2/3 cup miniature semisweet chocolate chips, divided
1 package (8 ounces) cream cheese, softened
2/3 cup sweetened condensed milk
1 egg, lightly beaten
3/4 teaspoon vanilla extract
In a small bowl, combine the cracker crumbs, sugar and cocoa; stir in butter. Press onto the bottom of a greased 8-in. square baking dish. Bake at 325° for 10-12 minutes or until golden brown. Cool on a wire rack.
In a microwave, melt 1/3 cup chocolate chips; stir until smooth. Set aside. In a small bowl, beat cream cheese until fluffy; gradually beat in milk and melted chips. Add egg and vanilla; beat on low speed just until combined. Pour over crust; sprinkle with remaining chips.
Bake at 325° for 15-20 minutes or until set. Cool on a wire rack for 1 hour. Cover and refrigerate for 2 hours or until chilled. Cut into squares. Refrigerate leftovers.
