Gluten free shortbread cookies are the simplest cookies with the fewest ingredients, so let's make the same base recipe into 5 different varieties: plain, glazed lemon, mocha, toffee caramel and berry chip. Or mix and match for the most beautiful cookie plate ever!
This foolproof recipe for gluten free shortbread cookies quickly and easily makes 5 varieties: plain, glazed lemon, mocha, toffee caramel and berry chip. The simplest recipes really are the best!
Why this recipe works
For each of these 5 recipes, we start off the same, with a gluten free shortbread cookies mix. And since shortbread cookies are pretty much the absolute simplest cookies around, that mix is dead simple: some flours, sugar, and salt.
The “plain” recipe below is really the only one you need. Use the proportions for each variety to make them your own, for each recipe of shortbread cookie dry mix, you'll need 8 tablespoons of unsalted butter.
Beyond that, add 1/3 cup of mix-ins (like chopped dried fruit, mini chocolate chips, toffee bits or any other tiny mix-ins). Drizzle with chocolate, top with cinnamon sugar, sugar-in-the-raw, or mocha sugar. You get the idea!
Gluten free shortbread cookies: the basic method
The basic recipe can be used with the simple addition of unsalted butter and a little water, as needed, to make plain shortbread cookies. Just mix everything together, knead and shape the cookie dough into a rectangle about 1 1/2-inches thick, wrap it tightly and refrigerate until firm.
Then, slice the cookies by cross-section, place on a baking sheet, and bake for less than 10 minutes. You can even make and shape the raw cookie dough and store it for weeks in the refrigerator before slicing and baking.
If you refrigerate the dough for longer like that, it will become too stiff to slice. Just allow it to sit at room temperature until you can slice it easily, and proceed with the recipe as written.
Expert tips
Measuring out ingredients
If you plan to make all 5 kinds of shortbread cookies, multiply all the shortbread cookie mix ingredients by 5, and whisk to combine well. You can also multiply the basic plain mix by 2.5 (for a total of 863 grams), and make 1/2 recipe for each variety.
If you're making a full recipe of any variety, measure out 345 grams of the well-combined dry mix for each recipe. If you're making a half recipe, measure out 173 grams.
Then, proceed with the instructions as written for each, dividing all the remaining ingredients by half if you're making a half recipe of each (or any) variety. You'll be amazed at how quickly you can make a bunch of cookie flavors. Talk about impressive!
Working with the raw dough
Because there isn't a lot of moisture in this gluten free shortbread cookies recipe, it will seem like your dough isn't coming together, but it will! Just keep mixing until it forms a soft dough, but don't over-mix; otherwise, your finished product may come out super delicate and crumbly.
When it's ready, roll out your dough until it's about ⅜-inch thick. You can do this over a piece of parchment paper that's been lightly dusted with gf flour.
When you reach the right thickness, cut the dough using a knife or pizza cutter for square or rectangular cookies, or cookie cutters for other shapes.
If you use cookie cutters, you may end up with a lot of scraps. Don't you dare throw them away! Because there's no gluten that can toughen up with continued handling, you can re-roll your dough over and over again until you've used it all.
Mocha cookies
Mocha cookies are made with the addition of some cocoa powder and instant espresso powder to the basic shortbread dough. The real magic happens when you dip each slice of cookie dough in a coating of cocoa powder and granulated sugar.
Berry chip cookies
For the berry chocolate chip cookies, just add dried berries and mini chocolate chips to the dry mix. I like dried cranberries and miniature chocolate chips, but you could add all mini chips and make them chocolate chip.
You could also try chopped nuts (walnuts, pecans, or pistachios are all great soft nuts) in place of dried berries. The chocolate drizzle adds a bit of extra chocolate flavor and lots of charm, but isn't strictly necessary.
Toffee caramel cookies
Toffee caramel cookies are by far the fanciest, since they are made with toffee bits mixed into the basic dough, then dipped in chocolate and drizzled with caramel.
Glazed lemon cookies
Glazed lemon gluten free shortbread is made fresh and lemony with lemon juice lemon zest, then topped with a simple lemon glaze. I used to add a bit of “True Lemon,” which is a granulated lemon “seasoning blend.” I've swapped that out for lemon juice, instead.
Not everyone has or can find True Lemon, but if you do have it, try adding about a teaspoonful to the recipe as written for a ton of lemon flavor. There are other True flavors, and they're all worth trying!
Key ingredients
Choosing the right gluten free flour blend
I must stress that, as always, the all purpose gluten free flour blend that you use matters—a lot. It always matters and it matters even more in an incredibly simple recipe like this.
Each time a blog recipe calls for an all purpose gluten free flour, I link to the page on the blog that has all the details about which blends I caution against, and which are appropriate. If you only have a blend like Bob's Red Mill, which I warn against strongly, or Namaste, which I also caution against, I cannot promise results.
In fact, if you have success with something like Bob's Red Mill flour blend, I can't promise repeat results. The blend is inconsistent, which is a large part of my concerns with it.
Using a poorly balanced flour blend or one that has gritty rice flour, then promising that you followed the recipe “to a T” and blaming the recipe for the failure is like using someone else's recipe and looking to this site to fix it.
Dipping in chocolate
I love coating my gf shortbread cookies in chocolate, whether that involves dipping, drizzling, or a combo of the two.
I find that the best way to work with chocolate is to use semi-sweet mini chips. Place them in a microwave-safe bowl and melt them 20 seconds at a time, stirring after each zap, until they reach the right consistency. If you're making an extra-large batch of cookies, you might find a double boiler to be more convenient.
