Sugar-Free Chai Spiced Shortbread is a buttery, slice-and-bake cookie built on cinnamon, cardamom, ginger and clove, sweetened with a powdered sugar substitute instead of sugar, much like these sugar-free pistachio rosewater cookies. It bakes at 163 C / 325 F for 14 to 16 minutes, until the edges turn light gold and the centers stay pale.
I started making this batch after running low on sugar mid-holiday baking. Turns out the chai spices carry so much flavor that the sweetener barely matters. The dough behaves just like classic shortbread, rich and a little sandy, until it hits the oven and turns crisp at the edges.
These cookies keep their shape well if you chill the dough logs first. Skip that step and they spread thin, with blurred edges instead of a clean round.
They’re soft to bite, faintly sweet, and warm with spice. Good with coffee, better with a mug of actual chai.

- Real chai spices, cinnamon, cardamom, ginger and clove in every bite
- Dough logs freeze well for cookies on short notice
Ingredient Notes
- unsalted butter: Use softened, not melted, butter for a light base. Salted butter works too if you cut the added salt to a pinch.
- powdered sugar substitute: I use a powdered erythritol or monk fruit blend so the dough stays tender instead of grainy. Granular sweetener works but leaves a slightly sandy bite.
- vanilla extract: Adds warmth against the chai spices. Use pure extract if you have it.
- all-purpose flour: Keeps the dough sturdy enough to slice clean. A 1:1 gluten-free blend works if you need it gluten free.
- cornstarch: Cuts the gluten just enough to keep the shortbread tender instead of tough.
- salt: Balances the sweetness and makes the spices taste sharper.
- ground cinnamon: The backbone of the chai blend. Ceylon cinnamon gives a milder, brighter note than cassia.
- ground cardamom: Gives the shortbread its signature chai smell. Don’t skip it even if the jar’s pricey.
- ground ginger: Adds a little heat at the back of the throat, classic chai flavor.
- ground cloves: Strong stuff. A little goes far, stick to the amount listed or the cookies taste medicinal.
Easy Baked Sugar-Free Chai Spiced Shortbread Cookies
Ingredients
Method
- In a large bowl, beat the softened butter and powdered sweetener with a hand mixer on medium speed for 2 to 3 minutes, until light and fluffy.
- Add the vanilla extract and mix until combined.
- In a separate bowl, whisk together the flour, cornstarch, salt, cinnamon, cardamom, ginger and cloves.
- Add the dry ingredients to the butter mixture in two batches, mixing on low speed until a soft dough forms with no dry streaks of flour left.
- Divide the dough in half. Roll each half into a log about 5 cm / 2 inches wide on a sheet of plastic wrap, twisting the ends to seal.
- Chill the logs in the fridge for at least 60 minutes, until firm enough to slice cleanly. Soft dough will smear instead of cutting into neat rounds.
- Heat the oven to 163 C / 325 F and line a sheet pan 33 x 46 cm / 13 x 18 inch with parchment paper.
- Unwrap the chilled logs and slice into rounds about 1 cm / 1/3 inch thick with a sharp knife. Arrange on the sheet pan, spacing them 2.5 cm / 1 inch apart.
- Bake for 14 to 16 minutes, until the edges turn light golden and the centers still look pale and matte.
- Cool the cookies on the pan for 5 minutes, then transfer to a wire rack to cool completely before serving or storing.
Notes
- Powdered sweetener blends into fat more evenly than granular, use a food processor to grind it fine if yours is coarse.
- Dough logs must feel firm, not just cool, before slicing.
- Bake one test cookie first if you’re unsure about your oven’s true temperature.
- Cloves are strong, measure with a proper 1/4 tsp rather than eyeballing.
Tips for Success
- Chill the dough logs for a full 60 minutes before slicing, or the rounds will smear instead of cutting clean.
- Roll the logs on a flat surface and rotate as you go, so they stay round instead of flattening on one side.
- Use a sharp, thin knife and slice in one smooth motion so the spice flecks don’t smear across the cut edge.
- Rotate the sheet pan halfway through baking if your oven runs hot on one side.
- Store cooled cookies in an airtight container right away, warm cookies trap steam and turn soft by the next day.
Variations
- Roll the sliced cookies in a cinnamon and sweetener mix before baking for a lightly crackled sugar-free coating.
- Dip cooled cookies halfway in melted sugar-free dark chocolate and let set on parchment for a two-tone treat.
- Swap the ground cloves for a pinch of black pepper and star anise for a deeper, more savory chai profile.
Storage and Reheating
Sugar-Free Chai Spiced Shortbread keeps well at room temperature. Store cooled cookies in an airtight container for 5 to 6 days, layering parchment between them so they don’t stick.
Freeze the unbaked dough logs wrapped tightly in plastic for up to 3 months, then slice and bake straight from frozen, adding 2 to 3 extra minutes. Baked cookies also freeze in an airtight container for up to 2 months.
No reheating is needed, these are meant to be eaten at room temperature. If you want that fresh-baked smell back, a quick 5 minutes in a 150 C / 300 F oven crisps the edges again.
Serving Suggestions
Chai spiced shortbread goes best with the tea it’s named for. Brew a strong cup of chai and let a cookie sit on the saucer while you drink it.
Coffee with a splash of milk works just as well, and the spices hold up next to a bowl of stewed pears or a slice of sugar-free blackberry almond galette for a fall dessert plate.
These also pack well for gifting. Stack them in a jar or tin with parchment between layers and they travel without breaking.
FAQ
Why did my chai spiced shortbread spread instead of holding a clean edge?
Your dough was too warm when it hit the oven. Butter that’s over-softened or logs that skipped the fridge won’t hold their round shape and spread into thin, blurry edges. Chill the logs for a full 60 minutes, and if your kitchen runs warm, pop the sliced rounds back in the fridge for 10 minutes before baking.
Can I use a different sugar substitute, like allulose, instead of erythritol in this shortbread?
Yes, allulose works and actually browns a bit faster than erythritol, so watch the last few minutes of baking. Monk fruit blends that measure like sugar work too, the same sweetener used in this sugar-free mango coconut pudding. Avoid liquid sweeteners like stevia drops, they’ll throw off the dough’s texture and the cookies won’t hold together.
Can I freeze the shortbread dough logs before baking them?
Yes, wrap the logs tightly in plastic and freeze for up to 3 months. Slice the frozen dough straight from the freezer, adding 2 to 3 extra minutes to the bake time. Baked cookies also freeze well in an airtight container for up to 2 months.
What pairs well with chai spiced shortbread for an afternoon snack?
Chai tea is the obvious match, since the same spices show up in both. Coffee with a splash of milk works too, and the cookies hold up well next to a bowl of stewed pears or spiced applesauce for a fall dessert plate.
Is this sugar-free chai spiced shortbread keto friendly?
Not as written, since it uses regular all-purpose flour and cornstarch, both higher in carbs. It’s sugar-free but each cookie still has about 10 g of carbs. For a keto version, swap in a 1:1 almond and coconut flour blend, though the texture turns more crumbly.
What makes chai spiced shortbread different from classic Scottish shortbread?
The base dough is nearly identical, butter, flour and a sweetener creamed together. The difference is the chai spice blend, cinnamon, cardamom, ginger and clove, folded into the dry ingredients, which classic shortbread skips entirely in favor of plain vanilla or just butter flavor.
