These gluten free brown sugar shortbread cookies are made with little more than butter, brown sugar and flour, hold their shape, and are anything but plain. They’re lightly sweet, and just a little bit tender but still crumbly like any proper shortbread must be.
Why brown sugar?
I’ve had a recipe for “basic” gluten free shortbread cookies made with granulated sugar on the blog since 2014. You can even take that basic shortbread dry mix and make it into 5 different varieties of shortbread.
That 5-in-1 recipe is a great way to fill out a cookie tray without making yourself crazy with a million different recipes. They’re pretty similar to the butter cookies recipe (made with egg yolks and more sugar) here on the blog, too.
I’ve even got a recipe for gluten free whipped shortbread cookies. That recipe is made with confectioner’s sugar and the cookies absolutely melt in your mouth. They’re amazing with a dollop of jam in the center, almost like a hybrid shortbread/thumbprint cookie.
Like any cookie recipe that has 3 or 4 ingredients, though, this recipe for brown sugar shortbread cookies is soooo similar, but in many ways a world apart. Using brown sugar as a sweetener adds a softness and a really mild tang from the molasses in the sugar.
How to make chocolate brown sugar shortbread
Unlike the 5-in-1 shortbread cookie recipe referred to above, this recipe for brown sugar shortbread doesn’t really need to be dressed up to taste great on its own. They’re simple, but have a pleasantly complex taste that allows them to stand on their own.
Since they tend to look a bit plain, though, I like to dip these cookies in a bit of chocolate or even drizzle them with some melted chocolate. That’s never really a bad idea if you’re looking to impress.
But as I was refining this recipe, I suspected that you could replace the cornstarch with an equal amount of unsweetened Dutch-processed cocoa powder and make pleasantly chocolate-flavored shortbread cookies. And I was right!
At first, I tried replacing half of the cornstarch with cocoa powder, but the cookies barely tasted like chocolate at all. And their color was almost gray.
You’ll need to replace all of the cornstarch with unsweetened cocoa powder. The reason for using Dutch-processed cocoa powder is that it’s a cocoa powder that has had its acidity balanced to neutral.
Natural unsweetened cocoa powder (like regular Hershey’s cocoa powder) is acidic and needs to be balanced with a bit of baking soda to avoid a sharp flavor. Since we don’t want these cookies to rise (that’s why we pierce them before baking!), it’s best to avoid baking soda.
If you only have natural cocoa powder and really want to make chocolate shortbread cookies, try using just 1/8 teaspoon baking soda along with 7 tablespoons (35 grams) cocoa powder in place of the cornstarch. The chocolate variety of these cookies will spread a bit more, though, because of the lack of cornstarch.
Ingredients and substitutions
These super simple gluten free cookies are already egg-free, too, as are all classic shortbread cookie recipes. They do have a few other potential allergens, though, so here are my best-educated guesses for how to make these cookies suit other dietary needs.
As always, the moment you make a change to the recipe as written, either in ingredients or method, I can no longer promise results. That is doubly true with a super simple recipe like this cookie recipe. But if you’re game for some experimenting, here’s how I recommend doing it.
Dairy-free: To replace the butter in this recipe, I’d recommend trying Melt brand vegan butter replacement. It is the closest to behaving like butter in baking that I’ve ever found.
If you can’t find Melt, though, try using half Earth Balance buttery sticks (which have way too much moisture) and half nonhydrogenated vegetable shortening (which has nearly no moisture). Omit the salt, though, as Earth Balance is super salty.
Corn-free: This recipe calls for cornstarch in addition to gluten free all purpose flour to add some lightness. If you’re using Cup4Cup gluten free flour blend, use 1 1/4 cups of Cup4Cup and omit the cornstarch, as Cup4Cup is already very high in cornstarch.
If you need to omit cornstarch altogether, you shouldn’t have trouble replacing it. Try arrowroot in its place or even potato starch. Either should work fine.
Sugar-free: Since this recipe is so, so simple, I really don’t recommend using an alternative sugar. But since there is only 1/3 cup of brown sugar, you could try using Swerve brand’s brown sugar alternative.
You may have to add a tiny bit of water, though, to the dough as Swerve tends to be drying. Add water by the drop (literally) because you can’t take it out—and if you add too much moisture, your cookies will spread.
HELLO! I’m Nicole! I make gluten-free food enjoyable & affordable. If they can make it with gluten, we can make it without. That’s a promise!

I’ve been looking for a good gluten-free substitute for Walker’s scottish style shortbread, as I fell in love with them on the trains in the UK. Would you say these or your classic Gluten Free Shortbread have a more British style to them?
Hi, Hannah, I think you’d prefer these brown sugar shortbread cookies, but I’m afraid I’m not 100% sure!
Followed the recipe and they turned out amazing! Thanks! 😊
I would like more gluten free recipes, bread, crackers etc
Hi, Linda, please have a look around! There are nearly 1000 free recipes here on the blog.
oohhhh these look delicious!! On my cookie list indeed!
How do you make the chocolate dip. What are the measurements.
Hi, Kathie, I just used chopped dark chocolate and melted it with a bit of virgin coconut oil (triple filtered has no coconut taste if that’s a concern). The general ratio for a glaze like this is 1 teaspoon (5 g) of virgin coconut oil for each 2 ounces of chopped chocolate.
I usually only have salted butter in fridge and use in all recipes, but maybe omit extra salt. Is there any advantages in using unsalted butter, ie does it alter the texture/taste//baking times etc. Thankyou as I’ve often wondered about this and never had the chance to test both options.
Hi, Raye,
I typically specify unsalted butter in my recipes because it allows me to control the amount of salt in a recipe. Salted butter has varying levels of salt, and often has too much. You can try using your salted butter and omitting the salt in this recipe, but I can’t promise that it won’t taste too salty. In the future, you might want to consider stocking unsalted butter as you can always add more salt, but can’t remove it. Hope that’s helpful!
Can you use ghee instead of butter?
No, you cannot use ghee in place of butter, sorry, Denise! Please see the ingredients and substitutions section for further information on substituting the butter.
What do you use for the chocolate dip/drizzle?
I just melted some dark chocolate with a touch of coconut oil so it doesn’t dry hard, Lisa.
Hi Nicole. I have been wanting to make a brown sugar shortbread for a long time but was not sure . I am excited to try this. Do you think this dough could be rolled into a log, refrigerated then sliced to bake? Only asking as the ones my aunt made (pre-celiac)that I loved were made this way. Thanks for all the wonderful recipes! I have all of your books, and always find inspiration.
Hi, Leann, I haven’t tried these as slice and bake, and generally prefer that method for butter cookies, not shortbread, as butter cookie dough is stiffer and easier to shape that way and slice. I think you’d have trouble maintaining the shape, I’m afraid, but it wouldn’t hurt the taste at all if you’d like to try. Thank you for the kind words, and your support! It means so much to me.
