Instructions

1 Preheat oven to 350 degrees F (175 degrees C). In a medium bowl, combine cookie crumbs, almonds, 1/4 cup sugar and melted butter. Mix well. Press into the bottom and halfway up the sides of a 10 inch springform pan.

2 In the top of a double boiler, heat chocolate, stirring occasionally, until chocolate is melted and smooth. Remove from heat and allow to cool to lukewarm.

3 In a large bowl, beat the cream cheese and 1 cup sugar until smooth. Beat in the eggs one at a time. Fold in the almond extract and sour cream. Pour 1 1/2 cups of the filling into a smaller bowl. Stir the melted chocolate into the smaller bowl, then fold loosely back into plain filling. Pour into crust. With the tip of a knife, swirl the filling to create a marbled effect.

4 Bake in the preheated oven for 40 minutes. Turn off oven and let cake cool in oven for 1 hour, with the door closed. Cool at room temperature, then refrigerate overnight.
