Ingredients

Scale
  • 1 ยพ cups (220g) all-purpose flour
  • ยฝ teaspoon baking soda
  • ยฝ teaspoon salt
  • ยพ cup (170g) unsalted butter, softened
  • ยพ cup (150g) packed brown sugar
  • ยผ cup (50g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 ยฝ cups (270g) mini semisweet chocolate chips

Instructions

  1. Preheat your oven to 350ยฐF (175ยฐC). Prepare your 9×9-inch pan by lining it with parchment paper, leaving some overhang for easy removal later.
  2. In a medium bowl, whisk together 1 ยพ cups (220g) all-purpose flour, ยฝ teaspoon baking soda, and ยฝ teaspoon salt. Set aside.
  3. In a large bowl, use an electric mixer on medium speed to beat ยพ cup (170g) softened unsalted butter, ยพ cup (150g) packed brown sugar, and ยผ cup (50g) granulated sugar until light and fluffy, about 2-3 minutes.
  4. Beat in 2 large eggs, one at a time, then stir in 2 teaspoons pure vanilla extract. Mix until well combined but do not overbeat.
  5. Gradually add the dry ingredients to the wet, mixing on low speed or folding gently with a spatula until no visible flour remains. Avoid overmixing.
  6. Gently fold in 1 ยฝ cups (270g) mini semisweet chocolate chips for even distribution.
  7. Transfer the dough into your prepared pan, spreading evenly with a spatula and smoothing the top.
  8. Bake for 22-26 minutes. Start checking at 22 minutes; edges should be golden and center set but still soft. A toothpick inserted should come out with a few moist crumbs but not wet batter.
  9. Allow the bars to cool in the pan on a wire rack for at least 30 minutes before slicing.
  10. Using a sharp knife, cut into about 16 squares for mini bars. Store extras in an airtight container.

Notes

Use softened butter (not melted) for best texture. Do not overmix the flour to avoid tough bars. Mini chocolate chips distribute flavor evenly and help prevent crumbling. Start checking baking time early to avoid overbaking. Cooling completely before slicing helps bars firm up and slice cleanly. Chilling dough for 20 minutes before baking can improve texture. Tent with foil if oven runs hot to prevent over-browning.
