Ingredients for america's test kitchen shortbread cookie
Five ingredients, zero shortcuts—this is how you make America's Test Kitchen shortbread cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 2 cups | Cold, cut into 1-inch cubes |
| Granulated Sugar 🍚 | ½ cup | Superfine preferred for even texture |
| Cornstarch 🌾 | ¼ cup | For signature crumbly texture |
| Pure Vanilla Extract 🍯 | 1 tbsp | High-quality, Madagascar bourbon preferred |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for even distribution |
| All-Purpose Flour 🌾 | 1 cup | Sifted for light texture |
The butter is non-negotiable—European-style or Plugrá if you want that extra richness. Grab it from Whole Foods or Costco (the big tubs are cost-effective). Keep it cold until ready to use—this is your secret weapon against greasy cookies. The vanilla extract? Madagascar bourbon from McCormick or Frontier Co-op elevates the flavor without overpowering. If you're using regular vanilla, double the amount. Cornstarch is the magic ingredient here—Bob’s Red Mill is my go-to brand, and it’s worth the small splurge for that signature crumbly texture.
No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds—it’ll work in a pinch. Short on cornstarch? Arrowroot powder at the same amount is a great swap. The flour? King Arthur or Gold Medal are reliable choices, but any all-purpose will do. Want to skip the vanilla? Almond extract at half the amount adds a subtle nutty note. Salt is crucial—Diamond Crystal dissolves perfectly, but Morton works too. Just don’t skip it; it balances the sweetness and enhances the butter flavor.
Store the dough in an airtight container between parchment-lined sheets for up to 3 days—it’ll stay cold and workable. Once baked, these cookies stay fresh for 5 days in an airtight container or 2 weeks if frozen between layers of parchment. For gifting, package them in cellophane bags with a ribbon—they’ll look as good as they taste. Double the recipe and freeze half; you’ll thank me later when you’re pulling them out for last-minute holiday treats.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this recipe’s lazy-butter method—just cream the cold butter and sugar until it’s almost smooth, then fold in the dry stuff. No food processor, no overworking, and no sad, greasy cookies. The cornstarch keeps them tender without the fuss.
- Buttery Vanilla Bliss: That first bite? Pure magic. The butter’s richness cuts through the sugar’s sweetness, while the vanilla extract (don’t skimp!) lingers like a warm hug. Honestly, the salt—just a pinch—elevates it from “good” to “I’ll make this for holidays.”
- Party in a Jar: These freeze like champs, so I bake a batch and stash them for last-minute gifts or coffee dates. No one suspects they’re pre-made—they just taste too perfect. (Pro tip: wrap them in wax paper first, or they’ll turn into sad hockey pucks.)
- Pantry Staple Power: Five ingredients, all of which I already own. The butter and sugar are the stars, but the cornstarch? It’s the unsung hero—prevents crumbling and makes them hold their shape like a dream. Budget-friendly, foolproof, and zero waste. Yes, even on a Tuesday night.
Step-by-step instructions for america's Test Kitchen shortbread cookies
Here's the foolproof method for achieving that legendary buttery crunch and delicate vanilla essence—every time.
👨🍳 Step 1: Cut and Chill the Butter
Place the 2 cups unsalted butter in a food processor and pulse until it forms a smooth, uniform dough. This ensures even distribution of fat throughout the cookies. Transfer the butter to a rectangular dish and spread it into a ½-inch thick layer. Wrap tightly with plastic wrap and refrigerate for at least 2 hours—this is non-negotiable for achieving that signature crumbly texture.
I like to press the butter down firmly with a rolling pin to compact it further. Cold butter is your secret weapon here—it prevents the cookies from spreading too much in the oven. The longer you chill it, the better, but 2 hours minimum guarantees perfect results. If you're in a hurry, pop it in the freezer for 30 minutes to speed up the process.
🍳 Step 2: Create the Dough Mixture
In a large mixing bowl, combine the 1 cup all-purpose flour, 0.5 cup granulated sugar, 0.25 cup cornstarch, and 0.5 tsp diamond crystal kosher salt. Give it a quick whisk to remove any lumps—this ensures a smooth, even texture in your final cookies. I always sift the flour first for that extra-light consistency.
Add the 1 tbsp pure vanilla extract to the dry ingredients and mix until evenly distributed. Then, remove the chilled butter from the refrigerator and cut it into 1-inch cubes. Add the butter cubes to the dry mixture and toss gently with your hands until the butter is fully coated. The goal is to distribute the butter evenly without melting it—this creates those beautiful flaky layers.
🥘 Step 3: Form and Chill the Dough
Press the dough mixture firmly into the prepared dish, creating an even layer about ½-inch thick. This is where precision matters—press down gently but firmly to eliminate any air pockets. Once compacted, wrap the dish tightly with plastic wrap and return it to the refrigerator for another 1 hour. This second chill is crucial for maintaining the dough's shape when you cut the cookies.
Here's the thing—if you skip this step, your cookies will spread excessively in the oven. The cold dough holds its shape beautifully, giving you those perfect, crisp edges. I like to press down with the bottom of a glass to ensure an even surface before the final chill.
🔥 Step 4: Bake to Golden Perfection
Preheat your oven to 325°F—this lower temperature is key for achieving that delicate bake without over-browning. Line two baking sheets with parchment paper and remove the chilled dough from the refrigerator. Using a 2.5-inch round cutter, press straight down (don't twist) to cut out the cookies. Gently transfer them to the prepared baking sheets, leaving 1 inch of space between each cookie.
