For six ready-portioned servings, Tesco lists an 18-cake McVitie's snack pack; its 20-cake twin pack suits a smaller shared break, while the triple packs listed by Sainsbury's and Waitrose contain 33 and 30 cakes respectively. Check the count, opened-pack storage instructions and current allergen label on the pack you buy.
If everyone will serve themselves, compare the number of cakes in the pack with the number of people eating. Tesco lists a 20-cake McVitie's twin pack, while the triple packs listed by Waitrose and Sainsbury's contain 30 and 33 cakes respectively.
McVitie's 6 × 3 snack pack, listed by Tesco and Sainsbury's, provides six separate three-cake servings. That format avoids opening one shared pack to distribute the cakes.
When serving guests with food allergies or intolerances, read the ingredient and allergen information on the exact pack. Recipes and precautionary statements can differ between products.
Start with how the cakes will be served, then check the pack itself for the quantity and information your group needs.
| Priority | What to check | Your needs |
|---|---|---|
| Portion format | Check whether the cakes come in separate servings or a shared pack. Tesco and Sainsbury's list the McVitie's 6 × 3 snack pack as six three-cake servings. | I want to hand each guest a defined portion rather than put out an opened pack. |
| Cake count | Read the count on the exact listing or pack: Tesco lists 20 cakes in its McVitie's twin pack; Waitrose lists 30 and Sainsbury's lists 33 in their respective triple packs. Do not assume every triple pack has the same count. | There should be enough to share, but I do not want a larger pack than this tea break calls for. |
| Allergen information | Read the current ingredients, highlighted allergens and any precautionary statement on the specific pack. Marks & Spencer says its 250 g dark-chocolate Jaffa Cakes are not suitable for people with a nut or peanut allergy. | Before serving everyone, I need to check the particular product against my guests' requirements. |
| Leftovers | Consider how many cakes will remain after tea. Tesco's McVitie's twin-pack listing and Waitrose's triple-pack listing advise keeping the product in an airtight container once opened. | If we will eat the cakes over more than one break, I can plan where to keep the opened pack. |
| Availability | Check the selected shop or delivery location before relying on a particular format. M&S directs shoppers to their local Foodhall for product availability. | I need the chosen pack to be available for the tea break I am planning. |
Allergen information can differ by product. For example, M&S states that its 250 g dark-chocolate Jaffa Cakes are not suitable for people with a nut or peanut allergy.
Check the ingredients and allergen statement on the exact pack before serving guests.
The triple packs listed by Waitrose and Sainsbury's contain 30 and 33 cakes respectively, which may leave an opened pack after a smaller gathering.
Estimate how many cakes you will serve. If keeping leftovers, follow the pack's storage instructions; Waitrose advises an airtight container once its McVitie's triple pack is opened.
A product listing does not establish that the pack is available at your chosen shop or delivery location.
Check availability for your location before settling on a particular format.
