This chocolate-espresso cheesecake is easy, delicious and fun to make. With a divine, crisp Oreo cookie crust, its flavor is deep and rich, and the texture is creamy and smooth.
Use a food processor fitted with the blade attachment to grind the Oreos into a fine crumb.
Pour the ground Oreos into a large mixing bowl and mix in the espresso powder and melted butter.
Add this mixture to the bottom of a 9 X 3-inch springform pan, and use your hands to gently press it down firmly.
Add the finely chopped chocolate to a small mixing bowl. In a small saucepan, scald the cream. Tiny bubbles will appear on the edges and it should be very hot, but not boiling. Pour the cream over the chocolate. Do not stir it yet – wait about 4 minutes and then, use a wooden spoon and stir to combine. It will take a few minutes of mixing before you see it come together. (This is Ganache.)
Let it cool slightly and then pour it directly on the prepared crust. Place the springform pan on a baking sheet in the refrigerator until this layer solidifies, at least 1 hour. (You want it totally firm.)
Melt 1 cup of chocolate and mix in the espresso powder. Set aside to cool.
Add the cream cheese to a food processor fitted with the blade attachment, or a bowl with an electric mixer. Blend for about 30 seconds. Then add the vanilla and powdered sugar, and blend until it's velvety smooth. Use a rubber spatula to scrape in all of the chocolate-espresso mixture. Mix to blend.
Fold the whipped cream into the cream cheese mixture just until it’s combined.
Once it's been an hour, remove crust from the refrigerator and pour in the filling. Smooth the top and cover with plastic wrap. Refrigerate overnight (at least 12 hours.)
Use a knife to loosen the chilled cheesecake from the rim of the springform pan, then remove the rim. Sprinkle the top with the remaining 1/2 cup of chocolate. Slice and serve.
