Brownies
1 cup butter, softened to room temperature
4 ounces unsweetened chocolate, coarsely chopped
2 cups granulated sugar
2 tsp vanilla extract
1 cup flour
Filling
1 (8-ounce) package cream cheese, softened
1/4 cup granulated sugar
1 egg
1 tsp mint extract
4 drops of green food coloring
Frosting
2 tbsp butter
2 tbsp corn syrup
2 tbsp water
2 ounces unsweetened chocolate
1 tsp vanilla
1 cup powdered sugar
Heat oven to 350 degrees. Grease and flour a 9 x 13" pan and set aside.
To Prepare the Filling: In a small bowl, combine the cream cheese and 1/4 cup sugar; beat until smooth. Add 1 egg, the mint extract and food coloring. Mix well and set aside.
To Prepare the Brownies: In a large saucepan, melt 1 cup butter and 4 ounces unsweetened chocolate over very low heat, stirring constantly until the butter and chocolate have melted. Remove from heat and cool for 15 minutes, or until slightly cooled. Stir in the 2 cups sugar and 2 tsp vanilla. Add the 4 eggs, one egg at a time, beating well after each addition. Stir in the flour, and mix well.
Spread in the prepared pan and carefully spoon the Filling over the brownie mixture. Lightly swirl the filling into the brownie mixture. Bake 350 degrees for 45-50 minutes, or until set. Let cool completely before frosting.
To Prepare the Frosting: In a medium saucepan, combine the 2 tbsp butter, corn syrup, and water; bring to a boil. Remove from heat and add the 2 ounces of chocolate, stirring until melted. Stir in the 1 tsp vanilla and powdered sugar; and beat until smooth. Frost the cooled brownies and once the frosting has set, cut into bars.
NOTE: Because of the cream cheese mixture, these brownies should be stored in the refrigerator.
