PREPARE THE PUMPKIN BATTER:
Preheat oven to 350 degrees F. Line the muffin tin with paper liners and set aside.
In the bowl of a stand mixer fitted with a paddle attachment (or using an electric hand mixer), beat together the butter, oil, brown sugar, white sugar, eggs, and pumpkin puree until smooth.
In another bowl, whisk together the flour, pumpkin pie spice, baking powder, salt, and baking soda. Add the flour mixture to the mixing bowl. Mix on slow speed until well combined. Scrape down sides of the bowl as needed to ensure thorough mixing. Set aside.
PREPARE THE CREAM CHEESE BATTER:
Using an electric hand mixer, beat together the cream cheese and sugar until the mixture is smooth. Add the egg, vanilla and salt. Mix until just combined.
ASSEMBLE THE MUFFINS:
Fill the prepared muffin tins with a little over half full of pumpkin batter. Add three dollops of cream cheese (about 1 teaspoon each). Add three dollops of pumpkin batter (about 1 teaspoon each). Use a chopstick, butter knife, or mini offset spatula to swirl together the batter. At this point, the muffin tin should be 3/4 full.
Bake for 23 to 25 minutes, until a toothpick inserted into the center of a muffin comes out clean. Allow the muffins to cool in the tins for 3 to 5 minutes before unmolding. Transfer to a wire rack to cool to room temperature. These muffins can be enjoyed warm or at room temperature.
Muffins will keep at room temperature in an airtight container for two days. For longer storage, keep in an airtight container in the fridge for two additional days.
To make your own pumpkin spice mix: combine 1/2 teaspoon ground cinnamon, 1/4 teaspoon ground nutmeg, 1/8 teaspoon ground cloves, and 1/8 teaspoon all-spice, and a tiny pinch of ground ginger.
To make make cream cheese swirl throughout the entire muffin: fill muffin tin a little over a quarter full with pumpkin batter. Add three dollops each of cream cheese and pumpkin batter. Swirl. Add another three dollops each of cream cheese and pumpkin batter. Swirl. At this point, muffin tin should be about 3/4 full.
