This wheat-free shortbread cookie recipe delivers the same crunchy, sandpaper-like texture as classic shortbread—without the gluten. The secret lies in almond flour and oat flour, which create that signature melt-in-your-mouth crunch while keeping the cookies tender inside.
I’ve perfected this recipe after years of testing, ensuring every bite lives up to the buttery, crumbly promise of traditional shortbread.
The beauty of this recipe is its simplicity: just five core ingredients—no fancy substitutions or complicated techniques. A touch of cornstarch ensures the perfect crumb, while a pinch of salt balances the sweetness.
The dough comes together in minutes, and the baking time is short, so you’ll have golden, buttery cookies ready in under 20 minutes. No gluten means no compromise on flavor or texture.
What sets these cookies apart is their distinctive crunch—almost like biting into fine sandpaper, but with a rich, buttery finish. The edges stay crisp while the centers remain tender, making them ideal for pairing with tea, coffee, or even as a dessert alongside fresh fruit.
The recipe also allows for customization: add vanilla extract for warmth, citrus zest for brightness, or chopped nuts for extra crunch.
Once baked, let the cookies cool completely before cutting into squares—this ensures clean, sharp edges that hold their shape. Store in an airtight container for up to one week, though they rarely last that long.
Whether you’re avoiding gluten or simply craving a classic treat with a modern twist, these cookies deliver restaurant-quality results at home.
Ingredients for wheat free shortbread cookie
Five gluten-free ingredients transform into restaurant-quality shortbread with signature sandpaper crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 cups | Finely ground, unsweetened preferred |
| Oat Flour 🌾 | ½ cup | Blended from certified gluten-free oats |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for even mixing |
| Granulated Sugar 🍚 | ¼ cup | Superfine preferred for smooth texture |
| Cornstarch 🌽 | 2 tbsp | Ensures signature crumb structure |
| Fine Sea Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Pure Vanilla Extract 🌿 | 1 tsp | Optional but enhances flavor |
| Lemon Zest 🍋 | 1 tsp | Brightens flavor profile |
Almond flour is the backbone of this recipe—Bob's Red Mill or Anthony's Goods brands deliver the finest grind for that signature texture. Oat flour must be certified gluten-free; Bob's Red Mill gluten-free oats work perfectly when blended into flour. For butter, Plugrá or European-style unsalted gives the richest flavor. The sugar should be superfine if possible—Domino brand works well, or pulse regular granulated sugar in a food processor. Cornstarch is non-negotiable for achieving that professional crumb structure.
No almond flour? Cashew flour works in a pinch, though texture will differ slightly. Substitute oat flour with rice flour if needed, but expect a denser cookie. For sugar, coconut sugar at 1:1 ratio adds subtle caramel notes. Vanilla extract can be omitted, but if you do, add 0.25 tsp almond extract for depth. Lemon zest can be swapped for orange zest or a pinch of cardamom for warmth. Always use fine sea salt—Diamond Crystal dissolves cleanly without graininess.
Store dough in an airtight container with parchment between layers for up to 3 days in the fridge. Baked cookies keep their crispness for 5-7 days in an airtight container at room temperature. For longer storage, freeze unbaked dough portions for up to 3 months—bake straight from frozen, adding 2-3 minutes to time. Once baked, let cookies cool completely before cutting to maintain their signature sharp edges.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this dough—just fold the almond and oat flours together, then cut in the cold butter until it resembles coarse crumbs. No electric mixer needed, no overworking the dough, and honestly? It’s the kind of recipe where I can have a glass of wine while prepping.
- Buttery Crunch Magic: That crispy edge with the tender crumb? It’s all in the butter-to-flour ratio and the cornstarch trick (trust me, it’s subtle but chef’s kiss). The almond flour adds a nutty depth, while the oat flour keeps it from being too dry—like a hug for your taste buds.
- Double-Duty Cookies: These bake up perfectly for holiday gifts (wrap them in cellophane, tie with ribbon—no one will guess they’re gluten-free) or as a quick afternoon snack. I’ve even crushed the cooled ones into cookie crumble for ice cream—zero waste, maximum flavor.
- Lasts a Week: Between us, I’ve had these sitting in an airtight container for eight days and they still taste fresh. The almond flour keeps them from getting stale, and the sugar caramelizes just enough to stay irresistible. Plus, they’re cheap to make—half the cost of store-bought gluten-free cookies, but way better.
