Ingredients

1 cup unsalted butter, cut into 16 pieces — For browning into the crust, adds deep nutty flavor.
1/2 cup granulated sugar — Sweetens the crust and helps create a slightly crisp texture.
2 Tablespoons water — Helps dissolve the sugar and bring the crust dough together.
1 teaspoon pure vanilla extract — Adds warm, aromatic flavor.
1/2 teaspoon salt — Balances sweetness and enhances the butter flavor.
2 cups all-purpose flour — Forms the structure of the crust.
1 Tablespoon cornstarch — Keeps the crust tender and helps bind the dough.
1/2 cup pure maple syrup — Primary sweetener for the topping with rich maple notes.
1/2 cup packed light or dark brown sugar — Adds caramel depth to the filling.
6 Tablespoons unsalted butter — Melted into the filling for richness and gloss.
1/4 cup heavy cream — Creates a silky, custardy texture in the topping.
2 large eggs, beaten — Sets the filling and gives a tender custard finish.
3 cups chopped pecans — Provides crunch and true pecan pie character.
Optional: flaky sea salt or coarse sea salt, for sprinkling — Enhances contrast and flavor on top.

Step-by-Step Instructions

Preheat the oven and prepare the pan. Preheat the oven to 350°F (177°C). Line a 9×13-inch metal baking pan with parchment paper so you can lift the bars out easily after baking.
Brown the butter for the crust. In a skillet, melt the 1 cup of unsalted butter over medium heat, stirring constantly until the butter foams and then browns with a nutty aroma. Watch closely so it does not burn. Tip: Swirl the pan and scrape browned bits from the bottom for the most flavor.
Make the crust mixture. Allow the brown butter to cool slightly, then combine it with the granulated sugar, water, vanilla extract, and salt in a bowl; mix well so the sugar is moistened.
Add dry ingredients and press into pan. Add the 2 cups all-purpose flour and 1 Tablespoon cornstarch, mixing until slick and evenly combined. Press the mixture evenly into the prepared pan to form the crust. Use a flat-bottomed measuring cup to tamp it down for an even base.
Bake the crust. Bake the crust for 15 minutes in the preheated oven. Remove from oven and set aside while you prepare the topping.
Make the topping in the same skillet. In the same skillet, combine the 1/2 cup maple syrup, 1/2 cup packed brown sugar, 6 Tablespoons unsalted butter, and 1/4 cup heavy cream over medium heat, whisking until everything melts and is well combined.
Finish the filling off heat. Remove the skillet from heat and cool slightly for a minute. Whisk in the beaten eggs until smooth, then fold in the 3 cups chopped pecans until evenly distributed.
Assemble and bake. Pour the pecan-maple mixture over the par-baked crust, spreading it evenly. Optionally sprinkle flaky sea salt or coarse sea salt on top for contrast. Bake for 25 to 28 minutes, until a toothpick inserted near the center comes out mostly clean. If the top seems to be browning too quickly, cover loosely with foil.
Cool and cut. Cool completely in the pan on a wire rack, then lift the bars out using the parchment paper and cut into squares. Store in an airtight container.
