Creating this incredible Pumpkin Gooey Butter Cake is easy when you follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish or pan.

2. Prepare Cake Base: In a large mixing bowl, combine the yellow cake mix, melted butter, and 1 egg. Mix until well blended and the mixture appears crumbly. Press this mixture evenly into the bottom of the prepared baking dish.

3. Mix Cream Cheese Layer: In another bowl, beat the softened cream cheese until smooth. Gradually add in the powdered sugar, mixing well. Then, add the pumpkin puree, 2 eggs, and vanilla extract. Finally, incorporate the ground cinnamon, nutmeg, and ginger.

4. Blend Until Smooth: Continue mixing until all ingredients are well combined and the mixture is smooth.

5. Spread Over Base: Pour the pumpkin mixture over the cake base in the baking dish, spreading it evenly.

6. Add Pudding Mix: In a separate bowl, whisk together the butterscotch pudding mix and a cup of milk (or follow the instructions on the packaging). Pour this mixture over the pumpkin layer, but do not stir; it will create a delightful gooey topping as it bakes.

7. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the edges are golden brown and the center is set.

8. Cool: Remove the cake from the oven and let it cool in the pan for about 15-20 minutes before slicing.

9. Dust with Powdered Sugar: Dust the top of the cake with powdered sugar for added sweetness and presentation.
