Best Gooey Chocolate Chip Cookies (Print Version)

Chewy chocolate chip cookies with gooey centers, crisp edges, and rich flavor. Walnut option for extra crunch.

# Ingredients:

→ Cookie Dough

01 - 1/2 cup unsalted butter, softened
02 - 3/4 cup packed light brown sugar
03 - 1/4 cup granulated sugar
04 - 1 large egg
05 - 1 tablespoon pure vanilla extract
06 - 2 cups all-purpose flour
07 - 2 tablespoons cornstarch
08 - 1 teaspoon baking powder
09 - 1/2 teaspoon baking soda
10 - 1/2 teaspoon salt
11 - 12 ounces semi-sweet chocolate chips
12 - 1/2 cup walnut pieces (optional)

# Steps:

01 - Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
02 - In a large mixing bowl, beat together the softened butter, light brown sugar, and granulated sugar until the mixture is light and fluffy.
03 - Add in the egg and vanilla extract; beat until thoroughly combined with the creamed mixture.
04 - Add the all-purpose flour, cornstarch, baking powder, baking soda, and salt to the wet ingredients. Mix until just combined, careful not to overwork the dough.
05 - Gently fold in the semi-sweet chocolate chips and walnut pieces, if using, ensuring even distribution throughout the dough.
06 - Scoop the dough into portions of approximately 2 tablespoons each and place on the prepared sheets. For thicker cookies, chill the tray of dough balls for 30 minutes before baking.
07 - Bake in batches for 9 to 11 minutes, until edges are lightly golden but centers remain visibly under-baked for a gooey texture.
08 - Allow cookies to rest on the baking sheet for 5 minutes to finish setting, then transfer to a wire rack to cool completely.

# Notes:

01 - For an extra gooey texture, avoid overbaking; cookies should appear slightly underdone at the center when removed from the oven.
