Preparation

Microwave cream cheese in a medium microwave-safe bowl in 15-second bursts, stirring until smooth but not hot. Whisk in sour cream, flour, sugar, vanilla, and salt until smooth. Set aside.

Preheat oven to 350 degrees F. Butter a 9×13-inch pan and line with parchment, leaving a 2-inch overhang.

In a small bowl, whisk flour, pumpkin spice, and salt until well combined.

In a separate large bowl, whisk together butter and brown sugar until completely smooth and incorporated, then whisk in egg and vanilla.

Scrape the sides and bottom of the bowl with a rubber spatula. Whisk in pumpkin puree and scrape sides of the bowl down again, then fold in flour mixture until no streaks remain.

Reserving about ½ cup of pumpkin batter, spread batter evenly into prepared pan. Spread cream cheese topping over the pumpkin batter, leaving a ½-inch border.

Dollop reserved pumpkin batter on top, then use a butter knife or toothpick to swirl pumpkin batter and cream cheese layers together.

Bake until a toothpick inserted in the center comes out with just a few crumbs for about 45 minutes.

Let cool completely in the pan, then cut into bars and serve.
