Cupcake Surprise

1 pkg Devil's Food cake mix

Filling:

1/2 cup sugar
8 oz cream cheese, softened
1 egg
dash salt
1 12-16 oz bag of semi-sweet chocolate chips

Preheat oven to 350F. Line muffin tins with paper liners. Prepare cake batter according to directions on box. For the filling, mix sugar, cream cheese, egg and salt until well blended. Fold in chocolate chips. Fill each cup 1/2-2/3 full, then top with rounded tablespoonful of filling. No need to add more cake batter on the top, it will mostly bake over on it's own (plus, they'll be frosted). Bake for 20-25 minutes. Frost with cream cheese frosting. Makes about 24.
