Preheat oven to 350.
Cream butter until light and fluffy, about a minute.
Next, add in sugars and cream until combined.
Add in the pumpkin puree, vanilla extract, and salt. Mix.
In a small bowl, mix flour, baking soda, cinnamon, nutmeg, all spice, and cloves.
Mix with wet ingredients.
Once combined, add in chips. Stir.
Allow the dough to chill for at least 30 minutes in the fridge (or freeze cookie sheet of made dough balls for 5 minutes before baking).
Take about 2 Tbsp of dough and flatten it slightly in your hand. Stick a half marshmallow in the center, and fold the cookie dough around the marshmallows, forming it into a ball (watch video below for more info). Make sure the marshmallow is completely covered by the dough.
Place evenly on a cookie sheet, and bake for 13-15 minutes, or until golden brown.
Enjoy!
