Decadent Triple Chocolate Mousse Cake

Preheat your oven to 350°F (175°C).
Prepare the chocolate cookie crust according to package instructions, or mix graham cracker crumbs with melted butter to form a crumbly base. Press the mixture into the bottom of a 9-inch pie dish or springform pan to form the crust.
Bake for about 10 minutes until set. Let it cool completely before proceeding.
Make the Cream Cheese Layer:

In a large mixing bowl, beat the softened cream cheese until smooth.
Gradually add powdered sugar and vanilla extract, stirring until well combined.
Pour the cream cheese mixture over the cooled crust and spread evenly.
Chill the Cake:

Refrigerate the cheesecake for at least 2 hours, until it firms up.
Prepare the Cocoa Whipped Cream:

In a separate mixing bowl, whip the heavy cream with the cocoa powder until stiff peaks form.
Spread the whipped cream evenly over the chilled cheesecake layer.
Garnish:

Top with chocolate shavings and place a chocolate truffle on top for a decadent finish.
Final Chill:

Return the cake to the fridge and chill for at least an hour before serving. This helps the layers set and enhances the flavors.
