Description: This makes a big 13x9 pan of brownies, using a brownie box mix. Super easy and looks gourmet when you are done! (Important!!! Be sure to buy the box mix that says that it makes a 13x9 recipe or you'll have problems.) The mix I use is by Betty Crocker. Also, cooking in a glass pan may take a few minutes longer than a metal so check the doneness with a toothpick in the middle.
Prepare the brownie mix according to package directions (water, oil, eggs).
Pour into a greased 13x9-inch baking pan.
Beat cream cheese with electric mixer on medium speed until smooth.
Add sugar and mix. Add vanilla and egg; mix until well-blended.
Place cheese mixture in dolups over the whole pan, leaving some brownie showing in-between.
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 35 to 40 minutes. Cool; cut into squares. (These will also freeze well).
