Decadent Chocolate Tart

For the crust:
Preheat oven to 350ºF. Combine chocolate cookie crumbs with melted butter and mix until completely combined. Press crumb mixture into the bottom and up the sides of a 9-inch tart pan. Place tart pan on a half sheet pan and bake for 10 minutes. Remove from oven and set aside while preparing the filling.

For the filling:
Place chopped chocolate in a medium bowl; set aside. In a microwave safe container, heat heavy cream and butter until it just begins to boil. Immediately pour heavy cream mixture over chocolate and walk away for a couple of minutes to let cream melt the chocolate. Add espresso powder and vanilla extract to the cream and chocolate; whisk together gently until fully combined. Pour chocolate mixture into chocolate tart crust. Refrigerate at least 4 hours or overnight.

Note: To cut neat slices, dip a knife in hot water and wipe clean each time you slice.
