In a small bowl, combine 1st layer crust ingredients and mix until crumbs form. Spread into an 8 by 8 parchment lined baking dish. Set aside.
If you prefer to bake the crust, bake in a preheated oven at 350 degrees F for 8-10 minutes and cool completely.
Add the cream cheese and pumpkin puree to a stand mixer or use a mixing bowl and hand mixer to whip until smooth. Add remaining ingredients and allow the mixer to go a few minutes to whip the cream. Alternately, you could whip the heavy cream in a separate bowl and fold into the pumpkin cream cheese mixture.
Taste and adjust to determine sweetness level.
Spread over the cooled crust.
Make the topping by adding the ingredients to a stand mixer or large bowl and whip until stiff peaks then spread over the pumpkin cheesecake layer.
Cover with plastic wrap and refrigerate until ready to serve.
Store in the fridge in an airtight container for up to 5 days.
