PEANUT BUTTER MOUSSE CAKE WITH CHOCOLATE CRUST (REFRIGERATOR)

Steps:

• For the crust: set oven to 325°F.
• In a food processor blend the wafers, sugar and cinnamon to fine crumbs.
• Add in melted butter and blend with on/off turns.
• Press the crumb mixture onto bottom and up sides of a 10-inch springform pan (this can be prepared well in advance).
• Bake for about 15 minutes, or until crust starts to puff up and darkens; cool completely.
• For the filling: using an electric mixer, beat the 2 cups peanut butter and softened cream cheese in a large bowl until well blended.
• Add in powdered sugar, and 1-1/2 tablespoons vanilla; beat well until blended.
• Using clean beaters beat the 2 cups whipping cream in a bowl until stiff peaks form.
• Using a spatula fold into peanut butter mixture in three or four additions.
• Spoon into prepared cooled crust.
• For the topping: combine 1/2 cup whipping cream, 1/4 cup sugar and espresso powder in a heavy medium saucepan; stir over medium heat until the espresso powder dissolves and mixture comes to a simmer; remove from heat.
• Add in the chopped chocolate; whisk until melted and smooth.
• Whisk in 1 teaspoon vanilla; cool for 6 minutes.
• Spread topping evenly over the filling.
• Refrigerate cake until cold (about 5 hours, longer is better!).
• Serve cake chilled and keep refrigerated.
