Preheat the oven to 375.
Crust:
1 1/4 cup crushed graham cracker crumbs
3 tablespoons butter
3 tablespoons sugar
Mix the graham cracker crumbs, butter, and sugar in a small bowl. Press firmly onto the bottom of a springform pan.
Filling:
1 8 oz package low-fat cream cheese
1 8 oz package regular cream cheese
3/4 cup sugar
1/3 cup cocoa powder (I use Hershey's)
1 teaspoon Penzey's Mexican vanilla
2 eggs
In a large bowl, blend all ingredients well with electric mixer. Pour into crust.
Bake for 30 minutes and remove from oven.
Topping:
1 cup low-fat sour cream
2 tablespoons sugar
1 teaspoon Penzey's Mexican vanilla
Increase the oven temp to 425. Stir together the sour cream, sugar, and vanilla in a small bowl. Carefully spread the sour cream mixture evenly over the top of the cheesecake. Bake for 10 more minutes and remove from oven. Let cool for 20 minutes and remove the rim from cheesecake, and slide the cheesecake off of the baking pan onto a plate, and chill. Cut and serve. Sprinkle with cocoa powder.
