🥄 Ingredient Notes

Use Softened Butter for Thick, Bakery-Style Cookies

Softened butter is important for creating the rich, tender texture in these Crumbl Hazelnut Sea Salt Cookies. The butter should feel soft to the touch but not greasy or melted, which helps the dough stay thick and keeps the cookies from spreading too much in the oven.

Brown Sugar Adds Moisture and Chew

Brown sugar gives these cookies their soft, chewy texture and deeper caramel-like flavor. Since this recipe is meant to mimic a thick Crumbl-style cookie, the higher amount of brown sugar helps create a richer cookie base that pairs perfectly with the gooey hazelnut center.

Hazelnut Spread Creates the Signature Gooey Center

The frozen hazelnut spread is the star of this cookie recipe. Freezing it before stuffing the dough helps create that soft, molten middle while keeping the filling from leaking out too quickly during baking.

Cornstarch Helps Keep the Cookies Soft

A small amount of cornstarch helps give these cookies a softer, more tender crumb. It also supports that thick bakery-style texture, which is especially helpful when making large cookies with a stuffed center.

Flaky Sea Salt Balances the Sweetness

Flaky sea salt is the finishing touch that makes these Crumbl Hazelnut Sea Salt Cookies taste extra special. It balances the sweetness of the cookie and hazelnut filling while adding a light crunch and more gourmet flavor.

🍪 How to Make Crumbl Hazelnut Sea Salt Cookies

Freeze the Hazelnut Filling First

Start by lining a small plate or tray with parchment paper. Scoop the hazelnut spread into small 2-teaspoon portions and place them on the parchment. Freeze them until completely solid. This step is very important because it helps create that gooey center while keeping the filling from leaking too much during baking.

Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until smooth and fluffy. This usually takes about 2 to 3 minutes. Properly creaming the butter and sugars helps give these Crumbl Hazelnut Sea Salt Cookies their soft, thick bakery-style texture.

Mix in the Eggs and Vanilla

Add the eggs, egg yolk, and vanilla extract to the bowl and mix until fully combined. The extra egg yolk adds richness and helps create a soft, tender cookie with a chewy center.

Add the Dry Ingredients

Add the all-purpose flour, baking soda, salt, and cornstarch to the bowl. Mix just until a thick cookie dough forms. Be careful not to overmix, since overworking the dough can make the cookies tougher instead of soft and tender.

Stuff and Shape the Cookies

Divide the dough into large portions. Flatten each piece of dough slightly, place one frozen hazelnut filling portion in the center, and wrap the dough around it. Seal the edges completely, then shape each cookie into a tall mound instead of flattening it. This helps the cookies stay thick while baking.

Chill Before Baking

Place the shaped cookies in the refrigerator for 20 to 30 minutes. Chilling the dough helps prevent spreading and gives the cookies their signature Crumbl-style thickness.

Bake Until the Edges Are Set

Preheat your oven to 350°F and line a baking sheet with parchment paper. Bake the cookies for 12 to 14 minutes, or until the edges are set and the centers are still soft. The cookies will continue to firm up slightly as they cool on the pan.

Finish with Sea Salt and Drizzle

As soon as the cookies come out of the oven, sprinkle them with flaky sea salt. If you want the full bakery-style finish, add a light chocolate drizzle once the cookies have cooled slightly. This final touch makes the cookies look beautiful and adds even more rich hazelnut-chocolate flavor.

🍪 Pro Tips

Freeze the Filling Until Completely Solid

Freezing the hazelnut spread until fully solid makes these Crumbl Hazelnut Sea Salt Cookies much easier to assemble and helps keep the centers thick and gooey after baking. If the filling is too soft, it can leak out more easily while the cookies bake.

Keep the Dough Tall for a True Crumbl Look

Instead of flattening the cookie dough, shape each portion into a tall mound before baking. This simple step helps create the thick, bakery-style cookie shape that makes Crumbl cookies so recognizable.

Do Not Overbake the Cookies

For the best texture, remove the cookies from the oven when the edges are set but the centers still look soft. Slightly underbaking is the key to getting that soft, chewy middle and rich gooey center in these hazelnut sea salt cookies.

Seal the Dough Well Around the Filling

Make sure the cookie dough fully wraps around the frozen hazelnut center with no cracks or thin spots. This helps keep the filling inside the cookie and gives you a cleaner, more bakery-style result.

Add the Sea Salt Right After Baking

Sprinkle the flaky sea salt over the cookies while they are still warm so it sticks to the tops. This finishing touch balances the sweetness and makes the flavors taste even more rich and irresistible.

🍪 Variations

Add a Light Chocolate Drizzle

A light chocolate drizzle is one of the best ways to dress up these Crumbl Hazelnut Sea Salt Cookies without changing the flavor too much. It adds a pretty bakery-style finish and gives the cookies an extra touch of rich chocolate flavor that pairs perfectly with the gooey hazelnut center.

Make Them Extra Salty and Sweet

If you love a stronger sweet-and-salty contrast, add a little extra flaky sea salt on top after baking. This simple variation makes the hazelnut flavor pop even more and gives the cookies a more gourmet bakery-style feel.

Use Mini Stuffed Cookies Instead

You can turn this recipe into smaller stuffed cookies if you want a bite-sized version for parties, cookie trays, or holiday baking. Just use smaller portions of dough and a smaller amount of hazelnut filling, then reduce the baking time as needed.

Try a Vanilla Glaze Finish

For a sweeter bakery-style twist, drizzle the cooled cookies with a simple vanilla glaze instead of chocolate. This keeps the cookie base light and buttery while adding a soft, pretty finish that still works well with the hazelnut center and flaky sea salt.

Make Them Even More Bakery Style

For a more dramatic Crumbl-style presentation, make the cookies slightly larger and taller before baking. This variation helps create an even thicker cookie with a softer center and a more impressive bakery-style look.

🍪 Storage and Make-Ahead Tips

How to Store Crumbl Hazelnut Sea Salt Cookies

Store these Crumbl Hazelnut Sea Salt Cookies in an airtight container at room temperature for up to 3 days. This helps keep the cookies soft and chewy while protecting the gooey hazelnut center from drying out too quickly.

Refrigerate for Longer Freshness

If you want to keep the cookies fresh a little longer, store them in an airtight container in the refrigerator for up to 5 days. Let the cookies come to room temperature before serving, or warm them slightly to soften the hazelnut center again.

Freeze Baked Cookies for Later

These bakery-style hazelnut sea salt cookies also freeze well after baking. Let them cool completely, then place them in an airtight container or freezer-safe bag and freeze for up to 2 months. Thaw at room temperature before enjoying.

Make the Dough Ahead of Time

You can shape the stuffed cookie dough balls ahead of time and keep them covered in the refrigerator for up to 24 hours before baking. This is a great option if you want to prep these Crumbl copycat cookies in advance for parties, holidays, or busy baking days.

Freeze the Dough Balls

For a longer make-ahead option, freeze the shaped cookie dough balls on a tray until firm, then transfer them to a freezer-safe container or bag. Bake from frozen, adding a couple of extra minutes to the baking time as needed.
