"Create a one-bowl dessert called You’re Not Sorry Midnight Salted Dark Chocolate Skillet Brownies, inspired by Taylor Swift’s ‘You’re Not Sorry.’ Vibe: decisive, moody, grown-up sweetness with a bitter edge.Core: unsalted butter (or neutral oil), granulated sugar, brown sugar, eggs, vanilla, unsweetened cocoa powder, all-purpose flour, baking powder, fine salt, optional espresso powder, dark chocolate chips/chunks; optional chopped walnuts.Method: melt butter; whisk in sugars → eggs (one at a time) → vanilla; sift in cocoa, flour, baking powder, salt (and espresso powder); fold in chocolate chips (and nuts if using); spread into a greased 9-inch cast-iron skillet (or 8×8 pan); bake until set at edges and fudgy in center.Serve: warm slices with a light sprinkle of flaky salt; vanilla ice cream optional.Include: yield ~9–12 slices; total time ~35 minutes; exact ingredient amounts; clear doneness cues (shiny top, few moist crumbs); step-by-step cooling for clean cuts.Swaps: gluten-free (1:1 GF flour), dairy-free (oil + DF chips), egg-free (flax eggs); nut-free by default.Plating: dark, matte cracks with glints of salt—sweet, but it doesn’t apologize. Keep ingredients common and fully home-kitchen accessible."
