Shoppers comparing calories per cake
Look for a product-specific gluten-free claim and a per-cake energy figure, rather than assuming that every rice cake has the same portion size.
Who is this for?
Shoppers making topped snacks
A plain gluten-free cake provides a base for toppings. Count the cakes and toppings separately when comparing the snack you plan to eat.
Shoppers checking other allergens
A gluten-free claim does not address every allergy. Read the full pack label for ingredients and precautionary statements about milk, sesame or soya.
What should you check?
Confirm the exact product’s gluten-free status, then compare energy on a portion basis that matches how you will eat it.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free status | Check the current pack for an explicit gluten-free claim for the exact product and flavour, or seek manufacturer confirmation. Read its ingredients and allergen information too. | I want to know the finished product suits coeliac shopping, not just that it contains rice. In Coeliac UK’s 2025 Shopping Habits survey, 74.7% of 3,785 responding members said they trusted its Crossed Grain Trademark more than a gluten-free statement; that preference does not make the trademark a requirement for every gluten-free product. |
| Amount eaten | Kallo lists 18 kcal per Organic Unsalted Thin and 27 kcal per Lightly Salted cake; Tesco Groceries lists 30 kcal per Free From cake. Tesco Groceries gives Nature’s Store as 38 kcal per approximately 10 g portion, which is not explicitly one cake. | If I am eating several cakes or adding toppings, I need the energy for that whole snack. A figure per 100 g alone will not tell me the energy in one cake. |
| Other allergens | Read both the ingredients and any “may contain” statement on the current pack. Kallo and Tesco plain rice-cake listings include precautionary information about milk, sesame or soya. | Gluten-free status is only one of my checks if I also need to avoid milk, sesame or soya. |
| Flavour and coating | Check nutrition for the exact flavour and the stated serving size. Marks & Spencer lists its gluten-free Dark Chocolate Rice Cakes at 478 kcal and 21.6 g sugars per 100 g, but does not give a per-cake energy figure in the supplied listing. | For a chocolate-coated snack, I would compare the amount I intend to eat rather than assume its energy matches a plain cake. |
Common buying mistakes
-
Assuming rice-based means gluten free
Rice in the ingredient list does not, by itself, establish the gluten-free status of the finished snack.
Check the current pack for a claim covering the exact product and flavour, or ask the manufacturer to confirm suitability.
-
Comparing figures for different portion sizes
Manufacturer and retailer figures here range from calories per thin or cake to calories per approximately 10 g portion. Those amounts cannot automatically be treated as equivalent.
Compare the number of cakes you expect to eat, then include any toppings or coatings in the snack total.
-
Overlooking other allergen warnings
Some gluten-free plain cakes carry precautionary milk, sesame or soya statements; a coating can introduce further ingredients.
Check the full label against any separate allergy requirements rather than relying on the gluten-free claim alone.
-
Relying on an older product listing
Ingredients and allergen information can change, so an earlier online description may not match the pack in hand.
Use listings to narrow your choices, then check the current pack before eating.
Brand and range references
Kallo
Kallo lists gluten-free Organic Unsalted Thins at 18 kcal per thin and lightly salted cakes at 27 kcal per cake.
- The stated per-cake figures make it possible to compare these named varieties.
- Kallo’s lightly salted product information includes precautionary milk, sesame and soya advice; check the exact pack.
Tesco Free From
Tesco Groceries lists Free From Wholegrain Rice Cakes as wheat and gluten free, at 30 kcal per cake.
- The listing gives a per-cake figure for this specific wholegrain product.
- Its allergen information says it may contain sesame seeds, soya and milk; confirm the current pack.
Nature’s Store
Tesco Groceries lists Nature’s Store Wholegrain Rice Cakes as gluten free, with 38 kcal per approximately 10 g portion.
- The listed ingredient is wholegrain brown rice.
- The stated portion is not explicitly one cake, and the listing says it may contain sesame seeds and soya.
M&S
The M&S rice-cake range includes plain and coated formats. Its Dark Chocolate Rice Cakes are labelled gluten free.
- Marks & Spencer gives nutrition for the named dark chocolate product, including 478 kcal per 100 g.
- That per-100 g figure is not a per-cake comparison with the plain products; check the exact product’s allergens as well.
Snack a Jacks
Snack a Jacks publishes per-cake energy figures for several Jumbo flavours, including 51 kcal for Caramel.
- Flavour-specific figures help with portion comparisons.
- For coeliac shopping, check the exact flavour’s current pack for a gluten-free claim rather than applying one flavour’s information to the range.

Frequently asked questions
Are rice cakes suitable for coeliac shopping just because they contain rice?
No. Check for a current gluten-free claim or seek manufacturer confirmation for the exact finished product; the rice ingredient alone does not establish its suitability.
How many calories are in Kallo Organic Unsalted Thins?
Kallo lists 18 kcal per Organic Unsalted Thin and labels that product gluten free. Compare the number of thins you intend to eat, including any toppings, rather than treating 18 kcal as the total for a topped snack.
Should I compare rice cakes per 100 g or per cake?
For the snack you plan to eat, use calories per cake where stated, or the defined portion if no per-cake figure is given. A per-100 g figure can help compare equal weights, but it does not establish the energy in an individual cake.
Do gluten-free rice cakes still need an allergen check?
Yes. Gluten-free status does not cover every allergen: Kallo and Tesco plain rice-cake listings include precautionary statements about milk, sesame or soya. Read the current pack if any of those ingredients matter to you.
Can I compare chocolate-coated rice cakes directly with plain cakes?
Compare the amount you will eat, not the product category alone. Marks & Spencer lists its gluten-free Dark Chocolate Rice Cakes at 478 kcal per 100 g, without a per-cake energy figure in the supplied listing, so that figure cannot be directly ranked against a plain cake’s per-cake value.
