Chocolate Cheesecake Squares
Line a 9-inch square baking pan with 2 sheets of parchment paper so cheesecake can easily be lifted out later. In a small bowl, combine the graham crumbs, pecans & butter. Press into prepared pan; set aside. In a large bowl, beat cream cheese, sugar & sour cream until smooth. Add eggs; beat on low speed just until combined. Stir in vanilla. Pour over crust.
Bake at 325 F. for 35-40 minutes or until center is almost set. Cool on a wire rack. Refrigerate until chilled. Freeze overnight.
Melt chocolate & shortening; stir until smooth. Cool slightly. Using parchment paper, lift cheesecake out of pan. Gently peel off paper; cut into 49 squares. Remove a few pieces at a time for dipping; keep remaining squares refrigerated until ready to dip.
Using a toothpick, completely dip squares, one at a time, in melted chocolate; allow excess to drip off. Place on waxed paper-lined baking sheets; spoon about 1 tsp chocolate over each, reheating chocolate if needed to finish dipping. Let stand for 20 minutes or until set. Store in airtight container in the refrigerator or freezer. Yield 49 squares.
