Shoppers comparing sugar labels
You want to keep Jaffa cakes in the mix without mistaking a slightly lower sugar figure for a substantiated ‘reduced sugars’ claim.
Who is this for?
People taking breakfast on the move
You need something easy to carry and want to decide whether a Jaffa cake is an addition to breakfast or whether another quick food combination better meets your needs.
What should you check?
Compare sugar per 100g before considering the portion you will eat, then decide what else you need from breakfast.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Compare total sugars per 100g on the exact packs. For a UK ‘reduced sugars’ claim, legislation.gov.uk sets a reduction of at least 30% against a similar product and requires that energy is no higher. | I want to know whether a cake qualifies for that claim, not just whether its label shows less sugar than another pack. |
| Planned portion | Check the pack’s serving size and sugar figure for the number of cakes you intend to eat. Waitrose lists McVitie’s Original 10-pack at 5.4g sugars per cake; that figure belongs to that pack. | On a rushed morning, I want to know the sugar in the portion I will actually take with me. |
| Breakfast choice | If breakfast needs to be more than a sweet snack, consider a fibre-rich carbohydrate, a protein source and fruit or vegetables, as suggested by NHS breakfast guidance. Check the labels and portions of the foods you choose. | I need a quick breakfast, rather than assuming a portable cake covers everything I want from the meal. |
Common comparison mistakes
-
Calling a small difference ‘reduced sugars’
Sainsbury’s, M&S and Waitrose listings give different sugar figures per 100g, but those differences alone do not establish a UK ‘reduced sugars’ claim.
Use the exact labels to describe a difference between named packs. Reserve ‘reduced sugars’ for a product whose comparison meets the applicable claim conditions.
-
Comparing unlike portions
Waitrose lists 5.4g sugars per cake for McVitie’s Original 10-pack, but 12.8g per 25g serving for Waitrose Mini Jaffa Cakes. A cake and a 25g serving are not the same unit.
Use per-100g figures to compare the products, then check the serving information on the pack you will eat.
-
Treating a portable snack as the whole breakfast
Being easy to carry does not address the other elements of breakfast described in NHS guidance, including a fibre-rich carbohydrate and a protein source.
If you choose Jaffa cakes, consider what else you want alongside them; if the meal matters more than the snack, plan a quick combination of breakfast foods instead.
Brand and own-label references
These labelled products offer points of comparison, not a ranking of brands or evidence that any one of them qualifies for a ‘reduced sugars’ claim.
McVitie’s
Waitrose’s listing for McVitie’s Original 10-pack gives both a per-cake and a per-100g sugar figure.
- The listing states 5.4g sugars per cake, which can help with planning a portion of that product.
- It also states 50.0g per 100g; the NHS classifies more than 22.5g sugars per 100g as high.
Sainsbury’s
The Sainsbury’s Jaffa Cakes x24 282g listing provides another own-label figure to compare on a per-100g basis.
- Its listed sugar content is 46.8g per 100g.
- That figure remains above the NHS high-sugar threshold and does not, by itself, establish a ‘reduced sugars’ claim.
M&S
The M&S Dark Chocolate Jaffa Cakes 250g listing identifies a dark-chocolate product with labelled sugar information.
- The listing states 47.2g sugars per 100g for this product.
- It carries a nut-allergy suitability warning. Check the pack if this affects you; dark chocolate does not establish a sugar-reduction claim.
Waitrose
Waitrose Mini Jaffa Cakes provide a smaller-format product with a labelled 25g serving.
- The listing states 12.8g sugars per 25g serving.
- It states 51.1g sugars per 100g. ‘Mini’ describes the format, not a reduced-sugar formulation.
Tesco
Tesco’s Jaffa Cakes 141g provide another own-label product to consider when checking packs in person.
- Check the current pack’s nutrition label before comparing its sugar content with another product.

McVitie’s The Original Jaffa Cakes Snack Pack 6 x 3pk 198g
The 6 x 3pk format offers smaller packs to take on the move. Check this pack’s nutrition label for the sugar in the number of cakes you plan to eat; do not use the per-cake figure from a different McVitie’s pack.

McVitie’s Jaffa Cakes Original Triple Pack 330g
The 330g triple pack is a different format from the smaller snack packs. If you are taking cakes out for breakfast, check the pack’s serving information and portion them accordingly; the triple-pack name is not a sugar claim.
Questions about Jaffa cakes
Does a lower sugar figure per cake mean it is low sugar?
No. The NHS uses sugar per 100g for its food-label guidance: more than 22.5g is high, while 5g or less is low. Use the per-cake figure separately to work out the sugar in your planned portion.
Can I call a Jaffa cake ‘reduced sugars’ if it has less than another brand?
Not on that comparison alone. The UK nutrition-claim provision published on legislation.gov.uk requires at least 30% less sugar than a similar product and no higher energy for a ‘reduced sugars’ claim. The products discussed here are not established as meeting those conditions.
How should I store an opened pack?
Follow the instructions on the pack you buy. For example, Waitrose’s McVitie’s Original listing says to store it in a cool, dry place and use an airtight container once opened.
What if I need to check allergens?
Read the ingredients and precautionary statements on the exact pack before eating it. The checked M&S Dark Chocolate Jaffa Cakes listing carries a nut-allergy suitability warning; do not apply one product’s information to another pack.
