Ingredients for america's test kitchen shortbread cookie
Buttery, crisp-edged shortbread with tender centers—just 12 ingredients transform simple pantry staples into bakery-perfect cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| European-Style Unsalted Butter 🧈 | 1 cup | Cold, cubed for even baking |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, spooned and leveled |
| Granulated Sugar 🍚 | ¼ cup | Superfine preferred for smooth texture |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Vanilla Extract 🌿 | 1 tsp | Pure alcohol-free preferred |
| Lemon Zest 🍋 | 1 tsp | Fresh, finely grated |
| Cookie Cutters (Optional) 🎃 | 1 set | For festive shapes, 2-inch diameter |
| Cornstarch 🌾 | 1 tbsp | For extra tenderness |
| Heavy Cream (Optional) 🥛 | 1 tbsp | For extra richness |
| Almond Extract (Optional) 🌰 | ½ tsp | For nutty depth |
| Powdered Sugar (Optional) 🍚 | ¼ cup | For dusting finished cookies |
| Flaky Sea Salt (Optional) 🧂 | 1 tsp | For finishing |
The butter is non-negotiable. European-style like Plugrá or Miyoko's has higher fat content, which gives those signature crisp edges. Grab it from Whole Foods or Williams Sonoma if you can't find it at your regular grocery store. Keep it cold—cold butter is your friend here. The flour? King Arthur or Bobs Red Mill are reliable, but any all-purpose will work. Sift it, though—those little lumps ruin the texture. I always measure mine by spooning it into the cup and leveling with a knife. The sugar? Superfine if you can find it, but regular granulated works if you pulse it in a food processor for 10 seconds.
No European butter? Land O'Lakes European-style is a decent substitute, though it's not quite the same. Short on vanilla? Almond extract at half the amount adds depth without overpowering. The lemon zest can be zested from a Meyer lemon if you want extra sweetness, or regular lemons if that's what you've got. For the optional cornstarch, Arrowroot powder works too—just use the same amount. The cookie cutters? Wilton makes great ones, but any 2-inch shape will do. Pro tip: Chill your dough for at least 1 hour—this prevents spreading and ensures those perfect crisp edges.
Store the dough in the fridge for up to 2 days if you're prepping ahead. Baked cookies keep in an airtight container for 5 days at room temperature, or freeze for 3 months for maximum freshness. I like to portion the dough into balls before baking, then freeze them on a tray before transferring to a bag. That way, I can bake straight from frozen—just add 2 extra minutes to the bake time. The powdered sugar and flaky salt are just for finishing, but they make all the difference. Sprinkle them on right after baking while the cookies are still warm.

Step-by-step instructions for america's test kitchen shortbread cookies
Here's how to achieve that signature buttery crunch and tender crumb—every time.
Cut and Chill the Butter for Perfect Texture
Place the 1 cup European-Style Unsalted Butter in a food processor and pulse until it resembles coarse crumbs with some pea-sized pieces remaining. This texture is crucial—it creates the signature shortbread crumb without losing that melt-in-your-mouth quality. If using optional 1 tbsp Heavy Cream, add it now and pulse briefly to combine.
Transfer the butter to a mixing bowl and refrigerate for 15 minutes while you prepare the dry ingredients. Cold butter is essential—it prevents the cookies from spreading too much in the oven. I like to press the butter against the sides of the bowl to ensure even chilling throughout.
Combine Wet and Dry Ingredients for Smooth Dough
In the same bowl with the chilled butter, add the 1.5 cups All-Purpose Flour, 0.25 cup Granulated Sugar, 0.5 tsp Diamond Crystal Kosher Salt, 1 tbsp Cornstarch, 1 tsp Vanilla Extract, and 1 tsp Lemon Zest. Use a wooden spoon to gently fold everything together until the mixture resembles wet sand.
Here's where precision matters: Add the optional 0.5 tsp Almond Extract if using, and mix just until combined. Overmixing develops gluten, which makes shortbread cookies tough. The dough should hold together when pressed but still be slightly crumbly—this is perfect for shortbread's signature texture.
Shape and Chill the Dough for Clean Edges
Turn the dough onto a lightly floured surface and gently press it into a 1-inch thick rectangle. Wrap tightly in plastic wrap and refrigerate for at least 1 hour or up to 24 hours. This resting period relaxes the gluten and firms up the dough, ensuring clean edges when you cut the cookies later.
I always use the optional cookie cutters at this stage for festive shapes. If skipping them, use a 2-inch round cutter for classic shortbread. Press firmly but don't force the dough through the cutter—this prevents crumbling. Re-chill shaped cookies on a parchment-lined tray for 15 minutes before baking.
Bake to Golden Perfection for Crisp Edges
Preheat your oven to 325°F—this lower temperature ensures even baking without burning the edges. Place shaped cookies on the prepared tray, spacing them 1 inch apart. Bake for 18-22 minutes until the edges are golden brown and the centers look slightly underbaked.
Here's the critical checkpoint: The cookies should be set but still soft to the touch. They'll firm up as they cool. If using 1 tsp Flaky Sea Salt, sprinkle it over the hot cookies immediately after removing from the oven. For extra richness, dust with 0.25 cup Powdered Sugar while still warm.
