Who is each format for?

The useful distinction is whether you need one item, one sealed serving or biscuits to portion from a packet.

One-person tea-break shoppers

A single large biscuit is not necessarily a single serving: Marks & Spencer describes its 270 g giant custard cream as made for sharing. A packet lets you put a few biscuits on a plate, but it is not individually portioned.

Afternoon-tea hosts

Packets work when you can plate biscuits for guests. If sealed portions matter, Business Beverages lists Crawford's three-biscuit packs, but the box contains several biscuit varieties rather than custard creams alone.

Hosts checking allergens

Read the label on the exact product you serve. Asda's plain custard creams list wheat and milk, alongside separate possible cross-contact warnings; a different recipe or coated variant needs its own check.

What should you check before buying?

Start with the serving format, then compare the recipe and what you will do with any biscuits left after tea.

PriorityWhat to checkYour needs
Serving format Check whether you are buying one large item, sealed portions or a packet. Marks & Spencer describes its 270 g giant biscuit as shareable; Business Beverages lists Crawford's three-biscuit portions in an assorted box of 100. For tea on my own, I want to know whether “one” means one item or one serving. For guests, separate sealed packs may matter more.
Filling and coating Compare the exact varieties: Tesco lists a vanilla-flavour filling, Marks & Spencer describes extra vanilla filling in its 165 g packet, and its giant biscuit has a milk-chocolate coating. I might want a plain sandwich biscuit with tea, or choose a coated treat to present and divide.
Ingredients and allergens Read the current pack's ingredients and allergen statements, including any cross-contact warnings. GOV.UK says regulated allergens used as ingredients in prepacked food must be clearly identified in the ingredients list. When serving someone with an allergy, I need to check the particular recipe rather than rely on the name “custard creams”.
Packet size and storage Compare the stated net weights, not just the number of packets. Check the physical pack's date and storage instructions; Asda tells buyers to keep its opened plain custard creams in an airtight container. If I am plating only a few biscuits, I want a packet size and storage arrangement that suit the next serving too.

Common buying mistakes

  • Assuming one bar means one serving

    Marks & Spencer sells one 270 g giant custard cream but describes it as made for sharing. Its format does not establish a one-person portion.

    Decide whether you want one item to present or a separate serving for each person.

  • Assuming wrapped portions are sold singly

    Business Beverages lists Crawford's sealed three-biscuit portions in a box of 100 across six varieties. Not every pack in the box is custard creams.

    Check the quantity you must buy and the assortment before choosing it for guests.

  • Treating plain and coated biscuits as the same recipe

    Asda's plain custard creams list wheat and milk, while its separately listed chocolate-coated variation lists soya, milk and wheat. The name alone does not establish identical ingredients.

    Check the label of the exact variant you intend to serve, particularly when a guest has an allergy.

Brand and retailer references

These examples show how formats differ; a brand's inclusion here does not mean every variety is sold as a single portion.

M&S

Marks & Spencer lists a 270 g chocolate-coated giant custard cream and a separate 165 g Extra Cream packet.

  • The giant is one physical item that Marks & Spencer describes as made for sharing.
  • The 165 g Extra Cream product is a packet, not a single bar.

Crawford's

Crawford's custard creams are listed in a 300 g packet; Business Beverages also lists assorted, individually wrapped biscuit portions.

  • Each sealed portion in the assorted offer contains three biscuits.
  • The offer is a box of 100 portions across several varieties, not a box of custard creams alone.

McVitie's

McVitie's Tasties Custard Creams are listed as a 300 g packet.

  • The packet provides biscuits that can be plated for tea.
  • A 300 g packet is not an individually wrapped bar.

Tesco

Tesco lists a 400 g packet of custard-cream sandwich biscuits with a vanilla-flavour filling.

  • The packet can be used when you plan to plate biscuits for several people.
  • The listing does not establish separate wrapped portions.

Sainsbury's

Sainsbury's lists its own-label custard creams in a 200 g packet.

  • The stated pack weight helps distinguish it from the larger packets discussed here.
  • A packet does not meet a requirement for one physical bar or a sealed individual portion.

Asda

Asda lists a 400 g plain custard-cream packet and a separate 162 g chocolate-coated variation.

  • The two listings distinguish a plain biscuit from a coated variation.
  • Their stated allergens differ, so check the label of the variant being served.

Questions about serving custard creams

Is M&S's giant custard cream a one-person bar?

It is one 270 g item, but Marks & Spencer describes it as made for sharing. If you need one serving for one person, do not treat “one bar” as a portion size.

Do Crawford's wrapped portions contain only custard creams?

No. Business Beverages describes a box of 100 sealed three-biscuit portions across six varieties, including custard creams. Check the assortment as well as the number of packs.

How should I keep an opened packet?

Follow the instructions on the packet you buy. Asda says its opened plain custard creams should be kept in an airtight container; check the physical pack for its storage directions and date.

What should I check before serving someone with a food allergy?

Read the current label of the exact product, including its ingredients and cross-contact warnings. GOV.UK says regulated allergens used as ingredients in prepacked food must be clearly identified in the ingredients list; Asda's plain and chocolate-coated custard creams list different allergens.
