Ingredients

• Unsalted Butter: 1 cup (2 sticks or 226g), plus a little extra for greasing the pan
• All-Purpose Flour: 2 ½ cups (about 310g), spooned and leveled
• Baking Soda: 1 teaspoon
• Salt: ¾ teaspoon (use ½ teaspoon if using salted pistachios)
• Light Brown Sugar: ¾ cup (165g), packed
• Granulated Sugar: ½ cup (100g)
• Honey: ½ cup (170g) – Clover or wildflower honey works well
• Large Eggs: 2, at room temperature
• Pure Vanilla Extract: 2 teaspoons
• Shelled Pistachios: 1 ½ cups (about 210g), raw, unsalted, roughly chopped (reserve ¼ cup for topping, optional)
• Flaky Sea Salt: For sprinkling on top (optional, but highly recommended)

Instructions

1. Step 1: Place the unsalted butter in a medium-sized, light-colored saucepan and melt over medium heat. Continue cooking, swirling occasionally, until the butter foams, the water evaporates, and the milk solids turn golden brown with a nutty aroma, about 5-8 minutes. Immediately remove from heat and pour into a heatproof bowl including the brown bits. Let cool to room temperature but remain liquid, about 15-20 minutes.
2. Step 2: Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan, line with parchment paper leaving an overhang, and lightly grease the parchment.
3. Step 3: In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
4. Step 4: To the cooled brown butter, add brown sugar, granulated sugar, and honey. Beat on medium speed with an electric mixer or whisk until smooth and slightly lightened, about 2-3 minutes.
5. Step 5: Add eggs one at a time, beating well after each addition. Then beat in vanilla extract.
6. Step 6: Gradually add the dry ingredients in three additions, mixing on low speed or folding gently until just combined. Avoid overmixing to keep bars chewy.
7. Step 7: Fold in 1 ¼ cups of chopped pistachios gently until evenly distributed.
8. Step 8: Press the thick dough evenly into the prepared pan, reaching all corners. Sprinkle reserved pistachios and flaky sea salt on top if using.
9. Step 9: Bake for 25-30 minutes until edges are golden and center is slightly underbaked but not wet. Check for doneness starting at 23 minutes; a toothpick should come out with moist crumbs.
10. Step 10: Cool completely in the pan on a wire rack for at least 2-3 hours. Use parchment overhangs to lift out and cut into bars before serving.

Tips & Variations

• Toast pistachios beforehand for enhanced flavor and crunch.
• Use the spoon and level method or a kitchen scale for measuring flour to avoid dense bars.
• Bring eggs to room temperature to ensure smooth incorporation.
• Do not cut bars while warm to prevent crumbling and messy edges.
• Substitute pistachios with toasted walnuts, pecans, almonds, hazelnuts, or cashews.

Storage

Store the cookie bars in an airtight container at room temperature for up to 4 days. For longer storage, wrap bars tightly and freeze for up to 3 months. Thaw at room temperature or warm briefly in the microwave before serving.

FAQs

Can I use salted butter instead of unsalted?

Yes, but reduce the added salt to about ½ teaspoon or less to avoid oversalting. Unsalted butter is preferred for control over saltiness.

My bars seem greasy. What might be the cause?

This can happen if the brown butter was too warm when mixing or if ingredient measurements were off. Ensure the butter is cooled to liquid but not warm, measure ingredients accurately, and allow bars to cool fully before assessing texture.

Can I make these gluten-free?

Yes, substitute the all-purpose flour with a good measure-for-measure gluten-free flour blend containing xanthan gum. Baking time may vary slightly.

Can I freeze the dough or the baked bars?

Yes. Freeze dough pressed in the pan wrapped tightly for up to 3 months; bake from frozen, adding 5-10 minutes. Freeze baked bars individually wrapped for up to 3 months; thaw before serving.

Can I use other nuts instead of pistachios?

Absolutely. Toasted walnuts, pecans, almonds, hazelnuts, or cashews work well. Keep the total nut volume about 1 ½ cups.

Ingredients

Scale 1x2x3x

Butter & Sugars

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

Other 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 recommended)

Instructions

1. Brown the Butter (The Flavor Foundation): Melt 1 cup of unsalted butter in a medium light-colored saucepan over medium heat, swirling occasionally. Once melted, the butter will foam and sizzle as water evaporates. Continue cooking until golden brown specks form at the bottom and the butter turns amber with a nutty aroma (approx. 5-8 minutes). Remove from heat and pour all browned butter and milk solids into a large heatproof bowl. Let cool 15-20 minutes at room temperature or 10 minutes refrigerated until cool but still liquid.
2. Prepare the Pan and Oven: Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan with extra butter, line with parchment paper leaving an overhang on two opposite sides, and lightly grease the parchment.
3. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, and salt to evenly distribute the leavening agent and aerate the flour. Set aside.
4. Mix Wet Ingredients: To the cooled browned 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, scraping bowl sides as needed. Beat in vanilla extract until combined.
5. Combine Wet and Dry Ingredients: Gradually add dry ingredients in three additions, mixing on low or folding with a spatula just until flour is almost incorporated each time. Avoid overmixing to prevent tough bars.
6. Fold in Pistachios: Gently fold in 1 ¼ cups of chopped pistachios using a spatula or wooden spoon until evenly distributed. Reserve remaining pistachios for topping if desired.
7. Press Dough into Pan: Scrape sticky dough into prepared pan. Press evenly into corners and level the surface using a spatula, spoon back, or greased fingertips. Sprinkle reserved pistachios and flaky sea salt on top if using.
8. Bake to Perfection: Bake on center rack for 25-30 minutes. Edges should be set and golden; center slightly underbaked but not wet or jiggly. Insert toothpick to check for moist crumbs with no wet batter. Start checking at 23 minutes and err on underbaking for chewier bars.
9. Cool Completely (Crucial Step!): Remove pan from oven and cool on wire rack. Let bars cool in pan at least 2-3 hours to set fully for clean cutting and perfect chewy texture. Cutting warm bars causes crumbly, messy pieces.
10. Cut and Enjoy: Lift bars out using parchment overhangs onto a cutting board. Cut into desired size (24 bars in 4×6 grid or 15 larger bars in 3×5 grid). Clean knife between cuts for neat edges. Serve and enjoy!

Notes

• Brown the butter carefully to achieve a deep amber color and nutty aroma without burning; pour out immediately after browning to stop cooking.
• Use the spoon and level method or a kitchen scale for measuring flour to avoid dense or dry bars.
• Use room temperature eggs to ensure smooth emulsification and consistent batter texture.
• Allow bars to cool completely before cutting to maintain structure and avoid crumbling.
• Optional: Toast pistachios at 350°F for 5-7 minutes before chopping to enhance flavor and crunch.
• Salt adjustment: If using salted butter, reduce added salt to ½ teaspoon or less to prevent over-salting.
• Bars can be frozen either raw in pan (covered well) or baked bars (individually wrapped) for up to 3 months.
• Substitute pistachios with other nuts like toasted pecans, walnuts, almonds, hazelnuts, or cashews for variety.
