Fudge Brownies- using sweet potato puree

I can't remember how I found this recipe for brownies, but I was excited because I had lots of sweet potatoes and didn't know exactly what I was going to do with them. My son loooves brownies more than anything and I thought this would be a good way to make a slightly healthier brownie for my kids to enjoy. I cooked a bunch of sweet potatoes in the oven and then pureed them in my food processor. I made these brownies and the Sweet Potato Hummus on the same day, so at least I made my kids eat veggies and hummus before we moved onto the sweets. :D

I had some leftover peanut butter frosting from this Peanut Butter Cake in the fridge and for some reason, I just can't let a little leftover frosting go to waste. Does anyone else have this problem? The frosting I slathered on top probably killed the whole healthy idea, but sometimes, a brownie just needs a little frosting.

My kids didn't know that these had sweet potato puree in them and thought they were great. I am not a brownie fanatic, so I didn't mind that these brownies taste and texture was a little bit different than a normal one. They were still very good and quite fudgy.
