Ingredients

1 cup (2 sticks or 226g) unsalted butter, plus a little extra for greasing the pan
2 ½ cups (about 310g) all-purpose flour, spooned and leveled
1 teaspoon baking soda
¾ teaspoon salt (use ½ teaspoon if using salted pistachios)
¾ cup (165g) packed light brown sugar
½ cup (100g) granulated sugar
½ cup (170g) honey (clover or wildflower honey works well)
2 large eggs, at room temperature
2 teaspoons pure vanilla extract
1 ½ cups (about 210g) raw, unsalted shelled pistachios, roughly chopped (reserve ¼ cup for topping, optional)
Flaky sea salt for sprinkling on top (optional, but highly recommended)

Instructions

Step 1: Place the butter in a medium light-colored saucepan and melt over medium heat. Once melted, it will foam and sizzle as water evaporates. Continue cooking, swirling occasionally, until the butter turns amber and smells nutty with golden brown milk solids at the bottom. This takes about 5-8 minutes. Remove from heat and pour into a large heatproof bowl, including the solids. Let cool for 15-20 minutes at room temperature or chill for 10 minutes, stirring occasionally, until cool but still liquid.
Step 2: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan and line it with parchment paper, leaving an overhang on two opposite sides. Lightly grease the parchment as well.
Step 3: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
Step 4: To the cooled brown butter, add the light brown sugar, granulated sugar, and honey. Beat on medium speed with a mixer or whisk for 2-3 minutes until smooth and slightly lightened.
Step 5: Add eggs one at a time, beating well after each addition and scraping down the bowl as needed. Stir in vanilla extract.
Step 6: Gradually add the dry ingredients in three additions, mixing on low or folding gently just until flour is nearly incorporated. Avoid overmixing to keep the bars chewy.
Step 7: Fold in 1 ¼ cups of chopped pistachios gently until evenly distributed.
Step 8: Transfer the dough to the prepared pan and press evenly into the corners and sides. If desired, sprinkle the reserved pistachios and flaky sea salt on top.
Step 9: Bake for 25-30 minutes until edges are set and golden, and the center appears slightly underbaked but not wet. Check around 23 minutes to avoid overbaking for a chewier texture.
Step 10: Cool completely on a wire rack in the pan for at least 2-3 hours before lifting out and cutting to ensure clean bars.
Step 11: Use the parchment overhangs to lift the bars out; cut into desired sizes and enjoy!

Tips & Variations

Use a light-colored pan for browning butter to better monitor the color and avoid burning.
Substitute half the pistachios with toasted almonds or walnuts for a different nutty twist.
For a richer flavor, drizzle a little extra honey over the bars just after baking while still warm.
If you prefer less sweetness, reduce the granulated sugar to ⅓ cup.

Storage

Store these cookie bars in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate up to 1 week or freeze tightly wrapped for up to 3 months. Reheat briefly in a microwave or oven to soften before serving.

FAQs

Can I use salted pistachios instead of unsalted?

Yes, but reduce the added salt in the recipe to ½ teaspoon to balance the flavors and avoid over-salting.

How do I know when the brown butter is ready?

Brown butter is ready when it turns a golden amber color and emits a nutty aroma. You’ll see browned milk solids settling at the bottom of the pan. Remove it immediately to prevent burning.

Ingredients

Scale

Butter and Sugars

1 cup (2 sticks or 226g) unsalted butter, plus extra for greasing the pan
¾ cup (165g) packed light brown sugar
½ cup (100g) granulated sugar
½ cup (170g) honey (clover or wildflower honey recommended)

Dry Ingredients

2 ½ cups (about 310g) all-purpose flour, spooned and leveled
1 teaspoon baking soda
¾ teaspoon salt (use ½ teaspoon if using salted pistachios)

Additional Ingredients

2 large eggs, at room temperature
2 teaspoons pure vanilla extract
1 ½ cups (about 210g) shelled pistachios, raw, unsalted, roughly chopped (reserve ¼ cup for topping, optional)
Flaky sea salt for sprinkling on top (optional but highly recommended)

Instructions

Brown the Butter (The Flavor Foundation): Place the unsalted butter in a medium light-colored saucepan and melt over medium heat. Once melted, the butter will foam and sizzle as water evaporates. Continue cooking and swirling the pan until the butter turns amber and you see golden brown milk solids. This process takes about 5-8 minutes. Remove from heat and pour the browned butter and solids into a large heatproof bowl to cool for 15-20 minutes at room temperature or 10 minutes in the refrigerator, stirring occasionally, until cool but still liquid.
Prepare the Pan and Oven: Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter. Line it with parchment paper leaving an overhang on two opposite sides and lightly grease the parchment as well.
Combine Dry Ingredients: In a medium bowl, whisk together all-purpose flour, baking soda, and salt. Set aside.
Mix Wet Ingredients: To the cooled brown butter, add light brown sugar, granulated sugar, and honey. Beat with an electric mixer or whisk on medium speed for 2-3 minutes until smooth and slightly lightened. Add eggs one at a time, beating well after each addition. Scrape down bowl sides as needed. Beat in vanilla extract until combined.
Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture in three additions, mixing on low speed or stirring gently with a spatula until just incorporated. Avoid overmixing to keep bars chewy.
Fold in Pistachios: Fold in 1 ¼ cups of chopped pistachios using a spatula or wooden spoon until evenly distributed. Reserve ¼ cup for topping if desired.
Press Dough into Pan: Scrape thick, sticky dough into the prepared pan and press evenly into corners using a spoon back, offset spatula, or greased fingertips. Sprinkle remaining pistachios and flaky sea salt on top if using.
Bake to Perfection: Bake on the center rack for 25-30 minutes until edges are golden and set, and center looks slightly underbaked but not wet. A toothpick should come out with moist crumbs. Start checking at 23 minutes for best chewy texture.
Cool Completely (Crucial Step!): Remove pan from oven and cool completely on a wire rack for at least 2-3 hours before cutting. Cooling ensures clean cuts and chewy texture.
Cut and Enjoy: Use parchment overhangs to lift bars out of the pan onto a cutting board. Cut into bars using a sharp knife; recommended grids are 4×6 (24 bars) or 3×5 (15 bars). Wipe knife between cuts for neat edges. Serve and enjoy!

Notes

Using a light-colored pan for browning butter helps monitor the color accurately to prevent burning.
Do not overmix the dough after adding flour to avoid tough, cakey bars.
Cooling the bars completely before cutting is essential for neat slices and optimal chewy texture.
Flaky sea salt topping enhances flavor contrast but is optional.
Honey type impacts flavor—clover or wildflower honey recommended for best results.
