cream cheese brownies

I made these after dinner tonight and they were soooooo tasty!! We ate them right after they came from the oven and it was like a warm chocolatey-cheesecake, very similar to what I used to enjoy at O'Carrs in Birmingham!!!

4 unsweetened chocolate baking squares
4 semisweet chocolate baking squares
1/3 cup butter or margarine
2 (3 oz) packages cream cheese, softened
1/4 cup butter or margarine, softened
2 cups sugar, divided
6 large eggs, divided
1 tsp vanilla extract
2 Tbsp all-purpose flour
1 1/2 cups semisweet chocolate morsels, divided
2 tsp vanilla extract
1 cup all purpose flour
1 tsp baking powder
1 tsp salt

Melt first 3 ingredients in a heat-proof bowl (either in the microwave or on the stove), careful not to scorch! cool and set aside.
Beat cream cheese and 1/4 cup butter at medium speed until creamy; gradually add 1/2 cup sugar; beating well. Add 2 eggs, 1 at a time. Stir in 1 tsp vanilla. Fold in 2 Tbsp flour and 1/2 cup chocolate morsels; set aside.
Beat remaining 4 eggs in a large bowl at medium speed. Gradually add remaining sugar, beating well. Add melted chocolate mixture and 2 tsp vanilla; beat mixture until well blended.
Combine 1 cup flour, baking powder, and salt; fold into chocolate batter until blended, and stir in remaining 1 cup chocolate morsels.
Reserve 3 cups chocolate batter; spread remaining batter evenly in a greased 13 x 9 inch pan. Pour cream cheese mixture over batter. Top with reserved 3 cups chocolate batter; swirl with knife.
Bake at 325 for 40 to 45 minutes. Cool and cut brownies into squares. Yields 1 1/2 dozen.
