Cream Cheese Layer
8 ounces cream cheese
1/4 cup granulated sugar
1 egg
1/2 teaspoon vanilla extract

Brownie Layer
1/2 cup butter or margarine, melted
1/2 cup granulated sugar
1/2 cup packed brown sugar
1/2 cup cocoa
2 eggs
1/2 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon vanilla extract
12 cream filled chocolate cookies (Oreos), crushed

Cream Cheese Layer: In a small mixing bowl, beat the cream cheese, sugar, egg and vanilla extract until smooth; set aside.

Brownie Layer: Combine butter, sugars and cocoa in a large mixing bowl; blend well. Add eggs, one at a time, beating well after each addition.

Combine flour and baking powder; stir into the cocoa mixture. Stir in vanilla extract and cookie crumbs. Pour into a greased 11 x 7 x 2-inch brownie pan (with high sides). Spoon cream cheese mixture over brownie layer so covers all; cut through with knife to make swirl. Bake at 350 degrees F for 25 to 30 minutes or until a wooden pick inserted near center comes out with moist crumbs. Cool completely.

Yield 2 dozen.
