Preheat the oven to 350 degrees F and spray the cake pan of your choice -- 9x13, Bundt, cupcakes, 2-8 or 9-inch round, etc.
In a large bowl, mix all the cake ingredients until well combined. About 2 minutes on medium-high.
Pour the batter into the pan of your choice.
Make the filling by creaming together softened cream cheese and sugar. Then add in the oil and egg. Mix until smooth.
Fold in the white chocolate chips.
Drop the cream cheese filling into the cake batter by the spoonful. Allow the filling to sink into the batter.
Swirl a knife through the filling a bit to make sure the filling is covered by the batter.
Bake until a toothpick inserted into the center of the cake comes out clean.
Cool 10 minutes in the pan if you are inverting to a plate for serving. If you baked in a 9x13 pan, no need to invert.
Allow to cool completely. Cover with foil or plastic wrap. Even better when served the next day.
Notes
Hint: Starting with softened cream cheese is essential for a smooth cheesecake filling. See the FAQ section for tips on softening the cream cheese.Be sure most of the filling has sunk into the cake mix before baking. If the filling stays at the top, it can overcook. Ensure you use plain canned pumpkin -- NOT pumpkin pie mix.
