Thin and Chewy Chocolate Chip Cookie Recipe

Please share this post with your friends 🤗

These cookies strike the rare balance between thin edges and a tender, chewy center. They’re the kind of cookie you can bake in a hurry and still feel proud of—crispy at the perimeter, soft where your teeth meet chocolate. No complicated techniques, just reliable steps and a dough that benefits from a short chill.

I test recipes like this a lot, and what matters most is timing, temperature, and respecting a few simple ingredient roles. Melted butter gives these cookies their thin profile, while the mix of sugars and a touch of cornstarch keeps them chewy. A little milk and two eggs create lift without puffy domes.

Read on for an ingredient-by-ingredient breakdown, clear step-by-step instructions, and practical tips so your batch comes out the same way every time—thin, chewy, and dotted with melty chocolate.

Ingredient Breakdown

• 1½ cups light brown sugar, packed — adds moisture and chew; brown sugar’s molasses keeps cookies soft and flavorful.
• ½ cup granulated sugar — helps spread and creates crisp edges when combined with melted butter.
• 2 sticks (1 cup) butter, melted and slightly cooled — melted butter encourages a thinner cookie with crisp edges; cool slightly so it doesn’t scramble the eggs.
• 2 large eggs, room temperature — provide structure and lift; room temperature eggs incorporate more evenly.
• 2 tablespoons milk — adds a touch of hydration so the dough isn’t dry; helps with spread and texture.
• 2 teaspoons vanilla extract — flavor backbone; don’t skip it for depth.
• 3 cups all-purpose flour — the main structure; measure properly (fluff, spoon, level) to avoid a dry, dense cookie.
• Pinch of salt — balances sweetness; essential for flavor clarity.
• ¾ teaspoon baking soda — contributes to spread and slight lift; helps browning.
• ½ teaspoon baking powder — adds a bit of lift and tenderness without puffing the cookie too much.
• 1 tablespoon cornstarch — a cheat for chewiness and a tender crumb; helps maintain a soft center.
• 1 cup semi-sweet chocolate chips — classic pockets of chocolate; choose quality chips for best flavor.
• 1 milk chocolate bar, roughly chopped — gives uneven, melty pockets and attractive tops when pressed into dough before baking.

Build Thin and Chewy Chocolate Chip Cookie Recipe Step by Step

1. Preheat and prepare: Line your baking sheets with parchment paper and set the oven to 350°F (175°C). This temperature encourages even browning and the right amount of spread for thin cookies.
2. Combine wet sugars and butter: In a large bowl, whisk the melted, slightly cooled butter with both the packed light brown sugar and the granulated sugar until smooth and homogenous. Scrape the sides as needed so everything is incorporated.
3. Add eggs and flavor: Add the eggs one at a time, whisking well after each addition so the mixture becomes cohesive. Stir in the 2 tablespoons milk and 2 teaspoons vanilla extract; whisk until the mixture looks smooth and slightly lighter in color.
4. Mix dry ingredients: In a separate bowl, whisk together 3 cups all-purpose flour, a pinch of salt, ¾ teaspoon baking soda, ½ teaspoon baking powder, and 1 tablespoon cornstarch. Whisking the dry ingredients ensures the leaveners are evenly distributed.
5. Combine wet and dry: Gradually add the dry ingredients to the wet mixture, stirring with a spatula or wooden spoon just until there are no streaks of flour. Avoid overmixing—stop as soon as the dough comes together.
6. Fold in chocolate: Fold in 1 cup semi-sweet chocolate chips and the roughly chopped pieces from 1 milk chocolate bar. Reserve a handful of chopped chocolate to press on top of each dough ball before baking for a glossy, melty finish.
7. Chill the dough: Cover the dough and chill for at least 30 minutes, or ideally overnight. Chilling hydrates the flour, firms the fat, and concentrates flavor—this step helps control spread so the cookies stay thin but chewy.
8. Portion dough: Using a 3-tablespoon scoop, portion chilled dough onto the prepared parchment-lined baking sheets, leaving ample space between each cookie for spreading (about 2–3 inches).
9. Top with chocolate: Press a few reserved chopped chocolate pieces onto the tops of each dough ball; this makes the cookies look bakery-fresh and gives melty pockets of chocolate.
10. Bake: Bake in the preheated 350°F (175°C) oven for 7–9 minutes. Watch for the edges to be lightly golden while the centers still look slightly underbaked—this ensures a chewy center once they cool.
11. Cool: Let the cookies cool on the baking sheet for 5 minutes so they set, then transfer to a wire rack to cool completely. They will firm up but remain tender inside.

