In a medium bowl pour in melted butter and sugar and whisk together.
Measure out the pumpkin puree and then dump it onto a paper towel. Blot the top of the pumpkin with another paper towel then whisk it into the butter and sugar.
Whisk in spices, salt, and baking soda. Make sure baking soda is whisked in very well and there are no chunks.
Measure in the flour and stir in with a wooden spoon.
Cover the dough and allow it to rest in the fridge for at least an hour or longer.
When you are ready to bake. Preheat the oven to 350.
Scoop out about a heaping tablespoon of dough and roll it into a ball and press it down gently with your fingers.
Continue to do this until you have used all the dough. You can sprinkle a little granulated sugar on the top of each cookie (this is optional).
Bake at 350 for about 10-12 minutes or until the edges are brown and the center is a little soft.
