Ingredients

Scale

Main Ingredients:

  • 2 cups all-purpose flour
  • 1 cup unsalted butter
  • 2 cups chocolate chips
  • 2 large eggs

Supporting Sweet Ingredients:

  • ¾ cup granulated sugar
  • ¾ cup brown sugar
  • 2 teaspoons vanilla extract

Leavening and Seasoning:

  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup chopped nuts (optional)

Instructions

  1. Prepare your workspace by heating the oven to 350°F and coating a 9×13-inch baking pan with cooking spray.
  2. Blend 2 cups flour, 1 tsp baking soda, and ½ tsp salt in a medium mixing bowl.
  3. Microwave 1 cup butter in 30-second bursts until completely melted.
  4. Whisk ¾ cup granulated and ¾ cup brown sugars into the warm butter until smooth.
  5. Crack 2 eggs into the butter mixture, stirring thoroughly after each egg. Add 2 tsp vanilla extract.
  6. Fold dry ingredients into wet ingredients gently, stopping when barely combined.
  7. Incorporate 2 cups chocolate chips and ½ cup nuts (if using), stirring until evenly distributed.
  8. Transfer batter to prepared pan, smoothing the surface with a spatula.
  9. Bake for 22-25 minutes at 350°F, watching for golden edges and a firm center.
  10. Remove from oven and let pan rest for 15 minutes.
  11. Slice into rectangular bars while warm, then allow to cool completely before serving.

Notes

  • Use room temperature eggs for smoother batter incorporation and consistent texture.
  • Measure flour correctly by spooning it into the measuring cup and leveling with a knife to prevent dense, dry bars.
  • Melt butter slowly in the microwave to avoid overheating, which can change the final cookie texture.
  • Add chocolate chips after mixing dry and wet ingredients to ensure they don’t sink to the bottom during baking.
