"Very easy to put together but I must admit I was skeptical bythe way to look when I put it in the oven. However, they turned out very tasty! If you like peanut butter with your brownies, you'll like this one."

"These are good brownies and the centers are nice and chewy. I think it would have been helpful to add information on melting the chocolate bits to the recipe."
