These Two-Chip Chocolate Chip Cookies take a classic American chocolate chip cookie and make it even better with two different kinds of chocolate in every bite. Semisweet chips bring deep chocolate flavor, while milk chocolate chips add creamy sweetness.
The cookies bake up with lightly crisp golden edges, thick chewy centers, and plenty of gooey chocolate pockets. Brown sugar keeps them soft and adds caramel notes, while a little cornstarch helps create that tender bakery-style center.
They're perfect for cookie trays, bake sales, parties, lunchboxes, holiday baking, or serving warm with a cold glass of milk.
Ingredients
For the Cookie Dough
- 2¾ cups (345g) all-purpose flour
- 1 tablespoon cornstarch
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ¾ teaspoon kosher salt
- 1 cup (226g) unsalted butter, softened
- 1 cup (200g) packed light brown sugar
- ½ cup (100g) granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons pure vanilla extract
- 1¼ cups semisweet chocolate chips
- 1¼ cups milk chocolate chips
For Finishing
- Extra semisweet chocolate chips
- Extra milk chocolate chips
- Flaky sea salt, optional
How to Make Two-Chip Chocolate Chip Cookies
Step 1 – Combine the Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Cornstarch
- Baking soda
- Baking powder
- Salt
Set aside.
Step 2 – Cream the Butter & Sugars
Place the softened butter, brown sugar, and granulated sugar in a large mixing bowl.
Beat for approximately 2–3 minutes, until creamy and slightly fluffy.
Scrape down the sides and bottom of the bowl.
Don't use melted butter for this version. Softened butter helps the cookies stay thicker.
Step 3 – Add the Eggs
Beat in the eggs one at a time, mixing well after each addition.
Add the vanilla and mix until incorporated.
Step 4 – Add the Dry Ingredients
Add the dry ingredients to the butter mixture.
Mix on low speed just until the dough comes together.
Stop as soon as you no longer see obvious streaks of flour.
Don't overmix.
Add Both Chocolates
Step 5 – Fold in the Chips
Add the semisweet and milk chocolate chips.
Fold them through the dough with a rubber spatula.
The dough should be thick and generously packed with chocolate.
Reserve a handful of each type of chip for decorating the cookies before or immediately after baking.
Chill the Dough
Step 6 – Refrigerate
Cover the cookie dough and refrigerate for at least 30–60 minutes.
For an even deeper caramel flavor and thicker cookie, chill it for several hours or overnight.
Chilling allows the flour to hydrate and prevents the cookies from spreading excessively.
Shape the Cookies
Step 7 – Prepare for Baking
Preheat the oven to 350°F (175°C).
Line large baking sheets with parchment paper.
Scoop approximately 2½–3 tablespoons of dough for each cookie.
Roll very lightly into balls, then shape them slightly taller rather than perfectly round and flat.
Arrange them several inches apart on the baking sheet.
Step 8 – Add Extra Chocolate
Press several semisweet and milk chocolate chips into the tops of the dough balls.
This creates those visible pools of chocolate that make bakery-style cookies look especially tempting.
Bake
Bake at 350°F (175°C) for approximately 10–13 minutes.
The cookies are ready when:
- The edges are lightly golden
- The tops look mostly set
- The centers still appear slightly soft and underdone
Don't wait for the centers to look completely baked.
They'll continue cooking from the heat of the baking sheet.
Let Them Set
Leave the cookies on the hot baking sheet for approximately 5–10 minutes.
If desired, immediately press a few additional chocolate chips into the warm tops.
Sprinkle lightly with flaky sea salt.
Transfer to a wire rack to finish cooling.
For maximum gooeyness, serve while they're still slightly warm.
Chef's Tips for the Best Two-Chip Cookies
- Use softened, not melted, butter for thick cookies.
- Measure flour carefully; too much produces dry, cakey cookies.
- Brown sugar is important for moisture and chewiness.
- Cornstarch helps keep the centers tender.
- Use room-temperature eggs for easier mixing.
- Don't overmix after adding flour.
- Use both semisweet and milk chocolate for better flavor contrast.
