Place 10 Oreos (as original recipe is written // adjust if altering batch size) on a baking sheet and top with a marshmallow (or several minis).
*I didn't coin the term S'moreo! Not sure who did, but they're smart. I first saw it on Top with Cinnamon
*Vegan marshmallow brands I'm currently aware of: Dandies
*Nutrition information is a rough estimate.