Cool and Store for Maximum Freshness
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This brief rest prevents them from becoming soggy. For best texture, serve at room temperature—the contrast between crisp edges and tender centers develops fully after cooling.
Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. The butter content makes these cookies best enjoyed fresh, but they'll maintain their texture beautifully when properly stored. The lemon zest and vanilla infuse deeper as they sit, making flavors more pronounced with each bite.
Pro Tips For Making America'S Test Kitchen Shortbread Cookie
- Chill the Dough: DESCRIPTION: Stick the dough in the fridge for at least 2 hours—no, 4 is better. I used to skip this, thinking it was optional, but the cookies spread less and hold their shape like they’re supposed to. Cold butter behaves, and that’s what you want here.
- Measure Salt Precisely: DESCRIPTION: Diamond Crystal kosher salt is fluffy—don’t eyeball it. Use the ¼ teaspoon called for, or your cookies will taste flat. I learned this after making a batch that tasted bland, then realized I’d used half the amount.
- Cut Butter, Don’t Melt: DESCRIPTION: Cold butter cubes into the flour mixture—no melting allowed. This recipe relies on the butter staying solid until it hits the oven. If you melt it first, you’ll end up with a dense, greasy mess instead of crisp shortbread.
- Press, Don’t Pack: DESCRIPTION: When shaping the dough into logs or rounds, press gently but firmly—just enough to hold together. Packing too hard makes the cookies dense. My first batch looked like hockey pucks until I realized I’d gone overboard.
Dietary considerations for this america's test kitchen shortbread cookie
Gluten-Free Adaptation
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free flour blend like King Arthur Measure for Measure. Add 1 extra tbsp xanthan gum to mimic gluten's binding properties.
Chill the dough for 2 hours—gluten-free dough spreads more easily. Bake at 300°F instead of 325°F for 20-24 minutes to prevent over-browning. 🌾
Refined Sugar-Free
Swap the 0.25 cup granulated sugar for 0.25 cup coconut sugar or 0.2 cup monk fruit sweetener. Reduce vanilla extract to ½ tsp—natural sweeteners intensify flavors.
For extra moisture, add 1 tbsp almond milk to the dough. These cookies stay tender longer but develop crisp edges more slowly—bake for 24-28 minutes. 🍚
Dairy-Free Version
Use 1 cup dairy-free butter substitute like Miyoko's Vegan European-Style Butter or Earth Balance Buttery Sticks. Replace heavy cream with 1 tbsp coconut cream if using.
For richness, add 2 tbsp dairy-free milk powder to the flour mixture. The texture will be slightly less crisp but still delightfully tender. 🧈
Nut-Free Options
Omit the almond extract entirely. Boost vanilla to 1.5 tsp and add ½ tsp orange zest for depth. For extra tenderness, increase cornstarch to 2 tbsp. These cookies maintain their signature crumb while avoiding all nut-based ingredients. The lemon flavor shines even brighter without competition. 🍋
Lower-Calorie Adjustments
Reduce butter to ½ cup and add ¼ cup unsweetened applesauce to maintain moisture. Use 0.2 cup erythritol blend instead of sugar. For structure, add 1 tbsp vital wheat gluten (if not gluten-free). These lighter cookies still deliver satisfying texture but with 30% fewer calories. 💪
Allergen-Free Packaging
Always bake on parchment-lined trays to prevent cross-contamination. Use separate utensils for gluten-free and nut-free batches. Store finished cookies in airtight containers with allergen labels. For gifting, package individually in cellophane bags with clear allergen warnings. Safety first—especially when sharing these treats! ✨

Frequently asked questions
Why does America's Test Kitchen recommend chilling the butter before mixing?
Chilling the butter prevents the cookies from spreading too much during baking. The cold fat creates those signature crisp edges while maintaining a tender center. Skipping this step often results in flat, cake-like cookies instead of the classic shortbread shape. Press the butter against the bowl sides for even chilling—this ensures consistent texture throughout.
Can I use regular butter instead of European-style?
Regular butter will work, but you'll lose some of that signature crispness. European-style butter has a higher fat content (about 82-84% fat vs. 80% in regular butter), which gives shortbread its iconic texture. For best results, use Land O'Lakes European-style butter if you can't find the specialty version. The difference is subtle but noticeable in professional-quality results.
How do I get the perfect crisp edges without burning?
Bake at 325°F for 18-22 minutes—this lower temperature prevents burning while allowing the edges to crisp properly. The cookies should be golden brown at the edges but still slightly soft in the center when removed. Let them cool on the baking sheet for 5 minutes before transferring—they'll firm up as they cool, giving you that perfect contrast between crisp and tender.
What's the best way to store these cookies to maintain freshness?
Store in an airtight container at room temperature for up to 5 days. For longer storage, freeze shaped cookies on a tray before transferring to a bag—they'll keep for 3 months. The butter content makes them best enjoyed fresh, but proper storage prevents them from becoming soggy. Avoid refrigerating unless storing for more than 3 days—condensation ruins the texture.
Can I make these cookies without a food processor?
Yes! Use a box grater to shred the cold butter into pea-sized pieces, then mix by hand with a fork until the mixture resembles wet sand. The key is to keep everything cold—work quickly and refrigerate the dough for the full 1 hour before shaping. The texture will be slightly less uniform but still delicious. For extra tenderness, pulse the cornstarch with the flour before mixing.
