For a protein-focused afternoon snack, compare protein per 100g and per cake rather than assuming any rice cake will meet that aim. Marks & Spencer lists 24.8g per 100g for its Barbecue High Protein Rice Cakes; Kallo lists 26g per 100g for its Protein Packed Lentil Cakes, which are a lentil-based alternative rather than a conventional rice cake. If you prefer a plain rice cake, consider what topping you would add and check the protein in the portion you plan to eat.
Who these options suit
Snackers comparing protein per portion
If you want the cake itself to contribute protein, check both the per-100g declaration and the amount per cake. Marks & Spencer lists 24.8g protein per 100g for its Barbecue High Protein Rice Cakes; Kallo lists 26g per 100g and 1.8g per cake for its Protein Packed Lentil Cakes.
Shoppers who prefer a plain rice-cake base
A plain or lightly salted cake leaves you free to choose a topping. Tesco lists 0.6g protein per cake for Kallo Lightly Salted Wholegrain Rice Cakes, so check the whole snack—not just the cake—if protein is your reason for choosing it.
Shoppers checking dietary labels and allergens
Marks & Spencer labels its Barbecue High Protein Rice Cakes vegan, vegetarian and gluten free. Kallo labels its Protein Packed Lentil Cakes vegan and gluten free, but the lentil cakes may contain sesame seed and soya. Check the current pack against your requirements.
What to check before choosing
Start with the type of cake you want, then compare protein on the same per-100g basis and check the amount in the portion you would actually eat.
| Priority | What to check | Your needs |
| Protein per portion |
Compare protein per 100g, then per cake or planned portion. Marks & Spencer lists 24.8g per 100g for its barbecue rice cakes; Kallo lists 26g per 100g and 1.8g per cake for its protein lentil cakes. |
If I am choosing the snack for its protein, I want to know what the amount I eat will provide—not just what the front of the pack says. |
| Type of cake |
Read the product name and ingredients. Marks & Spencer’s protein-focused rice cakes contain wholegrain rice, buckwheat, pea protein and lentil flour; Kallo’s protein-focused option is a lentil cake. |
I would rather keep a rice-cake base, or I am happy to choose a lentil-based alternative for a different ingredient profile. |
| Plain or flavoured |
Check the flavour and the nutrition declaration for the specific product. Tesco lists 0.6g protein per cake for Kallo’s lightly salted wholegrain rice cakes; Sainsbury’s lists 0.8g per snack for Snack a Jacks Jumbo Caramel. |
A plain cake gives me a base for a topping, while a ready-flavoured cake suits me when I do not plan to add one. |
| Dietary suitability |
Check the current dietary labels, ingredients and allergen statement. Kallo Protein Packed Lentil Cakes may contain sesame seed and soya; Tesco says Kallo’s plain wholegrain rice cakes may contain milk, sesame and soya. |
If I need to avoid an ingredient or heed a may-contain warning, the label on the pack matters more than the product’s general description. |
Common buying mistakes
-
Taking calorie or fibre wording as a protein comparison
Sainsbury’s lists Snack a Jacks Jumbo Caramel at 50 kcal and 0.8g protein per snack. Tesco lists 0.6g protein per cake for Kallo’s lightly salted wholegrain rice cakes. Neither figure tells you what another product provides.
Compare protein per 100g across products, then check the amount per cake or serving you intend to eat.
-
Assuming every cake in the aisle is a rice cake
Kallo Protein Packed Lentil Cakes offer a different ingredient base from conventional rice cakes. That distinction matters if you specifically want a rice-based snack.
Read the product name and ingredients before choosing between a rice cake and a lentil-based alternative.
-
Skipping allergen checks because of a dietary label
Kallo Protein Packed Lentil Cakes are labelled vegan and gluten free, but may contain sesame seed and soya. Tesco also lists may-contain warnings for milk, sesame and soya on Kallo’s plain wholegrain rice cakes.
Check the current pack’s ingredient and allergen statements for the exact product you buy.

Check the amount per cake before relying on it for protein. Tesco lists 0.6g per cake for Kallo Lightly Salted Wholegrain Rice Cakes, while Marks & Spencer lists 9.6g per 100g for its Lightly Salted Rice Cakes. If you prefer a plain cake, include any topping when assessing the whole snack.

Do vegan or gluten-free labels replace an allergen check?
