This dark chocolate raspberry mousse cake is a chocolate lover's dream. With a food processor, blend chocolate cookies, sugar, and melted butter to make the crust. For the mousse, blend fresh raspberries, sugar, and cream cheese until smooth. Melt dark chocolate and fold it into the mousse mixture. Pour the mixture over the crust and chill the cake for a few hours before serving. The result is a rich and decadent cake with a perfect balance of dark chocolate and tangy raspberries.
