Irish Cream Chocolate Cheesecake

Ingredients:

1 1/2 cups chocolate cookie crumbs (I used keebler fudge stripes)
1/3 cups confectioners sugar
1/3 unsweetened cocoa powder
1/4 cup butter
3 (8oz) packages cream cheese, softened
1 1/4 cups white sugar
1/4 cup unsweetened cocoa powder
3 tablespoons all-purpose flour
3 eggs
1/2 cup sour cream
1/4 cup irish cream liqueur

Directions:

1. 1) Preheat oven to 350 degrees F (175 degrees C). In a large bowl, mix together the cookie crumbs, confectioners' sugar and 1/3 cup cocoa. Add melted butter and stir until well mixed. Pat into the bottom of a 9 inch springform pan. Bake in preheated oven for 10 minutes; set aside. Increase oven temperature to 450 degrees F (230 degrees C).
2. 2) In a large bowl, combine cream cheese, white sugar, 1/4 cup cocoa and flour. Beat at medium speed until well blended and smooth. Add eggs one at a time, mixing well after each addition. Blend in the sour cream and Irish cream liqueur; mixing on low speed. Pour filling over baked crust.
3. 3) Bake at 450 degrees F (230 degrees C) for 10 minutes. Reduce oven temperature to 250 degrees F (120 degrees C), and continue baking for 60 minutes.
4. 4) With a knife, loosen cake from rim of pan. Let cool, then remove the rim of pan. Chill before serving. If your cake cracks, a helpful tip is to dampen a spatula and smooth the top, then sprinkle with some chocolate wafer crumbs.
