Soft, chewy pumpkin snickerdoodles wrapped around a creamy cheesecake center and rolled in fragrant cinnamon pumpkin spice sugar. Melted butter and blotted pumpkin keep them thick and tender rather than cakey, while cream of tartar gives them their classic snickerdoodle tang.
Use block-style full-fat cream cheese rather than the spreadable tub kind, which contains too much water and will leak during baking.
If the dough feels too soft to handle after chilling, return it to the fridge for another 20 minutes. Warm kitchens can slow it down.
If any filling leaks out, the seal had a small gap or the filling was not frozen firmly enough. Freeze the portions a little longer next time and check each ball carefully before coating.
If your cookies bake up puffy and cakey, the pumpkin likely needed more blotting. Weighing it after blotting is more reliable than measuring by eye.
Store cooled cookies in an airtight container in the refrigerator for up to 4 days. Let them sit at room temperature for 15 to 20 minutes before serving, or warm one in the microwave for 5 to 8 seconds.
The filling portions can be frozen on their own for up to 1 month. Assembled, coated dough balls freeze for up to 2 months and bake straight from frozen at 350°F, adding 2 to 4 minutes to the baking time.
