Pre-heat the oven to 180°C
Melt butter in a small microwaveable bowl in the microwave in 15 seconds burts (stir each time you check) until runny and melted
Once melted, pour the butter into the tin/dish – don’t worry that it barely covers the bottom as this is how it should be!
Place the biscuits either into a large resealable bag (or do bit by bit in a smaller bag) or place into a large bowl and smash into crumbs with a rolling pin or the bottom of a glass
Pour evenly over the butter layer
Using a chopping board and a sharp knife carefully cut all the chocolate into chunks and sprinkle over the biscuit layer evenly
Chop walnuts in half and sprinkle over chocolate
Open the sweetened condensed milk can and pour evenly over all the layers
Finally sprinkle coconut over the milk layer
Bake for around 25 – 30 minutes or until the edges turn slightly golden brown
Once baked remove from the oven and set the tin/dish on a cooling rack and allow to cool completely
Cut into squares and try the yummiest bar ever!