- Chill the dough before baking.
- Make the dough balls slightly tall for thicker cookies.
- Leave plenty of space between cookies.
- Don't overbake.
- Let the cookies finish setting on the baking sheet.
- Add extra chocolate to the tops for a bakery-style appearance.
- A tiny amount of flaky salt helps balance the sweetness.
The Secret to Thick, Chewy Centers
The combination of brown sugar, cornstarch, chilled dough, and slight underbaking creates the texture.
Brown sugar holds moisture and adds chewiness, while cornstarch softens the crumb.
Chilling is equally important. Warm dough spreads before its structure has time to set in the oven. Cold dough melts more slowly, giving you thicker cookies.
Finally, remove the cookies while their centers still look slightly soft.
Those centers continue setting as the cookies cool, giving you that perfect chewy texture instead of a dry, crunchy cookie.
Why Use Two Kinds of Chocolate?
Using two chips isn't just about adding more chocolate.
Semisweet chocolate has a deeper, slightly bitter cocoa flavor that keeps the cookies balanced.
Milk chocolate is sweeter, softer, and creamier.
When they're combined, every bite tastes a little different depending on which chocolate pockets you hit.
For even more texture, replace half of either type of chip with roughly chopped chocolate bars.
Delicious Variations
Dark & White Chocolate
Replace the milk chocolate chips with white chocolate chips and use dark chocolate instead of semisweet.
Chocolate & Butterscotch
Use semisweet chocolate chips plus butterscotch chips for a buttery caramel flavor.
Chocolate Peanut Butter
Replace the milk chocolate chips with peanut butter chips.
Chocolate Toffee
Replace ½ cup of the milk chocolate chips with crunchy toffee bits.
Chocolate Pecan
Add ¾ cup toasted chopped pecans.
Triple-Chip Cookies
Add ¾ cup each semisweet, milk, and white chocolate chips.
Salted Caramel Two-Chip Cookies
Add caramel bits to the dough and finish the warm cookies with flaky sea salt.
Make Them Extra Bakery-Style
For oversized bakery cookies, portion approximately ¼ cup dough per cookie.
Shape the dough into tall mounds and chill thoroughly.
Bake at 350°F (175°C), adding several minutes as necessary.
The edges should be golden while the centers remain soft.
Immediately after baking, press extra semisweet and milk chocolate pieces into the tops.
This gives the cookies a thick, chocolate-packed appearance without overbaking them.
Make-Ahead Tips
The cookie dough can be refrigerated for approximately 2–3 days before baking.
You can also portion the dough into individual balls before refrigerating.
For longer storage, freeze the unbaked dough balls on a baking sheet until firm, then transfer them to a freezer-safe bag.
Bake directly from frozen, adding approximately 1–3 minutes to the normal baking time.
Storage
Room Temperature
Store completely cooled cookies in an airtight container for approximately 4–5 days.
A small piece of bread placed in the container can help the cookies stay soft.
Freezer
Baked cookies can be frozen for up to 2–3 months.
Unbaked cookie dough balls can also be frozen for approximately 3 months.
How to Reheat
For that fresh-from-the-oven texture, microwave one cookie for approximately 8–10 seconds.
The center will soften and the two types of chocolate will become gooey again.
Don't microwave for too long or the cookie can become tough after cooling.
Notes
- This recipe makes approximately 18–24 large cookies, depending on portion size.
- Use good-quality chocolate chips because chocolate is the dominant flavor.
- If you prefer less-sweet cookies, use dark chocolate chips instead of milk chocolate.
- For attractive bakery-style cookies, reserve plenty of both chips and press them into the tops while the cookies are still warm.
- The cookies should look slightly underdone in the center when they leave the oven. This is intentional.
- For the best flavor, chill the dough for at least an hour; overnight chilling produces an even deeper caramelized flavor.
- Two-Chip Chocolate Chip Cookies are perfect for after-school treats, bake sales, holiday cookie boxes, birthday parties, potlucks, late-night desserts, or simply eating warm from the oven with a glass of cold milk.
