Preheat the oven to 350F. Line a baking sheet with parchment paper. Set aside.
In a stand size mixer fitted with the paddle attachment, cream the butter, brown sugar, and granulated sugar together until light and fluffy. About 3 minutes.
Add in the egg yolk and continued to beat on medium speed for about 30 seconds.
Add the pumpkin and vanilla extract, mix on low just until incorporated
On the lowest speed, add in the flour, salt, baking powder, pumpkin pie spice, and the crushed Oreo’s. Mix just until there are no more flour streaks.
Using a large cookie scooper, scoop out 6 equally sized cookie dough balls. Place them on the prepped baking sheet. I crushed two more oreos and topped them for a garnish, this part is totally optional.
Bake for 14-16 minutes, and let them completely cool until serving.
