Directions

1. In a small saucepan, combine the water, butter and chocolate. Cook and stir over low heat until melted; stir until smooth. Cool.
2. In a large bowl, combine the flour, brown sugar, baking soda and salt. Beat in the egg, egg white and sour cream on low speed just until combined. Beat in chocolate mixture until smooth. In another bowl, beat the cream cheese, sugar, egg white and vanilla until smooth; set aside.
3. Spread chocolate batter into a 15x10x1-in. baking pan coated with cooking spray. Drop the cream cheese mixture by tablespoonfuls over batter; cut through batter with a knife to swirl. Sprinkle with chocolate chips.
4. Bake at 375° for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack.
