The appeal

Why you’ll love it

The combination of softened butter and vegetable oil creates a dough that is exceptionally tender and easy to work with. The cornstarch further contributes to the delicate, melt-in-your-mouth texture by inhibiting gluten formation, resulting in a fine, sandy crumb. Kneading the dough gently ensures that the cookies remain light and not tough, while the ground walnuts and sesame seeds add layers of nutty flavor and a pleasant crunch.
Baking the cookies at a moderate temperature allows them to set without browning too much, preserving their pale, buttery appearance. The short baking time keeps the interior moist and tender, while the edges become just slightly crisp. Dipping the cooled cookies in chocolate creates a firm, glossy shell that contrasts beautifully with the soft crumb. The chocolate also adds a touch of bitterness that balances the sweetness of the dough, making each bite perfectly harmonious.

Notes

Use unsalted butter so you can control the salt level. The vegetable oil helps keep the dough soft even after refrigeration. Powdered sugar dissolves quickly and creates a smoother texture than granulated sugar. Cornstarch is key for that sandy, crumbly texture, so don't skip it. Finely ground walnuts are best; you can pulse them in a food processor until they resemble coarse sand. Toasted sesame seeds add a nutty, slightly smoky flavor—toast them in a dry skillet over medium heat until fragrant and lightly golden.

For the chocolate dip, use good-quality dark chocolate with at least 60% cacao for the best flavor and snap. You can also use chocolate chips, but they may need a little vegetable shortening to help them melt smoothly. If you prefer a sweeter cookie, use milk chocolate. The cookies are delicious without the chocolate too, but the dip adds a lovely finish. Store the cookies in an airtight container at room temperature for up to a week, or freeze for longer storage.

Prep

Before you start

Before starting, ensure the butter is softened to room temperature. Measure all ingredients accurately. Line two baking sheets with parchment paper. Have the ground walnuts and toasted sesame seeds ready. Melt the chocolate only after the cookies are completely cooled. Preheat the oven to 350°F (175°C) when you are ready to bake. Gather your mixing bowl, wooden spoon, and baking sheets so everything is within reach.

Step by step

Method

7 steps

Phase 1

Dough and Shaping

Step 1: Make the Shortbread Dough
In a large bowl, knead the softened butter, vegetable oil, powdered sugar, cornstarch, vanilla extract, and all-purpose flour until a soft, cohesive dough forms. The dough should be pliable and not sticky. If it feels too dry, add a teaspoon of water at a time, but the dough should come together smoothly with gentle kneading.
You’ll need: unsalted butter, softened · vegetable oil · powdered sugar · cornstarch · vanilla extract · all-purpose flour
Look for: The dough is soft, smooth, and holds together without cracking.
Tip: Knead just until combined; overworking can make the cookies tough.
Step 2: Add Walnuts and Sesame Seeds
Fold the finely ground walnuts and toasted sesame seeds into the dough until evenly distributed. The dough will become speckled with the nuts and seeds. Continue to knead gently just until they are incorporated throughout.
You’ll need: finely ground walnuts · toasted sesame seeds
Look for: The nuts and seeds are evenly dispersed in the pale dough.
Tip: Toasting the sesame seeds beforehand deepens their nutty flavor.
Step 3: Shape the Cookies
Roll the dough into small walnut-sized balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper, spacing them about 1 inch apart. For a more oval shape, gently press each ball to flatten slightly.
You’ll need: unsalted butter, softened · vegetable oil · powdered sugar · cornstarch · vanilla extract · all-purpose flour · finely ground walnuts · toasted sesame seeds
Look for: The dough balls are uniform and smooth.
Tip: Chill the dough for 15 minutes if it becomes too soft to handle.

Checkpoint

At the end of this phase, you should have a smooth, pliable dough that holds together without sticking to your hands. The walnuts and sesame seeds should be evenly distributed, creating a speckled appearance. The dough balls should be uniform in size, about 1 inch in diameter, and smooth on the surface. If the dough feels too soft, chill it briefly before shaping.

Phase 2

Baking and Cooling

Step 4: Bake the Cookies
Preheat the oven to 350°F (175°C). Bake the cookies for 12 to 15 minutes, or until the edges are lightly golden. The tops should remain pale. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
You’ll need: unsalted butter, softened · vegetable oil · powdered sugar · cornstarch · vanilla extract · all-purpose flour · finely ground walnuts · toasted sesame seeds
Look for: The cookies are set, with slightly golden edges and a pale center.
Tip: Do not overbake; the cookies continue to firm up as they cool.
Step 5: Cool the Cookies Completely
Allow the baked cookies to cool completely on a wire rack. This is essential before dipping in chocolate, as warm cookies will cause the chocolate to melt and slide off. Cooling also helps the cookies develop their characteristic sandy, crumbly texture.
You’ll need: unsalted butter, softened · vegetable oil · powdered sugar · cornstarch · vanilla extract · all-purpose flour · finely ground walnuts · toasted sesame seeds
Look for: The cookies are completely cool to the touch and firm.
Tip: For a crisper texture, let them cool for at least 30 minutes.

Checkpoint

After baking, the cookies should be lightly golden at the edges but still pale on top. They will feel firm and slightly crisp. Allow them to cool completely on a wire rack; they should be cool to the touch and have a dry, sandy texture. The cookies should not be soft or doughy in the center. Once cooled, they are ready for dipping.

