Combine all ingredients together except for the crunch bars,coconut and half cup of milk into the slow cooker.
Cook on high for 1hr
This is a large recipe and will go thick being it is double, so I added half a cup of milk once majority of the ingredients were melted and combined and really stirred it in.
Line a container with baking paper.
Layer the container with crunch bars and sprinkle coconut.
Then pour over the melted chocolate from the slower cooker.
