Ingredients
Wet Ingredients
- 1 cup unsalted butter
- 1 cup light brown sugar, packed
- 1/2 cup granulated sugar
- 1 teaspoon pure vanilla extract
- 2 large egg yolks
- 1 large egg
Dry Ingredients
- 2 1/2 cups all-purpose flour
- 1 tablespoon cornstarch
- 1 teaspoon baking soda
- 1/2 teaspoon salt
Add-ins
- 1/2 cup butterscotch chips
- 1/2 cup semi-sweet chocolate chips
Finishing
- Flaky sea salt, for sprinkling
Instructions
- Brown the Butter: Warm the unsalted butter in a large skillet over medium heat, stirring constantly. The butter will foam and after a few minutes, you'll notice a nutty aroma and brown bits forming at the bottom of the pan. This browning process enhances the flavor of the cookies.
- Cool and Combine Wet Ingredients: Pour the browned butter into a mixing bowl, scraping any brown bits from the skillet with a spatula. Let it cool for about 5 minutes. Then whisk in the light brown sugar, granulated sugar, and vanilla extract until fully combined, about 2 minutes. Add the egg and egg yolks, whisking until smooth and incorporated.
- Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt until evenly combined.
- Combine Wet and Dry Ingredients: Gently fold the dry ingredients into the butter-sugar mixture until roughly halfway combined. Add in the butterscotch chips and semi-sweet chocolate chips, then mix just until no flour streaks remain; avoid overmixing to keep the cookies tender.
- Chill the Dough: Cover the bowl tightly with plastic wrap and chill the dough in the refrigerator for at least one hour to improve texture and flavor development.
- Preheat and Prepare for Baking: Preheat the oven to 325°F (160°C). Line two baking sheets with parchment paper to prevent sticking and promote even baking.
- Portion the Cookies: Use a 1/4 cup scoop to portion the dough, spacing the cookies about 3 inches apart on the baking sheets. This will yield 12 large cookies. Alternatively, use a 2 tablespoon scoop and space cookies 2 inches apart for approximately 24 standard-sized cookies.
- Bake: Bake the cookies for 10-13 minutes for the large size, or 9-11 minutes for the smaller size. The edges should be lightly golden while the centers remain slightly underbaked to ensure chewiness.
- Cool and Finish: Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. Sprinkle flaky sea salt on top if desired to enhance the sweet and salty balance. Enjoy your perfect chewy butterscotch chocolate chip cookies!
Notes
- For best texture, do not overmix the dough once the flour is added.
- Chilling the dough is essential to prevent spreading and develop flavor.
- Adjust baking time slightly depending on your oven’s heat and desired cookie softness.
- Use parchment paper or silicone baking mats to avoid sticking and promote even baking.
- Sprinkling flaky sea salt is optional but recommended for a balanced sweet and salty taste.
