With a sizable saucepan, merge brown sugar, honey, butter, cream, and salt. Let the mixture reach boiling point, then simmer gently for two minutes. A sweet aroma will fill your kitchen.
Remove the concoction from heat, gracefully mixing in the vanilla and pecans till they're well enveloped in the caramel goodness.
Gently pour this lush filling over the warm crust. A return trip to the oven for about 20-25 minutes will see the filling bubble and adopt a caramelized shade.
Allow the baked delight to cool entirely, preferably on a wire rack.
Once cool, simply lift using the overhanging parchment and place on a cutting board. Slice into elegant 2-inch squares. Best savored at room temperature.
