Ingredients

Scale

Wet Ingredients

  • 1 cup unsalted butter
  • 2 cups packed brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract

Dry Ingredients

  • 3 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt

Add-ins

  • 1 cup chocolate chips
  • 1 cup unsalted pistachios, chopped

Instructions

  1. Brown the Butter: In a medium saucepan, melt the butter over medium heat until it starts to froth. Continue cooking for about 5-7 minutes until the butter turns golden brown and releases a nutty aroma. Remove from heat and let it cool slightly.
  2. Mix It Up: In a large mixing bowl, combine the browned butter and brown sugar. Whisk thoroughly until the mixture is smooth. Add eggs one at a time, whisking to fully incorporate each, then mix in the vanilla extract.
  3. Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined to avoid overmixing.
  4. Add the Goodies: Fold in the chocolate chips and chopped pistachios evenly into the cookie dough using a spatula.
  5. Prepare the Pan: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper for easy removal.
  6. Spread and Bake: Pour the cookie dough into the prepared baking pan and spread it evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until the edges turn golden brown and a toothpick inserted into the center comes out clean.
  7. Cool and Slice: Allow the bars to cool in the pan for about 10 minutes. Then remove them from the pan, transfer to a wire rack to cool completely before slicing into squares.

Notes

  • For a deeper nutty flavor, make sure to watch the butter carefully as it brown to prevent burning.
  • Use parchment paper to help lift bars easily from the pan after baking.
  • You can substitute semi-sweet chocolate chips with dark or milk chocolate based on preference.
  • Store bars in an airtight container at room temperature for up to 5 days or freeze for longer storage.
