For biscuit baking, choose lactose-free dairy milk if lactose is the issue and the person eating the biscuits can have milk; Arla says its LactoFREE semi-skimmed milk can be used in baking, but it still contains milk. Choose a clearly dairy-free plant drink for a vegan or dairy-free recipe, checking that its ingredients suit the eater. For cow’s-milk allergy, check every recipe ingredient and its allergen information: the Food Standards Agency cautions that a vegan label alone does not guarantee allergy safety.
Who is the bake for?
The reason for changing the milk determines whether lactose-free dairy milk or a dairy-free drink belongs in the recipe.
Bakers with lactose intolerance
Lactose intolerance is different from a milk allergy, as the NHS explains. If milk itself is suitable for the person eating the biscuits, lactose-free dairy milk offers a dairy ingredient; check the rest of the recipe for ingredients that may contain lactose.
Dairy-free or vegan biscuit bakers
Use a drink labelled dairy-free rather than lactose-free dairy milk. Oat drinks are one plant-based option, provided oats suit the intended eater; butter, chocolate and other ingredients also need checking if the whole bake must be dairy-free or vegan.
Bakers catering for cow’s-milk allergy
Avoid lactose-free dairy milk: the Arla product discussed here still lists milk as an allergen. Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products for milk allergy, while the Food Standards Agency cautions that vegan labelling alone does not guarantee allergy safety. Check ingredients and precautionary allergen information across the whole recipe.
What should you check before choosing?
Lactose-free dairy milk
Choose when: lactose is the concern, milk protein is suitable and you want to retain dairy milk in the biscuit recipe.
Bear in mind: lactose-free dairy milk still contains milk, so it cannot make a bake dairy-free or suitable for cow’s-milk allergy.
Dairy-free oat drink
Choose when: the recipe needs a plant-based drink and oats suit the person eating the biscuits.
Bear in mind: the oat base and any allergen warnings need checking; a vegan claim alone is not an allergy-safety check.
| Priority | What to check | Your needs |
| Dietary route | Check whether the drink is dairy milk with lactase or a dairy-free plant drink. Read the milk allergen declaration. | I need to reduce lactose but can have milk, or I need to avoid dairy altogether. Those call for different drinks. |
| Whole recipe | Review butter, chocolate, milk powder, whey, decorations and any prepared dough or icing as well as the drink. | A dairy-free drink will not meet my baking requirement if another biscuit ingredient contains milk. |
| Recipe use | Look for a baking or cooking-use statement for the particular drink. Follow the recipe’s liquid quantity before making other changes. | I want an ingredient identified for cooking or baking rather than assuming every milk alternative will work alike in this biscuit recipe. |
| Plant ingredients | Read the plant base, full ingredients and allergen information. For milk allergy, include precautionary allergen statements in the check. | An oat drink only works for my bake if oats and any stated allergen risks suit the person who will eat it. |
| Sweetness | If sweetness matters to the recipe, compare the current packs’ ingredients and sugars declarations; do not rely on a variant name alone. | I want to know what the drink contributes before adjusting the other biscuit ingredients. |
Mistakes to avoid
-
Treating lactose-free as dairy-free
Arla LactoFREE semi-skimmed milk contains milk. Using it would make a vegan or dairy-free biscuit recipe unsuitable, and it is not an option for cow’s-milk allergy.
Establish whether the requirement concerns lactose, all dairy or milk allergy, then check the drink’s ingredients and allergen declaration.
-
Changing the drink but not the other ingredients
Butter, cream, milk powder, whey or chocolate can introduce milk into biscuits even when the added drink is dairy-free.
Check every ingredient, including decorations and any ready-made dough or icing, against the eater’s requirement.
-
Relying on a vegan label for milk allergy
The Food Standards Agency cautions that vegan food is not an absolute guarantee of safety for people with certain food allergies because cross-contact can matter.
For milk allergy, read both ingredients and precautionary allergen information on the drink and every other ingredient.
-
Assuming all plant drinks have the same ingredients
An oat drink’s ingredients and sugars declaration may differ from those of another drink. A dairy-free description does not establish suitability for someone who must avoid oats or other stated allergens.
Compare the particular packs for their plant base, ingredients, allergen information and sugars declaration before using one in the recipe.
Relevant brand and retailer ranges
These references illustrate the dairy and plant-drink routes; check the individual product label rather than treating a range name as an allergen statement.
Arla LactoFREE
A lactose-free dairy-milk route when milk itself is suitable for the person eating the biscuits.
- Arla says its LactoFREE semi-skimmed milk contains semi-skimmed milk and lactase enzyme and can be used in baking and cooking.
- The product lists milk as an allergen; it is not dairy-free or suitable for cow’s-milk allergy.
Tesco
Tesco’s listed ranges include lactose-free dairy drinks and a separate oat-drink category.
- The listings include Tesco and Arla lactose-free dairy products, alongside oat drinks from several brands.
- A category listing does not establish the ingredients or allergen suitability of an individual drink.
Sainsbury’s
Sainsbury’s listings include own-label lactose-free dairy drinks as well as dairy-free plant drinks.
- Its cited range includes oat, soya and almond drink options alongside lactose-free dairy drinks.
- Check the specific drink’s plant base, ingredients and allergen statement before baking for someone with dietary restrictions.
M&S Food
M&S Food describes separate lactose-free cow’s-milk and dairy-free oat-drink ranges.
- M&S says its lactose-free cow’s milk can be used in recipes and describes its oat-drink range as suitable for cooking.
- Those range descriptions do not replace the ingredients and allergen information on the particular pack.
Waitrose
Waitrose lists Arla lactose-free milk alongside oat, almond and soya alternatives.
- The listed drinks give shoppers both a lactose-free dairy route and several plant-based bases to consider.
- The drinks need individual checks: appearing in the same range does not mean they share ingredients or allergen properties.

Questions about biscuit baking
Is lactose-free milk dairy-free?
No. Lactose-free milk can still be dairy milk: Arla’s LactoFREE semi-skimmed product contains milk and lists it as an allergen. It may be an option when lactose is the issue and milk is suitable, but not for a dairy-free or vegan recipe or for cow’s-milk allergy.
Can I use lactose-free milk in biscuit baking?
Yes, if dairy milk suits the intended eater; Arla says its LactoFREE semi-skimmed milk can be used in baking and cooking. Changing only the liquid milk will not address butter, chocolate or other milk-containing ingredients elsewhere in the biscuits.
Can an oat drink replace milk in dairy-free biscuits?
An oat drink can be a dairy-free route when oats suit the eater. The Waitrose listing for Alpro Oat Original says it can be used in cooking as an alternative to milk; follow the recipe’s liquid quantity initially and check the label of the drink you actually use.
Is a vegan-labelled oat drink enough for milk allergy?
No. The Food Standards Agency cautions that vegan labelling does not guarantee safety for people with certain food allergies because cross-contact can occur. For cow’s-milk allergy, check ingredients and precautionary allergen information for the drink and every other biscuit ingredient.