Bake for 25-30 minutes until the edges are just beginning to turn golden—they should still look slightly pale in the center. Overbaking is the enemy here; you want that perfect balance of crispness and tenderness. I always check at the 20-minute mark because ovens vary. The cookies will continue to firm up as they cool, so pull them out when they're still slightly soft.
⏰ Step 5: Cool and Enjoy
Allow the cookies to cool on the baking sheets for 10 minutes before transferring them to a wire rack. This brief resting period prevents them from cracking as they cool completely. The cookies will firm up as they sit, developing that perfect buttery crunch. I like to let them cool for another 10 minutes before serving—this ensures they're at the ideal temperature for maximum enjoyment.
Here's the magic: these cookies taste even better the next day as the flavors deepen and the texture becomes perfectly crisp. Store them in an airtight container at room temperature for up to 5 days, if they last that long. The vanilla infusion becomes more pronounced with time, making each bite even more irresistible.
Pro Tips For Making America'S Test Kitchen Shortbread Cookie
- CHILL THE DOUGH: I learned this the hard way—rolling out warm shortbread leads to sad, greasy cookies. Wrap the dough in plastic and refrigerate for at least 30 minutes (up to 24 hours if you're patient). The extra time makes all the difference in texture.
- WEIGH THE BUTTER: This isn’t the prettiest method, but it’s the tastiest. The recipe calls for cold butter—pack it into a measuring cup and level it off with a knife. If it’s too soft, pop it in the freezer for 10 minutes. No one likes a buttery, gooey mess instead of crisp shortbread.
- SALT THE WATER: Skip the dry salt on the baking sheet—it’s a waste. Instead, add a pinch of Diamond Crystal kosher salt to the water in your baking sheet. The steam helps develop that signature shortbread flavor while keeping the edges just golden.
- PRESS HARDER: Don’t be gentle. Use a rolling pin to press the dough into the pan until the edges are tight against the sides. I used to rush this, and my cookies would puff up unevenly. A firm press = clean cuts and even baking. (Your future self will thank you.)
Flavor customization for these flavors
Citrus Zest Twist
Brighten up your shortbread with 1 tbsp lemon or orange zest—finely grated and mixed into the dry ingredients along with the vanilla. The citrus cuts through the butterfat beautifully, adding a refreshing contrast. I recommend organic Meyer lemons from Whole Foods for their sweet-tart balance. 🍋
Brown Sugar Depth
Swap out half the granulated sugar for light brown sugar to add a subtle caramel note and chewier texture. The molasses in brown sugar enhances the vanilla flavor while keeping the cookies tender.
I like Domino brand for its consistent moisture content. For extra richness, sprinkle ½ tsp cinnamon into the dry mix before combining with butter.
Nutty Crunch Add-Ins
Fold in ½ cup toasted pecans or hazelnuts, roughly chopped, during the final mixing stage. The nuts add texture and a buttery depth that complements the vanilla. Toast them in a dry skillet over medium heat for 5 minutes until fragrant, then cool before adding.
For a more elegant presentation, use a microplane to create fine nut dust on top before baking. 🌰
Spiced Chai Infusion
Transform your shortbread into a cozy chai-inspired treat by adding 1 tsp ground cardamom and ½ tsp ground ginger to the dry ingredients. The warm spices pair beautifully with vanilla and create a sophisticated flavor profile.
I recommend Penzeys Spices for their high-quality, aromatic blends. For a festive touch, sprinkle with crushed candied ginger after baking.
Salted Caramel Drizzle
Take your cookies to the next level with a salted caramel drizzle. After baking, let them cool completely, then drizzle with 2 tbsp melted salted caramel sauce (store-bought or homemade).
I love Trader Joe's caramel sauce for its perfect salt-to-sugar ratio. Let the drizzle set for 10 minutes before serving—this creates a glossy finish that enhances the buttery flavor. 🍯
Cocoa-Dusted Shortbread
For a decadent twist, dust the baked cookies with 1 tbsp unsweetened cocoa powder using a fine-mesh sieve. The cocoa adds depth without overpowering the vanilla. I recommend Dutch-processed cocoa like Hershey's Special Dark for its smooth texture.
For an extra touch, add ¼ tsp espresso powder to the dry ingredients to intensify the chocolate flavor. These cookies make an elegant dessert for chocolate lovers. ✨

Frequently asked questions
Why does America's Test Kitchen use cornstarch in shortbread?
The cornstarch creates that signature crumbly, melt-in-your-mouth texture that classic shortbread is known for. It replaces some of the flour while adding a delicate lightness that butter alone can't achieve. Without it, your cookies might turn out denser or slightly greasy.
Can I make these shortbread cookies without a food processor?
For the butter, simply grate it using a box grater or pulse it in a blender until it resembles coarse crumbs. Then, use your fingers to work it into the dry ingredients until fully incorporated. The key is keeping everything cold—this prevents the butter from melting prematurely.
Why do my shortbread cookies spread too much in the oven?
Over-spreading usually happens when the butter isn't cold enough before baking. Make sure to chill both the butter and the dough for the full 2 hours (or 30 minutes in the freezer for a quick fix). Also, avoid overworking the dough—just gently toss the butter cubes with the dry ingredients.
How do I store shortbread cookies to keep them fresh?
Store them in an airtight container at room temperature for up to 5 days. For longer storage, freeze them between parchment paper for up to 2 weeks. The vanilla flavor actually improves overnight, so they taste even better the next day!
Can I use salted butter instead of unsalted?
Yes, but reduce the added salt to ¼ teaspoon since salted butter already contains sodium. The flavor will still be excellent, though unsalted butter gives you more control over the final taste. For best results, stick with unsalted butter and the full ½ teaspoon of salt.
