This chocolate chunk shortbread cookie recipe makes tender, buttery cookies with crisp sugar-coated edges, pale centers, irregular chocolate pockets, and a finishing sprinkle of flaky sea salt. To make them, mix softened butter with two kinds of sugar, add vanilla and flour, fold in coarsely chopped chocolate, shape the dough into two logs, chill for at least 2 hours, slice, and bake at 350°F (175°C) for 12–15 minutes.
The secret to cookies that truly melt in your mouth is restraint: do not overmix the dough, do not skip the chilling time, and do not wait for the cookies to become deeply brown. Their centers should remain somewhat pale while the edges turn lightly golden, creating the delicate shortbread texture that makes every bite buttery, crisp, and wonderfully tender.

These cookies bring together the best qualities of shortbread and a chocolate-loaded bakery cookie. The dough is rich without being fussy, the coarse-sugar coating adds a delicate crunch, and flaky salt keeps the sweetness balanced from the first bite to the last.
Unlike many drop cookies, this recipe is prepared as slice-and-bake logs. That method makes it easy to prepare the dough in advance, chill it overnight, and bake fresh rounds whenever you want a warm batch.
Chopped chocolate is especially important here. Uniform chips can work, but irregular chunks create thin chocolate shards, small flecks, and generous melted pockets scattered throughout each buttery cookie.
If you enjoy chocolate-forward treats with contrasting textures, you may also like these chocolate crinkle cookies. They have a softer, fudgier character, while these shortbread rounds stay crisp at the edges and tender in the center.
Ingredients You’ll Need
Because the ingredient list is short, each item has a clear role. Use good-quality butter and chocolate, and measure the flour carefully so the cookies stay delicate rather than dry.
- Unsalted butter: One cup, or 227 grams, provides the rich flavor and tender crumb. Let it soften to room temperature so it blends smoothly with the sugars.
- Granulated and light brown sugar: The granulated sugar helps create a crisp bite, while the brown sugar adds gentle moisture and a deeper caramel note.
- Vanilla extract: One teaspoon rounds out the buttery flavor and complements the chocolate.
- All-purpose flour: Use 2 1/4 cups, about 285–293 grams. Add it only until the dough comes together.
- Bittersweet or semisweet chocolate: Six ounces of coarsely chopped chocolate gives the cookies their dramatic chocolate texture.
- Egg, coarse sugar, and flaky sea salt: The beaten egg helps the Demerara sugar cling to the logs, while the sugar and salt create the signature crisp, sweet-salty exterior.

