One box of yellow cake mix
One 15oz can pumpkin puree
1 tbsp pumpkin pie spice (you can always make your own via google.)
Drop tablespoonfuls on greased cookie sheet and bake at 350 degrees for 8-10 minutes.
Depending on size of cookies, it can make from 36 to 60. I think I ended up with 45-47. I also frosted a few of them with cream cheese/greek yogurt/powdered sugar mixture and it totally tasted like pumpkin roll or a pumpkin cinnamon roll. They were still just as good without.
WARNING- MAKES A LOT AND MAY BE ADDICTIVE.
