For regular cake baking, an Oatly Barista Edition 6 × 1L case combines a multi-carton format with Oatly’s instructions to use the drink where a recipe specifies milk. Minor Figures Organic Barista Oat is another 6 × 1L option if organic ingredients matter more to you, but its product guidance focuses on coffee, so try it in your cake recipe first. For occasional baking, a single refrigerated carton may make more sense if you can use it within its stated storage period.
A multi-carton case gives you separate cartons to open as needed. Oatly’s Barista Edition guidance explicitly covers replacing milk in a baking recipe; plan how you will use each opened carton within the period on its label.
Minor Figures Organic Barista Oat comes in a 6 × 1L case, according to Minor Figures. Its product guidance centres on coffee, so make a trial cake before relying on it for an occasion.
M&S Only 3 Ingredients Oat Drink contains water, oats and sea salt. It is a chilled 1L carton rather than a case, and M&S says to use it within three days of opening.
Choose it when: You bake repeatedly and want Oatly’s explicit milk-substitution guidance alongside a 6 × 1L format.
Bear in mind: Its formula includes rapeseed oil and an acidity regulator, rather than only oats, water and salt.
Choose it when: You want six 1L cartons made with organic oats and organic rapeseed oil.
Bear in mind: Minor Figures describes coffee use rather than giving a cake-recipe substitution instruction.
Choose it when: You bake occasionally and prefer a single carton with three listed ingredients.
Bear in mind: It needs chilled storage and must be consumed within three days of opening, according to M&S.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe substitution | Look for baking directions for the exact oat drink. Oatly says its Barista Edition can replace milk where a recipe calls for it; a barista label alone does not specify a cake result. | I want a starting point for the milk quantity in my usual recipe, and I can make a trial cake before an important bake. |
| Pack and storage | Check the carton count, unopened storage instructions, best-before dates and how long each carton keeps after opening. The Joybuy Oatly 6 × 1L listing says to refrigerate after opening and use within seven days; M&S gives its chilled carton three days. | Will I use a case one carton at a time, or do I only need enough for a near-term cake? |
| Allergen labelling | Read the exact carton’s oat, wheat and gluten statements. Minor Figures Organic Barista Oat says it may contain gluten; M&S says its three-ingredient drink is not suitable for coeliacs or people with a wheat allergy. | If someone eating the cake needs gluten-free food, I need to check for a current gluten-free claim on the product I actually buy. The Food Standards Agency notes that oats remain an allergen even in food labelled gluten-free. |
| Ingredients | Compare the exact ingredient lists rather than assuming oat drinks have the same formula. M&S lists water, oats and sea salt and says its drink is not fortified; Oatly Barista Edition lists rapeseed oil and added minerals and vitamins. | A short ingredient list or a particular formulation matters to me, but neither tells me by itself how my cake will turn out. |
Oatly gives baking substitution directions for Barista Edition, while Minor Figures describes its Organic Barista Oat chiefly in relation to coffee. Neither statement establishes an identical texture in every cake.
Use directions for the exact drink as your starting point, then make a trial cake before an occasion where the result matters.
An unopened case and an opened carton have different storage needs. The Joybuy Oatly six-pack listing says to refrigerate an opened carton and consume it within seven days; M&S specifies three days for its chilled drink.
Check the best-before dates and opening instructions, then consider how many cartons your household will use.
A carton left open beyond its stated use period may go to waste.
Minor Figures says its Organic Barista Oat may contain gluten, and M&S marks its three-ingredient drink as unsuitable for coeliacs. An oat-based name does not resolve either warning.
If gluten-free suitability is required, check the current gluten-free claim and allergen statement on the exact carton. The Food Standards Agency also identifies oats as an allergen in their own right.
Oatly’s UK Barista Edition range includes a product page with cooking and baking substitution directions. A separate Joybuy listing identifies a 6 × 1L case.
Minor Figures lists Organic Barista Oat in a 6 × 1L case.
M&S lists a chilled, single-carton oat drink made with water, oats and sea salt.
Tesco lists Alpro Oat Original as a 1L long-life drink; Alpro says its UK oat drinks use British oats.
Tesco’s oat-drink category includes its own-label 1L drink alongside other brands.
This supplied ordering combines confirmed case size with the baking guidance given by Oatly and Minor Figures; it is not an independent cake-texture test or a third-party league table.
| Rank | Oat drink | Main specifications | Reason for position | Platform |
|---|---|---|---|---|
| 1 | Oatly Barista Edition 6 × 1L | Six 1L cartons; the Joybuy listing names oats and rapeseed oil among the ingredients. | Oatly’s Barista Edition directions explicitly cover using the drink where a recipe specifies milk, alongside the case format shown by Joybuy. This is a guidance-and-format judgement, not a tested cake result. | Joybuy |
| 2 | Minor Figures Organic Barista Oat 6 × 1L | Six 1L cartons; Minor Figures lists organic oats and organic rapeseed oil. | Minor Figures confirms the case and ingredients, but its product guidance focuses on coffee rather than substituting the drink in cake recipes. | Minor Figures |
These multi-carton oat drinks are options for households planning more than one cake or other uses for the remaining cartons. Check the baking guidance and storage instructions for the exact drink you choose.

Oatly says to use its Barista Edition oat drink where a recipe specifies milk, so the recipe’s milk volume is a starting point. Cake recipes vary; make a trial bake if the result matters for an occasion.

Not necessarily: check the exact carton for a current gluten-free claim and allergen information. Minor Figures says its Organic Barista Oat may contain gluten, while M&S says its three-ingredient drink is unsuitable for coeliacs. The Food Standards Agency also notes that oats remain an allergen even when a food is labelled gluten-free.
Choose according to the ingredient list and product-specific baking directions you need, then trial the drink in your recipe. M&S lists water, oats and sea salt for its chilled drink; Oatly’s Barista Edition has a different formula and explicit milk-substitution guidance. Neither formula guarantees the same result in every cake.
