I've never had the ones from the CP, but I've made this recipe for Chocolate cheesecake bars.
Chocolate Ceesecake Petit Fours
2 8x8 foil pans oven at 325F
Crust: 1 pkg chocolate wafers
8 Tbsp. butter, cut in 1/2" bits and chilled
1/4 tsp. cinnamon
Filling: 8 oz. semi-sweet chocolate
1-1/2 lbs. cream cheese at room temp.
1 cup sugar
3 eggs
4 tsp. cocoa
1 Tbs. instant espresso disolved in 1 tsp. hot water
2 cups sour cream
For crust: Chop cookies until fine crumbs. Add chilled butter and cinnamon and blend until evenly mixed. Divide evenly among pans and press evenly in bottom. Set aside.
For filling: Melt chocolate and let cool. In bowl, beat softened cream cheese until smooth and fluffy and reduce speed and beat in sugar 2 Tbsp. at a time. Then the eggs one at a time. Beat in cocoa, vanilla, coffee, sour cream and the chocolate, blend well after each addition, scraping down sides of bowl occasionally. Pour mixture into prepared pan.
Bake for 1/2 hour and then turn off heat, leave cakes in oven for 15 minutes. Remove from oven, cool and refrigerate until well chilled. Cut into bars and serve. If you just want small bites, cut in 1" squares and serve in mini cupcake papers.
