Large Batch of Brownies

I turned my back for two minutes to get something and look what my lovely daughters did to the brownies! I was taking them to an activity and I was pretty frustrated when I returned to find these little wholes punched through- the little stinkers! I guess they liked them though.

I'm just really loving brownies right now! I got this recipe almost 5 years ago attached to one of those awesome metal baking sheets for our wedding from good old Julie Ferguson. I had never tried the recipe and then I came across it yesterday. It was pretty good for a really big batch. (I have to admit that Jenster's Brownies still have it for me, but these were good.) Are there bad brownies?
