Preheat the oven to 350F/180C then line a baking sheet with parchment paper or a silicone mat and set it aside.
In a large bowl, whisk the melted butter, pumpkin puree, brown sugar, granulated sugar, egg, and vanilla until smooth.
Gently fold in the flour, baking powder, pumpkin pie spice, ginger, cinnamon, and salt until the dry mixture disappears.
Using a large cookie scooper, scoop out 12 equally sized cookie dough balls and place them on the prepared baking sheet. Gently spray the back of a spoon, or your hands with non-stick cooking spray and flatten the cookies a little to about 2/3 inch in thickness. Bake in the preheated oven for 15-16 minutes, then let the cookies cool down on the baking sheet before transferring to a cooling rack.
Cream cheese frosting
In a stand mixer, cream the softened cream cheese and butter until smooth. Add in the vanilla and powdered sugar and continue whipping for 4-6 minutes or until the frosting is light and fluffy.
Place the frosting in a piping bag with a round piping tip and pipe the frosting on top of the cooled-down cookies. Decorate each cookie with mini chocolate chips and enjoy!
