For a continental breakfast where sugar-free is essential, choose a biscuit labelled sugar-free rather than assuming free-from custard creams qualify: Tesco, Sainsbury’s and Asda list 19.9 g, 24.9 g and 25 g sugars per 100 g for their free-from custard creams, respectively. A Gullón sugar-free vanilla wafer offers a cream filling but is not a custard cream; its sugar-free digestives are a plainer alternative. Check the exact pack for sugars, sweeteners and allergens before serving.
Who is this choice for?
Breakfast hosts buying for a sugar-free requirement
If you are putting biscuits alongside bread, fruit and hot drinks, check the sugar claim on the exact biscuit you plan to serve. A gluten-free or milk-free custard cream answers a different requirement.
Shoppers who want a vanilla filling
If the filling matters more than the traditional custard-cream shape, a sugar-free vanilla wafer is an alternative to consider. If a plain biscuit will do, a sugar-free digestive is another format.
People comparing the whole nutrition label
If carbohydrate, energy or portion size matters to your choice, read those figures as well as sugars. A sugar-free claim does not tell you everything about a biscuit’s nutrition.
What should you check before buying?
Start with the requirement that cannot be compromised, then decide how closely the biscuit needs to resemble a custard cream. Compare nutrition figures on the same per-100 g basis before considering your usual portion.

What to check |
Your needs |
| Sugars |
Read the sugar claim and the “of which sugars” figure per 100 g on the exact pack. Tesco Groceries, Sainsbury’s and Asda list 19.9 g, 24.9 g and 25 g sugars per 100 g for their respective free-from custard creams. |
I need a biscuit labelled sugar-free, not one labelled free from gluten or milk. Those supermarket custard creams do not meet that need. |
| Biscuit format |
Check whether you are buying a filled wafer, a plain digestive or a custard cream. Gullón describes its sugar-free vanilla wafer as having a vanilla-flavoured cream filling; its sugar-free digestive is a wheat biscuit. |
The vanilla filling is the part I want to keep, so I could serve a wafer instead of a custard cream. If a plain biscuit is fine, a digestive gives me another choice. |
| Nutrition and portions |
Compare energy, carbohydrate and sugars using the same label basis, then look at the serving size and number of biscuits you expect to put out. |
I want to know what a realistic portion contains, rather than using “sugar-free” as a shorthand for the entire nutrition label. |
| Allergens |
Read the ingredient list and precautionary statements on the exact pack. Gullón identifies wheat in its sugar-free digestive; its vanilla wafer contains wheat and soya according to the product information. |
Someone at breakfast needs to avoid a particular ingredient, so I must check the biscuit I will actually serve. A sugar-free choice does not automatically meet a gluten-free or milk-free need. |
| Sweeteners |
Check the named sweeteners and any consumption warning. Gullón lists isomalt and maltitol for its sugar-free digestive. |
I want guests to be able to read the pack information, particularly if they need to consider sweeteners or their portion size. |
What can go wrong?
-
Reading “free from” as “sugar-free”
Free-from custard creams can address gluten or milk requirements while still containing sugar. Tesco Groceries, Sainsbury’s and Asda list between 19.9 g and 25 g sugars per 100 g for the free-from custard creams described here.
Look for the sugar claim and compare the “of which sugars” figure on the exact pack; check gluten-free and milk-free claims separately.
-
Letting the sugar claim stand in for the whole label
Sugar-free does not describe a biscuit’s energy, total carbohydrate or serving size. Those details matter if you are comparing what to put on the breakfast table.
Read the per-100 g figures, then check the figures for the number of biscuits you would serve.
-
Overlooking ingredients in sugar-free alternatives
The Gullón sugar-free biscuits described here use sweeteners and contain wheat; the vanilla wafer also contains soya. A substitute chosen for its sugar claim may therefore conflict with a guest’s ingredient requirements.
Keep the packet available and check its ingredient, allergen and consumption statements before serving.
-
Expecting a substitute to be a custard cream
A vanilla-filled wafer preserves a filling, while a digestive is a plain biscuit. Neither has the traditional custard-cream format.
Decide whether the filling or the familiar biscuit shape matters more before choosing an alternative for a sugar-free breakfast spread.

Frequently asked questions
Are Tesco, Sainsbury’s and Asda free-from custard creams sugar-free?
No. Tesco Groceries lists 19.9 g sugars per 100 g for its free-from custard creams, Sainsbury’s lists 24.9 g and Asda lists 25 g. Their free-from descriptions concern requirements such as gluten or milk avoidance, not sugar-free status.
What if I want a sugar-free biscuit with a vanilla filling?
Gullón describes its ZERO Sugar Free Vanilla Wafer as a vanilla-cream-filled, sugar-free wafer. It offers a filling, but it is not a traditional custard cream; check the exact pack for wheat, soya, sweeteners and precautionary allergen statements.
Does sugar-free tell me how much carbohydrate or energy a biscuit contains?
No. Compare the carbohydrate and energy figures as well as sugars, using the same per-100 g basis and then the portion you expect to serve. Diabetes UK cautions that foods marketed for diabetes can still contain comparable fat and calories to similar products, so a front-of-pack claim should not replace a look at the full label.
What should I check when serving biscuits to guests?
Keep the exact packet available so guests can check ingredients, allergens and sweetener information. The Gullón sugar-free alternatives described here contain wheat, while the supermarket free-from custard creams address different dietary requirements and are not sugar-free.
