These honey pistachio treats with brown butter give you an amazing mix of caramelized nutty flavor, sweet honey notes, and that satisfying salty crunch from the pistachios. While many standard bar cookies can be pretty basic in taste, these offer something way more interesting with different flavor levels in every mouthful.
I came up with this when I wanted something that would really show off honey's amazing depth beyond just sweetness. It took me four tries (and a couple of sad batches that stayed in the oven too long) before I got this version just right.
Basic Ingredients
- 10 tablespoons unsalted butter: Turns into the nutty, rich base when browned
- 1 cup packed light brown sugar: Brings in those lovely caramel hints and chewiness
- 3½ tablespoons honey: Adds flowery sweetness and keeps everything moist
- 1 large egg + 1 large egg yolk: Makes for that perfect soft, chewy bite
- 1¼ teaspoons flaky sea salt: Boosts all the tastes while adding a nice contrast
Your honey choice really changes how these bars turn out. Try to grab a good, pure honey with a taste you really like, since that flavor will come through clearly in your finished treats.
Easy Steps
- Browning the Butter:
- Let butter melt on medium-low until it smells nutty and turns amber (about 3-5 minutes). Keep an eye on it so it doesn't burn.
- Creating the Base:
- Stir the browned butter with brown sugar and honey. Let it cool a bit, then beat in eggs until it looks light and thick.
- Incorporating Dry Ingredients:
- Gently mix in flour and most of the salt just enough to combine. Your batter should be thick but still pourable.
- Baking Preparation:
- Dump into a lined 8×8 pan. Sprinkle pistachios and leftover salt on top. Pop it in at 325°F for 23-25 minutes.
- Baking and Cooling:
- They're done when the edges look set but the middle seems a bit soft. Let them cool all the way before you cut them.

Frequently Asked Questions
- → How can I tell when the butter is browned?
- It'll turn golden with an amber tint and smell nutty. Check the bottom for golden bits. Watch closely and pull it off the heat as soon as it’s ready!
- → Can I swap salted pistachios for unsalted?
- Sure! If you use unsalted pistachios, sprinkle in a bit more flaky sea salt—around ¼ teaspoon—to keep that great sweet-salty balance.
- → How can I get clean cuts when slicing?
- Wait until the bars cool down completely. Use a sharp knife, wiping it clean after each cut. Chilling the bars first can also help; just pop them in the fridge or freezer for a bit.
- → Can I use a different nut instead?
- Definitely. Walnuts, pecans, or almonds would all fit perfectly, each giving a unique flavor while still adding crunch.
- → How do I know the bars are baked just right?
- Look for the edges to turn golden and firm up, while the center stays ever-so-slightly soft. A toothpick should come out with moist crumbs, not completely dry or wet.
