Creating Fluffy Whipped Pumpkin Mousse is simple and enjoyable. Follow these steps to make your delicious dessert:

1. Prepare the Gelatin (if using): In a small bowl, sprinkle the gelatin over cold water. Let it sit for about 5 minutes to bloom.
2. Heat the Gelatin: Once bloomed, gently heat the gelatin mixture in the microwave for about 10 seconds until fully dissolved. Allow it to cool slightly before using.
3. Mix Pumpkin Base: In a large bowl, combine the pumpkin puree, powdered sugar, vanilla extract, pumpkin pie spice, ground cinnamon, and salt. Stir until smooth and well combined.
4. Incorporate Gelatin: If using gelatin, slowly mix it into the pumpkin mixture, ensuring it is evenly distributed.
5. Whip the Cream: In a separate bowl, whip the heavy cream until stiff peaks form. Be careful not to over-whip.
6. Fold the Cream: Gently fold the whipped cream into the pumpkin mixture, being careful to maintain the light and airy texture.
7. Chill the Mousse: Transfer the mousse into individual serving cups or a large bowl. Cover with plastic wrap and refrigerate for at least 1 hour to allow it to set.
8. Prepare to Serve: Once chilled, you can garnish with additional whipped cream, a sprinkle of cinnamon, or even some crushed graham crackers for added texture.
