Preheat oven to 350

Make brownie mix according to box and pour into a pan

Put aside some mix to make a marble effect later. I usually put aside about a 1/4 cup but I have a rather small pan

In a bowl mix the cream cheese until smooth

Mix in egg sugar and vanilla until smooth

Pour cream cheese mixture on top of the brownie batter

take the extra brownie batter and place it in dolups over the whole pan, leaving some cream cheese showing inbetween

Cut or swirl through batter several times with a knife or fork for a marbled effect. It can be tricky to get a good marble effect so be careful not to over work it.

Bake for 50 minutes or until the cream cheese at the edges turns golden brown
