There is a reason chocolate chip cookies never go out of style. A great one is crisp at the edges, soft in the middle and loaded with melted chocolate. These sea salt chocolate chip cookies take that classic and add one small detail that changes everything: flaky salt on top.
The salt sharpens the chocolate, cuts through the sweetness and gives each bite a tiny crunch. It is the difference between a cookie that is nice and a cookie that people ask you to make again.
I baked countless trays to get this version just right. The dough is easy, the chill time does the heavy lifting, and the instructions below will help you get thick, bakery-style cookies that hold their shape.

The Secrets Behind a Perfect Cookie
Three details separate good cookies from great ones. First is the balance of sugars. More brown sugar than white gives a chewy, moist center with caramel notes, while a little white sugar helps the edges crisp. Second is the extra egg yolk, which adds richness and chew.
Third, and most important, is resting the dough. As cold dough sits, the flour absorbs moisture and the flavors deepen. The cookies spread less in the oven, so they bake up thick instead of flat and greasy. Even 60 minutes in the refrigerator makes a visible difference.
If you love brown butter flavor, my brown butter chocolate chip cookies take a nutty, toffee-like direction, while this recipe stays classic and buttery.
Finally, bake with intention. Underbaking by a minute is better than overbaking by one. Cookies look done when the edges are set and golden, while the center still seems a bit puffy and pale. They finish setting on the hot pan, and that gentle carryover cooking is what keeps the middle soft and chewy.
Ingredients and Why They Matter
- Butter: softened but still cool, about 65F (18C). It should dent when pressed but not look greasy.
- Brown and granulated sugar: brown for chew, white for crisp edges.
- Eggs and one extra yolk: room temperature for even mixing.
- Vanilla extract: real vanilla, a generous amount.
- All purpose flour: spooned and leveled, never scooped.
- Baking soda and cornstarch: soda helps browning, cornstarch keeps the center tender.
- Chocolate chunks or chopped bars: they melt into layered pools, unlike chips.
- Flaky sea salt: such as large flakes, for the finishing touch.
A word on the extra yolk and the cornstarch. The yolk contributes fat and emulsifiers that make the cookie chewy and rich, and the cornstarch softens the crumb so the center stays tender even after the cookies cool. Both are small additions, but together they are why these cookies stay soft for days.
Mixing the Dough Step by Step
- Whisk the flour, cornstarch, baking soda and fine salt in a bowl.
- Beat the butter with both sugars on medium speed for 2 minutes until pale and fluffy.
- Beat in the eggs and the extra yolk one at a time, then the vanilla.
- Add the dry ingredients on low and mix just until a few streaks of flour remain.
- Fold in the chocolate by hand, saving a handful for the tops.
- Cover and chill for at least 1 hour, or up to 48 hours.
- Heat the oven to 350F (175C) and line two baking sheets with parchment.
- Scoop 3 tablespoon mounds of dough, about 2 inches apart. Press the reserved chocolate on top.
- Bake 11 to 13 minutes until the edges are golden and the centers look slightly underdone.

If the dough feels sticky after mixing, that is normal. Chilling firms it up. If it feels dry and crumbly, a teaspoon of milk will bring it together. Avoid adding extra flour, as that will make the finished cookies dry.
The Finishing Touch: Flaky Salt
Sprinkle a few flakes on each cookie as soon as the tray comes out of the oven. The surface is still soft, so the salt sticks, and the residual heat softens its edges just slightly. Do it earlier and the salt dissolves and disappears into the dough.
Use flaky salt for the finishing step, not fine table salt. The large crystals add crunch and a clean salty pop. If your flakes are very large, crush them lightly between your fingers. A pinch per cookie is plenty, and too much can overpower the chocolate.
Choosing the Best Chocolate
Chocolate is the star, so it deserves a little thought. Chopped bars of semisweet or bittersweet chocolate between 55 and 70 percent cacao create layers and pools that stay glossy after baking. Chips hold their shape because they contain stabilizers, which is nice for neat cookies but less dramatic.
I like a mix. Roughly three quarters chopped bar and one quarter chips gives both fine shards that melt into the dough and big pieces that stay molten. Chopping also makes tiny dust that colors the dough with chocolate streaks, which tastes wonderful.
