Ingredients

Dry Ingredients

  • 2 cups (240 g) all purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt

Wet Ingredients

  • ¾ cup (170 g) unsalted butter
  • 1 cup (200 g) light brown sugar
  • ¼ cup (50 g) granulated sugar
  • 1 cup (256 g) creamy peanut butter
  • 2 large eggs, room temperature
  • 1 tablespoon (15 ml) vanilla bean paste

Other

  • 2 cups (340 g) semi sweet chocolate chips, divided

Instructions

  1. Prep: Preheat your oven to 350°F (177°C). Lightly grease a 13 x 9 inch pan and line the bottom and two long sides with parchment paper for easy removal later.
  2. Melt Butter: In a small bowl, melt the unsalted butter. After melting, place the butter in the refrigerator to cool for about 10 minutes to avoid cooking the eggs when mixed.
  3. Mix Dry Ingredients: In a separate mixing bowl, whisk together all-purpose flour, baking soda, and salt until well combined.
  4. Combine Wet Ingredients: In a large bowl, whisk the cooled melted butter with the light brown sugar, granulated sugar, and creamy peanut butter until the mixture is smooth and fully blended. Then whisk in the eggs and vanilla bean paste until the mixture is silky and consistent.
  5. Mix Dry and Wet: Gradually incorporate the dry ingredients into the wet ingredients in two additions, stirring just until combined to avoid overmixing. Gently fold in most of the semi-sweet chocolate chips, reserving about half a cup to sprinkle on top later.
  6. Shape and Bake: Press the cookie dough evenly into the prepared pan using a flexible spatula. Sprinkle the reserved chocolate chips on top. Bake the bars for 22 to 27 minutes or until the edges turn light golden brown, the bars puff slightly, and edges start to pull away from the pan.
  7. Cool: Allow the bars to cool in the pan for 25 to 30 minutes. Once cooled enough to handle, lift the bars out of the pan using the parchment paper overhangs. Transfer to a cooling rack and slice into servings once fully cooled. Enjoy your peanut butter chocolate chip bars!

Notes

  • Use room temperature eggs for better incorporation and texture.
  • Cooling the melted butter prevents scrambling the eggs when mixing.
  • Do not overmix after adding flour to keep the bars tender.
  • Reserve some chocolate chips to enhance the chocolate flavor on top and for visual appeal.
  • Letting the bars cool completely before cutting helps them hold their shape better.
