Preheat the oven to 350 degrees Fahrenheit. Line 2 baking sheets with parchment paper.
Now, in a large bowl, let's keep it simple. Just mix the 1 (15-ounce) can pumpkin puree and 1 (15.25-ounce) box spice cake mix until they're fully combined. Then, stir in 1 cup milk chocolate chips. It's that easy!
Use a medium cookie scoop to scoop the dough, about 2 ½ tablespoons per cookie, onto the prepared baking sheets, leaving about 2 inches between them.
Bake for 13-15 minutes, until the edges of the cookies are set and begin to turn golden brown. Remove them from the oven and allow them to cool on the baking sheet for 5 minutes before transferring them to a cooling rack to finish cooling.
Notes
Counter or Fridge: Store in an airtight container, single layer. Keeps 4 days at room temp or up to 8 days in the fridge. Cookies get sticky if stacked.
Freeze: Cool completely, then freeze in layers with parchment between cookies. Thaw at room temperature or in the fridge. Keeps up to 3 months.
