In a large bowl using a stand or hand mixer, whisk your heavy cream until stiff peaks form. Place your bowl in your fridge.
In another bowl (still using an electric mixer), whisk together your cream cheese, pumpkin puree, powdered monk fruit, vanilla extract, and pumpkin spice. Whisk for about 2 minutes on medium-high.
Gently fold half of your pumpkin puree mix into your whipped cream until combined. Add in the rest of your pumpkin puree mix and mix until incorporated and you have a mousse texture.
Cover your bowl and refrigerate for 4 hours, up to overnight and enjoy!
