Bakers who need a gluten-free cake
Check the soya drink’s current gluten-free claim, then check the flour, raising agent, fillings and decorations. Coeliac UK also advises keeping gluten-free ingredients separate during storage and preparation.
Who is this for?
Bakers following a measured recipe
If the recipe specifies an unsweetened drink, compare the exact carton’s sugars per 100 ml before substituting an original variant. Alpro UK lists 2.5 g sugars per 100 ml for Alpro Soya Original.
Dairy-free bakers considering soya
Coeliac UK’s Victoria sponge recipe allows dairy-free soya as an alternative to milk. Check the other cake ingredients separately, and do not use soya drink for someone with a soya allergy.
What should you check before buying?
Start with the carton’s gluten-free wording, then match the drink to the recipe and the people who will eat the cake.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free claim | Look for an explicit claim on the current carton. The Food Standards Agency states that gluten free means no more than 20 mg/kg gluten in the food as sold; a dairy-free or unsweetened description is a different check. | I need the drink itself to carry a clear gluten-free claim before using it in a strict gluten-free bake. |
| Recipe sweetness | Check whether the recipe specifies unsweetened soya drink and compare sugars per 100 ml on the exact carton. Alpro UK lists 2.5 g per 100 ml for Alpro Soya Original. | If the recipe already sets the sugar quantity, I want to know what the drink contributes before swapping variants. |
| Whole-cake ingredients | Check flour, baking powder, fillings and decorations separately. Coeliac UK advises keeping gluten-free ingredients apart during storage and preparation. | The finished cake needs more than a suitable milk substitute, especially when I also bake with gluten-containing flour. |
| Soya allergy | Read the exact carton’s ingredient and allergen information. The Food Standards Agency identifies soya as an allergen; gluten-free labelling does not mean soya-free. | If someone eating the cake has a soya allergy, I need a different ingredient and must check that alternative separately. |
Common baking mistakes to avoid
-
Assuming plant-based means gluten free
Dairy-free, vegan and unsweetened descriptions do not establish a gluten-free claim for the soya drink.
For a strict gluten-free bake, check the current carton for explicit gluten-free wording rather than relying on a retailer category alone.
-
Checking the drink but not the cake
Flour, baking powder, fillings and decorations are separate ingredients, while shared utensils and flour dust can introduce cross-contact.
Check each ingredient and follow Coeliac UK’s advice to keep gluten-free ingredients separate during storage and preparation.
-
Swapping original and unsweetened variants without checking
The variants can contribute different amounts of sugar. Alpro UK lists 2.5 g sugars per 100 ml for Alpro Soya Original.
Use the type specified by the recipe where possible, or compare the current carton’s nutrition panel before substituting it.
-
Confusing gluten free with soya free
A gluten-free claim does not remove soya, which the Food Standards Agency identifies as an allergen.
Check the allergen declaration for everyone eating the cake; if soya is unsuitable, check a different drink’s gluten-free and allergen information.

Questions about gluten-free cake baking
What does gluten free mean on a UK soya-drink label?
The Food Standards Agency states that a gluten-free claim means no more than 20 mg/kg gluten in the food as sold. Check that the claim applies to the exact drink you are buying; it does not cover the other ingredients in your cake.
Does gluten-free soya drink make the whole cake gluten free?
No. Check every other ingredient, including flour, baking powder, fillings and decorations. Coeliac UK also advises keeping gluten-free ingredients separate during storage and preparation to avoid cross-contact.
Should I use unsweetened or original soya drink for a cake?
Follow the recipe’s specified type where possible, particularly when its sugar quantity is measured around an unsweetened drink. Alpro UK lists 2.5 g sugars per 100 ml for Alpro Soya Original, so compare the exact carton’s nutrition panel before changing variants.
Is a gluten-free statement the same as the Crossed Grain Trademark?
No. A gluten-free statement is a claim for which the Food Standards Agency gives a limit of no more than 20 mg/kg gluten in the food as sold; the Crossed Grain Trademark is a separate mark. If you want that mark as well, look for it on the exact current carton rather than assuming that every gluten-free drink carries it.
Can I serve gluten-free soya cake to someone with a soya allergy?
Do not use soya drink for someone with a soya allergy: gluten-free labelling does not mean soya-free. The Food Standards Agency identifies soya as an allergen. Check any alternative drink’s gluten-free status and allergen information separately.
