In case you wish to eat an entire box of cereal in one sitting, first melt butter and gingerbread flavored marshmallows (or plain marshmallows if you ate the gingerbread ones in December like a normal person) into the creamy consistency they were born to be. *Melted marshmallows is the reason why God created Food Scientists.
Stir in cereal. Press into pan.
Eat one sticky, crunchy, bite after the other until all you have left to show for your efforts is the hardest to clean bowl ever.
