Preheat the oven to 350℉ and prepare your baking sheet with either a silicone mat or parchment paper.
Either use graham cracker crumbs or throw 18 whole graham crackers into a food processors or smash them in a plastic bag until they are crumb size.
In a mixing bowl, whisk together both sugars, baking soda, and salt to combine.
¼ c Granulated sugar, ¼ c Packed dark brown sugar, ½ tsp Baking soda, ¼ tsp Kosher salt
Now, mix in the melted butter, egg, and vanilla and mix with a spatula. Incorporate in the graham cracker crumbs with a spatula.
8 tbsp Unsalted butter, 1 egg, 1 egg yolk, 1 tsp Vanilla extract, 2¾ c Graham cracker crumbs
If you are going to make the smores graham cracker cookies, now is the time to add in the chocolate chips and marshmallows.
1½ c milk chocolate chips, 1 c mini marshmallows
Roll up about 1 ½ Tablespoons of the mix in your hands to form a ball. The heat from your hands really helps with this dough. Try to keep the marshmallows in the center of the dough ball.
Space the dough balls about 2 inches apart. Bake in the preheated oven for 6-7 minutes. Leave the cookies on the baking sheet to cool for 10 minutes before using a flat spatula to transfer off the cookie sheet.
