Preheat oven to 350°F (177°C). Line a 9x13 inch pan with parchment paper for easy removal.
Prepare brownie mix according to package or whisk melted butter, sugar, eggs, flour, cocoa powder, vanilla, and salt until smooth. Reserve ¼ cup batter for swirling.
Spread brownie batter evenly in pan. Do not bake yet.
Beat cream cheese and sugar until smooth (about 3 min). Add eggs one at a time, then vanilla, flour, and salt. Mix until creamy. Fold in sour cream if using.
Pour cheesecake mixture over brownie base. Drop spoonfuls of reserved brownie batter on top. Use a toothpick to swirl gently for a marbled effect.
Bake 35–40 minutes or until edges are set and center slightly jiggles. Do not overbake.
Cool at room temperature for 1 hour, then refrigerate at least 3 hours or overnight before slicing.
Lift bars from pan using parchment, slice with a clean knife between cuts, and serve chilled.
