This is definitely NOT as good as the original recipe. It's fine for what it is: brownies made from a mix. If you're in a hurry and want to jazz up a box of brownies, then this is the recipe for you. If you truly want the taste of Mississippi Mud Cake...take the extra time to make the real deal. This one does not taste like cake...it tastes like boxed brownies.

Just as good as the regular recipe. Made it in cupcake pans so I could bring it to a team gathering. Take them out about 5 minutes early to put the marshmallows on so they don't get so dry.
