巧克力芝士蛋糕

                
                
我很喜欢芝士蛋糕，十有九次，在众多口味中我会点巧克力口味。朋友送了我一些非常高品质的无糖纯黑巧克力，正好可以用来做这个蛋糕。店力买的通常都太甜，不适合亚洲人的口味，所以自己做又有乐趣又好吃^^

Chocolate Cheesecake Crust:
1 1/2 cups (150 grams) chocolate wafer crumbs
1/3 cup (75 grams) unsalted butter, melted
Filling:
12 ounces (340 grams) semi-sweet or bittersweet chocolate, chopped
24 ounces (680 grams) (3 - 8 ounces packages) full fat cream cheese, room temperature
1 cup (200 grams) granulated white sugar
3 large eggs, room temperature
1 1/2 teaspoons pure vanilla extract
1 cup (240 ml) full fat or light sour cream, room temperature
Ganache:
4 ounces (115 grams) semi-sweet or bittersweet chocolate, chopped
1/3 cup (80 ml) heavy whipping cream
1 teaspoon unsalted butter, room temperature
Chocolate Cheesecake: Butter or spray with a non stick vegetable spray, a 10 inch (25 cm) spring form pan. Preheat oven to 350 degrees F (180 degrees C) with rack in center of oven.
Crust: In a medium sized bowl combine the chocolate wafer crumbs and melted butter. Press the crumbs evenly over the bottom of the spring form pan. Cover and refrigerate while you make the filling.
For Filling: Melt the chopped chocolate in a stainless steel bowl placed over a saucepan of simmering water, stirring until smooth. Remove from heat and set aside to cool.
Meanwhile, in the bowl of your electric mixer (or with a hand mixer) beat the cream cheese, on medium low speed, until smooth. Gradually beat in the sugar. Add the melted chocolate and beat until fully incorporated. Add the eggs, one at a time, beating well (about 30 seconds) after each addition. Scrape down the sides of the bowl as needed. Add the vanilla extract and sour cream and beat until thoroughly incorporated. Remove the crust from the refrigerator and pour in the filling. Place the cheesecake pan on a larger baking pan and place in the oven.
Bake for about 50 - 55 minutes or until firm yet the center of the cheesecake will still look a little wet and wobbly. Remove from oven and carefully run a knife or spatula around the inside edge of pan to loosen the cheesecake (helps prevent the surface from cracking as it cools). Let cool and then cover with plastic wrap and refrigerate for a few hours before covering with the ganache.
Ganache: Place the chopped chocolate in a stainless steel bowl. Heat the cream and butter in a small saucepan over medium heat. Bring just to a boil. Immediately pour the boiling cream over the chocolate and allow to stand for a few minutes. Stir until smooth. Cool slightly and then pour over cheesecake. With an offset spatula or back of a spoon, evenly spread the ganache over the top of the cheesecake. Cover and return to the refrigerator for several hours or overnight. This cheesecake tastes best after being refrigerated for at least a day. Serve in small slices.
Serves at 12 - 16 people.
