Pumpkin pie is a Thanksgiving staple. Our version uses a secret ingredient to make it smooth and sliceable without baking it.
In medium microwave-safe bowl, whisk cream and gelatin until all gelatin looks wet (mixture will be slightly lumpy). Let mixture sit for 5 minutes.
Heat gelatin mixture in microwave for 1 minute. Use oven mitts to remove bowl from microwave and whisk until smooth and syrupy. Set aside.
In large microwave-safe bowl, whisk pumpkin, sugar, maple syrup, salt, cinnamon, nutmeg, and ginger until combined. Heat pumpkin mixture in microwave until steaming, about 2 minutes.
Use oven mitts to remove bowl from microwave. Add gelatin mixture to pumpkin mixture and carefully whisk until well combined (ask an adult for help—bowl will be HOT).
