Dry Ingredients
- 2 and 1/4 cups (281g) all-purpose flour (spooned & leveled)
- 1 teaspoon baking soda
- 1 and 1/2 teaspoons cornstarch
- 1/2 teaspoon salt
Wet Ingredients
- 3/4 cup (170g/12 Tbsp) unsalted butter, melted & cooled for 5 minutes
- 3/4 cup (150g) packed light or dark brown sugar
- 1/2 cup (100g) granulated sugar
- 1 large egg + 1 egg yolk, at room temperature
- 2 teaspoons pure vanilla extract
Add-ins
- 1 and 1/4 cups (225g) semi-sweet chocolate chips or chocolate chunks
Instructions
- Combine Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, cornstarch, and salt. Set this mixture aside while you prepare the wet ingredients.
- Mix Wet Ingredients: In a medium bowl, whisk the melted and slightly cooled butter with both the brown sugar and granulated sugar until smooth and lump-free. Next, whisk in the egg and egg yolk until fully incorporated. Add the vanilla extract and mix well. The resulting batter will be thin at this stage.
- Combine Wet and Dry: Pour the wet mixture into the bowl with the dry ingredients. Using a large spoon or spatula, mix gently until just combined. The dough will be very soft, thick, and shiny.
- Fold in Chocolate Chips: Gently fold in the semi-sweet chocolate chips or chunks. Note that because of the melted butter, some chips may not stick immediately but do your best to distribute them evenly throughout the dough.
- Chill Dough: Cover the dough tightly with plastic wrap and refrigerate for at least 2 hours, up to 3 days. Chilling overnight is ideal to prevent the cookies from spreading too much during baking.
- Prepare for Baking: Preheat your oven to 325°F (163°C). Line large baking sheets with parchment paper or silicone mats. If the dough has chilled longer than 2 hours, let it rest at room temperature for about 15 minutes to soften slightly.
- Scoop and Shape Cookies: Using a cookie scoop or tablespoon, portion the dough into balls—about 3 scant tablespoons (60g) for extra-large cookies or 2 heaping tablespoons (50g) for medium-large cookies. Roll each ball into a tall cylinder shape with your fingers, rather than a flat disc, to promote thicker cookies.
- Arrange on Baking Sheets: Place the shaped cookie dough balls approximately 3 inches apart on the prepared baking sheets. This spacing allows room for the cookies to spread without merging.
- Bake Cookies: Bake in the preheated oven for 13–14 minutes, until the edges are just lightly browned. The centers will appear soft and underbaked but will firm up as the cookies cool.
- Cool Cookies: Allow the cookies to cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely. For a prettier presentation, you can optionally press a few extra chocolate chips onto the warm tops of the cookies.
- Storage: Store the fully cooled cookies in an airtight container at room temperature for up to one week to maintain freshness and chewiness.
Notes
- Using melted butter and extra brown sugar helps create the chewy, soft texture characteristic of these cookies.
- Cornstarch contributes to a tender crumb and thickness in the cookies.
- Adding an extra egg yolk adds moisture and chewiness.
- Chilling the dough is essential to prevent cookies from spreading too thinly, resulting in thicker, chewier cookies.
- If the dough becomes too firm after extended chilling, allow it to sit at room temperature for 10–15 minutes before shaping.
- Pressing a few extra chocolate chips onto warm cookies is purely for aesthetic appeal and enhances chocolate flavor.
