1 pkg. Betty Crocker super moist German chocolate cake mix
1 (8 oz.) pkg. cream cheese, softened
1 egg
1/2 c. sugar
1/2 c. milk chocolate chips

Heat oven to 350 degrees. Grease and flour jelly roll pan. Prepare cake mix as directed on package. Pour batter into pan. Mix remaining ingredients. Drop by tablespoonfuls onto batter. Cut through batter with knife or metal spatula several times for marble effect. Sprinkle with additional chocolate chips and chopped nuts if desired. Bake until cake springs back when touched lightly, 25 to 30 minutes.
