In a large mixing bowl, combine all-purpose flour, brown sugar, and melted butter. Mix until the texture resembles coarse crumbs. Set aside some for topping.

Preheat your oven to 350°F (175°C). Line a square baking dish with parchment paper. Press the crumb mixture into the bottom and bake for 15-20 minutes until lightly golden.

Blend cream cheese, granulated sugar, egg, and vanilla extract until smooth and creamy in a separate bowl.

In a saucepan over medium heat, combine cranberries, sugar, and orange zest. Cook for about 10 minutes until cranberries burst and mixture thickens.

Spread the cream cheese mixture over the cooled crust, then spoon the cranberry sauce on top and swirl together.

Sprinkle the reserved crumb mixture over the cranberry layer for topping.

Bake at 350°F (175°C) for 30 minutes until edges are golden and filling is set.

Let the bars cool on a wire rack for 30 minutes, then refrigerate for at least 2 hours before slicing.
