Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a mixing bowl, whisk together the flour, baking soda, baking powder, cinnamon, nutmeg, ginger, and salt. Set aside.
In another large bowl, cream together the softened butter and granulated sugar using an electric mixer until fluffy.
Add the pumpkin puree, vanilla extract, and egg to the butter mixture, and beat until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Scoop tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. If desired, use a cookie cutter after scooping to shape the cookies.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Remove from the oven and let the cookies cool on the baking sheets for about 5 minutes before transferring them to a cooling rack to cool completely.
Optionally, dust cooled cookies with powdered sugar before serving.
