CRUST: Begin by lining a 9-inch square baking pan and giving it a quick spray using nonstick cooking spray.
Use a food processor to combine flour, cornstarch, confectioners sugar, and salt. Give it a few pulses to blend the dry ingredients.
Add the butter to the mixture and pulse a few more times until texture resembles coarse meal.
No need to worry if the mixture appears dry.
Transfer the combined mixture to the prepared pan. Press it down firmly to create
an even layer.
Place the pan in the refrigerator for approximately 15 minutes.
Meanwhile, preheat your oven to 350°F (175°C).
Once the crust has had its time in the refrigerator, bake it in the preheated oven
for roughly 16 minutes. Our aim is to set the crust without any browning.
Once baked, allow the crust to cool on a rack. Remember to keep the oven on, as we'll be using it again.
FILLING: Put butter, brown sugar, honey, vanilla, and salt in a medium pan over medium-low heat.
Stir with a wooden spoon until the sugar dissolves.
Raise the heat and let it gently boil for around 3 minutes.
Then, add heavy cream and chopped pecans to the mixture.
BAKING: Pour the pecan mixture over the crust (it's okay if the crust is still warm).
Bake for about 20 minutes (until the filling bubbles ).
Let it cool completely.
Cut it into 2-inch squares.