How to Make It Step-by-Step
Step 1: Bring the butter to room temperature before beginning. It should feel soft when pressed but should not be melted or oily, because melted butter can make the dough spread more than intended.
Step 2: Beat the butter, granulated sugar, and packed light brown sugar until smooth and well combined. This usually takes a few minutes with an electric mixer, and the mixture should look creamy rather than grainy.
Step 3: Mix in the vanilla extract. Scrape down the sides of the bowl so the flavor is evenly distributed through the butter mixture.
Step 4: Add the all-purpose flour and mix just until a cohesive dough forms. Stop as soon as no obvious dry streaks remain, since overmixing can make shortbread less tender.
Step 5: Fold in the coarsely chopped chocolate by hand. A spatula helps distribute both the fine shards and larger chunks without working the dough more than necessary.
Step 6: Divide the dough into two equal portions and shape each into a log roughly 2 to 2 1/2 inches in diameter. Roll gently on the counter to smooth the shape, but do not compress the dough aggressively.
Step 7: Brush the outside of each log with beaten egg, then roll the logs in Demerara or another coarse sugar. Wrap them tightly and refrigerate for at least 2 hours; overnight chilling is also perfectly suitable.
Step 8: Heat the oven to 350°F (175°C) and line baking sheets with parchment paper. Slice the firm logs into rounds about 1/2 inch thick, using a sharp knife and a gentle sawing motion for clean edges.
Step 9: Arrange the rounds on the prepared sheets, leaving space between them for slight spreading. Sprinkle each cookie with flaky sea salt before baking.
Step 10: Bake for 12–15 minutes per batch. Look for lightly golden edges and centers that remain somewhat pale; deeply browned shortbread will be firmer and less delicate.
Step 11: Leave the cookies on the baking sheet for several minutes after removing them from the oven. Transfer them to a wire rack once they have begun to set, remembering that they become firmer as they cool.
Pro Tips for Tender, Buttery Cookies
The most important tip is to chill the dough thoroughly. Firm logs are easier to slice, hold their round shape better, and are less likely to spread excessively in the oven.
If the dough feels too soft to cut, return it to the refrigerator rather than adding extra flour. Additional flour can make the finished cookies heavy and mute the buttery texture.
Use a sharp chef’s knife or serrated knife for slicing. If chocolate pieces cause a round to crumble slightly, press the edge back together with your fingers before placing it on the baking sheet.
Do not judge doneness by the centers alone. These cookies should look pale in the middle, and the edges should be only lightly golden. They may seem delicate when first removed from the oven, but they firm as they cool.
For a festive cookie tray, pair them with our eggnog cookies. The warm spice profile offers a pleasant contrast to the bittersweet chocolate and sea salt.
Serving, Storage, and Make-Ahead Ideas
Serve these shortbread cookies at room temperature with coffee, tea, hot chocolate, or a glass of cold milk. They are also lovely alongside vanilla ice cream, where the crisp cookie and melting dessert create a satisfying contrast.
The unbaked logs can be chilled overnight, making them useful for entertaining and holiday baking. Slice only what you need, then return the remaining wrapped dough to the refrigerator until you are ready to bake it.
Store fully cooled cookies in an airtight container at room temperature. Keep parchment between layers if the sugar coating is especially generous, and avoid storing them while warm because trapped steam can soften the crisp exterior.
For a colorful addition to a dessert platter, consider serving these beside our chocolate glitter cookies. The two cookies share a chocolate-rich profile but offer distinctly different textures.
Common Questions About Chocolate Chunk Shortbread
Can I use chocolate chips? Yes, but coarsely chopped bittersweet or semisweet chocolate is recommended. Chopped chocolate creates a more varied bite with thin shards and larger melted pockets.
Why did my cookies spread? The dough may not have been chilled long enough, or the butter may have been too warm. Chill the logs until firm and make sure the baking sheets are not warm before arranging the slices.
Why are the centers pale? Pale centers are expected and desirable in this recipe. The cookies are ready when the edges are lightly golden, because baking until the entire cookie is deeply brown can reduce its tender texture.
Can I make thinner cookies? You can slice the logs thinner, but the yield will increase beyond the usual 24–36 cookies and the baking time may need close watching. The stated 1/2-inch slices provide a balanced crisp edge and tender center.

- Add the flour and mix just until a cohesive dough forms. Avoid overmixing, then fold in the coarsely chopped chocolate.
- Divide the dough in half and shape each portion into a log about 2 to 2 1/2 inches in diameter. Brush the outside of each log with beaten egg and roll it in coarse sugar.
- Wrap the logs and refrigerate them until firm for at least 2 hours; chilling overnight is fine.
- Heat the oven to 350°F (175°C). Slice the chilled logs into rounds about 1/2 inch thick and arrange them on parchment-lined baking sheets with space between each cookie.
- Sprinkle the rounds with flaky sea salt and bake for 12–15 minutes per batch, until the edges are lightly golden and the centers still look somewhat pale.
- Cool the cookies on the baking sheet for several minutes before transferring them to a wire rack. They will firm as they cool.
Notes
Final Thoughts
This chocolate chunk shortbread cookie recipe is a dependable choice when you want a polished homemade treat without complicated decorating or unusual ingredients. The buttery dough, coarse-sugar crust, irregular chocolate pieces, and flaky salt create a cookie that feels simple yet especially satisfying.
Give the logs the full chilling time, slice them about 1/2 inch thick, and remove the cookies while their centers are still pale. Once cooled, each round should offer a delicate snap at the edge, a tender middle, and enough chocolate to make every bite worth savoring.
Keep one log chilled for a spontaneous batch, or bake both for a cookie tin, holiday platter, afternoon gathering, or edible gift. These cookies are at their best when completely cool, but sharing one while the chocolate is still slightly soft is an irresistible option.
