Instructions

1. Step 1: Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, letting excess hang over the edges for easy removal.
2. Step 2: In a large microwave-safe bowl, melt 1 cup unsalted butter for about 1 minute until fully melted and slightly cooled.
3. Step 3: Add 1 1/4 cups packed brown sugar and 1/4 cup granulated sugar to the melted butter and whisk vigorously until smooth and combined.
4. Step 4: Beat in 2 large eggs, one at a time, then stir in 2 tsp vanilla extract until the mixture is glossy.
5. Step 5: In a separate bowl, whisk together 2 1/4 cups all-purpose flour, 1 tsp baking soda, and 1/2 tsp salt.
6. Step 6: Gradually add the dry ingredients to the wet mixture, stirring gently just until no flour streaks remain to avoid overmixing.
7. Step 7: Fold in 1 1/2 cups semi-sweet chocolate chips evenly.
8. Step 8: Pour the dough into the prepared baking pan, spreading it evenly with a spatula.
9. Step 9: Bake for 25-28 minutes until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
10. Step 10: Let the bars cool completely in the pan on a wire rack before lifting them out using the parchment paper and slicing into 12 squares.
