My family loves when I bake brownies and can't ever seem to wait for them to cool down before hacking into the pan! This usually leads to uneven pieces, lots of crumbs and a big mess. For many years I have baked my brownies (both homemade and from a box mix) in muffin pans. I just spray the pans lightly with non-stick spray and bake them for about 10 minutes less than I would in a traditional pan. The pop out of the pan easily and you have those perfect chewy edges all the way around!
I like to make these to stash in lunchboxes and they are great for taking to banquets, potluck gatherings or bakes sales. I have even topped them with a mini swirl of homemade cream cheese frosting and stuck a few M&M's in my daughter's school colors right in the center. They are always a big hit!
