Gently combine the melted chocolate mixture with the creamy egg mixture. Then sift in the dry ingredients — the flour, cocoa, and salt — and fold everything until it's just mixed. Don't stir more than you need to!

Pour half the brownie mix into your pan. Scoop dollops of the cheesecake filling and pistachio spread randomly on top. Carefully spread the rest of the brownie batter over the layer.

Scatter chocolate chunks over the top. Bake at 340°F for roughly 27 minutes for gooey brownies, or closer to 30-35 minutes if you want them firmer. The center should still wiggle slightly when done.
