Gooey Chocolate Chip Cookie Bars Recipe

Ingredients

• 1 cup (2 sticks) unsalted butter, melted and slightly cooled

• 1 cup packed light brown sugar

• 1/2 cup granulated sugar

• 2 large eggs, room temperature

• 2 tsp vanilla extract

• 2 1/2 cups all‑purpose flour

• 1 tsp baking soda

• 1/2 tsp baking powder

• 3/4 tsp salt

• 2 cups semi‑sweet chocolate chips or chunks (plus extra for the top)

• Optional: 1/2 cup chopped walnuts or pecans

Step 1: Prep the Pan

1. Heat oven to 350°F (175°C).

2. Line a 9×13‑inch baking pan with parchment paper, leaving overhang on the long sides, and lightly grease.

Lining the pan makes it easy to lift out the bars and cut clean squares.

Step 2: Make the Cookie Bar Dough

1. In a large bowl, whisk melted butter, brown sugar, and granulated sugar until smooth and glossy.

2. Whisk in eggs one at a time, then add vanilla.

3. In a separate bowl, whisk flour, baking soda, baking powder, and salt.

4. Add dry ingredients to wet and stir gently just until no dry streaks remain.
