Afternoon-tea hosts
Pack counts and piece sizes matter when you are serving a group. Check how many cakes you intend to offer each guest, as well as any relevant allergies.
Who is choosing?
Chocolate-first snackers
A dark-chocolate top on a round cake and a fully milk-chocolate-coated bar are different formats. Choose the coverage and chocolate type you want with tea.
Allergy-conscious shoppers
Check the ingredients and precautionary statements on the particular pack you plan to serve. Similar-looking Jaffa cakes can carry different allergen information.
What should you compare?
Start with the cake format, then check the pack’s count or serving basis and the information needed for your guests.
| Priority | What to check | Your needs |
|---|---|---|
| Chocolate and format | Check whether chocolate tops a round cake or fully coats a bar, and whether it is dark or milk chocolate. Marks & Spencer describes its Jaffa Cake Bars as fully coated in milk chocolate. | I want a round orange cake with a chocolate top, or I would rather serve a fully coated bar. |
| Pieces for guests | Use a stated cake count where available: the McVitie's Original 110g pack listed by Asda contains 10 cakes. Asda suggests 12 servings for its own-label 150g pack; Waitrose’s 25g mini-cake nutrition serving is not a piece count. | For a group, I need to know how many pieces I can put out, not just the pack weight. |
| Allergens | Read the purchased pack’s ingredients and precautionary statements. Asda lists milk among the ingredients of the McVitie's Original 110g pack, while its own-label 150g pack carries a may-contain-milk warning. Marks & Spencer labels its 250g dark-chocolate cakes unsuitable for people with nut or peanut allergies. | One of my guests has an allergy, so the information for the exact cake I serve matters. |
| Storage and date | Follow the purchased pack’s storage directions, including instructions for opened cakes. GOV.UK distinguishes best-before dates, which concern quality, from use-by dates, which concern safety. | If I am buying ahead of the tea, I want to check the date and how to keep an opened pack. |
What is easy to overlook?
-
Assuming dark chocolate means the same allergen profile
The listed McVitie's, Asda and Marks & Spencer cakes have different ingredient or precautionary allergy statements.
Check the physical pack against each guest’s relevant allergens rather than relying on another brand’s label.
-
Counting servings as individual cakes
A 25g nutrition serving of Waitrose Mini Jaffa Cakes is not a count of mini cakes, and a coated bar is not the same piece format as a round cake.
Plan portions using the pack’s actual count or serving information and the number of guests.
-
Planning around a pack without checking availability
A listed format may not be available for the store or delivery slot you need.
Confirm availability before relying on a particular pack for afternoon tea.

Frequently asked questions
Does a dark-chocolate Jaffa cake have to be milk-free?
No. Asda lists milk in the ingredients of the McVitie's Original 110g pack and a may-contain-milk warning on its own-label 150g pack. Check the label of the cake you intend to serve.
How should I store Jaffa cakes after opening them?
The listed Asda own-label and Marks & Spencer dark-chocolate cakes say to keep them in a cool, dry place and use an airtight container once opened. Follow the directions on your particular pack if they differ.
Is a best-before date the same as a use-by date?
No. GOV.UK explains that best-before dates concern quality, whereas use-by dates concern safety. Check the date and storage directions on the pack you buy.
Do packaged Jaffa cakes need preparing for afternoon tea?
The listed packaged cakes are presented as ready to eat. Check the pack’s storage directions, and plan how many pieces to put out for your guests.
