In a mixing bowl, beat cream cheese, egg, sugar and salt until smooth. Stir in chocolate chips; set aside. For batter, combine water, oil, vinegar, and vanilla in another mixing bowl.. Combine remaining ingredients; add to the liquid mixture and beat well (batter will be thin). Spoon about 2 teaspoons of batter into greased or paper-lined miniature muffin cups. Top with about 1 teaspoon filling. Bake at 350 degrees for 18-23 minutes or until a toothpick inserted in chocolate portion comes out clean. Cool for 10 minutes; remove to wire racks to cool completely. Yield: 6 dozen. NOTES : "These freeze very well, notes Bertille Cooper of St. Inigoes, Maryland. I like to keep a batch on hand for drop-in guests or when Im too busy to bake." Recipe by: Taste of Home, August/September, 1997 Posted to MC-Recipe Digest V1 #1020 by NGavlak on Jan 17, 1998
