Chocolate Espresso Swirl Cheesecake
1-1/2 cups chocolate sandwich cookie crumbs (see note)
1/4 cup unsalted butter, melted
4 pkgs. (8 oz. each) cream cheese, softened
1-1/2 cups sugar
1/2 cup sour cream
1 tablespoon instant coffee powder
1 tablespoon hot water
1 teaspoon vanilla
3 ounces bittersweet chocolate, melted and cooled
Grease the sides of a 9-inch spring form pan, or leave a 9-inch cheesecake pan (a straight-sided pan with a drop-out bottom) ungreased.
Make the crust: In a medium bowl, combine the cookie crumbs and butter. Press into the bottom of the pan and freeze.
Center a rack in the oven, and preheat the oven to 350ºF. In a large mixing bowl, beat cream cheese and sugar with an electric mixer set on medium-high speed for 3 minutes. (Use a paddle attachment, if you have
one.) Add sour cream. Add eggs, one at a time, beating after each addition.
In a small bowl, dissolve the instant coffee in the hot water. While the mixer is running, pour the coffee in a steady stream into the batter. Add vanilla. Stir 1 cup of the batter into the melted chocolate, and set aside.
Pour remaining batter over the frozen crust.
Using a spoon, drop the melted chocolate-batter mixture on top of the plain batter in 6 large puddles. Using spiral motions, drag a small knife through the puddles to create a marbling effect.
Bake for 45 to 55 minutes, or until the top is light brown and center has a slight jiggle to it. Cool on rack for 2 hours. Cover with plastic wrap, and refrigerate for at least 6 hours before decorating or serving.
Note: Place about 15 chocolate sandwich cookies in a food processor and pulse until the mixture is the consistency of wet sand. No need to remove the white filling -- it will pulverize.
