Every family has a cookie benchmark. Ours was my grandmother’s tin, the one with the dented lid that lived on top of her fridge and was never, ever empty when grandchildren visited. Her cookies bent before they broke. The edges had the faintest crisp, the middles stayed soft for days, and the chocolate pooled instead of sitting in tidy little chips. It took me years of flat, cakey, disappointing batches to figure out what she was doing. This recipe is the result, and it has not failed me yet.
The Three Things That Decide Chewiness
Forget secret ingredients. Chewy cookies come down to three plain decisions, and once you understand them you can fix any cookie recipe you own.
One: melted butter, not creamed. Creaming butter with sugar whips in air, and air makes cookies rise and turn cakey. Melted butter coats the flour differently and gives you that dense, bendy chew. It also means no waiting for butter to soften and no mixer required.
Two: more brown sugar than white. Brown sugar carries molasses, and molasses holds moisture. A two to one ratio of brown to white sugar keeps the centers soft well into day three. Dark brown sugar gives a deeper, almost toffee flavor; light brown works if that is what you have.
Three: pull them out looking underdone. This is the one people resist. The centers should look pale, puffy, and slightly raw when the timer goes off. Carryover heat on the hot pan finishes them gently. Bake until they look properly done and they will be hard by dinner.
Ingredients
Makes 24 cookies.
- 3/4 cup (170 g) unsalted butter, melted and cooled for 10 minutes
- 1 cup (200 g) packed dark brown sugar
- 1/2 cup (100 g) granulated sugar
- 1 large egg plus 1 egg yolk, at room temperature
- 2 tsp pure vanilla extract
- 2 1/4 cups (280 g) all purpose flour, spooned and leveled
- 1 tsp cornstarch
- 1 tsp baking soda
- 3/4 tsp fine sea salt
- 1 1/2 cups (255 g) semisweet chocolate chips, plus a few extra for the tops
- Flaky sea salt, for sprinkling (optional but lovely)
Two ingredient notes. The extra yolk is not a typo: yolks add fat and richness without the water that egg whites bring, so the cookies stay tender instead of puffing up. And the cornstarch, just a teaspoon, softens the crumb in a way people notice but cannot name. My grandmother would have called it the tenderizer.
Step by Step Instructions
1. Melt and cool the butter
Melt the butter in a large microwave safe bowl or a small saucepan. Let it sit for 10 minutes. It should feel warm, not hot. Butter that is too hot will melt the sugars into syrup and can scramble the egg, and both mistakes spread your cookies thin.
2. Whisk in the sugars and eggs
Whisk the brown and granulated sugars into the butter for about 1 minute, until the mixture looks glossy and smooth. Add the egg, the yolk, and the vanilla, and whisk again until it thickens slightly and falls off the whisk in ribbons. This step dissolves the sugar, which is part of where the shiny, crackly top comes from.
3. Fold in the dry ingredients
Sprinkle the flour, cornstarch, baking soda, and salt over the bowl. Fold with a spatula until you see the last dry streaks disappear, then fold in the chocolate chips. Stop the moment it comes together. Overmixing builds gluten, and gluten is the enemy of a tender cookie.
4. Chill the dough
Cover the bowl and refrigerate for at least 30 minutes, and up to 72 hours. I know. Waiting is the hardest step in the recipe. But cold dough spreads slowly in the oven, so the cookies bake up thick with chewy middles instead of thin and lacy. The flavor deepens overnight too, in a way that genuinely surprises people.
5. Scoop and bake
Heat the oven to 350°F (175°C) and line two baking sheets with parchment. Scoop the dough into balls of about 3 tablespoons each (roughly 55 g). A cookie scoop makes this fast and keeps the sizes even. Set 8 or 9 balls on each sheet, at least 2 inches apart, and press a few extra chips onto the tops.
