Preheat your oven to 350F and line a baking sheet with parchment paper.
In a large mixing bowl, add in your melted butter, brown and white sugar, pumpkin puree, vanilla extract and eggs. Whisk together until well combined.
Next add in your baking soda, flour and pumpkin spice and combine everything together.
Lastly, fold in your chocolate chips, mini marshmallows, and graham crackers but be careful not to overmix!
Scoop out cookie dough into even 2 inch balls, spaced 2 inches apart and place on the cookie tray. The cookie dough balls do not need to be perfect!
Bake for 15-17 minutes or until golden brown then remove from oven and place a couple of mini marshmallows on top.
Place in the oven to bake for another 2 minutes.
Transfer to a cooling tray, cool, serve and enjoy!
