Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.
In a large mixing bowl, cream the softened butter and sugar together until light and fluffy.
Add the egg, canned pumpkin, and vanilla extract into the butter mixture, mixing until well combined.
In a separate bowl, whisk flour, baking soda, baking powder, pumpkin pie spice, and salt. Gradually add the dry ingredients to the wet mixture.
Drop spoonfuls of dough onto your prepared baking sheet. Bake for about 10-12 minutes, or until the edges are lightly golden.
