Brown Butter and Honey Pistachio Cookie Bars

Featured in Irresistible Desserts.

These Brown Butter and Honey Pistachio Cookie Bars take the humble cookie bar to new heights with sophisticated flavors and minimal effort. The magic starts with browning the butter, a simple technique that transforms ordinary butter into something extraordinary with deep, nutty notes. Combined with honey and brown sugar, this creates a rich, caramel-like base that's simultaneously complex and comforting. The flaky sea salt sprinkled throughout enhances all the flavors, creating that irresistible sweet-salty balance that keeps you coming back for just one more bite. The roughly chopped pistachios add both visual appeal and textural contrast, with their distinctive color and satisfying crunch. What makes these bars truly special is how easily they come together - you don't need any special equipment or techniques beyond browning the butter. They're fancy enough for gifting or serving to guests but simple enough for a weeknight treat. The bars also strike that perfect texture balance: slightly crisp edges with a soft, almost blondie-like center that stays moist thanks to the honey.

These brown butter and honey pistachio cookie bars deliver an irresistible combination of nutty, caramelized brown butter, floral honey sweetness, and the perfect salty crunch from pistachios. Unlike traditional cookie bars that can often be one-dimensional in flavor, these bars offer a sophisticated taste experience with layers of complexity in every bite.

I developed this recipe after craving something that would showcase the beautiful complexity of honey beyond just its sweetness. After four test batches (and a few disappointing over-baked attempts), I finally landed on this perfect version.

Simple Ingredients

  • 10 tablespoons unsalted butter: Creates rich, nutty foundation when browned
  • 1 cup packed light brown sugar: Adds caramel notes and perfect chewiness
  • 3½ tablespoons honey: Provides floral sweetness and moisture
  • 1 large egg + 1 large egg yolk: Creates the perfect tender, chewy texture
  • 1¼ teaspoons flaky sea salt: Enhances every flavor while adding delightful contrast

The quality of your honey significantly impacts the final flavor of these bars. I recommend using a high-quality, pure honey with a flavor profile you enjoy, as its character will shine through in the finished bars.

Simple Preparation

Browning the Butter:
Melt butter over medium-low heat until nutty and amber-colored (3-5 minutes). Watch carefully to avoid burning.
Creating the Base:
Mix browned butter with brown sugar and honey. Cool slightly, then whisk in eggs until light and thick.
Incorporating Dry Ingredients:
Fold in flour and most of the salt just until combined. Batter should be thick but pourable.
Baking Preparation:
Pour into lined 8×8 pan. Top with pistachios and remaining salt. Bake at 325°F for 23-25 minutes.
Baking and Cooling:
Bars are done when edges are set but center looks slightly soft. Cool completely before cutting.

I've made countless cookie bar recipes, but these remain my absolute favorite for their perfect balance of flavors and textures.

These brown butter and honey pistachio cookie bars have become my signature dessert – the one friends request for gatherings and the recipe people most often ask for after tasting them.

Frequently Asked Questions

→ How do I know when my butter is properly browned?
Watch for the butter to turn a light amber color and give off a nutty aroma. The milk solids at the bottom of the pan will be golden brown. It happens quickly, so stay close and remove from heat immediately when you see these signs to prevent burning.
→ Can I use unsalted pistachios instead?
Yes, you can use unsalted pistachios, but you might want to increase the flaky sea salt by an extra ¼ teaspoon to maintain the sweet-salty balance that makes these bars special. The contrast between the sweet base and salty topping is part of their charm.
→ How do I get clean cuts when slicing the bars?
Make sure the bars are completely cooled before cutting. Use a sharp knife and wipe it clean between cuts. For extra-clean edges, refrigerate the bars for 30 minutes before cutting, or freeze briefly for about 10 minutes.
→ Can I substitute another type of nut?
Absolutely! Chopped walnuts, pecans, or almonds would all work well in this recipe. Each will bring its own unique flavor profile to the bars while maintaining that wonderful textural contrast.
→ How can I tell when the bars are properly baked?
Look for golden brown edges that appear set, while the center may still look slightly soft. Don't overbake - they'll continue to set as they cool. A toothpick inserted near the center should come out with a few moist crumbs, not completely clean or wet with batter.

Difficulty: Intermediate

Cuisine: American

Yield: 16 Servings (16 small squares)

Dietary: Vegetarian

Ingredients

→ For the cookie base

01 10 tablespoons unsalted butter
02 1 cup packed light brown sugar
03 3½ tablespoons honey (quality honey makes a difference)
04 1 large egg
05 1 large egg yolk
06 1 cup all-purpose flour

→ For topping and flavor

07 1¼ teaspoons flaky sea salt, divided
08 ¼ cup shelled salted pistachios, roughly chopped

Instructions

Step 01

Preheat your oven to 325°F. Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. Lightly spray the parchment and any exposed parts of the pan with non-stick spray.

Step 02

Place the butter in a small saucepan over medium-low heat. Let it melt completely, then continue cooking while swirling occasionally. Watch carefully as the butter foams and the milk solids begin to turn golden brown and smell nutty. Remove from heat as soon as it turns light amber - don't let it get too dark!

Step 03

In a large bowl, combine the browned butter (still warm is fine), brown sugar, and honey. Mix until smooth and well blended. Add the whole egg and the extra yolk, then whisk until the mixture is completely combined.

Step 04

Sprinkle 1 teaspoon of the flaky sea salt over the mixture, then add all of the flour. Stir just until combined and no dry flour remains visible. Be careful not to overmix - this keeps the bars tender!

Step 05

Pour the batter into your prepared baking pan and spread it evenly into the corners. Sprinkle the remaining ¼ teaspoon of flaky salt and all of the chopped pistachios evenly over the top.

Step 06

Bake in the preheated oven for 23-25 minutes. You're looking for golden edges that are set, while the center should still be slightly soft. The top should be golden brown with a slight crackle.

Step 07

Allow the bars to cool in the pan for about 10 minutes, then use the parchment paper overhang to lift them out onto a cooling rack. Let them cool completely before cutting into squares. This helps them set up properly and makes for cleaner cuts.

Notes

  1. These bars will keep in an airtight container at room temperature for up to 3 days.
  2. The browned butter is key to the rich, nutty flavor - don't skip this step!
  3. For a fun variation, try adding a handful of white chocolate chips to the batter.