Step-by-step instructions for wheat-free shortbread cookies
Master this gluten-free technique and you'll achieve that signature sandpaper texture without compromising structure or flavor.
Create the Dry Flour Blend
In a medium bowl, whisk together the 2 cups almond flour and 0.5 cup oat flour until completely homogeneous. The almond flour should be finely ground—any gritty bits will disrupt the delicate crumb structure. I like to sift this mixture through a fine-mesh sieve to eliminate any potential clumps, which ensures even distribution when we mix with the wet ingredients.
Add the 2 tablespoons cornstarch and 0.5 teaspoon fine sea salt to the flour blend. The cornstarch acts as a structural stabilizer, compensating for the absence of gluten while maintaining that signature shortbread crunch. Use a whisk to distribute these dry ingredients evenly throughout the almond-oat flour mixture, breaking up any remaining lumps.
Cut in the Cold Butter
Place the bowl with the dry ingredients in the freezer for 5 minutes while you prepare the butter. This chilling step is crucial—it prevents the butter from melting prematurely during mixing. Using a pastry cutter or two forks, cut the 1 cup cold, cubed unsalted butter into the flour mixture until the texture resembles coarse sand with pea-sized butter pieces remaining.
Work quickly but deliberately—you want to maintain that cold butter temperature. If the mixture starts to look shaggy or the butter begins to melt, return the bowl to the freezer for another 2-3 minutes before continuing. The goal is to create maximum surface area for the butter to coat the flour without fully incorporating.
Add Sugar and Aromatics
In a separate small bowl, combine the 0.25 cup granulated sugar, 1 teaspoon pure vanilla extract, and 1 teaspoon lemon zest. The sugar should be superfine if possible—it dissolves more evenly and creates a smoother texture. Mix these ingredients thoroughly to create a cohesive aromatic base.
Using a wooden spoon or silicone spatula, gently fold this sugar mixture into the butter-flour blend. Be careful not to overmix—just until the sugar is evenly distributed and the dough begins to come together. The lemon zest will brighten the flavor profile while the vanilla adds depth, but don't overdo it; these are supporting characters in this recipe.
Form and Chill the Dough
Turn the dough out onto a clean work surface and gently press it together into a cohesive mass. If it feels too dry, add 1-2 teaspoons of ice water to help bind it. The dough should hold together when pressed but still feel slightly crumbly—this is normal for gluten-free shortbread. Divide the dough into two equal discs, flatten slightly, and wrap each in plastic wrap.
Refrigerate the dough for at least 1 hour or up to 24 hours. This resting period is essential for several reasons: it allows the flour to fully hydrate, prevents excessive spreading during baking, and gives the gluten-free structure time to stabilize. The longer it chills, the better the final texture will be.
Roll, Cut, and Bake for Perfect Texture
Preheat your oven to 325°F and line two baking sheets with parchment paper. Remove one disc of chilled dough and roll it out between two sheets of parchment paper to ¼-inch thickness. The paper prevents sticking and helps maintain even thickness. Use a 2½-inch round cutter to cut out cookies, pressing straight down without twisting—this ensures clean edges and prevents the dough from expanding.
Transfer the cut cookies to the prepared baking sheets, spacing them 1 inch apart to allow for spreading. Bake for 12-15 minutes until the edges are just beginning to turn golden—they'll continue baking on the hot sheet after removal. The centers should still look slightly underdone when you take them out; they'll firm up as they cool.
Let the cookies cool on the baking sheet for 10 minutes before transferring to a wire rack. This brief resting period prevents them from cracking as they cool completely. The final texture should be firm yet tender with that characteristic sandpaper crunch—achieved through the precise balance of almond flour, cornstarch, and proper baking technique.
Pro Tips For Making Wheat Free Shortbread Cookie
- Chill the Dough Properly: I learned this the hard way—rolling out almond flour dough at room temperature is a disaster. Wrap the dough in plastic and refrigerate for at least 30 minutes (or up to 24 hours if you’re planning ahead). The cold butter stays firm, and the oat flour binds better, so your cutouts hold shape instead of crumbling like sad little pancakes.
- Toast the Oat Flour: Skip the raw oat flour—it adds a weird, slightly bitter edge to the cookies. Pulse plain oats in a food processor until they’re fine flour, then toast them in a dry pan over medium heat for 3–5 minutes, stirring constantly. The nutty aroma deepens, and the texture stays crisp instead of gummy. (Yes, even if you’re impatient like me.)
