Prep Time: 15 minutes | Chill Time: 2 hours (Recommended) | Bake Time: 10 minutes | Yields: 24 Cookies
We have all been there: You bake a batch of cookies, and they come out flat, greasy, or rock-hard the next day. Not this time. This is the Holy Grail of chocolate chip cookie recipes.
These cookies feature golden, slightly crisp edges and a center that stays impossibly soft and chewy for days. The secret? A higher ratio of brown sugar for moisture, an extra egg yolk for richness, and a touch of cornstarch to keep them pillow-soft.
Whether you are a dunker (milk lovers, unite!) or a dough-eater, this recipe delivers that nostalgic, bakery-quality comfort you crave.

Ingredients You’ll Need (The Science of Softness)
-
Butter: 3/4 cup (1.5 sticks) Unsalted Butter, melted and slightly cooled. Melted butter = chewier cookie. Softened butter = cakier cookie.
-
Sugar:
-
1 cup Packed Light Brown Sugar (The molasses keeps them moist).
-
1/2 cup Granulated White Sugar (For crispy edges).
-
-
Eggs: 1 large Egg + 1 large Egg Yolk. The extra yolk adds fat and richness, creating that fudgy texture.
-
Vanilla: 2 teaspoons Pure Vanilla Extract.
-
Flour: 2 ¼ cups All-Purpose Flour. (Spoon and level, don’t scoop!).
-
Cornstarch: 1 teaspoon. The secret ingredient for softness.
-
Leavening: 1 teaspoon Baking Soda.
-
Salt: 1/2 teaspoon.
-
Chocolate: 1 ½ cups Semi-Sweet Chocolate Chips (or chunks for puddles of chocolate).
How to Make Soft Chocolate Chip Cookies (Step-By-Step)
Step 1: The Wet Mix
In a large bowl, pour in the melted butter, brown sugar, and white sugar. Whisk vigorously for 2 minutes.
-
Why? Whisking dissolves some of the sugar, which creates that shiny, crackly top we all love.
-
Add the egg, egg yolk, and vanilla. Whisk until smooth.
Step 2: The Dry Mix
Pour the flour, cornstarch, baking soda, and salt right on top of the wet ingredients. Switch to a rubber spatula or wooden spoon. Mix just until no flour streaks remain.
-
Pro Tip: Do not overmix! Overmixing develops gluten, which makes cookies tough instead of tender.
Step 3: The Chocolate Fold
Fold in the chocolate chips.
-
Chef’s Trick: Reserve about 1/4 cup of chips to press onto the tops of the dough balls later. This makes them look professionally made.
Step 4: The Chill (Don’t Skip This!)
Cover the bowl and chill in the fridge for at least 2 hours (or up to 3 days).
-
The Science: Chilling solidifies the butter so the cookies don’t spread too thin. It also allows the flour to hydrate, leading to a deeper, caramel-like flavor.
Step 5: Bake
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Scoop tall mounds of dough (about 2 tbsp each). Roll them into balls and place them 2 inches apart. Press the reserved chocolate chips on top.
Bake for 10-12 minutes.
-
The Sweet Spot: Take them out when the edges are barely golden but the center still looks undercooked and soft. They will set as they cool.
Step 6: The Cool
Let them cool on the baking sheet for 10 minutes before moving to a wire rack. This “carryover cooking” finishes the center perfectly.
Expert Tips for Perfection
-
The “Pan Bang”: If your cookies are puffy in the middle while baking, lift the baking sheet 3 inches and drop it flat on the oven rack. This deflates the center and creates beautiful ripples.
-
Measure Flour Correctly: Don’t scoop your cup into the flour bag! This packs it down, and you’ll end up with dry cookies. Spoon the flour into the cup and level it off with a knife.
-
Use Room Temp Eggs: Cold eggs mixed with warm butter can curdle the batter. Sit your eggs in a bowl of warm water for 5 minutes before using.
Storage and Freshness Hacks
How to Keep Them Soft for Days
Place a slice of white bread in the airtight container with your baked cookies.
-
Why? The cookies are hygroscopic (they attract moisture). They will steal the moisture from the bread, keeping them soft while the bread turns hard as a rock!
Freezing Dough
Roll the dough into balls and freeze them on a tray for 1 hour. Transfer to a Ziploc bag.
-
To Bake: Bake straight from frozen! Just add 1-2 extra minutes to the bake time.
Recipe Variations
-
Double Chocolate: Swap 1/4 cup of flour for cocoa powder.
-
Salted Caramel: Stuff a soft caramel candy inside the dough ball and sprinkle sea salt on top after baking.
-
The “Kitchen Sink”: Add crushed pretzels, potato chips, and white chocolate chips for a salty-sweet crunch.
Frequently Asked Questions (FAQ)
Q: Why are my cookies flat?
A: You likely melted the butter too much (it should not be hot) or didn’t chill the dough long enough. Also, check that your baking soda isn’t expired!
Q: Can I skip the cornstarch?
A: You can, but they won’t be as soft. The cornstarch tenderizes the dough proteins.
Q: Why use melted butter instead of creamed?
A: Creaming butter and sugar adds air (aeration) for a cakey texture. Melted butter creates a denser, chewier, fudgier texture.
