Chocolate Cheesecake

It's my birthday today! I wasn't going to post on my birthday because I'm not cooking on my birthday (not even for my crying son who is begging for funnel cakes) but my mom made me this chocolate cheesecake so I couldn't resist posting it! This is the first thing I've ever posted that I didn't make myself (I must admit it feels a little weird to post something I didn't cook)! This chocolate cheesecake was perfect, and so delicious with the fresh berries! Mmmm!
So, guess what I got for my birthday?! I'll give you a clue... the first thing I opened was butter! Then I got a pearl necklace... then two Enameled Cast Iron Pots... and three Julia Child books! My presents were Julia Child themed, how cute is that?! I have such a wonderful family! Ingredients
1 1/2 cups chocolate wafer crumbs
1 cup plus 3 tablespoons sugar
3 tablespoons unsalted butter, melted
2 1/2 (8-ounce) packages cream cheese, softened at room temperature
1 1/2 teaspoons vanilla extract
1 vanilla bean, seeds scraped from inside of pod and reserved
3 tablespoons all-purpose flour
3 eggs
1 cup sour cream
8 ounces melted semisweet chocolate, cooled slightly
Fresh berries, for garnish (and to eat with the cheesecake)
Whipped cream, for garnish
Chocolate shavings, for garnish

Directions
Preheat oven to 350 degrees F (if using a silver springform pan, or 325 degrees F if using a dark nonstick springform pan).

Lightly grease the bottom and sides of a 9-inch spring-form pan. In a mixing bowl, combine the chocolate wafer crumbs, 3 tablespoons of the sugar, and the butter and mix well. Press onto the bottom of springform pan and set aside.

In a large mixing bowl with an electric mixer, combine cream cheese, remaining cup of sugar, vanilla extract and vanilla bean seeds and beat until light and creamy. Add the flour to the cream cheese mixture and beat until smooth. Add the melted chocolate and sour cream and mix well. Add the eggs, 1 at a time, mixing on low speed after each addition until just blended. Pour the batter into prepared pan and bake for 1 hour to 1 hour and 10 minutes, until the center is almost set. Run a sharp knife around the rim of the pan and allow cake to cool on a wire rack before removing rim of pan. Refrigerate at least 4 hours or overnight before serving. Cheesecake may be made up to 2 days in advance before serving and will keep for up to 1 week in the refrigerator.

Top the cheesecake with chocolate shavings and serve garnished with fresh berries and whipped cream.
