These were very yummy! I ended up putting the marshmallows on top of the batter and baking at 350 for 35 min. No frosting needed in my opinion.
These are SO easy and SOOOOOOOOOOO good. My family inhaled a whole pan full in less than an hour, so I made a 2nd pan for our youth group. They think I'm the greatest thing since chocolate now! CHILL, you outdid yourself with this one. THANK YOU so much for sharing your GREAT recipe!
