Buttery Gluten Free Shortbread Recipe

I’ve perfected a buttery, homemade gluten-free shortbread that’s quick to make and sings when drizzled or dipped in chocolate.

I adore these buttery gluten free shortbread cookies because they taste like unsalted butter turned into a cookie. I can’t resist the crumb that flakes apart under your teeth, leaving rich, clean butter flavor and a whisper of sweetness.

But the best part is how they take dark or semisweet chocolate, whether I drizzle or dunk. I love that they feel fancy without pretense, perfect for when I want something indulgent but simple.

Pure, honest ingredients. Little bites that make ordinary moments feel deliberately delicious and somehow undeniably necessary.

I reach for them whenever I need a real, focused treat.

Ingredients

• Unsalted butter: Rich, silky fat that makes the shortbread melt in your mouth.
• Powdered sugar: Gives that fine, not-gritty sweetness and a tender crumb.
• Cornstarch or tapioca starch: Basically the secret for a delicate, crumbly texture.
• Gluten free all purpose flour: The base that holds everything together without gluten.
• Fine sea salt: Pops the sweetness and makes the butter taste more buttery.
• Vanilla extract: Adds warm, cozy aroma that makes it taste homemade, not bland.
• Dark or semisweet chocolate: For dipping or drizzling, adds bitter-sweet contrast and richness.
• Neutral oil: Plus a splash thins chocolate so it glosses and sets smoothly.

Ingredient Quantities

• 1 cup (2 sticks) unsalted butter, softened
• 1/2 cup powdered sugar, sifted
• 1/2 cup cornstarch (or tapioca starch), for tender crumb
• 2 cups gluten free all purpose flour, measure and level
• 1/4 teaspoon fine sea salt
• 1 teaspoon vanilla extract
• 4 ounces dark or semisweet chocolate, for drizzling or dipping
• 1 teaspoon neutral oil (like vegetable or light olive), to thin chocolate if needed

How to Make this

1. Preheat oven to 325°F (163°C). Line a baking sheet with parchment or silicone, or grease and line an 8 inch square pan if you want shortbread bars.

2. In a large bowl beat 1 cup (2 sticks) softened unsalted butter with 1/2 cup sifted powdered sugar until pale and fluffy, about 2 to 3 minutes; don’t overmix or it’ll get greasy.

3. Stir in 1 teaspoon vanilla extract and 1/4 teaspoon fine sea salt until combined.

4. In a separate bowl whisk together 1/2 cup cornstarch (or tapioca starch) and 2 cups gluten free all purpose flour, measure and level the flour first so the texture is right.

5. Fold the dry mix into the butter mixture with a spatula until a soft dough forms; it will be slightly crumbly but should hold when pressed. If it’s too dry add a teaspoon of milk or cream, one at a time.

6. For rounds: turn dough onto a sheet of parchment, press into a 1/2 inch thick rectangle, top with another parchment and roll to even thickness, then chill 20 to 30 minutes. For bars: press dough evenly into the prepared pan and chill 15 to 20 minutes to reduce spreading.

7. If making rounds cut into shapes with a cookie cutter or knife, place on prepared sheet about 1/2 inch apart. Dock cookies with a fork if you want that classic look and more even baking.

8. Bake at 325°F for 12 to 18 minutes for cookies (less for small cutters, more for larger) or 20 to 28 minutes for bars, until edges are just set and bottoms are very lightly golden. Let cool on the sheet for 5 minutes, then transfer to a rack to cool completely.

9. Melt 4 ounces dark or semisweet chocolate gently in a microwave in 20 second bursts stirring between each, or use a double boiler. Stir in 1 teaspoon neutral oil if you need the chocolate thinner for dipping or drizzling. Dip or drizzle cooled shortbread, let the chocolate set at room temp or chill briefly.

10. Store in an airtight container at room temperature for up to 5 days or freeze for longer. Pro tip: chilling the formed dough makes cleaner edges and less spreading, and sifting powdered sugar keeps the crumb super tender.

Equipment Needed

1. Oven (preheated to 325°F / 163°C)
2. Baking sheet lined with parchment or silicone, or an 8 inch square baking pan if you want bars
3. Large mixing bowls (one for butter, one for dry ingredients)
4. Electric mixer or sturdy whisk and a wooden spoon (don’t overmix)
5. Rubber spatula for folding and scraping the bowl
6. Rolling pin and extra parchment for rolling and chilling rounds (or just press into pan for bars)
7. Cookie cutters or a sharp knife and a fork for docking
8. Microwave safe bowl or small saucepan and heatproof bowl for melting chocolate, plus a cooling rack for finished cookies

Buttery Gluten Free Shortbread Recipe Substitutions and Variations

• Butter: swap with equal amount vegan stick butter for a dairy free result, or use 3/4 cup solid coconut oil (chill dough a bit longer if warm).
• Cornstarch: use tapioca starch or potato starch 1:1 for the same tender crumb; arrowroot works too but can make dough a tad stickier.
• Gluten free all purpose flour: if you dont need GF, plain all purpose flour works 1:1; or try a homemade blend of rice flour + tapioca + potato starch (follow your usual ratio).
• Chocolate for drizzling: substitute chocolate chips or chopped milk chocolate; to thin, use a teaspoon of butter instead of oil for extra shine and flavor.

Pro Tips

1. Chill the formed dough longer than you think, like 30 to 45 minutes if your kitchen is warm. It firms the butter so the cookies keep sharp edges and dont spread into sad blobs.

2. Use a light touch when mixing after adding the flour. Overworking makes the crumb tough, so fold just until it comes together, even if it looks a little shaggy.

3. Warm the chocolate slowly and add that teaspoon of neutral oil only if needed. Too hot chocolate will seize, so stop microwaving when a few glossy lumps remain and stir till smooth.

4. Measure the gluten free flour by spooning it into the cup and leveling, dont scoop with the cup. Too much flour dries these out fast, and cornstarch helps keep them tender so dont skip it.
