Start with an unsweetened soya drink if you want the biscuit recipe’s sugar and flavourings to determine the sweetness; The Vegan Society’s cookie recipe uses soya milk alongside other ingredients. If independent vegan certification matters, check the exact carton for the Vegan Trademark. A vegan label does not establish that a drink is free from milk-allergen cross-contact, so read the current allergen information when that risk matters.
If the dough already contains sugar, chocolate or other flavourings, an unsweetened drink lets you follow the recipe without adding sweetness through the liquid. The Vegan Society uses soya milk in its choc chip cookie recipe.
If a manufacturer’s vegan statement is not enough for your purposes, check the exact carton for the Vegan Trademark. The Vegan Society says registered products are assessed against its standards and the registration is renewed yearly.
A vegan label alone is not an allergen-free claim. UK Government food-labelling guidance says animal-origin allergens can be present through cross-contact, so check the current ingredient, allergen and precautionary statements.
Choose the drink to suit the recipe’s sweetness, then check the exact carton for the ingredients, vegan assurance and allergen information that matter to your household.
| Priority | What to check | Your needs |
|---|---|---|
| Vegan assurance | Read the vegan statement on the exact carton. If you want independent certification, look for the Vegan Trademark rather than assuming a vegan-labelled product carries it. | I want to know whether the carton meets my vegan requirements and whether its status has been independently checked. |
| Sweetness | Check whether the drink is unsweetened, no-sugars or sweetened, then read its sugars declaration. Compare figures only when they use the same basis, such as per 100 ml. | The dough already contains sugar or chocolate, so I want to avoid adding sweetness through the soya drink. |
| Ingredients and fortification | Read the ingredient list and nutrition panel for added calcium, iodine and vitamins, or for the shorter organic formulation you prefer. Check any nut advisory separately. | I may want a fortified drink for use beyond this recipe, or I may prefer a shorter ingredient list; those are different reasons to choose a carton. |
| Storage and quantity | Check whether the carton is chilled or UHT, its pack quantity and its storage directions after opening. | I bake occasionally and want a carton size and storage format I can use as directed. |
| Allergen information | For milk-allergen risk, read the current allergen and precautionary statements; do not use vegan wording as a substitute for a relevant allergen-free claim. | I need to assess milk cross-contact separately from vegan suitability. In a December 2023 online survey of 821 screened respondents by the Food Standards Agency and Ipsos UK, 53% of respondents with a food hypersensitivity to an animal-origin allergen, and 50% of those who shopped for someone with one, already knew that vegan products might be unsuitable because of cross-contamination. These were awareness measures, not soya-drink preferences. |
UK Government guidance distinguishes vegan labelling from an allergen-free claim: animal-origin allergens can be present through cross-contact.
If milk allergy is a concern, read the current ingredient list, allergen declaration and precautionary statements rather than relying on the word “vegan”.
A product described as vegan does not necessarily carry the Vegan Society’s separate Vegan Trademark certification.
If third-party certification matters to you, check for the mark on the exact carton.
A sweetened carton contributes sugar alongside any sugar or chocolate already in the dough. Retailer listings show that soya drinks differ in their declared sugars.
Use an unsweetened drink when you want to follow the recipe’s existing sweetness; check the current nutrition panel before making a substitution.
Waitrose lists Plenish Organic No Added Sugar Soya as a two-ingredient drink with a may-contain-nuts advisory, while its Essential Unsweetened Soya Drink lists added calcium and vitamins.
Choose according to the ingredient or fortification features you want, and check allergen advice independently.
These examples illustrate different carton labels and formulations; check the product you intend to buy, as details can differ between variants.
A branded route for shoppers considering a no-sugars soya drink.
Own-label unsweetened soya drinks include chilled and UHT long-life formats.
Its listings offer a contrast between a fortified Essential unsweetened drink and a shorter-ingredient Plenish option.
M&S lists both sweetened and unsweetened soya drinks, making the variant important for a biscuit recipe.
An organic option for shoppers who prioritise a short ingredient list.
A route to consider when Vegan Trademark certification is a purchasing priority.
These Alpro options offer two different choices for biscuit baking: a no-sugars long-life drink in an 8 × 1 L pack and a Plant Protein drink whose listing includes sugar. Check the recipe and the current carton before substituting either one.

Consider this long-life option when you want the biscuit recipe to control sweetness. The listed 8 × 1 L pack may be more than you need for occasional baking; check the current cartons for vegan certification and allergen precautions if those affect your purchase.

This vegan-described Plant Protein drink is a different choice from an unsweetened carton: its listing includes sugar. Check its current sugars declaration against the biscuit recipe, and read the allergen statements if cross-contact matters.
Not on the strength of its vegan label alone. UK Government guidance says vegan labelling does not guarantee the absence of animal-origin allergens from cross-contact. Check the exact pack’s allergen and precautionary information and, where absence of milk is required, look for an appropriate milk-free claim.
The Vegan Society says its Trademark identifies products checked against standards covering animal-derived ingredients, animal testing and minimising cross-contamination, with registration renewed yearly. Check for the mark on the exact carton, and still read allergen information if you need it.
Choose unsweetened when you want the recipe’s own sugar and flavourings to set the sweetness. Retailer panels show that drinks differ: Tesco lists 0.4 g sugars per 100 ml for its unsweetened drink, while M&S lists 2.0 g per 100 g for its sweetened Plant Kitchen drink. Those figures use different measurement bases, so read the current pack before comparing products or changing a recipe.
Yes, if it is the type and amount of liquid the recipe calls for. Tesco lists a vegan-labelled UHT unsweetened soya drink; follow the carton’s storage directions after opening rather than treating its unopened storage conditions as instructions for an opened pack.
The current pack is the one to use for ingredients, nutrition, vegan claims and allergen advice, especially when a particular certification, fortification or precautionary statement affects your choice. Product formulations and labels can change.
