For a coffee break built around one or two full-size rice cakes, plain or lightly salted options make it easy to count each cake: Kallo lists 27 kcal per cake, while Sainsbury's lists 29 kcal for its plain and lightly salted cakes. If you would rather carry one defined portion, the Snack a Jacks Salt & Vinegar mini bag lists 97 kcal for the whole 23 g bag. Compare the amount you expect to eat, not one cake with one bag, and check the current pack for nutrition and allergens.
Who is each format for?
The useful starting point is whether your coffee-break portion is a number of individual cakes or an entire snack bag.
Commuters counting individual cakes
If you usually take one or two full-size cakes, a per-cake figure lets you calculate that portion. Kallo lists 27 kcal for its Lightly Salted cake; Sainsbury's lists 29 kcal for each of its plain and lightly salted cakes. Count any topping separately.
Commuters carrying one snack bag
If taking a portion without selecting cakes from a larger pack matters more, the 23 g Snack a Jacks Salt & Vinegar mini bag is a different format. Sainsbury's lists 97 kcal for the whole bag, rather than per cake.
Shoppers checking dietary requirements
Check the exact pack rather than the rice-cake category. Kallo describes its Lightly Salted cakes as gluten free, but also warns that they may contain milk, sesame seeds and soya.
What should you check?
Choose the portion format first, then compare nutrition and ingredients for the exact product you would take with coffee.
Full-size plain or lightly salted cakes
Choose when: You want to decide how many individual cakes to have.
Bear in mind: A multi-cake pack does not define your coffee-break portion; toppings add to it.
Mini snack bag
Choose when: Carrying a single, defined bag matters more than choosing cakes individually.
Bear in mind: The bag's calorie figure covers all its contents, so it cannot be compared directly with one full-size cake.
| Priority | What to check | Your needs |
| Portion and calories |
Find out whether energy is stated per cake or per bag. Check how many cakes you plan to eat, or whether you will finish the bag. |
I usually have a couple of cakes with coffee, so a per-cake figure helps me count my portion. If I take one mini bag instead, I need its whole-bag figure. |
| Flavour and nutrition |
Compare calories, sugars and salt for the exact flavour on the same per-cake basis. Sainsbury's lists 42 kcal and 0.19 g salt per salt-and-vinegar rice-and-corn cake; Tesco lists 41 kcal and 2.7 g sugars per caramel-flavour cake. |
A flavoured cake might suit my coffee break, but I would check its own label rather than use the figures for a plain cake. |
| Ingredients and allergens |
Read the current ingredients and allergen statement for the exact pack. Kallo labels its Lightly Salted cakes gluten free but warns that they may contain milk, sesame seeds and soya. |
If I need to avoid a particular ingredient or allergen, the claim on the front of the pack is not my whole check. |
Common buying mistakes
-
Comparing one cake with an entire mini bag
Kallo's 27 kcal figure applies to one Lightly Salted cake; Sainsbury's 97 kcal figure for the Snack a Jacks mini snack applies to a whole 23 g bag. They describe different amounts of food.
Compare the totals for the number of cakes you expect to eat or the bag you expect to finish.
-
Assuming the flavour makes no difference
Recipes vary. Sainsbury's lists 29 kcal and 0.02 g salt per lightly salted wholegrain cake, but 42 kcal and 0.19 g salt per salt-and-vinegar rice-and-corn cake.
Use the calorie, sugars and salt figures for the flavour and serving size you are buying.
-
Using a gluten-free claim as a complete allergen check
Kallo labels its Lightly Salted cakes gluten free while warning that they may contain milk, sesame seeds and soya. One dietary claim does not answer a different allergen question.
Read the ingredients and allergen statement on the current pack for the substances you need to avoid.
-
Relying on an older online nutrition listing
Tesco advises shoppers to read the product label because food products can be reformulated. A saved calorie or ingredient figure may not describe the pack in hand.
Check the received pack's nutrition, ingredients, allergens and portion size before relying on an online figure.
Brand and range references
These examples show why the exact product and serving unit matter more than the brand name alone.
Kallo
Kallo's Lightly Salted cake is a full-size option with a stated per-cake figure.
- Kallo states 27 kcal per Lightly Salted cake and labels it gluten free.
- The same product carries a may-contain warning for milk, sesame seeds and soya.
Sainsbury's
Its plain, lightly salted and salt-and-vinegar products illustrate the need to compare recipes separately.
- Sainsbury's lists 29 kcal per cake for both its plain and lightly salted 135 g products.
- Its salt-and-vinegar rice-and-corn cake has a different stated figure: 42 kcal and 0.19 g salt per cake.
Snack a Jacks
The Salt & Vinegar mini snack offers a bagged portion rather than a sleeve of full-size cakes.
- Sainsbury's lists 97 kcal for the entire 23 g mini bag.
- That per-bag figure is not directly equivalent to a full-size rice cake's per-cake figure.
Tesco
Tesco separates its rice-cake range into plain and salted, flavoured, and chocolate and sweet products.
- Tesco lists 41 kcal and 2.7 g sugars per caramel-flavour cake, giving a specific figure to compare with other flavours.
- Tesco advises reading the product label because formulations can change.
M&S
M&S describes its Lightly Salted cakes as made from puffed wholegrain brown rice and suggests eating them alone or with toppings.
- Its range includes lightly salted and other rice-cake recipes.
- Check the nutrition and ingredients of the particular M&S pack, especially if adding a topping to your coffee-break portion.

Questions about rice cakes
Should I compare calories per cake or per bag?
Use the figure for the amount you expect to eat. Kallo lists 27 kcal per Lightly Salted cake and Sainsbury's lists 29 kcal per plain or lightly salted cake, whereas Sainsbury's lists 97 kcal for the entire 23 g Snack a Jacks Salt & Vinegar mini bag. One cake and one bag are different portions.
Do flavoured rice cakes have the same nutrition as plain ones?
No single figure applies to every flavour. Sainsbury's lists 42 kcal and 0.19 g salt per salt-and-vinegar rice-and-corn cake; Tesco lists 41 kcal and 2.7 g sugars per caramel-flavour cake. Read the exact flavour's nutrition panel.
Does gluten free mean a rice cake is suitable for every allergy?
No. Kallo labels its Lightly Salted cake gluten free but warns that it may contain milk, sesame seeds and soya. Check the current pack's ingredients and allergen statement for your particular requirement.
Do toppings count in the coffee-break portion?
Yes. A per-cake calorie figure describes the cake, not a spread or other topping added to it. If you add one, check its portion and nutrition separately when comparing your snack options.
How should I keep an opened pack for later commutes?
Follow the instructions on the pack you buy. Sainsbury's listing for Kallo Organic Lightly Salted Rice Cakes says to keep the cakes in an airtight container after opening and consume them within 14 days.
