Mix melted butter, sugar, and cocoa powder together. Add pumpkin puree and egg. Mix thoroughly.
In a separate bowl, combine baking soda, salt, cinnamon, pumpkin pie spice, pudding mix, and flour. Add to wet ingredients and mix.Note: If using a stand mixer, just add the dry ingredients to the wet ingredients one by one. You don't need to use a separate bowl.
Stir in chocolate chips. Chill the dough for 30 minutes.
Use a cookie scoop to drop dough onto a parchment paper-lined baking sheet.
Bake at 350 degrees for 7 minutes. Bang the pan against the counter 3-4 times to slightly flatten cookies. Bake for an additional 6 minutes. Bang the pan against the counter 3 more times.
Let cookies cool for 10 minutes before transferring to a cooling rack.
