Repeat biscuit bakers
If you bake several batches over time, compare a case of individual cartons with the amount you expect to use and the space available to store them.
Who is this for?
Bakers replacing dairy milk
If your biscuit recipe calls for liquid milk, consider an unflavoured oat drink and whether its slight sweetness suits the recipe.
Ingredient- and allergen-conscious households
If gluten, oats, wheat or particular ingredients matter in your household, check the exact carton. Vegan positioning alone does not answer those questions.
What should you check?
Start with the recipe and the number of batches you plan to bake, then check the carton’s ingredients, allergen information and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe fit | Check that the recipe calls for liquid milk. Silver Spoon suggests replacing 250ml of cow’s milk with 250ml of oat drink; it also notes oat drink’s slightly sweet flavour. | For savoury biscuits, I want an unflavoured drink and may try a small batch before making more. |
| Pack size and storage | Compare a single carton with 6 x 1L or 8 x 1L cases. Read the unopened-storage directions and the use-by instructions that apply after each carton is opened. | I bake regularly enough to use a case, but need to finish opened cartons within their label instructions. |
| Allergens | Read the exact ingredients and allergen statement, including any gluten-free claim. The Food Standards Agency notes that oats remain an allergen even when a product is labelled gluten free. | If oats, wheat or gluten are a concern in my household, I need the specific carton’s labelling rather than a general vegan claim. |
| Formulation | Compare ingredients and nutrition per 100ml on the products you are considering. A barista label describes a coffee-oriented formulation; it does not establish a biscuit-baking advantage. | I may use the same carton for coffee and baking, or prefer a shorter ingredient list, but those are separate reasons to choose a drink. |
Buying pitfalls
-
Assuming every oat drink will taste the same in biscuits
Silver Spoon notes oat drink’s slight sweetness and says dairy-free alternatives may give a less rich result than cow’s milk. That matters particularly in a savoury recipe.
Start with an unflavoured drink and the recipe’s stated milk volume; try a small batch when flavour or richness is important.
-
Choosing a case without planning when to open it
A multipack contains separate cartons, each of which needs to be stored according to its own label after opening. Sainsbury’s cited long-life oat drink, for example, says to refrigerate it and use it within 3 days of opening.
Match the number of cartons to your planned batches and household use, and follow the instructions on the pack you buy.
-
Treating vegan as an allergen statement
Oat drinks have different product-specific warnings. Minor Figures labels its cited Barista Oat gluten free, while M&S says its Only 3 Ingredients Oat Drink is unsuitable for coeliacs and people with a wheat allergy.
Check the current ingredients, allergen statement and any gluten-free claim on the exact product.
-
Assuming barista means better biscuits
Barista positioning concerns uses such as coffee. Oatly says its Barista Edition can also replace milk in cooking and baking, but that does not establish a better biscuit result than a standard oat drink.
Choose a barista version if its ingredients or dual coffee-and-baking use suit you, rather than treating the label as a baking-performance claim.

Oatly
Oatly lists several oat-drink variants; its Barista Edition page lists 0.5L, 1L and 1.5L sizes.
- Oatly says Barista Edition can replace milk in cooking and baking.
- Its coffee-focused claims do not establish a better result in biscuits.
Alpro
Alpro Oat Original is listed as a 1L long-life drink at Tesco; Joybuy also lists Original, No Sugars and Barista Oat case formats.
- An 8 x 1L case is a format to consider for repeated baking.
- Check the exact variant’s ingredients and allergen statement rather than applying one carton’s details to the range.
Minor Figures
Minor Figures presents Barista Oat in a 6 x 1L pack and labels that product gluten free.
- Its listed ingredients include water, oats, rapeseed oil, tricalcium phosphate, dipotassium phosphate and salt.
- Coffee-oriented positioning does not establish how it will compare in a biscuit recipe.
Tesco
Tesco lists its own long-life oat drink alongside 1L oat drinks from Oatly and Alpro.
- The range provides single-carton options to compare by variant and label.
- Check the particular carton’s ingredients and availability when buying.
Sainsbury’s
Sainsbury’s lists both a standard long-life oat drink and a barista version in 1L cartons.
- The two named products allow a comparison of their ingredients and nutrition per 100ml.
- The cited standard product says to refrigerate and use it within 3 days after opening; follow the instructions on the exact carton purchased.
M&S
M&S offers a chilled 1L Only 3 Ingredients Oat Drink containing water, oats and sea salt.
- The named product has a short ingredient list and is not fortified.
- M&S says it is unsuitable for coeliacs and people with a wheat allergy; it must be refrigerated and used within 3 days of opening.

This No Sugars variant comes as eight 1L long-life cartons for repeat use. If sugar content matters to your recipe, check the nutrition and ingredients on the current carton rather than relying on the variant name alone.
Frequently asked questions
Can I replace dairy milk with oat drink in biscuit dough?
If the recipe calls for liquid milk, Silver Spoon suggests starting with the same volume of oat drink: 250ml for 250ml. Its slight sweetness may be noticeable in savoury biscuits, so try a small batch if flavour is important.
Should I buy regular or barista oat drink for biscuits?
An unflavoured regular oat drink is a straightforward starting point; a barista version may make sense if you also use it for coffee or want its particular ingredients. Oatly says its Barista Edition can replace milk in baking, but coffee-focused claims do not establish a biscuit-baking advantage.
Is every oat drink gluten free?
No. Check the claim and allergen information on the exact carton. The Food Standards Agency says a food labelled gluten free must contain no more than 20mg/kg gluten as sold, and oats must still be identified as an allergen. Minor Figures labels its cited Barista Oat gluten free, whereas M&S says its cited Only 3 Ingredients Oat Drink is unsuitable for coeliacs.
Does a vegan label answer oat- or wheat-allergy concerns?
No. Read the exact product’s ingredient and allergen information: oats are themselves an allergen, and M&S explicitly says its Only 3 Ingredients Oat Drink is unsuitable for people with a wheat allergy.
How should I store a carton after opening it?
Follow the instructions on that carton, even if it was sold as long life. The cited Sainsbury’s standard oat drink says to refrigerate it and use it within 3 days after opening; other products’ instructions may differ.