- Press, Don’t Roll: Almond flour dough is stubborn. Instead of trying to roll it out like pie crust, press it gently between parchment paper with your hands or a glass until it’s about ¼-inch thick—just enough to keep the edges from burning while the centers stay tender. Overworking it turns the cookies dense, and under-pressing leads to uneven baking.
- Use Cold Butter, Twice: First, grate or cube the unsalted butter and freeze it for 10 minutes before mixing—this prevents the dough from getting greasy. Then, after shaping the cookies, pop them in the freezer for 10–15 minutes before baking. The cold butter creates those signature flaky layers, and the cookies won’t spread into sad, flat puddles. (Your future self will thank you.)
Best sauces and condiments for wheat free shortbread cookie
Classic Jam Pairings
These wheat-free shortbread cookies pair beautifully with raspberry jam or blackberry jam—their tartness cuts through the buttery richness perfectly. I like to spread ½ teaspoon of jam on the center of each cookie before serving.
For a festive touch, use orange marmalade during the holidays, as the citrus notes complement the lemon zest in the dough. 🍓
Cream Cheese Spread
Whip up a simple cream cheese spread by mixing 4 oz cream cheese with 1 tablespoon honey and a pinch of cardamom. Spread a thin layer on the cookies for a sweet-savory contrast.
This works especially well with the vanilla-infused shortbread. Store the spread in an airtight container in the fridge for up to 5 days.
Chocolate Drizzle
For a decadent finish, melt 2 oz dark chocolate (70% cocoa) with 1 teaspoon coconut oil over a double boiler. Drizzle over cooled cookies and sprinkle with flaky sea salt for a sophisticated touch.
I recommend Ghirardelli 70% dark chocolate for the best flavor. The chocolate enhances the buttery notes while adding a rich contrast. 🍫
Citrus Glaze
Create a bright citrus glaze by mixing ½ cup powdered sugar, 1 tablespoon lemon juice, and 1 teaspoon orange zest. Drizzle over the cookies while still warm for a glossy finish.
This glaze pairs especially well with the lemon zest in the dough, amplifying its citrusy brightness. Store any leftover glaze in a small jar for up to 3 days.
Nut Butter Swirl
For a protein-packed twist, spread almond butter or cashew butter on half of each cookie before pairing with another half. The nutty flavor complements the almond flour base beautifully. I recommend Justin’s Classic Almond Butter for its smooth texture. This combination adds a satisfying crunch and extra flavor depth. 🌰
Spiced Honey Dip
Heat ¼ cup honey with ½ teaspoon cinnamon and ¼ teaspoon ginger until warm. Drizzle over cookies or serve on the side for dipping. This spiced honey adds warmth and balances the buttery sweetness.
Store any leftover dip in a small jar in the fridge for up to 1 week.

Frequently asked questions
Why does this recipe use both almond flour and oat flour?
The combination creates the perfect texture—almond flour delivers that signature sandpaper crunch while oat flour adds structure and tenderness. The oat flour also helps mimic gluten's binding properties without compromising the gluten-free nature. Using just almond flour would make the cookies too crumbly.
Can I make these cookies without a round cutter?
Use a 2½-inch glass or metal round if you don't have a cutter. For rustic shapes, try a knife to cut irregular squares or rectangles. Just press straight down without twisting to maintain clean edges. Parchment paper makes this much easier for beginners.
What if my dough cracks when baking?
Cracking usually happens when cookies cool too quickly. Let them rest on the baking sheet for 10-15 minutes before transferring to a rack. Also ensure your oven isn't too hot—325°F is ideal. If cracks appear, they're still delicious but may need a quick reheat to restore crispness.
How do I store these cookies for maximum freshness?
Keep them in an airtight container at room temperature for up to 7 days. For longer storage, freeze the baked cookies (not dough) for up to 3 months. Thaw at room temperature for 1 hour before enjoying. The texture stays crisp best when stored properly.
Can I add chocolate chips to this recipe?
Yes, but use dark chocolate chunks (60% cocoa or higher) instead of milk chocolate—they won't melt as quickly. Add ½ cup to the dough after mixing the wet ingredients. For best results, chill the dough an extra 30 minutes to prevent spreading. The chocolate adds richness without overpowering the buttery flavor.
