Preheat the oven to 350°F and prep a 12-hole cupcake pan with cupcake liners.
Add the flour, baking powder, baking soda, salt, and pumpkin pie spice to a mixing bowl and whisk to combine.
In a separate bowl, whisk together the pumpkin puree, oil, eggs, sugar, and vanilla extract.
Add the dry ingredients to the bowl with the wet ingredients and whisk together until just combined.
Distribute the mixture evenly between your 12 cupcake liners.
Bake for 20 minutes or until a skewer poked into the center of a cupcake comes out clean.
Leave the cupcakes in the pan for about 15 minutes before transferring to a wire rack to cool completely.
