Preheat the oven to 350°F (if using a glass pie plate, reduce to 325°F). Line a sheet pan with parchment paper. Generously coat a 9-inch pie plate with nonstick spray, then place it on the baking sheet.
In a large bowl, whisk together the eggs, egg yolk, and pumpkin.
Whisk in the cornstarch, then once it’s smoothly combined, whisk in the maple syrup.
Whisk in the granulated sugar, then the cinnamon, ginger, nutmeg, cloves, and salt.
Gently pour in the evaporated milk, then whisk to combine.
Pour the mixture into the prepared dish, filling it, no more than 3/4 of the way (if you’re using a regular pie dish, you will have some extra. You can bake it in well-greased muffin tins as mini pies at 350 degrees for 15 to 25 minutes, depending upon the size of your muffin tin). Before baking, tap the dish on the counter gently several times to remove any air bubbles. Place on a parchment lined baking sheet to catch any drips and bake for 50 to 60 minutes, or until the edges are set and the center of the pie is just slightly wobbly (similar to a pudding). Cool completely on a wire rack for at least 3 hours. Serve at room temperature or chilled, with lots of whipped cream.
