Sugar-conscious cream-tea hosts
Compare total sugars on the same per-100g basis, then use the labelled serving figures to plan how many cakes to put out.
Who is this for?
Shoppers choosing a serving format
Check whether standard cakes, minis or a multipack fit your group. A suggested serving and an individual cake are not necessarily the same quantity.
Hosts accommodating food allergies
Read the ingredients and precautionary warnings on each exact pack before serving guests with allergies; the checked products differ.
What should you compare?
Start with the per-100g figure for a like-for-like comparison, then consider the quantity you will serve and any requirements of your guests.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Compare total sugars in g per 100g on the exact packs. Sainsbury’s x24 lists 46.8g, M&S Dark Chocolate 47.2g and McVitie’s Original 50.0g per 100g. | I want to compare sugar on an equivalent-weight basis, rather than assume a smaller cake contains less sugar overall. |
| Amount served | Check whether the other figure is per cake or per suggested serving. McVitie’s lists 5.4g sugars per Original cake; Waitrose lists 12.8g per 25g serving of its minis. | If I put out several cakes per guest, the sugar figure for one cake or one suggested serving may not describe what each person takes. |
| Pack format | Check cake count or pack weight against your group size. Sainsbury’s x24 contains 24 cakes; Tesco’s Orange Jaffa Cake twin pack is 2 × 150g. Tesco says to consume its pack within two days of opening. | For a larger cream tea, I need enough cakes without overlooking what to do with an opened pack afterwards. |
| Allergens | Read the current pack’s ingredients and precautionary warnings. Sainsbury’s x24 carries a milk-allergy manufacturing warning; M&S Dark Chocolate warns about nut allergies. | Before serving a guest with an allergy, I need to check the particular product they will be offered. |
Comparisons to watch out for
-
Calling a lower figure ‘low sugar’
The NHS describes food with more than 22.5g total sugars per 100g as high in sugar. Sainsbury’s x24, at 46.8g per 100g, is lower than some of the packs compared here but remains above that threshold.
Describe the specific per-100g difference instead. Do not treat a relative comparison as proof of a ‘low sugar’ or ‘reduced sugars’ claim.
-
Comparing a mini-pack serving with one standard cake
ASDA states sugar per cake for its standard Jaffa Cakes but per suggested one-fifth-pack serving for its minis. Those figures describe different amounts of food.
Compare the packs per 100g first, then check the labelled figure for the quantity you intend to put out.
-
Relying on a marketplace title to identify the pack
An accessed Joybuy listing titled McVitie’s Original also referred to a Milka sandwich in its description and listed 52.6g sugars per 100g, rather than the 50.0g on McVitie’s UK Original listing.
Confirm the product identity and nutrition on the current physical pack before using a marketplace listing for this comparison.
Brand and product-line references
These figures describe the named UK product listings, not every Jaffa Cake made by each brand.
McVitie’s
McVitie’s publishes nutrition for its Original Jaffa Cakes per 100g and per cake.
- Original lists 50.0g total sugars per 100g and 5.4g per cake.
- A per-cake figure does not make it lower in sugar per 100g than the Sainsbury’s x24 or M&S Dark Chocolate listings.
Sainsbury’s
The checked own-label x24 pack provides both per-100g and per-cake sugar figures.
- Jaffa Cakes x24 lists 46.8g total sugars per 100g and 5.5g per cake.
- The accessed listing displayed the pack as out of stock; check availability before planning around it.
M&S
The checked Dark Chocolate and Mini Jaffa Cakes have separate nutrition listings.
- Dark Chocolate lists 47.2g total sugars per 100g; Mini lists 47.9g per 100g.
- Check the intended serving rather than assuming either per-100g figure describes one cake. Read the packs’ nut-allergy warnings before serving.
ASDA
The checked standard and mini packs state sugar for different serving quantities.
- Standard Jaffa Cakes list 50g total sugars per 100g and 6.3g per cake.
- Mini Jaffa Cakes list 51g per 100g and 15g per suggested one-fifth-pack serving, not per individual mini cake.
Waitrose
The checked own-label Mini Jaffa Cakes list nutrition per 100g and per 25g serving.
- The mini pack lists 51.1g total sugars per 100g and 12.8g per 25g serving.
- Its 25g serving is not directly comparable with another pack’s per-cake figure.
Tesco
The checked Orange Jaffa Cake Spongy & Fruity twin pack contains 2 × 150g.
- It lists 51.2g total sugars per 100g and 6.7g per cake.
- Tesco instructs shoppers to consume the pack within two days of opening.

McVitie’s The Original Jaffa Cakes Snack Pack 6 x 3pk 198g
The 6 x 3pk format lets you put out smaller packs for a cream tea. Check this pack’s total sugars and allergen information before serving; the format alone does not establish a lower-sugar choice.
No image available
McVitie’s 80 Jaffa Cakes 1.07kg
The 80-cake, 1.07kg pack offers a larger quantity for a group. Plan how many cakes to serve and check the exact pack’s nutrition and allergen information; pack size does not change the basis for comparing sugar per 100g.
Questions about serving Jaffa Cakes
Does ‘mini’ mean less sugar?
No conclusion follows from the size alone. ASDA’s checked Mini Jaffa Cakes list 51g total sugars per 100g, compared with 50g for its standard Jaffa Cakes. Compare the same weight, then check how much you intend to serve.
What should I check before serving guests with allergies?
Read the current physical pack’s ingredients and precautionary warnings for every product served. Sainsbury’s x24 carries a milk-allergy manufacturing warning, while M&S Dark Chocolate carries nut and peanut warnings.
Is labelled total sugar the same measure as free sugars?
No. A nutrition label reports total sugars, while the NHS defines free sugars separately. Do not treat a Jaffa Cake’s total-sugars figure as an identical measure when reading the NHS guidance on free sugars.
Can I call the lowest figure in this comparison ‘reduced sugars’?
Not on the per-100g figures alone. They show differences between the named packs; they do not establish whether a product meets the conditions for a regulated ‘reduced sugars’ claim. UK government guidance says nutrition claims are subject to rules.
How should I handle an opened pack after the cream tea?
Follow the storage instructions on the exact pack. For example, Tesco says to store its opened Orange Jaffa Cake twin pack airtight and consume it within two days.
