Preheat the oven to 350 degrees
Place the butter in the bowl of a stand mixer with a paddle attachment (or a hand mixer can be used instead)
Pour in the sugar and brown sugar, and cream together (aka mix together) until light and fluffy, making sure to scrape down the sides of the bowl every so often
Stir in the egg, and vanilla, and mix until well combined
Stir in the pumpkin puree and mix until well combined
In another bowl, combine the flour, baking soda, baking powder, salt, and pumpkin pie spice; use a whisk to mix them together well
Slowly pour the flour into butter/sugar mixture and mix until just combined
Stir in the chocolate until evenly mixed, scraping down the sides of the bowl to make sure everything is mixed in being careful not to over-mix
Use a cookie scoop (or two spoons) to scoop out the dough onto a baking sheet lined with parchment paper; you can make them any size you like, but I do the size of about 2 tablespoons, if making them smaller or larger make sure to adjust the baking time
Evenly space the cookies out onto a baking sheet so they are at least a couple of inches away from each other
Bake for 10-12 minutes depending on their size; until the edges are starting to become golden
Allow to cool
*These are best the day they are made because they will have a slight crunch to them. They are delicious the day after as well but they will be softer due to the moisture in the pumpkin
