1 family size brownie mix
1 lg. pkg. cream cheese
5 tbsp. butter
5 eggs
2 tbsp. flour
3/4 tsp. vanilla
1/3 c. sugar
1 c. sour cream

CREAM CHEESE MIXTURE: Cream cheese and butter together. Add sugar, 2 eggs, flour and vanilla. Beat until smooth. Set aside.

BROWNIE BATTER: Using an electric mixer, combine brownie mix, 3 eggs, 1 cup sour cream and vanilla.

Pour half of the brownie batter into a greased 9x13 inch pan. Pour all of the cream cheese mixture over the batter; then add the other half of the brownie mix. Pull a knife through the batter in wide curves to create a swirled appearance. Bake at 350 degrees for 35 to 40 minutes.
