After googling and pinteresting, I found very little. I decided to improvise and make something up. I give you...
Boxed brownie mix and ingredients to prepare the mix (We used Betty Crocker Gluten Free and it was fantastic)
8 oz. cream cheese
1/2 cup of powdered sugar
1/2 teaspoon vanilla (I know our generic bottle is a sorry excuse for vanilla...but it's cheap!)
Pour the cream cheese mixture on top of the brownies. You can choose to swirl at this stage or you can leave them layered. I opted to layer this time but will probably swirl next time. Completely personal preference.
These were delicious and no one ever has to know I used a box. Desserts like this are perfect if you need a quick dessert and don't have time to make something from scratch. It didn't take that much longer than a regular box of brownies and was absolutely delicious!
