Preheat oven to 175°C (350°F), line a rectangular pan with parchment, leaving slight overhang for easy lifting.
Cream butter and brown sugar until light. Add flour and salt; blend until crumbly. Press mixture into the pan and bake until lightly golden, about 15 minutes.
Meanwhile, combine butter, honey, and sugar in a saucepan. Heat gently until the mixture bubbles, then remove from heat. Add cream and vanilla; stir carefully.
Whisk eggs in a bowl, gradually add warm syrup, then fold in chopped pecans.
Pour the filling over the baked crust, spread evenly, and return to the oven. Bake until center is set and edges darken slightly, approximately 25–30 minutes.
Cool completely before slicing into bars for clean edges and firm texture.
