1. Cream the butter and sugar together in a large mixing bowl with an electric mixer.
2. Add the eggs one at a time, beating well after each addition.
3. Beat in the vanilla and pumpkin until fully blended.
4. In a smaller mixing bowl, sift the flour, baking powder, salt, and spice together.
5. Add this dry mixture into the large bowl and beat on low speed until there are no more dry pieces left.
6. Cut a large piece of parchment paper onto a cookie sheet and drop globs on dough onto it, about 2 inches apart each.
7. For crispy cookies, bake for 10-12 minutes at 425F then let cool on the sheet for at least 5 minutes before transferring to a wire rack.
8. For softer cookies, bake for 15 minutes at 375F then just let cool on the sheet prior to eating.
