For an online grocery order, choose by the protein in each cake as well as per 100g: Sainsbury's lists Kallo lentil cakes at 26g per 100g but 1.8g per cake, while Ocado lists M&S barbecue rice cakes at 24.8g per 100g and 2.4g per cake. Kallo and Profusion suit shoppers open to a lentil-based cake; M&S is the rice-based option among these three. Check the delivered pack and any proposed substitute if ingredients or allergens determine your choice.
If you want a vegan, gluten-free cake, compare the dietary statement with the full ingredients and precautionary allergen wording. The listings for Kallo, M&S and Profusion describe dietary suitability, but that does not make their allergen information interchangeable.
A cake can be a convenient base for toppings, but check the portion you intend to eat. Sainsbury's lists 1.8g protein per Kallo cake, and Ocado lists 2.4g per M&S cake.
If protein content, ingredients or allergens determine your choice, review any proposed substitute rather than assuming another cake has the same recipe. Tesco and Sainsbury's describe substitution arrangements for online grocery orders.
Start with the portion and ingredient base, then check whether the product delivered still meets those requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per cake | Compare protein per 100g, protein per cake and cake weight. Sainsbury's lists Kallo at 26g per 100g and 1.8g per cake; Ocado lists M&S at 24.8g per 100g and 2.4g per 9.5g cake. | I want to know what the number means for the portion I will actually eat, not just for 100g of product. |
| Ingredient base | Read the ingredient list if rice matters to you. Marks & Spencer describes its barbecue cakes as a blend of wholegrain rice, buckwheat, pea protein and lentil flour; Kallo and Profusion are lentil-cake options. | A rice-based cake matters to me, or I am happy to use a lentil cake as a crisp snack or topping base. |
| Dietary details | Check the current dietary statement, ingredients and precautionary allergen wording together. The Kallo and Profusion grocery listings include may-contain sesame and soya information. | I need the delivered product to meet my dietary requirements, including any allergy restrictions. |
| Flavour and nutrition | Choose between a plain savoury cake and a seasoned one, then compare the fat and salt figures on the same per-100g basis. The M&S option has barbecue seasoning; Kallo offers a plainer base. | For toppings, I would prefer a plain base; for eating on its own, flavour may matter more to me. |
| Substitutions | Review the retailer's substitution setting and inspect any replacement's label. Tesco says alternatives may be offered when substitutions are allowed; Sainsbury's says it offers them where possible unless asked not to. | I would rather decline a different cake than receive one with unsuitable ingredients or a different protein amount. |
The cakes are small portions: Sainsbury's lists 1.8g protein per Kallo cake, while Ocado lists 2.4g per M&S cake.
Use the per-cake figure to work out the amount in the portion you plan to eat, alongside the per-100g figure when comparing products.
The Kallo and Profusion grocery listings describe vegan and gluten-free suitability but also include may-contain sesame and soya statements.
If an allergen matters to you, check the precautionary statement on the delivered pack, not just the dietary wording on the product page.
A replacement cake can differ in ingredients, allergens or protein content, even when it appears to serve the same purpose.
Set your substitution preference before ordering and check any replacement offered. Tesco and Sainsbury's both describe options for declining unsuitable substitutes.
Its Protein Packed Lentil Cakes are a plain savoury alternative when a rice base is not essential.
Its Barbecue High Protein Rice Cakes suit shoppers who want a seasoned, rice-based blend.
Its Organic Protein Lentil Cakes are an option when red-lentil ingredients matter more than a rice base.
The brand offers chocolate-covered protein rice cakes through its own store.
This Joybuy listing is for a Kallo lentil cake to consider if a plain, non-rice base suits your order.

A lentil-cake option for a savoury snack or topping base rather than a conventional rice cake. Check the current pack's protein per cake and precautionary allergen statement; the Joybuy product information flags milk, sesame and soya.
Check the amount per cake rather than relying on the front-of-pack wording. Sainsbury's lists 1.8g protein per Kallo lentil cake, and Ocado lists 2.4g per 9.5g M&S rice cake; the number of cakes you eat changes the portion total.
The Kallo, M&S and Profusion grocery listings describe vegan and gluten-free suitability, but check the exact delivered pack. The Kallo and Profusion listings also include may-contain sesame and soya statements, so dietary wording alone is not enough for an allergen decision.
M&S Barbecue High Protein Rice Cakes contain wholegrain rice alongside buckwheat, pea protein and lentil flour, according to Marks & Spencer. Kallo and Profusion are lentil-cake options, so choose the M&S product if a rice-based blend is important to you.
Check its ingredients, allergens and protein figures before accepting it. Sainsbury's says it may offer substitutes unless you ask otherwise; Tesco says alternatives may be offered when you allow substitutions. Their stated arrangements also allow an unsuitable substitute to be declined at delivery.
The pack identifies the product actually delivered, including its current ingredients, allergen statement and nutrition figures. Check it especially closely if the order was substituted or those details determined which cake you chose.
