Line 2 baking sheets with parchment paper (to prevent sticking).

In another large bowl cream together butter and sugar using a hand mixer, add egg and continue mixing for 20-30 seconds, then add pumpkin and vanilla extract and mix for an additional 20-30 seconds or until thoroughly combined.
Stirring by hand, gradually add dry ingredients to wet and mix until all ingredients are well combined and no streaks of dry flour remain.
