Instructions
Step 1
In a large mixing bowl, whisk together melted butter, brown sugar, and white sugar until smooth. Make sure there are no lumps left.
Then, add the large egg, egg yolk, and vanilla extract. Continue mixing until the mixture is creamy.
Step 2
In another bowl, combine all-purpose flour, cornstarch, baking soda, and salt.
Mix everything well to ensure it’s evenly distributed.
Step 3
Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix as this can affect the texture of your cookies.
Step 4
Gently stir in semisweet chocolate chips until evenly incorporated throughout the dough.
Step 5
Cover the dough with plastic wrap and chill in the refrigerator for 30 minutes. This step is important for achieving the perfect chewy texture.
Step 6
While the dough is chilling, preheat your oven to 350°F (177°C). Line a baking tray with parchment paper for easy cookie removal later on.
Step 7
Once chilled, scoop about 1 ½ tablespoons of dough and place them on the prepared baking tray, ensuring they are about 2 inches apart to allow for spreading.
Step 8
Bake in the preheated oven for 11 minutes. The cookies should look slightly soft in the center; they will continue to bake on the tray once removed from the oven.
Step 9
While the cookies are still warm, gently press some extra chocolate chips on top and sprinkle with flaky sea salt for a delightful finish.
Step 10
Allow the cookies to cool on the baking tray for a few minutes before transferring them to a wire rack. Enjoy the softest and chewiest cookies ever!
Servings
Equipment
Having a variety of sizes helps accommodate different mixing tasks. Lightweight and sturdy bowls will make your mixing easier.
A good whisk will help ensure that your butter and sugars blend seamlessly, providing that creamy texture we all love.



Use a flat, sturdy baking sheet lined with parchment paper for consistent baking. This prevents sticking and makes cleanup a breeze!
A cooling rack is essential for letting your cookies crisp up perfectly after baking, so don’t skip this step!



Variations
Faq
- Can I use margarine instead of butter?
Yes, margarine can be used, but your cookies might turn out a bit different in flavor and texture.
- Why do I need to chill the dough?
Chilling the dough helps prevent spreading during baking, resulting in thicker, chewier cookies.
- Can I double the recipe?
Absolutely! Just make sure you have enough space on your baking sheets and allow them enough time to bake through.
- What's the best way to store leftover cookies?
Store them in an airtight container at room temperature to keep them fresh. You can also freeze them for longer storage!
- How can I make my cookies even chewier?
Try adding a bit more brown sugar or reducing the baking time slightly for a softer center.
- If I want to add nuts, when should I mix them in?
Add the nuts when you stir in the chocolate chips. This will give your cookies that added crunch.
