Equipment
Method
Prep
- Preheat the oven to 350F and line a 9x13 pan with parchment so the bars lift out easily after baking.
Make the shortbread base
- Combine all-purpose flour, powdered sugar, cornstarch, and salt, then cut in cold unsalted butter until the dough just comes together, with no dry flour streaks.
- Press the dough firmly and evenly into the lined pan.
- Bake at 350F for 18-20 minutes until pale golden at the edges, then remove the pan.
Make the pecan filling and bake
- Melt unsalted butter, brown sugar, honey, and heavy cream over medium heat until smooth and steaming.
- Bring the mixture to a boil, then cook for 2 minutes, watching for a thickened amber color.
- Remove from the heat and stir in salt, vanilla extract, and whole pecans until the pecans are well coated.
- Pour the hot pecan filling over the hot shortbread, spreading evenly to the edges.
- Bake at 350F for 20-25 minutes until the filling is set and no longer looks loose in the center.
Finish and slice
- Sprinkle flaky sea salt over the warm bars for a salted caramel top.
- Cool completely before slicing so the filling firms up cleanly and holds its shape.
Notes
For the cleanest slices, cool the bars fully (or chill) before cutting; the caramel-pecan filling sets as it cools. Store airtight in the refrigerator for up to 5 days. Freezing is yes: wrap tightly and freeze up to 2 months, then thaw overnight in the fridge. For a lighter swap, use light brown sugar and reduce the heavy cream to 3/16 cup while keeping bake times the same.
