Preheat the oven to 350 degrees Fahrenheit and line a 9x9 inch baking pan with parchment paper or spray generously with cooking spray.
Whisk together the chocolate chip cookie mix, ½ cup of chocolate chips, all-purpose flour, and pumpkin pie spice in a large mixing bowl until combined.
17.5 ounce bag of chocolate chip cookie mix, ¾ cup semi-sweet chocolate chips, ¼ cup all-purpose flour, 3 teaspoons pumpkin pie spice
Mix in the pumpkin puree until a smooth, thick dough forms. It will look like it will be too dry, but if you mix it well, it will come together as a sticky dough. If needed, use clean hands to knead it together.
¾ cup pumpkin puree
Press the dough into the prepared baking pan, and spread it into an even layer with a spatula or spreading knife.
Sprinkle the remaining ¼ cup chocolate chips on top.
Bake for 23-28 minutes or until a toothpick comes out clean and the top bounces back when gently tapped.
Allow to cool for at least 15 minutes before cutting into squares and serving.
Notes
Storage:
To Store: You can store the Pumpkin Chocolate Chip Bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week.
To Freeze: Individually wrap the bars in plastic and place them in a freezer-safe container or bag in the freezer for up to 3 months. Thaw at room temperature or in the refrigerator before serving.
Tips:
Make sure to use pumpkin puree, NOT pumpkin pie filling (which has already been sweetened and spiced).
I like to line my baking dish with parchment paper before pressing the dough in the pan. I usually leave enough parchment hanging over the edges of the pan so that I can easily lift the bars out once baked. It makes both removal and clean up a lot easier.
If you prefer a sweeter taste, add 1/4 to 1/2 cup of granulated or brown sugar to the dough.
For a healthier version, you can use whole wheat flour instead of all-purpose flour and reduce the amount of chocolate chips added.
Feel free to add cinnamon or vanilla extract to the dough for extra flavor.
