Mom’s Famous Marshmallow Brownies

Our mom is known all over town for making these amazing brownies!  They are literally my favorite brownies of all time!



These homemade brownies are perfect for feeding a crowd!  Everyone who tastes these always says, “These are the best brownies EVER!”



That marshmallow layer stays perfectly soft to break up the layers of chocolaty goodness!



 I would definitely recommend making these a few hours before serving to allow the frosting to set up completely.