If you prefer a sweeter cookie, use milk chocolate for half of the mix. If you love bitter notes, add a spoonful of espresso powder to the dough. Either way, keep the total at about 2 cups so the dough still holds together.
A Simple Baking Day Plan
Cookies feel easy when the schedule is clear. Mix the dough in the morning or the night before, and keep it in the fridge until you are ready. Cold dough scoops cleanly and gives the best shape.
About 15 minutes before baking, heat the oven and line the pans. Scoop all of the dough while you wait, placing extra balls on a plate in the fridge. Bake one pan at a time, and cool the pan under cold water between batches so the next scoops do not melt before they hit the oven.
While the first tray cools, mix a glass of milk or brew coffee. A warm cookie, still slightly gooey in the middle, is the whole reason you went to the trouble.
Tips for Thick, Chewy Cookies
- Do not overbeat the butter and sugar. Two minutes is enough, and more air leads to flat cookies.
- Use cool room-temperature butter. Warm or melted butter makes dough that spreads.
- Scoop the dough tall rather than flattening it.
- Bake one tray at a time on the center rack for even heat.
- Pull the cookies when the middles still look soft. They finish on the hot pan.
- Cool on the pan for 5 minutes, then move to a wire rack.
Using a scale and a scoop
A large cookie scoop is the quickest way to get uniform cookies. Uniform size means uniform baking, so every cookie finishes at the same time. A 3 tablespoon scoop gives 20 large cookies, and a 1.5 tablespoon scoop gives about 40 smaller ones, which take 9 to 10 minutes.
Troubleshooting Cookie Problems
| Problem | Fix |
|---|---|
| Cookies spread too much | Chill longer, use cooler butter, and bake on cool pans. |
| Cookies are cakey | Too much flour or too much mixing. Measure by weight. |
| Bottoms are dark | Use light-colored pans and parchment, and move the rack up. |
| Dry, crumbly dough | Too much flour. Add a teaspoon of milk to bring it together. |
| Salt is gone | Add it right after baking, not before. |
Oven temperature matters more than people realize. An oven that is 25 degrees too hot makes cookies that brown and set before the center cooks, while one that is too cool makes them spread. A simple oven thermometer lets you adjust and gives consistent results.
Mix-Ins and Variations
- Toasted nuts: add 3/4 cup chopped pecans or walnuts.
- Dark chocolate: use 70 percent bars for a bolder, less sweet cookie.
- Espresso: add a teaspoon of instant espresso powder to the dry ingredients.
- Oatmeal: replace 3/4 cup flour with quick oats, or see my soft oatmeal cookies.
- Cinnamon sugar: roll half the dough in sugar for a snickerdoodle twist like my snickerdoodle cookies.
For gifts, bake a double batch and layer cooled cookies in a tin with parchment between each layer. They stay soft for days when stored properly, and they look beautiful with a ribbon.
Storage, Freezing and Food Safety
Store cooled cookies in an airtight container at room temperature for up to 4 days. Add a slice of bread to keep them soft. For longer storage, freeze baked cookies for up to 3 months and warm them for a few seconds in the microwave before serving.
The best make-ahead trick is freezing the dough. Scoop it into balls, freeze on a tray, then bag them. Bake straight from frozen at 350F (175C), adding 2 to 3 minutes. You will always be 15 minutes away from warm cookies.
Because the dough contains raw eggs and flour, do not eat it raw. Bake until the edges are set. The USDA gives general tips on leftovers and food safety that apply to baked goods with dairy and eggs.
Frequently Asked Questions
Do I really have to chill the dough?
For the best result, yes. Chilling prevents spreading and builds flavor. If you are in a hurry, chill at least 30 minutes and expect slightly flatter cookies.
Can I use chocolate chips instead of chunks?
Yes. Semisweet chips work fine, though chopped chocolate bars melt into prettier layers and pools.
Why did my cookies turn out flat?
Common causes are warm butter, a warm baking sheet, too little flour or old baking soda. Chill the dough and bake on cool pans.
Can I freeze cookie dough?
Yes. Freeze scooped dough balls for up to 3 months and bake from frozen, adding a couple of minutes.
What kind of salt should I use on top?
Use flaky sea salt. Fine table salt dissolves and tastes harsh, while flaky salt provides crunch and a mild finish.
