These brownies combine rich chocolate flavor with a creamy swirl of cream cheese for a delightful treat.
Melt the chocolate chips and butter in a saucepan over low heat, stirring until smooth.
Use a heavy-bottomed saucepan to prevent the chocolate from burning.
Remove from heat and stir in the eggs until well combined.
Let the chocolate mixture cool slightly before adding the eggs to avoid cooking them.
Add the flour, sugar, baking powder, and vanilla extract to the mixture and stir until smooth.
Sift the dry ingredients before adding for a smoother batter.
Fold in the walnuts and pour the batter into a greased baking pan.
Line the pan with parchment paper for easier removal of brownies.
In a separate bowl, beat the cream cheese, powdered sugar, and egg until smooth.
Ensure the cream cheese is at room temperature for easier mixing.
Drop spoonfuls of the cream cheese mixture over the brownie batter and swirl with a knife.
Swirl gently to create a marbled effect without overmixing.
Bake in a preheated oven at 350°F for 25-30 minutes or until set.
Check doneness by inserting a toothpick; it should come out with a few moist crumbs.
Cool the brownies to room temperature, then chill in the refrigerator before cutting into squares.
Chilling helps the brownies set and makes them easier to cut.