Phase 3

Chocolate Dip and Set

Step 6: Dip in Melted Chocolate
Melt the dark chocolate in a heatproof bowl set over a pot of simmering water, or in the microwave in 20-second bursts, stirring until smooth. Dip one half of each cooled cookie into the melted chocolate, letting any excess drip off. Place the dipped cookies on a parchment-lined baking sheet.
You’ll need: dark chocolate, melted
Look for: The chocolate coats the cookie evenly and drips off cleanly.
Tip: If the chocolate thickens, reheat gently to keep it fluid.
Step 7: Let the Chocolate Set
Allow the chocolate-dipped cookies to set at room temperature on the parchment paper for about 20 minutes, or until the chocolate is firm. For a quicker set, place the tray in the refrigerator for 10 minutes. Once set, the chocolate will be glossy and crisp.
You’ll need: dark chocolate, melted
Look for: The chocolate is firm and no longer tacky to the touch.
Tip: Avoid touching the chocolate while it sets to keep the surface glossy.

Checkpoint

The chocolate should be smooth and glossy, coating the cookies evenly. After setting, the chocolate will be firm and not tacky. When you break a cookie in half, the chocolate snaps cleanly, revealing the sandy, nutty crumb. The cookies should look elegant with a beautiful contrast between the pale shortbread and dark chocolate.

Doneness

How to tell it’s done

The cookies are done when the edges are just barely golden and the tops are still pale. They will look slightly puffed and feel firm to the touch. A toothpick inserted into the center should come out clean. The cookies will continue to set as they cool, so avoid overbaking. Once cooled, they should have a delicate, sandy texture that crumbles easily but holds together when bitten. The chocolate dip should be set and glossy, with a clean snap when you break the cookie in half.

Avoid these

Common mistakes

One common mistake is overworking the dough, which can develop gluten and result in tough cookies. Knead just until the ingredients are combined. Another is using cold butter, which makes the dough hard to mix. Ensure the butter is properly softened. Overbaking is another pitfall—watch the cookies closely and remove them as soon as the edges color. Also, dipping warm cookies in chocolate will cause the chocolate to melt and slide off, so always cool them completely. Finally, if the chocolate seizes or becomes grainy, it may have come into contact with water, so keep all utensils dry.

Better results

Tips

Tip 1
For the best texture, make sure the butter is truly soft—this allows the dough to come together without overworking. If you don't have a food processor, you can grind the walnuts by placing them in a zip-top bag and crushing them with a rolling pin. Toasting the sesame seeds brings out their nutty flavor; just watch them closely as they can burn quickly. When melting chocolate, do it gently and stir frequently to ensure a smooth, lump-free consistency.
Tip 2
To get a clean, even chocolate dip, use a fork to hold the cookie and dip it halfway, letting the excess drip off before placing on parchment. If the chocolate begins to thicken as it cools, reheat it gently. For a decorative touch, sprinkle a few extra sesame seeds or chopped walnuts on the chocolate before it sets. These cookies also make lovely gifts—package them in a tin lined with parchment paper.

Make it yours

Variations

Pecan and Honey

Replace the walnuts with finely ground pecans and add 1 tablespoon of honey to the dough. The honey adds a subtle floral sweetness that pairs beautifully with the chocolate.

Citrus Zest

Add 1 teaspoon of orange zest or lemon zest to the dough along with the vanilla. The bright citrus notes cut through the richness and complement the nutty flavors.

Spiced Shortbread

Add 1/2 teaspoon of ground cinnamon and a pinch of nutmeg to the dry ingredients. The warm spices give the cookies a cozy, holiday feel.

White Chocolate Dip

Swap the dark chocolate for white chocolate and sprinkle with crushed pistachios or dried cranberries before the chocolate sets. This version is sweeter and more festive.

Questions

Frequently asked questions

Can this cookie dough be made ahead of time?

Yes, the dough can be prepared up to 3 days in advance. Shape it into balls and store in an airtight container in the refrigerator. You can also freeze the shaped dough for up to 3 months. When ready to bake, simply place the frozen dough balls on a baking sheet and add a couple of minutes to the baking time.

Why did your cookies spread too much?

If the cookies spread excessively, the dough may have been too warm or the butter too soft. Chilling the shaped dough for 15-20 minutes before baking can help prevent spreading. Also, ensure your baking sheets are cool before placing the dough on them. Using a higher ratio of flour to fat also helps maintain shape.

Can you use salted butter instead of unsalted?

You can, but you may want to reduce or omit any added salt in the recipe. Since the video does not call for salt, salted butter will add a slight saltiness that can be pleasant. However, for the most control over flavor, unsalted butter is recommended.

How do you toast sesame seeds?

Place the sesame seeds in a dry skillet over medium heat. Stir frequently for 2-3 minutes until they become fragrant and lightly golden. Be careful not to burn them, as they can turn bitter. Remove from the pan immediately and let cool before adding to the dough.

Can you skip the chocolate dip?

Absolutely. The shortbread cookies are delicious on their own. If you skip the dip, you can dust them with powdered sugar or leave them plain. Just be aware that the chocolate adds a rich contrast and a beautiful finish, so you might miss it once you try the full version.
