Preheat the oven to 350 degrees.
Prepare a springform pan or a round cake pan with parchment paper and cooking spray.
In the bowl of an electric mixer, combine the boxed cake mix, 1 stick melted butter, and 1 egg and mix in a bowl.
Pour into a prepared round cake pan or springform pan and press an even layer on the bottom of the pan.
In the bowl of an electric mixer, combine pumpkin puree, super soft cream cheese, 3 eggs, dark brown sugar, 1 stick melted butter, vanilla extract cinnamon, ginger, and nutmeg.
Beat on low until the ingredients are fully mixed. Make sure to scrape the bottom and sides of the bowl.
Pour the pumpkin filling over the cake batter in the pan.
Bake in a 350-degree oven for 40 to 50 minutes until the top of the cake is golden brown. The center should be a little gooey.
Let the cake rest for at least 10 minutes before cutting into it.
