Crush cookies in food processor.
Add melted butter and sugar and pulse to incorporate.
Press 2 tablespoons of mixture into bottom of each jar or glass (I used 7.4 oz Weck Jars).
Refrigerate at least 30 minutes to firm.
In a large bowl, beat cream cheese, brown sugar and sugar until creamy.
Add in pumpkin, vanilla, and pumpkin spice. Beat until fully blended.
Whip heavy cream until stiff peaks form.
Transfer half of whipped cream to piping bag and refrigerate.
Fold pumpkin mixture into remaining whipped cream.
Transfer mixture into another piping bag.
Pipe pumpkin mixture into each jar and place in freezer for 30 minutes.
Pipe whipped cream on top of each jar and dust with pumpkin spice.
Refrigerate at least 2-3 hours before serving.
Note: If your cheesecake is not firming in the 2-3 hours, you can place the cheesecake in the freezer for an hour or two and it should firm right up. I do this often so that the cheesecake can thaw just before serving.
