Ingredients

Base 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)

Sugar & Sweeteners

  • Light Brown Sugar: ¾ cup (165g), packed
  • Granulated Sugar: ½ cup (100g)
  • Honey: ½ cup (170g) – Clover or wildflower honey works well

Binding Ingredients

  • Large Eggs: 2, at room temperature
  • Pure Vanilla Extract: 2 teaspoons

Mix-ins & Toppings

  • 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. Brown the Butter: In a medium saucepan, melt the unsalted butter over medium heat. Continue cooking, stirring frequently, until the butter turns golden brown and develops a nutty aroma. This process usually takes about 5-7 minutes. Remove from heat and let it cool slightly.
  2. Preheat the Oven & Prepare Pan: Preheat your oven to 350°F (175°C). Grease or line a baking pan (9×13 inch recommended) with parchment paper for easy removal of bars.
  3. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, and salt until evenly combined.
  4. Combine Sugars and Browned Butter: In a separate bowl, stir together the light brown sugar, granulated sugar, and honey until well mixed. Slowly add the warm browned butter, stirring continuously to incorporate.
  5. Add Eggs and Vanilla: Beat the eggs into the butter-sugar mixture one at a time, followed by the vanilla extract. Mix until smooth and fully blended.
  6. Incorporate Dry Ingredients: Gradually add the flour mixture into the wet ingredients, stirring gently just until combined. Be careful not to overmix to maintain a tender texture.
  7. Fold in Pistachios: Fold in 1 ¼ cups of the roughly chopped pistachios evenly throughout the batter.
  8. Transfer to Pan & Add Toppings: Spread the batter evenly in the prepared baking pan. Sprinkle the reserved ¼ cup pistachios on top along with a light sprinkling of flaky sea salt if using.
  9. Bake: Place in the preheated oven and bake for 25-30 minutes or until the edges are golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
  10. Cool and Serve: Allow the bars to cool completely in the pan on a cooling rack before slicing into squares. Enjoy your Brown Butter and Honey Pistachio Cookie Bars!

Notes

  • Use room temperature eggs for better mixing and texture.
  • Brown the butter carefully to avoid burning – it should smell nutty and look golden, not dark brown or black.
  • Honey adds natural sweetness and moisture; using good quality honey enhances flavor.
  • Flaky sea salt on top contrasts beautifully with the sweetness—don’t skip if you enjoy a hint of saltiness.
  • Store bars in an airtight container at room temperature for up to 4 days or refrigerate for up to a week.
