Before anything else, preheat your oven to 375°F (190°C).
In a large mixing bowl, beat the softened butter just a bit to loosen it up. Then, add the brown sugar, granulated sugar, egg, vanilla extract, and pumpkin puree. Mix everything together until it’s well combined and smooth.
In a separate medium bowl, whisk together the flour, salt, baking soda, cinnamon, and pumpkin pie spice.
Now, slowly add the dry ingredients to the wet ingredients, mixing as you go. Make sure you don’t overmix—just stir until everything is combined.
Fold in those sweet, creamy white chocolate chips.
Pop the cookie dough in the refrigerator to chill for about 30 minutes.
Once your dough is chilled, use a 1 1/2-inch cookie scoop to scoop the dough onto a prepared baking sheet. Make sure to leave a bit of space between each scoop for the cookies to spread. Bake for 12-14 minutes until the edges are set and slightly golden.
After baking, let the cookies cool for 1-2 minutes on the baking sheet before transferring them to a wire rack to cool completely.
