Ingredients
Method
Preparation
- Melt the butter over medium heat. Once melted, it will start to foam and sizzle.
- Continue cooking, swirling the pan occasionally. The butter will turn clear, then start browning with golden specks.
- Remove from heat once you achieve an amber color and nutty aroma. Pour into a heatproof bowl and let cool for 15-20 minutes.
- Grease a 9×13 inch baking pan and line with parchment paper, leaving an overhang.
- Using an electric mixer, beat the cooled brown butter with sugars until smooth and slightly lightened.
- Add eggs one at a time, beating well after each addition. Then mix in vanilla extract.
- Gently fold in the chopped pistachios using a rubber spatula.
- Press the dough evenly into the baking pan, leveling the surface.
- Sprinkle reserved pistachios and flaky sea salt on top, if desired.
Baking
- Bake for 25-30 minutes until edges are golden brown and center is set.
- Allow to cool completely in the pan for 2-3 hours before lifting out and cutting into bars.
Notes
These bars are forgiving and perfect for potlucks. Let cool completely for clean cuts.
