01 -  Preheat the oven to 350°F. Grease and flour a 9x13-inch baking pan. 
 02 -  Whisk together all-purpose flour, granulated sugar, baking powder, baking soda, salt, ground cinnamon, ground ginger, ground nutmeg, and ground cloves in a large bowl. 
 03 -  In a separate bowl, mix together pumpkin purée, vegetable oil, whole milk, and eggs until a smooth consistency is achieved. 
 04 -  Add wet ingredients to dry ingredients and stir until just combined, avoiding overmixing. 
 05 -  Pour the cake batter into the prepared pan and spread it evenly. 
 06 -  Beat softened cream cheese, granulated sugar, egg, and vanilla extract in a medium bowl until completely smooth and creamy. 
 07 -  Drop dollops of the cream cheese mixture onto the cake batter and use a butter knife to gently swirl, creating a marbled pattern. 
 08 -  Bake for 40 to 45 minutes, or until a toothpick inserted in the center emerges mostly clean, with some cream cheese possibly remaining on the tester. 
 09 -  Allow the cake to cool completely in the pan before slicing and serving.
