Home bakers avoiding lactose
If cow’s milk is otherwise suitable for you, lactose-free dairy lets you follow a recipe that calls for milk. It is not the right route for a milk-protein allergy.
Who is this for?
Bakers following a dairy biscuit recipe
When a recipe names whole, semi-skimmed or skimmed milk, look for the corresponding lactose-free type rather than treating every carton as the same ingredient.
Bakers making milk-free or vegan biscuits
Start with a recipe intended for a dairy-free alternative. Check the drink and the other ingredients, including any butter substitute, flour and eggs, against the bake’s requirements.
What matters when choosing milk?
Decide whether the biscuits need to be milk-free before matching the milk type in the recipe. A change of milk type is worth checking against the recipe rather than assuming the finished biscuits will turn out the same.
| Priority | What to check | Your needs |
|---|---|---|
| Milk or milk-free | Read the ingredient and allergen declarations. Lactose-free cow’s milk still contains milk; a plant drink needs its own allergen check. | I need to avoid lactose, but can I use cow’s milk? If the bake must be milk-free, I need a dairy-free recipe instead. |
| Recipe milk type | Match whole, semi-skimmed or skimmed milk where the recipe specifies one. Arla Foods UK lists 3.6g fat per 100g for its LactoFREE whole milk; Tesco lists 1.7g per 100ml for its lactose-free semi-skimmed drink and 0.1g per 100ml for its skimmed drink. | My recipe names a particular type of milk, so I want its lactose-free counterpart rather than an untested substitution. |
| Other ingredients | Check the current packs for butter, flour, chocolate and decorations as well as the drink. GOV.UK’s allergen guidance lists milk, eggs and cereals containing gluten among the 14 allergens. | When baking for someone with an allergen restriction, I need the finished biscuits—not just the milk choice—to meet it. |
What should you avoid?

Reading “lactose free” as “milk free”
Lactose-free cow’s milk can still contain milk protein. Royal United Hospitals Bath NHS Foundation Trust distinguishes a milk-protein allergy from lactose intolerance, and M&S states that its lactose-free milk is not suitable for a dairy allergy.
For a milk-free bake, choose a dairy-free recipe and check the allergen declarations on the drink and every other ingredient.
-
Ignoring the milk type in the recipe
Whole, semi-skimmed and skimmed lactose-free products have different stated fat values. That difference does not establish how a particular biscuit recipe will turn out after a swap.
Start with the lactose-free version of the type named in the recipe. If you change it, consult the recipe’s substitution guidance or try a small batch.
-
Using an online listing instead of the current pack
Retailers including Sainsbury’s advise that product ingredients can change. An older listing may not reflect the carton used for baking.
Read the ingredients and highlighted allergens on each current pack, especially when replacing several ingredients for an allergy-restricted bake.
Brand and retailer references
These examples show the kinds of lactose-free dairy available for different recipes; the name on a carton does not replace checking its current label.
Arla LactoFREE
Arla Foods UK lists fresh and long-life lactose-free milk types. Its whole LactoFREE milk page specifically names baking as a use.
- The whole milk lists 3.6g fat per 100g.
- It declares milk as an allergen, so it is not a milk-free option.
Tesco
Tesco lists own-label lactose-free semi-skimmed and skimmed dairy drinks for recipes specifying those milk types.
- Tesco lists 1.7g fat per 100ml for the semi-skimmed drink and 0.1g per 100ml for the skimmed drink.
- Both are milk-containing products; check the current pack for ingredients and allergens.
Sainsbury’s
Sainsbury’s lists Everyday lactose-free semi-skimmed and whole dairy drinks.
- The Everyday semi-skimmed listing identifies cow’s milk, reconstituted lactose-reduced milk and lactase enzyme.
- Sainsbury’s advises that ingredients can change; use the current pack for the final check.
M&S Made Without Lactose
M&S lists whole and semi-skimmed lactose-free cow’s milk and says these products can be used in recipes.
- The whole milk’s listed ingredients include skimmed milk, reconstituted lactose-reduced milk, cream and lactase enzyme.
- M&S states that its lactose-free products are not suitable for a dairy allergy or galactosaemia.
Waitrose
Waitrose lists Arla LactoFREE milk in its lactose-free category.
- The category includes Arla whole and skimmed lactose-free options for checking against a recipe.
- Check the individual product and its current pack rather than relying on the category name for allergen suitability.
Joybuy products for dairy-free baking
This oat drink is an option to consider for a dairy-free biscuit recipe that allows oat drink; it is not lactose-free cow’s milk for a recipe specifying whole, semi-skimmed or skimmed dairy milk.

Consider this oat drink where a dairy-free biscuit recipe allows one. Check the current pack for allergens, including oats; if replacing the milk in a dairy recipe, follow its substitution guidance or try a small batch.
Common questions
Is lactose-free milk suitable for a milk allergy?
No, lactose-free cow’s milk still contains milk protein. Royal United Hospitals Bath NHS Foundation Trust explains that milk allergy concerns milk protein rather than lactose, and M&S explicitly says its lactose-free milk is not suitable for a dairy allergy.
Can I use lactose-free whole milk in biscuits?
Yes, if cow’s milk is suitable for the people eating them and the recipe calls for milk. Arla Foods UK names baking as a use for its LactoFREE whole milk; match the milk type specified by your recipe where possible.
What else should I check when baking lactose-free biscuits?
Check the entire recipe and the current packs, not just the milk carton. Butter can also be a dairy ingredient, while GOV.UK’s allergen guidance identifies eggs, cereals containing gluten, soybeans, peanuts, sesame and tree nuts among the allergens that may matter for other biscuit ingredients.
