Hosts feeding a group
A countable sharing pack lets you plan against your guest list. Morrisons lists 30 cakes in a McVitie’s 3 × 10 pack; Sainsbury’s lists 24 in its own-label pack.
Who is each format for?
Hosts planning individual servings
McVitie’s lists six snack packs of three cakes, giving you separate portions and 18 cakes in total.
Hosts accommodating food allergies
Ask guests or their carers about requirements, then check the packaging of the product you will serve. Ingredient and precautionary-allergen statements differ between the packs listed by Morrisons, Sainsbury’s, Ocado and Waitrose.
What should you check before choosing?
Work out the cake count first, then decide whether a shared plate or separate portions fit the event. Check the exact pack again before ordering and serving.
| Priority | What to check | Your needs |
|---|---|---|
| Cake count | Multiply your planned cakes per guest by the guest count. Morrisons lists 30 cakes in its McVitie’s 3 × 10 pack; Sainsbury’s lists 24 in a 282g pack. | I want enough cakes for the servings I have planned, rather than relying on the words “family pack”. |
| Serving format | Check whether the cakes are for a shared plate or packed as separate portions. McVitie’s lists six snack packs of three cakes: 18 cakes altogether. | Separate packs would make it easier to hand out the portions I have planned; a sharing pack would suit a table where guests help themselves. |
| Ingredients | Read the supplied pack’s ingredients and allergy statements. Morrisons lists egg, milk, soya and wheat for its McVitie’s 330g triple pack; Ocado lists its M&S 125g pack as unsuitable for people with a nut or peanut allergy. | Guests need to be able to check the information for the cakes actually served. GOV.UK recommends keeping prepacked-food packaging available at community events for people with food hypersensitivities. |
| Pack type | Compare cake count with pack weight; they are not the same measure. Ocado lists the M&S 125g pack as serving 11, while Waitrose lists five servings for its 125g mini Jaffa Cakes bag without giving an individual cake count. | I may prefer smaller pieces or a different orange-and-chocolate cake, but I cannot plan individual cakes from a serving or weight figure alone. |
| Availability | Check the current listing and the delivered pack before committing to a serving plan. Sainsbury’s 24-cake listing was marked out of stock when consulted. | If I am counting on a particular pack, I need to know I can obtain that format in time for the party. |
Party-shopping pitfalls
-
Assuming every multipack has the same cake count
The documented formats range from 18 cakes in McVitie’s six snack packs to 30 in the 3 × 10 sharing pack listed by Morrisons.
Use the labelled count and your planned servings to decide how many packs to order.
-
Assuming different packs have the same allergy information
The listed products have different ingredient and precautionary-allergen statements, so a familiar product name is not enough to establish suitability for a guest.
Check the pack supplied and keep its packaging available when serving. GOV.UK recommends retaining prepacked-food packaging at community events so guests can check ingredients they avoid.
-
Planning around a pack that is unavailable
Sainsbury’s listing for its 24-cake pack was marked out of stock when consulted, which could leave a gap in a plan based on that count.
Recheck availability and the cake count before ordering; check any substituted pack’s ingredients before serving it.
Brand and own-label references
These examples show why pack counts, portion formats and allergy statements need checking product by product; they do not establish which products a retailer currently has available.
McVitie’s
Original Jaffa Cakes are documented in a 3 × 10 sharing pack and six snack packs of three.
- Morrisons lists 30 cakes for the 330g sharing pack; McVitie’s lists 18 across the separate snack packs.
- Morrisons lists egg, milk, soya and wheat for the 330g triple pack. Check the supplied pack rather than applying one format’s label to another.
Sainsbury’s
Its documented own-label orange Jaffa Cakes come in a 24-cake, 282g pack.
- The listed cake count can be used for party quantity planning.
- The listing was marked out of stock when consulted and says the product is unsuitable for customers with a milk allergy due to manufacturing methods.
M&S
Ocado lists a 125g dark-chocolate orange Jaffa Cakes pack serving 11.
- Its listed serving figure offers a way to plan this smaller pack.
- The listing says the pack is unsuitable for people with a nut or peanut allergy.
Waitrose
Waitrose lists mini Jaffa Cakes in a 125g bag with five servings.
- The mini format offers a different piece size from a standard sharing pack.
- Five servings is not an individual cake count. The listing also says the product may contain milk.
Asda
An Asda own-label Jaffa Cake appeared in a Daily Express writer’s five-product taste comparison in September 2026.
- The writer preferred the Asda product tasted in that comparison; this was a personal flavour judgement, not a finding about every Asda pack.
- Check the ingredients and cake count of the particular pack you intend to serve.
Tesco
Tesco lists an own-label orange Jaffa Cake twin pack of 2 × 150g alongside McVitie’s multipacks.
- The twin-pack weight is stated in Tesco’s listing.
- Confirm its individual cake count and ingredient declaration on the particular pack before using it for party planning.

Questions about serving Jaffa Cakes
How many Jaffa Cakes should I buy for a birthday party?
Choose how many cakes you plan to offer each guest, multiply by your guest count and compare the result with the pack label. Morrisons lists 30 in its McVitie’s 3 × 10 pack, Sainsbury’s lists 24 in its own-label pack, and McVitie’s lists 18 across six snack packs; none of those counts sets a serving size for every party.
Do Jaffa Cakes need preparing before guests arrive?
The listed cakes can be served from the pack. Ocado’s McVitie’s triple-pack listing says to store it in a cool, dry place and use an airtight container after opening; check the pack’s best-before date as you plan when to serve it.
What if a guest has a food allergy?
Ask about the guest’s requirements and check the actual pack before serving it. Morrisons lists egg, milk, soya and wheat for its McVitie’s 330g triple pack, while Ocado lists its M&S 125g pack as unsuitable for people with a nut or peanut allergy. GOV.UK recommends keeping prepacked-food packaging available at community events so guests can check ingredients they avoid.
Do HFSS advertising rules stop me serving Jaffa Cakes at a birthday party?
The UK advertising restrictions described by the Department of Health and Social Care concern specified TV and paid-for online advertising of products within their scope, not serving food at a private party; they do not establish the classification of a particular Jaffa Cake pack. If the event is at a school or childcare setting, ask the organiser about that setting’s food and allergy procedures before buying.
