This recipe is for cream cheese marbled brownies made with a boxed brownie mix and a cream cheese filling. The filling is made by mixing cream cheese, butter, sugar, eggs, flour and vanilla. Half the brownie batter is spread in a pan, then the filling is spread over it. The remaining batter is spread on top and swirled with the filling for a marbled effect before baking. The brownies are frosted with chocolate frosting after cooling.
