1. Whisk together the 3 eggs. Add cream, Truvia, canned pumpkin purée, pumpkin pie spice, vanilla extract and whisk it all together. Pour it into the formed pie crust.
2. Bake at 350F for 40-50 minutes. The center will still be a little jiggly. You may need to cover the sides with foil if the sides of the crust start to brown too much.
3. Chill for 6-8 hours and serve with additional whipped cream.
