Preheat oven to 350°F. Lightly spray an 8x8-inch baking pan or line with parchment paper. Set aside.
In a medium bowl, with a hand or stand mixer, beat the cream cheese, pumpkin, egg, sugar, pumpkin spice, cinnamon, and salt. Beat on medium speed until the ingredients are well combined and it is smooth. Set aside.
4 ounces cream cheese, ⅔ cup pumpkin puree, 1 large egg, ¼ cup granulated sugar, 1½ teaspoons pumpkin pie spice, 1 teaspoon ground cinnamon
Prepare the brownie mix as directed on the box. Spread ⅔ of the brownie batter into the pan.
18.3 ounces fudge brownie mix, 2 large eggs, ½ cup vegetable oil, 3 tablespoons water
Drop spoonfuls of the cream cheese mixture over the brownie batter as evenly as possible.
Spoon the remaining ⅓ of the brownie batter over the top of the brownies, trying to cover as much as possible.
Use the spoon or toothpick to drag and combine the two mixtures with a swirl.
Bake for 35-40 minutes, until the center is no longer gooey. Remove the pan from the oven and allow it to cool before cutting and serving.
