Place the chocolate into a heatproof bowl and melt over bain-marie.
In a small saucepan add cream and milk and bring to a simmer.
Gradually incorporate into melted chocolate.
Add butter and stir until melted.
Take the cake out of the refrigerator, remove the ring and acetate sheet and place the cake over a rack or simply on a bowl or pan that is placed on a plastic wrap or parchment paper lined baking sheet to collect the excess.
Pour the glaze on top and edges of the cake. Use an offset spatula to remove the drips.
Transfer the cake to a serving platter and refrigerate for 30 minutes to set the glaze.
Decorate the bottom of the cake with mini chocolate rocks.
Top with fresh raspberries and chocolate decorations. Dust with powdered sugar.
Enjoy!
