How to make
Crumble the biscuits finely. To them add the cocoa, powdered sugar and butter, which needs to be melted ahead of time (in the microwave is best).
Stir everything until it becomes a dough and form rock confectioneries. Leave in a cold area for 20 min.
Melt the milk chocolate in a water bath, pour it over the tops of the rock confectioneries, sprinkle coconut flakes. Serve cooled.
Bon appetit!
