Preheat oven to 350ºF.
Cream together the butter and the sugars until well mixed.
Beat in the pumpkin, eggs and vanilla. It's okay if the batter looks a little curdled.
In a separate bowl whisk together the flour, salt, baking powder, baking soda and spices.
With the mixer at low speed, stir the flour mixture into the pumpkin mixture.
Stir in any of the optional additions you might be using.
Drop by Tablespoons onto parchment lined cookie sheets, at least 2 inches apart. Don't press them down, leave them round on the cookie sheet.
Bake for 11-13 minutes or until light golden brown.
Cool cookies on racks.
When completely cooled put the cookie racks on top of waxed paper, then drizzle the Maple Glaze on top of each cookie.
Let glaze dry and serve!
