Preheat your oven to 350°F (175°C). Line an 8×8 inch baking dish with parchment paper for easy removal later.

In a medium bowl, beat together the softened cream cheese and sugar until smooth. Add the eggs one at a time, then mix in the vanilla extract. Set this mixture aside.

In another large bowl, mix together the melted butter and cocoa powder, ensuring there are no lumps. Gradually add the flour and salt, stirring until the mixture is well combined.

Take half of the brownie batter and spread it evenly in the prepared baking dish. Pour the cream cheese mixture over the brownie layer, smoothing it out with a spatula.

Dollop the remaining brownie batter over the cream cheese layer. Use a knife to create a gentle swirl pattern to visually combine the layers.

Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Allow the brownies to cool completely before slicing into squares.
