Ingredients

• Unsalted butter: one of the keys to flavor here as browning it brings out deep caramel notes choose good quality fresh butter
• All-purpose flour: for structure and texture spoon and level it for accuracy
• Baking soda: for gentle leavening making bars tender but not cakey
• Salt: balances sweetness choose less if your pistachios are salted already
• Light brown sugar: adds moisture and a mild caramel undertone
• Granulated sugar: for crunch and sweetness contrast
• Honey: ideally clover or wildflower for floral sweetness and moisture
• Large eggs: at room temperature to bind and enrich the batter
• Pure vanilla extract: for added aroma and flavor depth
• Raw unsalted shelled pistachios: roughly chopped for nutty crunch and visual appeal reserve some for topping
• Flaky sea salt: optional but wonderful on top to highlight the sweet and nutty flavors

Step-by-Step Instructions

Sauté the Butter:

Place the unsalted butter in a medium light-colored saucepan over medium heat. Melt completely and then continue cooking while swirling the pan occasionally until the sizzling slows and the milk solids turn a golden brown color. This usually takes about 5 to 8 minutes after the butter has melted. Quickly transfer the browned butter to a large heatproof bowl stopping the cooking process.

Cool the Browned Butter:

Let the browned butter cool at room temperature for 15 to 20 minutes or chill it in the refrigerator for about 10 minutes. Stir occasionally so it cools evenly and is liquid but cool to the touch before proceeding.

Prepare the Baking Pan:

Set the oven temperature to 175 degrees Celsius or 350 degrees Fahrenheit. Grease a 23 by 33 cm baking pan generously with butter. Line the pan with parchment paper leaving an overhang on two sides to make removing the bars easier later. Lightly grease the parchment paper to prevent sticking.

Mix the Dry Ingredients:

In a medium bowl whisk together the all-purpose flour baking soda and salt until combined and aerated. This ensures even distribution of the leavening agent.

Combine Sugars Honey and Eggs:

Add the light brown sugar granulated sugar and honey to the cooled browned butter. Beat or whisk vigorously for 2 to 3 minutes until the mixture is smooth and lightened in color. Incorporate the eggs one at a time beating well after each addition. Then add the vanilla extract and mix to combine.

Add Dry Ingredients:

Add the dry flour mixture to the wet ingredients in three parts mixing gently on low speed or folding with a spatula. Mix only until the large flour streaks disappear to keep the bars tender.

Fold in Pistachios:

Gently fold in 175 grams of the roughly chopped pistachios into the dough using a spatula or wooden spoon. Reserve the remaining pistachios for topping.

Transfer and Decorate:

Spoon the thick sticky dough into the prepared pan and spread evenly to fill the corners and level the surface using an offset spatula or greased fingertips. Sprinkle the reserved pistachios over the top and add flaky sea salt if desired.

Bake the Bars:

Place the pan on the center oven rack and bake for about 25 to 30 minutes. The bars are done when the edges are golden brown and set while the centre looks slightly underbaked but not wet. A toothpick inserted should come out with moist crumbs and not wet batter.

Cool Completely:

Place the pan on a wire rack and let the bars cool completely for at least 2 to 3 hours. This cooling step is essential for clean cuts and achieving the perfect chewy texture.

Cut and Serve:

Use the parchment paper overhangs to lift the slab gently out of the pan onto a cutting board. Cut into bars of your desired size using a sharp knife wiping the blade between cuts to keep edges neat. Serve and enjoy.

Save

Storage Tips

Store these bars tightly wrapped in an airtight container at room temperature for up to three days. For longer storage wrap tightly in plastic wrap and freeze up to three months. Thaw bars fully before serving to regain the best chewy texture.

Ingredient Substitutions

You can swap pistachios with other nuts such as almonds or walnuts if needed though it will change the flavor profile slightly. If clover or wildflower honey is unavailable use a good quality local honey. For a richer taste you can use a combination of light and dark brown sugar.

Serving Suggestions

These bars pair beautifully with a cup of strong coffee or a creamy chai tea. For a dessert twist a scoop of vanilla ice cream on warm bars is heavenly. They also make a perfect portable snack for picnics or lunchboxes.

Cultural Context

Brown butter is a classic technique in European and American baking renowned for transforming simple recipes with its intense nutty flavor. Honey has been used for millennia as a natural sweetener and also lends depth and moisture to baked goods. Pistachios offer a vibrant contrast well appreciated in Mediterranean cuisine. Together these ingredients create a dessert that feels both timeless and sophisticated.

Pro Tips

Make sure the butter reaches a golden brown color but watch carefully to avoid burning. Letting the browned butter cool fully is crucial or the eggs may scramble when added. Avoid overmixing once the flour goes in to keep the bars tender and chewy.
