For a Christmas biscuit plate, choose shortbread explicitly labelled sugar-free and check its ingredients and allergens; a gluten-free or milk-free label does not answer the sugar question. Gullon Sugar Free Shortbread is a ready-made option containing wheat and the sweeteners maltitol and isomalt, but a finished biscuit is not a like-for-like replacement for sugar in homemade shortbread dough. If you plan to bake, use a recipe developed for the sweetener you intend to use.
Who is choosing the shortbread?
Christmas hosts looking for sugar-free biscuits
If you are putting together a biscuit plate, hamper or tea-time spread, an explicit sugar-free claim matters more than a general festive or free-from description. Check the ingredients as well as the front of the pack.
Shoppers considering carbohydrate and portion size
A sugar-free label does not describe the whole biscuit. Diabetes UK notes that polyol sweeteners contain carbohydrate and calories, so check the nutrition panel and serving size rather than treating the label as a guide to how much to serve.
Bakers serving guests with allergen requirements
Sugar-free and allergen-free are separate requirements. The Gullon shortbread lists wheat; its manufacturer and UK retailer also give milk- and soya-related information. Check the current pack before serving it or adding it to a dessert.
What should you check before buying?
Decide whether you need finished biscuits for serving or a recipe for baking dough, then check the sugar claim and any dietary requirements separately.
| Priority | What to check | Your needs |
| Sugar claim |
Look for an explicit sugar-free claim. Read sugars per 100 g and the ingredients; a free-from label may refer to gluten or milk instead. |
I need sugar-free biscuits, not simply biscuits made without a particular allergen. Tesco and Sainsbury's both list sugar in the free-from shortbread described on their product pages. |
| Serving or baking |
Check whether the item is a finished biscuit or a sweetener intended for a particular recipe. For homemade dough, follow a recipe developed for the chosen sweetener. |
For a biscuit plate, I want a ready-made shortbread. If I am making dough, I need a recipe rather than assuming packaged biscuits can replace sugar. |
| Sweeteners and nutrition |
Read the sweetener ingredients, carbohydrate information, calories and serving size. Gullon Sugar Free Shortbread lists maltitol and isomalt. |
I want to know what sweetens the biscuit and how the portion fits the food I am serving. Diabetes UK notes that polyols contain carbohydrate and calories. |
| Allergens |
Check the current pack for declared ingredients and precautionary statements. Do not infer gluten-, milk- or soya-free status from a sugar-free claim. |
I am serving someone who needs to avoid a particular ingredient, so I must check that requirement independently before offering them the biscuits. |
What can cause a mix-up?

Reading ‘free from’ as ‘sugar-free’
Free-from wording may describe allergens rather than sugar. Tesco lists 29.9 g sugars per 100 g for its Free From Shortbread, while Sainsbury's lists 23.5 g per 100 g for its milk- and gluten-free shortbread.
Check for a sugar-free claim and read the sugars figure and ingredients. If an allergen matters too, check that separately on the current pack.
-
Assuming sugar-free means carbohydrate-free
Gullon Sugar Free Shortbread uses maltitol and isomalt. Diabetes UK explains that these polyol sweeteners contain carbohydrate and calories; sugar-free does not mean the biscuits can be treated as unrestricted portions.
Read the nutrition information and serving size. Anyone making diabetes-related dietary decisions, particularly involving insulin, should seek individual advice from their healthcare team.
-
Missing an allergen on a sugar-free pack
Gullon lists wheat flour. Its manufacturer says the shortbread may contain milk and soya beans, while the UK retailer listing includes milk proteins and warns of possible soya traces.
Use the ingredient and allergen statements on the physical pack when deciding whether to serve it to a guest.
-
Treating finished biscuits as a sugar substitute
A ready-to-eat shortbread biscuit cannot simply be measured into dough in place of sugar. Its product information does not establish how a homemade shortbread recipe would bake with a different sweetener.
For homemade shortbread, choose a recipe designed for the sweetener you plan to use and try a small batch before making biscuits for an event.
Which product lines are relevant?
These examples show why a sugar-free claim and an allergen-focused free-from claim need separate checks; they do not describe every biscuit made by each brand.
Gullon
Gullon ZERO Sugar Free Shortbread is a packaged, ready-made biscuit described as sugar-free by the manufacturer and listed as a 330 g product by Continental Food Store.
- Its ingredients list identifies maltitol and isomalt as sweeteners.
- It contains wheat; check the current pack for milk and soya information. It is not a baking-ingredient replacement.
Tesco Free From
Tesco Free From Shortbread illustrates an allergen-focused option that should not be mistaken for sugar-free shortbread.
- The listed recipe uses cornflour, rice flour and soya flour.
- Tesco also lists butter and sugar, with 29.9 g sugars per 100 g on its product page.
Sainsbury's Free From
Sainsbury's describes this shortbread as milk- and gluten-free, addressing a different requirement from sugar-free shortbread.
- The stated milk- and gluten-free claims help identify the product's intended free-from route.
- Sugar appears in its ingredients, and Sainsbury's lists 23.5 g sugars per 100 g.
Joybuy biscuit option
This Joybuy option is a ready-made sugar-free digestive biscuit, not shortbread. Consider it for serving only if a digestive suits your plans; do not use its listing as a shortbread recipe or a guide to replacing sugar in dough.

Gullon Zero Sugar Free Original Digestives 400g
A ready-made digestive biscuit for a serving plate, rather than the shortbread specified in this buying question. Its listed nutrition information states less than 0.5 g sugars per 100 g, and its ingredients identify isomalt and maltitol. It contains wheat and may contain milk and soya; check the pack before serving anyone with an allergen requirement. The product information also warns that excessive consumption may produce a laxative effect.

Questions about serving and baking
How do I identify sugar-free shortbread?
Look for an explicit sugar-free claim, then read the sugars figure and ingredients on the current pack. Gluten-free, milk-free and other free-from wording describes separate requirements; it does not establish that a biscuit is sugar-free.
Will gluten-free or milk-free shortbread meet a sugar-free requirement?
Not on the strength of those claims alone. Tesco lists 29.9 g sugars per 100 g for its Free From Shortbread, and Sainsbury's lists 23.5 g per 100 g for its milk- and gluten-free shortbread. Check any sugar requirement independently on the product you intend to buy.
Is sugar-free shortbread automatically suitable for someone managing diabetes?
No: the sugar-free label does not describe its total carbohydrate, calories or an appropriate portion. Gullon Sugar Free Shortbread uses the polyols maltitol and isomalt; Diabetes UK notes that polyols contain carbohydrate and calories and recommends individual healthcare advice for people adjusting insulin.
What should I check before serving Gullon Sugar Free Shortbread to guests?
Read the physical pack's ingredient and allergen statements. Gullon lists wheat flour and warns of possible milk and soya exposure; the UK retailer listing also includes milk proteins. Check those details against each guest's requirements before serving the biscuits.
