People tracking their packed-lunch portions
A calorie figure per cake or sealed bag makes it easier to count the portion you intend to pack than a per-100g figure alone.
Who is this choice for?
People adding their own toppings
Plain rice cakes provide a base for sweet or savoury toppings. Include the topping when working out the lunch total, and pack it separately if needed.
Commuters carrying a ready-portioned snack
A sealed mini bag provides a defined serving that can go straight into a work bag. Check its per-bag label rather than comparing it with a single cake.
What should you check?
Decide whether you are packing individual cakes, topped cakes or a whole snack bag before comparing labels.
| Priority | What to check | Your needs |
|---|---|---|
| Serving size | Read whether kcal refers to one cake, one snack or a whole bag. Compare the same portion size, or calculate the portion you will actually eat. | I want to know what my packed portion adds up to, rather than compare one cake with an entire bag. |
| Toppings | Check the plain cake's label, then account separately for the amount and ingredients of any topping. | A plain cake suits me as a base, but the topping is part of my lunch too. |
| Pack format | Check the weight and kcal per sealed bag for mini packs. For jumbo cakes, look for the stated per-cake or per-snack figure instead. | On days when I need something ready to pack, a sealed portion may be simpler than bringing separate cakes and toppings. |
| Ingredients and allergens | Read the exact pack's ingredient and allergen statements. Dietary wording such as vegan or gluten free does not settle every allergy question. | If I have a food allergy or dietary requirement, I need the statement for the particular product I am buying. |
| Other label details | Use the nutrition panel to compare fat, saturates, sugars and salt on a consistent basis. GOV.UK explains that traffic-light labels can help with an at-a-glance comparison. | Calories matter to my choice, but I also want to see how flavoured and plain options differ on the label. |
Common buying mistakes
-
Comparing a bag with a single cake
A per-bag calorie figure covers the bag's contents, while a per-cake figure covers one cake. Those figures do not describe the same portion.
Choose the amount you plan to eat, then compare labels on that basis.
-
Counting the cake but not its topping
The calorie and allergen information for a plain cake does not include anything added to it.
Check and portion the topping separately when planning a topped rice-cake lunch.
-
Relying on a dietary claim alone
Sainsbury's says its own-label plain and lightly salted cakes are prepared to a vegan recipe but are not suitable for customers with a milk allergy because of manufacturing methods. Its Kallo Organic Lightly Salted listing notes possible milk, sesame and soya cross-contact.
Read the current allergen statement on the exact pack before choosing it for an allergy.
-
Leaving an opened pack unsealed
Opened cakes need suitable storage to retain their texture; M&S advises keeping its lightly salted cakes in an airtight container after opening.
Follow the storage instructions on your pack and seal the remaining cakes after packing lunch.

Kallo
Kallo has a plain-style rice cake and a separate lentil-and-pea veggie cake for shoppers considering different snack formats.
- Sainsbury's lists Organic Lightly Salted Wholegrain Rice Cakes at 27 kcal per cake and Sweet Chilli Lentil & Pea Veggie Cakes at 38 kcal per cake.
- The veggie cake is not a plain rice cake. The Organic Lightly Salted listing notes possible milk, sesame and soya cross-contact.
Snack a Jacks
Its flavoured range includes individual jumbo cakes and sealed mini bags.
- Sainsbury's lists a Jumbo Caramel cake at 50 kcal per snack and a 19 g Sour Cream & Chive mini bag at 78 kcal per bag.
- One jumbo cake and one mini bag are different serving units; check the portion before comparing their figures.
Sainsbury's
Its own-label range includes plain and lightly salted rice cakes.
- Sainsbury's lists both 135 g products at 29 kcal per cake; the plain cake has less than 0.01 g salt per cake and the lightly salted cake has 0.02 g.
- Both listings say the cakes are not suitable for customers with a milk allergy because of manufacturing methods.
Tesco
Tesco describes its Lightly Salted Rice Cakes as made with puffed brown rice.
- The lightly salted format offers a savoury option to consider for a packed lunch.
- Check the pack's per-cake nutrition figure before comparing it with products labelled per cake.
Asda
Asda lists both an own-label slightly salted rice cake and Kallo Organic Lightly Salted Wholegrain Rice Cakes.
- Asda's Kallo listing states 27 kcal per rice cake.
- Check the own-label pack's per-cake figure separately; the Kallo figure does not describe Asda's own-label cakes.
M&S
M&S describes its lightly salted wholegrain brown-rice cakes as a base for spreads and toppings.
- Marks & Spencer lists 386 kcal and 3.4 g fibre per 100 g, along with advice to keep opened cakes airtight.
- For a per-cake comparison, check the weight or per-cake information on the pack rather than treating the per-100g figure as one serving.

A sweet chilli rice-cracker alternative rather than an individual rice cake. Its stated calorie serving is 25 g, not one cracker; use the portion you pack when comparing it with per-cake options.
Questions about rice cakes for work
How do I compare calories between rice cakes and mini bags?
Compare the portion you plan to eat, not just the numbers printed on the front. Sainsbury's lists examples at 27 or 29 kcal per plain cake, while its Snack a Jacks Sour Cream & Chive mini bag is 78 kcal for the whole 19 g bag.
Does a low-calorie rice cake make the whole lunch low calorie?
Not necessarily: a per-cake figure does not include toppings or other lunch items. If you use plain cakes as a base, check the topping's portion and label separately.
When is a sealed multipack bag useful?
Choose one when you want a defined portion that is ready to put in a work bag. For example, Sainsbury's lists each Snack a Jacks Sour Cream & Chive multipack bag as 19 g and 78 kcal; compare that whole-bag figure with the portion you would pack from another format.
Does vegan or gluten-free wording rule out milk cross-contact?
No. Sainsbury's says its plain and lightly salted own-label cakes are prepared to a vegan recipe but are not suitable for customers with a milk allergy because of manufacturing methods. Its Kallo Organic Lightly Salted listing notes possible milk, sesame and soya cross-contact. Read the current statement on the exact pack.
How should I keep opened rice cakes for packed lunches?
Follow the storage instructions on the pack and close it after taking out your lunch portion. Marks & Spencer advises keeping its lightly salted rice cakes in an airtight container once opened.
