1 (9 inch) prepared chocolate cookie crumb crust
3/4 cup white sugar
3/4 cup butter, softened
1/2 cup white sugar
1 egg
1 teaspoon vanilla extract
1 (8 ounce) package cream cheese, softened
1/2 cup white sugar
1/2 teaspoon vanilla extract
1 (9 inch) prepared graham cracker crust
Preheat oven to 350 degrees F (175 degrees C).
In a medium bowl, cream together the butter and sugar until smooth. Beat in the egg and vanilla extract until smooth, then stir in the cream cheese. Combine the 1/2 cup of the cream cheese, 1/2 cup of sugar and 1/2 teaspoon of vanilla extract in a medium bowl. Spread evenly into the bottom of a 9x13 inch baking pan.
Bake for 8 to 10 minutes in the preheated oven, until a knife inserted into the cake comes out clean. Cool before serving.
