These Pumpkin Cream Cheese Swirl Brownies are a fantastic way to celebrate the flavors of fall with minimal effort. Using a boxed Betty Crocker Supreme Chocolate Chunk brownie mix as your base makes preparation quick and straightforward. Adding 1 tablespoon of melted butter, 1 teaspoon vanilla extract, and optional espresso powder to the brownie mix enhances the depth of flavor and richness. The pumpkin cream cheese swirl topping is a delightful twist, blending Libby's 100% pure pumpkin puree with softened Philadelphia cream cheese, brown sugar, vanilla extract, pumpkin pie spice, and an egg yolk to create a creamy, spiced layer. This combination complements the chocolate brownie perfectly, offering a balance of sweet and tangy notes. To achieve the beautiful marble effect, dollop the pumpkin mixture over three-quarters of the brownie batter spread in an 8x8-inch pan lined with parchment paper. Then, add the remaining brownie batter in between the dollops and gently swirl with a knife or skewer, but be careful not to overmix. Bake at 350°F (175°C) for 35-40 minutes until a toothpick inserted in the center comes out with moist crumbs, ensuring a fudgy texture. Cooling completely and refrigerating for at least an hour before slicing helps achieve neat edges and a luscious consistency. For added fall flair, consider drizzling pumpkin caramel sauce on top after baking or sprinkling a little extra pumpkin pie spice. This recipe yields 12 servings and is perfect for easy entertaining, potlucks, or cozy family desserts during autumn. Whether you're a pumpkin enthusiast or new to this seasonal ingredient, these brownies bring together the comforting taste of fall with the indulgence of chocolate. Plus, the recipe's simplicity means you don’t need advanced baking skills to create a beautiful and tasty dessert. Enjoy pairing these brownies with a warm cup of coffee or spiced tea for the perfect fall treat.
