Grab your cream cheese and beat it until it's nice and smooth. Mix in the sugar, egg, vanilla, and flour just until everything's combined - don't overdo it. Pop it in the fridge while you work on the brownies.

Line an 8x8 inch baking pan with parchment paper. In a heatproof bowl, melt the butter and dark chocolate together (either microwave in short bursts or over simmering water). In a separate bowl, mix the eggs, both sugars, and vanilla for about 3 minutes until you get a creamy, slightly fluffy mixture.

Pour that melted chocolate mixture into your egg mixture and fold it in gently. Sift in the flour, cocoa powder, and salt, then fold everything together until just combined. Don't overmix!

Spread about half the brownie batter into your prepared pan. Drop spoonfuls of the cheesecake mixture and pistachio spread randomly across the surface. Then cover everything with the remaining brownie batter, spreading it out gently.

Sprinkle those chunks of dark chocolate across the top. Slide the pan into a 340°F oven and bake for about 27 minutes if you want them fudgy, or 30-35 minutes if you prefer them more set. The middle should still have a slight wobble when done.