When the melted chocolate is ready, simply dip a cooled cookie into it. You can dip a third of the cookie, half of the cookie, or the whole top or bottom. Be sure to tap off any extra chocolate, and then place the cookie on a parchment-paper-lined baking sheet so that the chocolate can firm back up.
Ingredient substitutions
The two main additional allergens in the basic gluten free shortbread cookie recipe are dairy and cornstarch. For the mix-ins, if you're avoiding other allergens, use your best judgment.
Dairy free
In place of butter, try using vegan butter. Melt and Miyoko's Kitchen brand are my favorites. Avoid Earth Balance, which has too much moisture, since the cookies won't hold their shape. Plus, double-check any inclusions like chocolate chips and toffee bits to be sure you're using dairy free ingredients.
Cornstarch
In place of cornstarch, try using arrowroot. If you're already using a higher starch flour blend, like Cup4Cup or my mock Cup4Cup blend, omit the cornstarch and use another 1/4 cup (35 g) Cup4Cup in addition to the original 1 1/2 cups (210 g).
Storage instructions
Because these gluten free shortbread biscuits are so tender and melt-in-your-mouth delicious, they don't last long in my home. But when I do need to put them away, I just store them in a sealed glass container on the kitchen counter. Assuming they last that long, they'll be good for a week there. Freezing baked cookies is definitely the way to go (but freezing them unfrosted is best).
Just wrap them up tightly in a freezer-safe container, and they'll stay fresh for up to three months. When you're ready for a snack, just let your gluten free cookie (or cookies) defrost on the counter.
Troubleshooting
Poke holes in the cookies
Poking holes in your raw gf shortbread cookies can offer steam a way to escape during the baking process. Personally, I find that the cookies come out just fine with or without holes, so feel free to experiment to see what you like.
Crumbly cookies
There are two primary reasons this gluten free shortbread cookies recipe has resulted in crumbly cookies.
The first involves your gluten free flour. If it's missing xanthan gum, it's lacking the holding power these cookies need to stay together.
The second involves your mixing method. If you over-mix the dough, it might create a more delicate cookie. To avoid this issue, only mix your ingredients until they've formed a soft dough; there's no need to keep mixing after that.
Cookies that spread too much
There's a lot of butter in these gf shortbread cookies, and when it heats up, it's going to spread. That's why it's essential that you chill your dough before slicing. It makes slicing easier, but it also helps the dough retain its shape as it bakes.
Make ahead
Yes, you can make your gluten free shortbread dough ahead of time and store it in the fridge for about a day. Don't go too much beyond that though as the dough's consistency will change and the cookies won't turn out the same.
Likewise, I find that this dough isn't a great contender for freezing. The baked cookies freeze wonderfully, but the dough doesn't quite hold up.

- Add more lemon juice by the 1/4-teaspoon, mixing to combine well, until the glaze falls off the spoon slowly, in a thickly pourable glaze. Add lemon juice very slowly, as it is much easier to thin, than to thicken, the glaze.
- If you do thin the glaze too much, add more confectioners’ sugar a teaspoon at a time to thicken it. Dip the tops of the cooled cookies in the glaze and place on a flat surface to sit until the glaze is set.

I made the plain ones today using King Arthur’s GF blend (I know, not the best, but I am at the beach, and it is all the grocery store here had — at home I use Better Batter). I had to add water to bring the dough together. Then after baking, I drizzled them with honey and sprinkled with cinnamon for a little faux sopapilla flavor. Yum! Can’t wait to make them at home using a better flour, but even so these are great!
Thank you for sharing that, Christie, and I had to laugh about what you said about the flour blend you used. Thank you for hearing me out, and I’m glad you were satisfied with the results and know the cookies can be even better!
I always loved your recipe for chocolate caramel shortbread. I can’t find it now. Is it no longer available?
That recipe is no longer available on the blog, but you can find a printable recipe here. Please print it off and keep it somewhere safe!
Hi Nicole, I am giving these cookies a 5 star rating as the flavour is really great, and made following your recipe are probably delightful ! However I wanted to test with alternative sweetner even though you advised against it. It was an experiment. So those of you wishing to make with alternative sweetner, don’t waste your ingredients. Go find a keto or diabetic recipe for shortbread, as this did not work with alternative sweetner. The texture is not like shortbread at all, using the alternative sweetner. Hope this helps those wondering about it. Merry Christmas from Canada ??
Thank you for understanding that making such a large change as that to such a simple recipe meant that you really didn’t make my recipe, Lola! I agree that you should find a recipe developed to be made with a sugar alternative.
I made this today. I had to use 3 teaspoons of water to get the dough to come together. I also used European Butter so maybe that’s why I needed more water. I rolled the dough a bit less than 1/2” & 4” wide and cut into sticks. I’m going to dip the ends in white chocolate & semi sweet chocolate. I made a second batch and used my embossed roller and cut out circles with a 2 1/4” biscuit cutter. These are a delicious simple cookie that can be decorated in many way. I love them plain.
Would these work if I subbed tapioca starch for the corn starch? Corn allergy
Hi, Wendy, I’d use arrowroot, not tapioca, which has a stretchy quality we don’t want extra of here.
P.S. One more hint. Add light corn syrup about 2 t to 1 c. Powdered sugar. The glaze it makes is shiny and crackly. You can stack these cookies after it is all dry (20 min.).
It also takes gel color brightly!
