Preheat the oven to 350 degrees Fahrenheit. Line a cookie sheet with parchment paper, and set it aside.
Cream the butter, brown sugar, and granulated sugar in a large mixing bowl until combined, and light and fluffy, about 2 to 3 minutes. 1/2 cup Unsalted Butter, 3/4 cup Brown Sugar, 1/4 cup Granulated Sugar
Add in the egg, and vanilla extract and mix until combined. 1 Large Egg. 1 tsp Vanilla Extract
Add in the dry ingredients; flour, 1 cup of the graham cracker crumbs, baking soda, baking powder, and salt and mix until you have a thick cookie dough. 1 1/4 cup All Purpose Flour, 1 1/2 cup Graham Cracker Cookie Crumbs, 3/4 tsp Baking Soda, 1/2 tsp Baking Powder, 1/2 tsp Salt
Portion the dough into 1/4 cup portions, and roll them into round balls.
Roll the balls of cookie dough into the remaining 1/2 cup of the graham cracker crumbs, and place them on the prepared cookie sheet, at least 3 to 4 inches apart. (Only 6 cookies per sheet).
Gently flatten the cookie dough balls slightly to make them into a thick disk.
Bake the cookies for 10 to 13 minutes, or until the edges are set and the cookies start to crinkle on top.
Remove the cookies from the oven and let them cool on the cookie sheet for 10 minutes, then transfer them to a wire rack to cool completely.
