Ingredients
For the shortbread crust
1cup2 sticks unsalted butter, room temperature
1/2cupgranulated sugar
1/4teaspoonsalt
2cupsall-purpose flour
1teaspoonpure vanilla extract
For the brown sugar caramel pecan topping

2tablespoonshoney or maple syrupfor a deeper flavor
1/2teaspoonsalt
2 1/2cupschopped pecanstoasted for best flavor
1teaspoonvanilla extract
Instructions
Preheat and prep the pan
Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving some overhang on the sides to make it easier to lift out the bars once they’re cooled.
Make the shortbread crust
In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy, about 2-3 minutes. Mix in the vanilla extract and salt. Gradually add the flour, mixing until fully combined. The dough will be soft but not sticky.
Press the shortbread dough evenly into the bottom of the prepared pan. Use your hands or the bottom of a flat measuring cup to press it down evenly. Prick the dough all over with a fork to prevent bubbling.
Bake the crust for 18–20 minutes, or until it’s lightly golden around the edges. Let it cool slightly while you prepare the topping.
Toast the pecans
While the crust is baking, toast the chopped pecans in a dry skillet over medium heat for 3–5 minutes, stirring often until fragrant. This step deepens the flavor of the nuts, making your pecan topping even richer.
Make the brown sugar caramel topping
In a medium saucepan over medium heat, melt the butter. Stir in the brown sugar, heavy cream, honey or syrup, and salt. Bring the mixture to a low boil, stirring constantly for 1–2 minutes until smooth and glossy. Remove from heat and stir in the toasted pecans and vanilla extract.
Assemble and bake
Pour the caramel pecan mixture over the slightly cooled crust, spreading it evenly with a spatula. Bake again at 350°F for about 15–17 minutes, or until the topping is bubbling slightly and set.
Cool and slice
Let the bars cool completely in the pan. For easier slicing, chill them in the fridge for 30 minutes once they've cooled to room temperature. Use the parchment paper overhang to lift them out, and slice into 24 bars.
