Description

These Dark Chocolate & Pistachio Cookie Bars are a delightful treat combining the rich flavors of dark chocolate with the crunchy texture of pistachios. Perfectly soft, chewy, and packed with flavor, these bars are ideal for sharing at gatherings or enjoying as a special dessert.


Ingredients

Cookie Bars

  • 2 1/4 cups dark brown sugar (packed)
  • 3/4 cup butter (softened)
  • 1 tablespoon vanilla bean paste
  • 2 eggs
  • 2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1 cup shelled pistachios
  • 1 cup dark chocolate chips
  • 1/2 teaspoon coarse sea salt (optional)

Topping

  • Melted dark chocolate chips (for drizzling)
  • Caramel sauce (for drizzling)


Instructions

  1. Preheat and prepare pan: Heat the oven to 350°F (175°C). Grease the bottom and sides of a 13×9-inch baking pan using shortening or cooking spray to prevent sticking.
  2. Mix wet ingredients: In a large bowl, beat together the dark brown sugar, softened butter, vanilla bean paste, and eggs using an electric mixer on medium speed, or stir well with a spoon until smooth and combined.
  3. Add dry ingredients and mix: Gradually stir in the all-purpose flour and baking powder until the batter is well blended and smooth, ensuring no dry flour pockets remain.
  4. Incorporate pistachios and chocolate chips: Fold in the shelled pistachios and 1 cup of dark chocolate chips evenly throughout the batter. Optionally, add the coarse sea salt to enhance flavor.
  5. Spread and bake: Evenly spread the cookie batter in the prepared baking pan. Bake in the preheated oven for 20 to 25 minutes or until the edges turn golden brown and the center is set.
  6. Cool and decorate: Remove the pan from the oven and allow the cookie bars to cool completely on a wire rack for about 1 hour.
  7. Drizzle toppings: Once cooled, drizzle melted dark chocolate chips and caramel sauce over the top. Let the drizzle set before cutting.
  8. Cut and serve: Cut the bars into 6 rows by 6 rows (total of 36 bars). Serve and enjoy!

Notes

  • For best results, use unsalted butter to control the salt level in the recipe.
  • Allow the bars to cool fully before cutting to maintain clean edges.
  • You can substitute dark chocolate chips with semi-sweet or milk chocolate if preferred.
  • Adding the optional coarse sea salt enhances the sweet and salty flavor profile.
  • Store bars in an airtight container at room temperature for up to 4 days or refrigerate for longer freshness.
