  • Coarse graham cracker crumbs are best: Although you can crush your graham cracker to whatever consistency you like, I found leaving large chunks to create the most authentic tasting/feeling s’more cookies.
  • Use a 60% cacao or higher chocolate for a rich, chocolaty flavor
  • The importance of leaving cookies on the baking sheet: The goal of taking the cookies out when they’re no longer shiny is to keep them from becoming too browned or drying out. At this point, they’ll be slightly under-cooked, and leaving them on the hot baking sheet allows them to finish cooking through without browning further.
  • Toasting marshmallows: If you like a really toasty marshmallow, you can further toast them using a culinary torch.
  • Storage: These cookies can be kept in an air tight container at room temperature for up to a week or frozen (I like to individually wrap mine in plastic wrap) for up to 6 months.
