No candy thermometer required—this fuss-free method simmers everything in one saucepan, so even novice bakers can nail the silky topping on the first try. The finished squares stay fresh for a week in the fridge or a month in the freezer, making them a smart make-ahead treat for busy schedules.
All-purpose flour – 1 cup
Preheat the oven to 350°F / 180°C
Toast the pecans in a dry skillet first; it deepens their flavor and keeps them crisp once embedded in the fudge. For a sweet–salty edge, finish the warm topping with a light pinch of flaky sea salt and press a few whole pecan halves on top before chilling.
