Preheat the oven: Set the oven to 350℉. Line a 9×9-inch baking pan with parchment paper and lightly spray it if needed to prevent sticking.
Make the brownie batter: In a mixing bowl, prepare the brownie mix according to the package instructions. Stir in the white chocolate chips for extra sweetness and set aside.
Mix the pumpkin cheesecake layer: In another bowl, beat the cream cheese with a hand mixer until smooth and creamy. Add pumpkin puree, sugar, pumpkin pie spice, ground ginger powder, and vanilla extract. Mix until fully combined and silky.
Layer the batters: Spread the brownie batter evenly into the prepared pan. Pour the pumpkin cheesecake mixture over the top and smooth it out with a spatula for that signature layered look.
Bake the brownies: Bake for 45–50 minutes, or until a toothpick inserted in the center comes out mostly clean.
Cool and serve: Let the brownies cool completely on a wire rack before cutting into 12 squares. Enjoy your fudgy pumpkin cheesecake brownies!
