixing bowl. It’s fine to have some bigger chunks left.
250 g arrowroot biscuits
Repeat in ¼ portions until all biscuits are crushed, then place the mixed nuts in the biscuit bag and crush again before adding to the bowl.
1/2 cup mixed nuts
Add the desiccated coconut and unsweetened cocoa, then give the dry ingredients a good mix.
1/3 cup desiccated coconut, 2 tbsp cocoa powder
Heat butter for 30 seconds in the microwave. Pour in the condensed milk and vanilla essence, giving it a stir until loosely mixed, then microwave for a further 30 seconds.
170 g butter, 1/2 tin condensed milk, 1 tsp vanilla essence
Pour the warm mixture over the dry ingredients and combine using a wooden spoon. Make sure there are no dry areas left.
Line a square baking tin with baking paper and pour in the biscuit mixture. Press out firmly with the back of a spoon until packed down and flat.
Break up the milk chocolate into small squares into a small mixing bowl. Melt in the microwave in 30 second bursts, stirring each time, for around 1-2 minutes or until completely melted.
1 block Cadbury milk chocolate
Pour the melted chocolate over the biscuit base and use a spatula or spoon to smooth out the top.
Place in the fridge to set for 1-2 hours before slicing.
Optional: Once set, sprinkle with icing sugar and decorate with maraschino or glacé cherries.
