Prepare an 8- or 9-inch baking round pan. Lay two or three sheets of parchment paper inside, ensuring at least 2-3 inches of overhang on all sides of the pan. Press down to smooth out as much as possible inside the pan.
In the mixing bowl of a stand mixer with a paddle attachment, add cream cheese and sifted powdered sugar. Mix on low speed until all ingredients are combined. Scrape the sides of the bowl if needed and mix again.
Add pumpkin spice, salt, and pumpkin puree. Mix for a few seconds, then add eggs, one at a time, while mixing on the low speed. Combine heavy cream and corn starch, and add to the mixture. Continue mixing on the low speed until all ingredients are combined.
Combine heavy cream and corn starch, and add to the mixture. Continue mixing on the low speed until all ingredients are combined. The mixture should be smooth.
Transfer the cheesecake mixture into the prepared baking pan.
Bake at 482°F (250 °C) for 15-20 minutes. The center of the cheesecake should be a little wobbly, and the top golden brown. If your oven does not have a convection bake option, then place the baked cheesecake under a broiler to get a brown top. Broiler should be high. Make sure to keep a close eye on the cheesecake and not burn completely.
Remove cheesecake from the oven and leave it at room temperature for a few hours to cool. After that, place the cheesecake in the refrigerator.
When ready to serve, remove the baking pan and carefully transfer the cheesecake to a cutting board. Cut into slices and enjoy!
