Ingredients

Scale
  • 1 cup (226g) unsalted butter
  • 2 ½ cups (310g) all-purpose flour (spooned and leveled)
  • 1 teaspoon baking soda
  • ¾ teaspoon salt (use ½ tsp if using salted pistachios)
  • ¾ cup (165g) light brown sugar, packed
  • ½ cup (100g) granulated sugar
  • ½ cup (170g) honey (clover or wildflower)
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 ½ cups (210g) shelled pistachios, roughly chopped (reserve ¼ cup for topping)
  • Flaky sea salt, for sprinkling (optional)

Instructions

  1. Brown the Butter:
    Melt butter in a light-colored saucepan over medium heat. Continue cooking until golden brown specks form and butter smells nutty (about 5–8 minutes). Remove from heat and pour into a large bowl. Cool 15–20 minutes.
  2. Prep the Pan:
    Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan and line with parchment paper, leaving overhang on two sides.
  3. Mix Dry Ingredients:
    Whisk together flour, baking soda, and salt. Set aside.
  4. Mix Wet Ingredients:
    Beat cooled brown butter with brown sugar, granulated sugar, and honey until smooth (2–3 minutes). Add eggs one at a time, mixing well after each. Stir in vanilla.
  5. Combine:
    Gradually mix dry ingredients into wet ingredients until just combined. Do not overmix.
  6. Add Pistachios:
    Fold in 1 ¼ cups chopped pistachios.
  7. Press & Top:
    Press dough evenly into prepared pan. Sprinkle remaining pistachios and flaky sea salt on top if desired.
  8. Bake:
    Bake 25–30 minutes until edges are golden and center is set but slightly soft. A toothpick should come out with moist crumbs.
  9. Cool Completely:
    Cool in pan 2–3 hours before lifting out and slicing.

Notes

  • Do not overmix the dough to keep bars chewy.
  • Slightly underbake for the best texture.
  • Store in an airtight container at room temperature for up to 4 days.
  • Bars freeze well for up to 3 months.
  • Flaky sea salt enhances the honey flavor beautifully.