Why It Deserves a Spot

These cookies are reliable and unfussy. Melted butter creates a thin profile without sacrificing chew, and the combo of brown and granulated sugar balances chewiness and crispness. The cornstarch and the small amount of milk are quiet but important helpers—cornstarch softens while milk keeps dough pliable. You get that pleasing contrast of a lacy edge and a soft, chocolate-studded interior every time.

They also photograph well and travel nicely—cool completely before stacking, and they hold their texture for a day or two at room temperature in an airtight container.

Allergy-Friendly Substitutes

• Dairy-free butter substitute: Use a vegan stick margarine melted and cooled in place of the butter; expect slightly different spread and flavor.
• Egg replacer: For egg allergy, use a commercial egg replacer following package ratio for two eggs, or 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit 5 minutes).
• Milk substitute: Any plant milk (soy, oat, almond) can replace the 2 tablespoons of milk.
• Chocolate: Use dairy-free chocolate chips or chopped dairy-free bars to keep it allergy-friendly.

Equipment Breakdown

• Baking sheets: Two rimless or rimmed sheets for even airflow; rotate halfway if your oven heats unevenly.
• Parchment paper: Prevents sticking and promotes even bottoms without extra grease.
• Mixing bowls: One large for wet mixture and one medium for dry ingredients.
• Whisk and spatula: Whisk for wet and dry mixing; spatula for folding keeps the dough tender.
• 3-tablespoon cookie scoop: For uniform cookies so baking times are consistent.
• Wire rack: For cooling so bottoms don’t become soggy.

Easy-to-Miss Gotchas

• Butter temperature: If the butter is too hot you’ll cook the eggs; let it cool slightly after melting.
• Measuring flour: Scooping flour directly can pack it and yield dry, cakey cookies. Fluff the flour, spoon into the cup, then level.
• Chilling is important: Skipping the chill risks excessive spread and thinner, flatter cookies that lack chew.
• Baking time window: 7–9 minutes is short—overbaking by a minute or two will dry them out. Remove when centers look slightly underbaked.
• Cookie spacing: Give room for spread. Crowding the pan leads to merged cookies and uneven baking.

Adaptations for Special Diets

Vegan

• Swap butter for vegan stick margarine, replace eggs with two flax eggs (2 tbsp ground flax + 6 tbsp water), and use plant milk plus dairy-free chocolate chips.

Lower-sugar

• Reduce granulated sugar slightly (try ¼ cup instead of ½) but understand texture and spread will change; brown sugar contributes chew so keep most of it.

Gluten-free

• Use a 1:1 gluten-free all-purpose flour blend with xanthan gum included. Watch hydration; you may need to chill longer for structure.

Notes on Ingredients

• Brown sugar: Using light brown sugar is called for—its molasses content supports chewiness without overpowering flavor.
• Cornstarch: Just 1 tablespoon helps maintain a tender center; don’t omit if you want that soft chew.
• Baking soda + baking powder: Both are used to control spread and texture. Baking soda helps browning and thinness; baking powder adds gentle lift.
• Chocolate mix: The combination of chips and chopped bar gives consistent pockets (chips) and gooey, uneven melt (chopped bar).

Freezer-Friendly Notes

• Freeze dough balls: Scoop dough onto a tray, freeze until solid, then transfer to a zip-top bag. Bake from frozen—add 1–2 minutes to baking time.
• Freeze baked cookies: Cool completely, then flash-freeze on a tray and store in airtight containers. Thaw at room temperature for best texture.

Your Questions, Answered

• Q: Can I skip chilling? A: You can, but expect more spread and thinner, crisper cookies. Chilling improves texture and flavor.
• Q: My cookies spread too much—why? A: Likely too-warm dough, too-warm butter, too much sugar, or not enough chill time. Also check your oven temperature with a thermometer.
• Q: Can I make them thicker? A: Chill longer and scoop larger dough mounds, or substitute a small portion of flour with a tablespoon more to slightly firm the dough.
• Q: Why both baking soda and powder? A: They balance spread and lift—soda encourages thinness and browning, powder gives gentle height so the cookie isn’t flat as a cracker.

Time to Try It

Preheat your oven, pull out the butter and eggs to warm slightly, and give the dough the chill it deserves. Follow the steps exactly for the first batch; once you know how your oven and ingredients behave, tweak minor things like bake time or chill length to suit your preference.

Enjoy the ritual of pressing extra chocolate on top before they go into the oven—it’s a small step that makes them inviting and lets you taste molten chocolate in every bite. Happy baking.
