Melt the butter in a saucepan over medium heat. Cook, swirling occasionally, until the butter turns a golden brown and smells nutty. Remove from heat and let cool slightly.
In a large bowl, whisk together the browned butter, brown sugar, and granulated sugar until well combined.
Stir in the pumpkin puree, egg, and vanilla extract until smooth.
In a separate bowl, whisk together the flour, baking soda, salt, cinnamon, nutmeg, and ginger.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Fold in the chocolate chips.
Cover the bowl and chill the dough for at least 30 minutes.
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Scoop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between cookies.
Bake for 10-13 minutes, or until the edges are lightly golden and the centers are still slightly soft.
Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
Notes
For extra fudgy cookies, slightly underbake them. Enjoy warm or at room temperature!