Bake for 10 to 12 minutes, rotating the pan halfway through, until the edges look set and faintly golden while the centers still look soft and slightly pale. Trust the edges, not the middle.
6. Rest on the pan
Leave the cookies on the hot baking sheet for 10 full minutes. They finish setting during this rest, and if you try to move them sooner they will fold and tear. Sprinkle with flaky salt while they sit, then move them to a wire rack.
Storage and Freezing
Stored in an airtight container at room temperature, these stay soft for about 4 days. Here is the old trick that actually works: tuck half a slice of sandwich bread into the container. The cookies absorb moisture from the bread and stay chewy, while the bread goes stale instead of them. Baked cookies freeze well for up to 3 months.
For fresh cookies on demand, freeze the dough instead. Scoop the balls onto a tray, freeze until solid (about 1 hour), then bag them for up to 3 months. Bake straight from frozen at the same temperature, adding 1 to 2 minutes. A bag of these in the freezer has saved more of my evenings than I can count.
Ways to Make Them Yours
Brown butter version: cook the melted butter in a light colored pan for 3 to 4 extra minutes, swirling, until the foam subsides and the milk solids turn amber and smell like hazelnuts. Cool it the same 10 minutes. The flavor goes deep and nutty, and it is the single easiest upgrade in this whole recipe.
Double chocolate: replace 1/4 cup of the flour with unsweetened cocoa powder and use dark chocolate chips. The result eats like a brownie in cookie form.
Oatmeal twist: swap 3/4 cup of the flour for old fashioned rolled oats. Chewier still, with a heartier bite that holds up well in lunchboxes.
Peanut butter cup: fold in 1 cup of chopped peanut butter cups instead of half the chips. Salty, sweet, and dangerously good warm.
Troubleshooting
My cookies spread into one giant cookie. The butter was too hot, the dough skipped its chill, or the flour was short. Measure flour by weight if you can, and never put dough on a warm baking sheet.
My cookies came out puffy and cakey. Usually too much flour, or the dough was mixed hard after the flour went in. Spoon and level the flour rather than scooping from the bag, which can pack in an extra quarter cup.
My cookies were soft today and hard tomorrow. They were overbaked, even if they did not look it. Next batch, take them out a full minute earlier. The bread slice trick above can rescue a slightly overbaked batch.
My cookies look lopsided. Scoop even balls, and try the round cookie trick: right when the tray comes out, place a large round cookie cutter or glass over each cookie and swirl it gently for a few seconds. It nudges them into perfect circles while they are still soft.

Frequently Asked Questions
Do I really have to chill the dough?
For thick, chewy cookies, yes. Thirty minutes is the minimum that makes a real difference. If you are desperate, scoop the balls and freeze them for 15 minutes while the oven heats. It is not quite as good, but it is close.
Can I use salted butter?
You can. Drop the added salt in the dough to 1/4 tsp and skip the flaky salt on top. The cookies will still be delicious.
Why cornstarch? Can I leave it out?
Cornstarch keeps the crumb soft and tender for days instead of just hours. You can leave it out and the cookies will still work, they just will not stay soft as long.
Can I swap the chocolate?
Absolutely. Chopped chocolate bars melt into pools and shards, which many bakers prefer to chips. Bittersweet or dark chocolate balances the sweet dough nicely, and a handful of chopped walnuts or pecans folded in is never a bad idea.
How do I make a half batch?
Halve everything and use 1 whole egg instead of the egg plus yolk. You will get about 12 cookies, and the bake time stays the same.
Can I bake these in a convection oven?
Yes. Drop the temperature to 325°F (165°C) and start checking at 9 minutes. The fan firms up the edges faster, so the window between perfect and overbaked gets a little narrower.
Why are my cookie bottoms dark?
Dark, thin baking sheets absorb more heat and brown bottoms quickly. Use a light colored, heavy sheet, or stack two thin sheets together as insulation. A sheet of parchment between the dough and the pan also buys you a gentler bake.
