Preheat your oven to 425°F (220°C). Place an oven rack in the lower-middle position to help the bottom crust bake properly. Prepare a 9-inch pie dish with your unbaked pie crust, pressing it gently into the dish and crimping the edges as desired.
In a large mixing bowl, combine the granulated sugar, brown sugar, cinnamon, ginger, nutmeg, cloves, and salt. Stir thoroughly to distribute the spices evenly. This helps prevent concentrated pockets of spice in the finished filling.
Add the pumpkin puree and eggs to the bowl. Whisk until the mixture becomes smooth and evenly combined. Avoid incorporating excessive air, as too many air bubbles can affect the appearance of the finished custard.
Gradually whisk in the evaporated milk and vanilla extract, if using. Continue mixing until the filling is silky and uniform. Make sure you use plain pumpkin puree rather than sweetened pumpkin pie filling, which already contains sugar and spices.
Pour the pumpkin mixture into the prepared pie crust. Gently tap the dish on the counter to release large air bubbles. If necessary, smooth the surface with a spatula and carefully transfer the pie to the oven.
Bake at 425°F (220°C) for 15 minutes. Without removing the pie for too long, reduce the oven temperature to 350°F (175°C) and continue baking for approximately 35–45 minutes.The filling should be mostly set, with the center still slightly wobbly when the pie is gently moved. If the crust edges begin to brown too quickly, cover them with a pie shield or strips of aluminum foil. Remove the pie from the oven and place it on a wire rack. Allow it to cool for at least 2–3 hours so the custard can finish setting. Avoid cutting it while it is hot, because the filling may still be too soft to hold its shape.For the cleanest slices and best make-ahead results, refrigerate the cooled pie before serving. If desired, beat the heavy whipping cream with powdered sugar and vanilla until soft or medium peaks form. Serve a generous spoonful alongside each slice of pumpkin pie. Finish with a light sprinkle of cinnamon for an attractive presentation.
