This no-bake chocolate raspberry truffle cake is perfect for those who don't want to turn on the oven. The cake is made with a chocolate cookie crust, a creamy chocolate filling, and a raspberry sauce. To make the crust, simply crush chocolate cookies and mix them with melted butter. Press the mixture into a springform pan and refrigerate. For the filling, melt chocolate and mix it with cream cheese and whipped cream. Pour the mixture over the crust and refrigerate until set. For the raspberry sauce, blend fresh raspberries with sugar and strain the mixture. Drizzle the sauce over the cake and garnish with fresh raspberries.
