In a medium bowl combine flour, oats, cinnamon, baking soda, salt, and allspice. Stir to blend well.
In a large bowl combine the sugar, pumpkin puree, oil, maple syrup, and vanilla, whisk to blend.
Gradually stir the dry ingredients into the pumpkin mixture. Stir in raisins.
On a baking sheet with parchment paper, drop one tablespoon of batter, leaving one inch apart between each cookie. Moisten your fingertips and flatten each cookie into a two-inch diameter round.
Sprinkle each cookie with a bit more raw sugar.
Bake the cookies until brown and a bit firm to the touch, 17 to 20 minutes. Transfer the cookies to a rack and cool completely.
Notes
*If you do not have Allspice ground from the store, you can make your own just by mixing up an equal part of cinnamon, cloves, and nutmeg.
