What should you check?
Decide which sugar claim the recipe requires first, then check the ingredients and whether the biscuit is suitable for the dessert you plan to make.
| Priority | What to check | Your needs |
| Sugar claim |
Read the exact claim and sugars per 100g. Sainsbury’s lists Siro as sugar-free with 0.5g sugars per 100g; it lists McVitie’s The Light One as reduced sugar, with sugar and syrup in its ingredients. |
My recipe or guest requirement calls for sugar-free biscuits, so a reduced-sugar or no-added-sugar label alone will not do. |
| Sweeteners |
Check the sweetener list and any consumption warning. Gullón lists isomalt and maltitol; Sainsbury’s lists 13g polyols per 100g for Siro and shows an excessive-consumption laxative-effect warning. |
If several portions will be served, I want to know which sweeteners are in the biscuits and what the pack says about consumption. |
| Allergens |
Read the current pack’s ingredients and precautionary statements. Siro and Gullón contain wheat and may contain milk and soya; Tesco lists wheat, milk and soya for Diablo, with possible tree nuts, sesame and mustard. |
Guests’ allergy requirements determine which biscuit I can use; a sugar-free claim does not answer that question. |
| Baking use |
Look for guidance relevant to your dessert. Tesco specifically describes Diablo as a base for no-added-sugar cheesecake; for an unfamiliar biscuit, try a small base before making a large dessert. |
I want the crushed biscuit to work in my recipe without assuming every digestive will produce the same base. |

Questions about baking with digestives
How can I check whether a digestive is sugar-free?
Look for an explicit sugar-free claim and read the sugars figure per 100g on the current pack. For example, Sainsbury’s lists Siro Sugar Free Digestive Biscuits at 0.5g sugars per 100g; a reduced-sugar or no-added-sugar label is not the same claim.
Is no added sugar the same as sugar-free for a Christmas bake?
No. If the recipe or guest requirement specifically calls for sugar-free biscuits, choose an explicitly sugar-free product rather than relying on a no-added-sugar label. Tesco describes Diablo Digestive Cookies as no added sugar, while Sainsbury’s lists Siro as sugar-free.
Can no-added-sugar digestives make a cheesecake base?
Yes, when a sugar-free claim is not required: Tesco specifically describes Diablo No Added Sugar Digestive Cookies as suitable for a no-added-sugar cheesecake base. Check the current pack for maltitol and allergens before serving.
Why do some sugar-free digestives carry a laxative-effect warning?
Some use polyol sweeteners, and the amount eaten matters. Sainsbury’s lists 13g polyols per 100g for Siro and displays an excessive-consumption laxative-effect warning, so read the pack when deciding how much to use in a dessert.
Are these biscuits suitable for a gluten-free dessert?
The Siro, Gullón, Diablo and McVitie’s products discussed here contain wheat. For a gluten-free dessert, choose a separately verified gluten-free biscuit and check that its sugar claim also meets the recipe’s requirements.
