Cream Cheese Brownies

I am not a huge brownie fan, but I tell you my mother-in-law makes the BEST brownies I have ever had.. cream cheese brownies. I was craving some but unfortunately did not have the recipe so I tried a different one and oh man.. not quite my mother-in-law's, but REALLY close!
Ingredients

• 1 package fudge brownie mix (13-inch x 9-inch pan size)
• 1/2 cup vanilla or white chips

FILLING:
• 1 package (3 ounces) cream cheese, softened
• 2 tablespoons butter, softened
• 1/4 cup sugar
• 1 egg
• 1 tablespoon all-purpose flour
• 1/2 teaspoon orange extract

FROSTING:
• 1 ounce unsweetened chocolate
• 1 ounce semisweet chocolate
• 2 tablespoons butter
• 1 cup confectioners' sugar
• 2 to 3 tablespoons milk

Directions
• Prepare brownies according to package directions for cake-like brownies; fold in vanilla chips. Spread half of the batter in a greased 13-in. x 9-in. baking pan.
• In a small bowl, beat the cream cheese, butter and sugar until smooth. Beat in egg, flour and orange extract.
• Carefully spread cream cheese mixture over batter. Drop remaining brownie batter by tablespoonfuls over cream cheese layer. Cut through batter with a knife to swirl.
• Bake at 350° for 30-35 minutes or until a toothpick inserted near the center comes out almost clean. Cool on a wire rack.
• For frosting, in a microwave-safe bowl, melt chocolate and butter; stir until smooth. Cool slightly; stir in confectioners' sugar and enough milk to achieve spreading consistency. Frost brownies. Yield: 16 brownies.
