For a biscuit recipe that calls for dairy milk, start with a plain, unsweetened soya drink and substitute it 1:1 unless the recipe says otherwise. King Arthur Baking’s guidance supports that substitution for the milk component, but the drink’s sugar level can affect the result, and you must check butter, chocolate and other ingredients separately if the finished biscuits need to be dairy-free.
If your biscuit recipe includes milk, a plain, unsweetened soya drink is a starting point for replacing that liquid ingredient. King Arthur Baking’s baking guidance recommends a 1:1 substitution for unflavoured, unsweetened non-dairy milk; it does not mean every ingredient or recipe will behave identically.
If you want the recipe’s measured sugar to determine sweetness, compare drinks labelled no sugars or unsweetened with sweetened versions. The drink’s sugar content is worth checking before you change an established biscuit recipe.
If you are baking for someone avoiding milk or other ingredients, read the current labels for the drink and every other recipe component. Soya itself is an allergen, and some soya drinks also carry nut-related warnings.
Choose for the recipe first, then check the drink’s sugar level, allergen information and storage instructions on the carton you buy.
| Priority | What to check | Your needs |
|---|---|---|
| Milk substitution | Choose a plain, unflavoured drink. For a recipe calling for milk, start with King Arthur Baking’s 1:1 non-dairy-milk substitution unless the recipe gives different instructions; assess the rest of the recipe separately. | I’m replacing the milk in an existing biscuit recipe, not assuming the same drink can replace its butter or eggs. |
| Sweetness | Read the sugars figure per 100 ml and distinguish no-sugars or unsweetened drinks from sweetened ones. Waitrose & Partners lists 0 g sugars per 100 ml for Alpro No Sugar Chilled and 2.5 g per 100 ml for Essential Original. | I want to know whether the drink adds sugar before deciding if it suits the biscuit recipe. |
| Ingredients and allergens | Check the current ingredients and allergen statement for the drink and the other biscuit ingredients. The Food Standards Agency identifies soya as an allergen; the cited Plenish and M&S drinks also have nut-related warnings. | If I’m baking for someone with an allergy, a dairy-free label alone does not answer whether the full recipe is suitable. |
| Storage | Check whether an unopened carton needs chilling and follow its own instructions after opening. The cited Waitrose & Partners listings say to use Alpro No Sugar Chilled within five days and Plenish Organic Soya within four days of opening; M&S specifies three days for its Unsweetened Soya Drink. | I bake occasionally and want a carton size and opened-pack period that fit how much I’ll use. |
Sweetened and unsweetened drinks differ in sugar content, which matters when a biscuit recipe already specifies its sugar.
For an existing recipe, start with plain, unsweetened soya and try a small batch before changing several ingredients at once.
Butter, milk chocolate, icing or other ingredients may still contain milk. Eggs are not dairy, but they do matter if the bake must also be vegan.
Check the complete recipe and the current labels of every ingredient against the requirements of the person who will eat the biscuits.
The Food Standards Agency identifies soya as an allergen. Waitrose & Partners lists a “may contain nuts” warning for Plenish Organic Soya, while M&S says its Unsweetened Soya Drink is not suitable for people with nut or peanut allergy.
Read the current pack, including precautionary statements, before baking for someone with an allergy. Do not use a soya drink for someone with a soya allergy.
Opened-pack refrigeration and use periods differ between drinks, even when unopened cartons can be stored outside the fridge.
Check the specific carton’s instructions and consider how much you will use before opening another one.
An opened carton left unused beyond its stated period may need to be discarded.
These product examples illustrate different label and storage checks; a brand name alone does not establish that every drink in its range has the same ingredients.
The cited No Sugar Chilled Soya Drink is an example for recipes where added sweetness from the drink is unwanted.
The cited Organic Soya drink offers a short ingredient list for bakers who prefer to check exactly what is in the carton.
The cited Unsweetened Soya Drink is another option to compare with a recipe’s intended sweetness.
The cited Original Soya Drink is a sweetened option to consider when its sugar content fits the biscuit recipe.
These soya drinks cover no-sugars, organic and sweetened options for recipes that call for milk. Compare the pack size and current ingredients before choosing for a particular bake.

Consider this long-life, no-sugars option when you want to keep the drink’s added sweetness out of a biscuit recipe. The pack contains eight 1L cartons; check that quantity against how often you bake. Joybuy’s ingredient listing includes soya beans, so check the current pack if you are baking for someone with allergies.

This is an organic soya-drink option to consider when the ingredient list matters to your biscuit recipe. Check the current pack for its ingredients, allergen statements and carton quantity before ordering; do not assume it has the same formulation as another Alpro drink.

Consider this soya drink only after checking whether its sweetness suits the biscuit recipe. The carton is 1L; read its current sugars figure, ingredients and allergen statement rather than treating it as equivalent to a no-sugars drink.

The three 300ml cartons offer a different pack format from a 1L carton. If using this drink in biscuits, check its sweetness against the recipe and read the current ingredients, allergen statement and instructions for an opened carton.
Usually, for the milk component: King Arthur Baking recommends a 1:1 substitution with unflavoured, unsweetened non-dairy milk unless your recipe specifies otherwise. Soya is a starting point, but a milk substitution does not replace butter or other ingredients containing dairy.
Start with plain, unsweetened soya when following a biscuit recipe whose sugar you do not want to change. If you choose a sweetened drink, read its sugars figure and consider that added sweetness when assessing the recipe.
No. The Food Standards Agency identifies products containing soya as a possible risk for people with a soya allergy. Use an appropriate non-soya ingredient instead and check the current labels of all ingredients for allergen and precautionary statements.
No. Eggs are not dairy, so biscuits can be dairy-free while still containing eggs. For a vegan bake, check every ingredient, including any butter substitute, chocolate and icing, rather than relying on the choice of drink.
Follow the specific carton’s refrigeration and use instructions. The cited Waitrose & Partners listings specify five days after opening for Alpro No Sugar Chilled and four days for Plenish Organic Soya; M&S specifies three days for its Unsweetened Soya Drink. Storage instructions for unopened cartons do not replace the opened-pack directions.
