A gooey brown butter skillet cookie with malted milk powder and melty chocolate pools, baked for one big communal spoon-dessert.
Pull the cookie when the center still jiggles slightly — cast iron keeps cooking it after the oven, so waiting for a clean toothpick guarantees a dry, cakey result instead of a gooey one. Use a torn chocolate bar, not chips, for real melty pools. No malted milk powder? Skip it or use Ovaltine/Horlicks — the cookie still works, just with less depth.
