Home bakers changing a biscuit recipe
If your aim is to change the sugar in the biscuits, look for a recipe written for your chosen baking sweetener rather than treating a confectionery mint as measured caster sugar.
Who is choosing?
Bakers serving mints separately
If the biscuit recipe stays as it is, a sugar-free mint can be a separate sweet to offer afterwards or put on the table. Its label describes the mint, not the biscuits.
Households checking ingredients
When sharing mints with guests, compare the exact pack for sweeteners, dairy and soya ingredients, gluten-related declarations and dietary suitability.
What should you check?
Decide whether the mint is for eating separately or whether you want to alter the dough. Then check the ingredients and directions for the product you will actually use.
| Priority | What to check | Your needs |
|---|---|---|
| Role in the recipe | Check whether the product is a ready-to-eat mint or a sweetener intended for baking. For a change to the dough, follow quantities in a recipe developed for that sweetener. | I want to change the biscuits themselves, rather than serve a different sweet alongside them. |
| Sweetener ingredients | Read the ingredient list: the mint products described by Tesco and Waitrose use different sweeteners, including sorbitol, xylitol, sucralose and isomalt. Check any consumption warning on the pack. | If the mints will be shared, I want to know which sweeteners are in the exact product. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU). |
| Dietary declarations | Check the current pack for dairy, soya and gluten-related declarations, as well as any vegan claim. Waitrose lists cream, butter and soya lecithin in Sulá Mint Humbugs. | Guests may have ingredient restrictions, so a front-of-pack sugar-free claim alone does not answer whether I can serve the mints to them. |
| Biscuit ingredients | Keep the mint label separate from the biscuit recipe. Tesco Real Food’s Christmas biscuits recipe, for example, specifies 115g golden caster sugar. | I may want a sugar-free mint after baking without changing what goes into the biscuits. |
Mistakes to avoid
-
Replacing recipe sugar with crushed mints
Ready-to-eat mints contain different sweeteners and other confectionery ingredients; a biscuit recipe that measures caster sugar does not establish an equivalent amount of crushed mints.
If changing the dough is the aim, use a recipe developed for a specified baking sweetener. Keep mints separate unless a recipe expressly calls for them.
-
Choosing by the sugar-free claim alone
The claim does not tell you which sweeteners or other ingredients a mint contains. For example, Waitrose lists dairy and soya ingredients in Sulá Mint Humbugs.
Read the ingredients and allergen declaration on the exact pack, particularly when serving someone with a dietary restriction.
-
Overlooking pack cautions
Tesco’s Smint listing and Waitrose’s Sulá Mint Humbugs listing warn that excessive consumption may produce laxative effects. Smint contains aspartame, which the NHS says is unsuitable for people with PKU.
Check the sweeteners and warnings before sharing mints, especially if PKU is relevant.
-
Applying the mint label to the biscuits
Serving a sugar-free mint does not change the ingredients in a conventional biscuit recipe.
Decide whether you are changing the bake or simply offering a separate mint, and check each product on its own terms.
Mint brands and product lines
These examples show why ingredient checks matter when choosing mints to serve with biscuits; they do not establish how the mints would perform in dough.
POLO
Tesco lists POLO Sugar Free as a pressed mint confectionery product containing sorbitol and mint oils.
- Tesco labels the listed product as having no sugar and as suitable for vegans.
- Its confectionery ingredients do not establish a caster-sugar substitution for biscuits.
Trebor
Tesco lists Trebor Mighties Extra Strong Sugar Free Mints as a 12.5g confectionery pack.
- The listed ingredients identify sorbitol and sucralose, making the sweetener blend clear.
- The mint listing does not provide biscuit-recipe directions.
Smint
Tesco’s Smint Single 8G listing identifies a small mint product containing xylitol and aspartame.
- The ingredient list identifies the sweeteners for shoppers comparing mint products.
- The listing carries an excessive-consumption warning; the NHS says aspartame is unsuitable for people with PKU.
Peppersmith
Waitrose lists Peppersmith Peppermint as sugar-free mints made with xylitol and peppermint oil.
- Waitrose labels the listed product as suitable for vegans and free from aspartame.
- Those product declarations do not establish a method for using the mints in biscuit dough.
Sulá
Waitrose lists Sulá Mint Humbugs as mint confectionery containing isomalt, cream, butter and soya lecithin.
- The listed ingredients distinguish these humbugs from the pressed mints above.
- Check dietary suitability carefully: the listing includes dairy and soya ingredients and an excessive-consumption warning.

Questions about mints and baking
Can crushed sugar-free mints replace caster sugar in biscuits?
Do not treat them as a like-for-like replacement. Tesco Real Food’s Christmas biscuits recipe specifies 115g golden caster sugar, while the mint listings describe ready-to-eat sweets with differing ingredients. UK Scientific Advisory Committee on Nutrition material says non-sugar sweeteners can be used in home baking, but that does not provide a mint-to-sugar substitution method; follow a recipe developed for your chosen baking sweetener.
What matters when choosing mints to serve after biscuits?
Check the exact pack’s sweeteners, allergen declaration, dietary information and consumption warnings. Tesco lists sorbitol in POLO Sugar Free and xylitol and aspartame in Smint Single, while Waitrose lists cream, butter and soya lecithin in Sulá Mint Humbugs.
Do sugar-free mints carry sweetener cautions?
Some do. The NHS says aspartame is unsuitable for people with PKU, and the Tesco Smint Single and Waitrose Sulá Mint Humbugs listings warn that excessive consumption may produce laxative effects. Check the warning on the product you intend to serve.
Does serving a sugar-free mint change the biscuits?
No. A mint eaten separately does not change the ingredients in the biscuits. If your aim is to alter the bake, choose a recipe developed for the baking sweetener you intend to use rather than relying on the mint’s sugar-free label.
