Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.

In a medium saucepan, melt the unsalted butter. Remove from heat and stir in the granulated sugar and brown sugar until combined. Beat in the eggs, one at a time, and add in the vanilla extract.

In a separate bowl, whisk together the all-purpose flour, cocoa powder, and salt. Gradually stir this dry mixture into the wet mixture until just combined.

Pour half of the brownie batter into the greased pan and spread it evenly.

In another bowl, combine the softened cream cheese and powdered sugar using a hand mixer until smooth. Gently spoon this cheesecake layer over the brownie batter.

Pour the remaining brownie batter over the cream cheese layer and use a knife to swirl it slightly for a marbled effect.

Spoon the cherry pie filling over the top of the batter, distributing it evenly.

Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted comes out mostly clean.

Once done, remove from the oven and allow to cool before cutting into squares.
