Choose a six-by-three snack pack if you want to open some Jaffa Cakes for decorating and keep separate packets for later lunchboxes. A larger pack makes sense when most cakes will be used together, provided you can follow its instructions for storing leftovers. Check the cake count, inner wrapping and current allergen labels for both the cakes and any toppings.
Who is choosing?
Families decorating cakes together
You need enough ready-made cakes for the activity and a plan for anything left over. Children can take on manageable preparation tasks, with support where needed, as described in guidance from Solihull Children’s Occupational Therapy Service.
Families planning later lunchboxes
You want to know whether unused cakes can stay in separate packets or whether you will need to store and portion them yourself. The cakes are a sweet extra, rather than the main lunchbox item.
Families checking group allergens
When several children will share the finished cakes, check the current label on the exact pack and on every decorating ingredient. Similar-looking products can carry different ingredient and precautionary-allergen information.
What should you check?
Decide how many cakes you will decorate now, then check which portions can remain unopened for later.
| Priority | What to check | Your needs |
| Separate portions |
Look for the number of inner packets, not just “multi-pack”. The McVitie’s six-by-three snack format has six three-cake packets, according to Tesco and Sainsbury’s listings. |
I want to open only the packets needed for decorating and keep others for later lunchboxes. |
| Quantity and storage |
Count the cakes needed for the activity and follow the chosen pack’s opening instructions. Tesco lists 33 cakes in its McVitie’s 363g triple pack and specifies airtight storage once opened; its own-label 2 × 150g twin pack says to consume opened cakes within two days. |
Most of our cakes will be used together, and I can store any leftovers as the pack directs. |
| Allergen labels |
Read the current ingredients and precautionary statements on the exact cake pack and every topping. Do not assume another retailer’s apparently matching listing describes the pack in your hands. |
Several children may eat the finished cakes, so I need to check every ingredient against their known allergies before decorating. |
| Lunchbox portions |
Check the serving on the pack rather than treating one packet as one cake. Sainsbury’s lists 16.3g sugars per three-cake serving for its McVitie’s 6 × 3 snack pack. NHS Healthier Families suggests foods such as bread, rice, pasta or potatoes for the main lunchbox item. |
I want to plan the whole lunchbox, with any Jaffa Cakes as an extra rather than the main item. |
Common pack mistakes
-
Assuming every multi-pack has lunchbox-sized packets
The McVitie’s six-by-three snack format specifies separate portions; a larger or mini format does not necessarily have the same inner wrapping.
Check the inner-pack description and decide how many packets the children will open during the activity.
-
Treating similar-looking packs as having identical allergen information
Retailer descriptions of apparently matching snack packs can differ, so a listing cannot settle which ingredients or precautionary warnings appear on the pack being served.
Use the current physical label for allergy checks, and check decorating ingredients separately.
Brand and own-label references
McVitie’s
Tesco and Sainsbury’s list a six-by-three snack format, while Tesco lists a separate 33-cake triple pack. These named packs offer different ways to divide cakes between an activity and later use.
- The six-by-three format provides separate three-cake packets.
- Tesco instructs shoppers to store its listed 363g triple pack airtight after opening.
Tesco
Tesco lists an own-label orange Jaffa Cake twin pack containing 2 × 150g, a format to consider when cakes will be shared rather than kept as confirmed individual lunchbox packets.
- The listing identifies two 150g packs.
- Tesco says to consume the cakes within two days of opening and lists a “may contain milk” warning.
Sainsbury’s
Sainsbury’s lists an own-label 24-cake pack, another quantity to consider for a shared decorating activity.
- The listing identifies 24 cakes.
- It advises airtight storage after opening; the 24-cake count does not establish separate inner portions.
Waitrose
Waitrose lists 125g mini Jaffa Cakes for activities where smaller pieces are wanted, rather than a confirmed individually portioned multi-pack.
- The named product is a mini format.
- Waitrose specifies airtight storage after opening and lists a “may contain milk” warning.
M&S
M&S lists 100g mini Jaffa Cakes, another small-piece format for decorating.
- The named product is a 100g mini format.
- M&S marks this product unsuitable for people with nut or peanut allergies and directs shoppers to the current label because recipes can change.

McVitie’s 80 Jaffa Cakes 1.07kg

Questions about decorating and storage
Do children need to bake Jaffa Cakes before decorating them?
No. The listed cakes are ready-made, so children can decorate them without baking the cakes first. Break preparation into manageable tasks, provide support where needed and check the labels on both the cakes and the toppings.
How should we keep cakes left over from decorating?
Follow the instructions on the chosen pack. Tesco specifies airtight storage for its listed McVitie’s triple pack and says to consume its own-label twin pack within two days of opening; Waitrose also specifies airtight storage for its minis. Cakes in an unopened inner snack packet need not be opened for the activity.
Can a child with a food allergy have these Jaffa Cakes?
The category name cannot answer that question. Check the current ingredients and precautionary-allergen information on the exact pack against the child’s known allergies, then check every topping separately. Do not substitute the label details from a similar-looking product.
What should I check before putting decorated cakes in a nursery lunchbox?
Check the nursery’s food policy and the labels of the cakes and toppings. NHS guidance advises families to check nursery food policies and to tell the nursery or childminder about a child’s food allergy; keeping the original packaging makes its ingredient information available when preparing the lunchbox.
