Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Cream the softened unsalted butter, brown sugar, and granulated sugar until light, fluffy, and pale.

Add the pumpkin puree, large egg, and vanilla extract, mixing until fully combined.

In a separate bowl, whisk together flour, baking soda, pumpkin pie spice, and salt. Gradually add to the wet ingredients.

Fold in chocolate chips, mini marshmallows, and graham crackers.

Drop mounds of dough onto the prepared baking sheet, spacing them about 2 inches apart. Press extra toppings on top.

Bake for 12-14 minutes, until golden brown on the edges and soft in the center.

Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
