Having a cake sale, whether it’s in school as a PTA fundraiser or in the office to celebrate a birthday, sounds simple in theory. In practice, allergies and dietary requirements mean it needs a little more care than choosing a recipe and swapping a few ingredients.
Important allergen note: a home-baked cake should not be described as “allergen-free”, “safe for everyone” or suitable for a person with a particular food allergy simply because certain ingredients have been left out. Ingredient labels, manufacturing warnings, utensils, surfaces and cross-contact all matter. For a school, workplace or organised event, follow the organiser's allergen policy and the Food Standards Agency's current guidance.
Ingredient substitutions are recipe choices, not allergy guarantees
The substitutions below can be useful when developing a cake for a dietary preference, but they do not by themselves make a finished bake safe for somebody with an allergy. Always check the exact ingredients you use.
Butter and oil
Instead of converting a butter recipe by guesswork, start with a recipe designed for oil if that is the ingredient you want to use. Butter and oil contain different amounts of water and fat and behave differently in baking. Our Hero Sponge is an example of an oil-based sponge.
Plant drinks
Oat, soya, almond and other plant drinks have different formulations and allergen profiles. Do not assume a plant drink is suitable for a particular allergy from its name alone; read the label on the exact product you are using and follow a tested recipe.
Egg substitutes
Eggs perform several jobs in a cake, including binding, structure and aeration. Banana, apple purée and commercial egg replacers can all change texture and flavour, so use a recipe developed and tested for that substitute rather than treating it as a universal one-for-one swap.
Gluten-free baking
Gluten-free flour blends vary and often need different hydration or binders. If you are baking for someone with coeliac disease or a wheat allergy, the ingredient list is only part of the picture: cross-contact and the preparation environment matter too.
About our school-cake recipe
We have a step-by-step vanilla sponge recipe that avoids several common ingredients. Treat it as a recipe idea, not as a blanket promise that the finished cake is safe for every person or every allergy. Check every ingredient and your preparation environment for the people you are serving.
What Anges de Sucre can and cannot offer
We are not able to make allergen-free cakes on our premises because we handle ingredients including wheat, egg, milk, nuts, peanuts and soya. That is why we do not present our celebration cakes as suitable for customers who need an allergen-free preparation environment.
If you simply want to browse our recipe ideas, you can see our recipe collection. If you are buying food for someone with an allergy, please use the current ingredient and allergen information for the exact product and contact the food business directly if anything is unclear.
