Spray a non stick brownie pan liberally with non stick cooking spray. Set aside.
To a large mixing bowl add the cookie mix, 1/2 cup of the chocolate chips, flour, and spice to a large mixing bowl. Stir to evenly combine the ingredients.
1 17.5 oz pkg chocolate chip cookie mix, 3/4 cup semi sweet chocolate chips, 1/4 cup flour, 1 tsp pumpkin pie spice
Add the puree to the mixing bowl, and stir again until the dough comes together and is evenly combined. It will be thick, but smooth.
3/4 cup pumpkin puree
Transfer the dough to the prepared pan and press it out in an even layer. Sprinkle the remaining chocolate chips evenly out overtop of the dough.
Bake at 350° for 25-27 minutes, or until a toothpick inserted comes out clean.
Carefully remove the hot pan from the oven and let it rest and cool for 15 minutes.
Cut into squares, serve, and enjoy!
