Prepare the brownie mix according to the package instructions and spread it evenly in the prepared baking dish.
In a mixing bowl, beat the softened cream cheese, sugar, egg, and vanilla extract until smooth and creamy.
Pour the cream cheese mixture over the brownie batter and spread it evenly.
Using a spoon, drop dollops of cherry pie filling onto the cream cheese layer.
Use a knife to gently swirl the cherry pie filling into the cream cheese layer, creating a marbled effect.
Bake in the preheated oven according to the brownie mix package instructions, or until a toothpick inserted into the center comes out clean.
Allow the brownies to cool completely in the pan before cutting them into squares.
Serve and enjoy your delicious Cherry Cheesecake Brownies!
