Preheat oven to 350℉ and line a large baking sheet with parchment paper.
In a large mixing bowl, whisk together the sugar cookie mix and pumpkin pie spice.
17.5 oz sugar cookie mix, 2 tsp pumpkin pie spice
Mix in the pumpkin purée until a soft dough forms. It may seem too dry at first but if you keep mixing it will come together.
¾ cup Pure Pumpkin
Scoop out balls of dough using a 1 ½ Tablespoon cookie scoop and place them on the prepared baking sheet.
Bake for 16-20 minutes or until the tops of the cookies start to crack and are completely firm to the touch. You will also notice that they start to turn slightly golden brown on the top.
Once done baking, let cookies cool completely, about 30 minutes to an hour.
When cookies have cooled, use a hand or stand mixer to beat together the cream cheese frosting and heavy cream until light and fluffy.
16 oz Cream Cheese Frosting, 2 tbsp heavy whipping cream
Spread the frosting onto each cookie and then sprinkle with pumpkin pie spice if you choose.
