I used a Duncan Hines brownie mix. It was impossible to split the brownie in half (It wasn't high enough to make 2 layers), so I settled with just a single layer. Adding 1/2 cup of sour cream to the brownie mixture made the brownie very dry. The topping was terrible! In my opinion, it calls for WAY too much sour cream. And it only calls for 1 TBSP of powdered sugar. I ended up putting 3 TBSP's of powdered sugar in the topping to try and make it taste better, but it still tasted terrible. We tasted the finished product (which looked pretty with the fruit on top), but basically, the whole thing went straight to the trash. Sorry, but I won't make this again.
