Preheat oven to 350°F.
In a medium bowl, whisk together the graham cracker crumbs, flour, baking soda, and salt.
In separate bowl, mix together the coconut oil and sugars until combined.
Beat in the vanilla and egg until well combined.
Gradually add the flour mixture until just combined.
If the dough is too dry, add up to 1 tablespoon of milk. The dough should be the consistency of peanut butter.
Stir in the chocolate chips.
Using a 1.5 T cookie scoop, drop balls of dough onto a parchment lined baking sheet spaced 2 inches apart.
Bake for 12 minutes or until edges are golden brown.
The center of the cookies may look slightly underdone, but should set up nicely as they cool.
