Hosts looking for a reduced-sugar product
If the claim matters, look for it on the product packaging and check what comparable product it refers to. A small cake or a lower per-piece figure does not establish that claim.
Who are you serving?
Hosts planning portions of standard Jaffa Cakes
Use the stated serving as well as the per-100g figure. Sainsbury’s lists 5.4g sugars per cake for McVitie’s Original x10 and 6.2g per cake for its own Orange Jaffa Cakes 150g; those figures describe different products and servings.
Hosts serving guests who avoid gluten
Schär describes its Jaffa Cakes as gluten-free and wheat-free. Check the current pack against each guest’s requirements, including its trace-allergen statement.
What should you check before buying?
Start with the sugar information and any claim on the pack, then choose a serving format that works for your table and your guests.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar information | Read any reduced-sugar claim and its comparison basis. Compare sugars per 100g across products; use the stated serving figure to plan portions. A traffic-light label, where shown, is another way to read the pack’s nutrition information. | I want to assess the sugar information rather than judge by cake size. In a 2024 Food Standards Agency and Ipsos survey of 611 adults in Northern Ireland, 49% said they actively used traffic-light labelling when shopping for food; that figure is about food shopping, not Jaffa Cakes specifically. |
| Serving format | Check how many cakes or smaller packs are included and what the nutrition table defines as a serving. Do not compare per-cake figures without accounting for cake size. | For a shared table, I want to decide how many cakes to put out at once and keep the serving information clear. |
| Guest requirements | Read the full ingredient, allergen and trace statements on the current pack. Check a gluten-free description separately from other allergy requirements. | I need an option that matches the requirements of the guests attending, rather than assuming a gluten-free cake suits every allergy. |
| Outdoor serving | Follow the pack’s storage directions. Keep reserve packs in a cool, dry, shaded place and check the instructions for opened packs. | I would rather replenish the plate than leave all the chocolate-coated cakes in direct sunlight. |
What is easy to overlook?

Calling a smaller cake reduced sugar
A per-piece figure changes with serving size. Sainsbury’s lists 49.6g sugars per 100g for its Orange Jaffa Cakes 150g, while Waitrose lists 51.1g per 100g for its Mini Jaffa Cakes.
Compare per-100g figures for the products you are considering, and use per-piece or stated-serving figures to plan what goes on each plate. Check the pack for an actual reduced-sugar claim.

Assuming gluten-free covers every allergy
Schär describes its Jaffa Cakes as gluten-free and wheat-free, but its product information says they may contain traces of hazelnuts and milk.
Ask guests about their requirements, check the current packaging and keep it available when serving.
-
Putting every pack out in the sun
The product guidance for the cakes discussed here calls for cool, dry storage, with Sainsbury’s also specifying a place away from direct sunlight.
Keep reserve packs shaded and bring out smaller amounts as needed. Follow the pack’s directions for storing any opened cakes.
Which product lines are relevant?
These examples illustrate different pack and dietary formats; their nutrition figures apply to the named products, not every item from each brand.
McVitie’s
Original Jaffa Cakes offer a familiar orange-centre, sponge and chocolate format.
- Sainsbury’s lists 5.4g sugars per cake and 50g per 100g for McVitie’s Original x10.
- The x10 product contains wheat, egg, milk and soya. Its per-cake figure does not make it a reduced-sugar product.
Sainsbury’s
Orange Jaffa Cakes 150g are an own-label standard-cake option.
- Sainsbury’s lists approximately 12 servings, with 6.2g sugars per cake and 49.6g per 100g.
- The product’s allergen statement includes wheat, egg and soya. Do not treat its serving figure as a reduced-sugar claim.
Waitrose
Mini Jaffa Cakes provide a smaller-format option with a stated 25g serving.
- Waitrose & Partners lists 12.8g sugars per 25g serving.
- The same product lists 51.1g sugars per 100g, so its mini format should not be taken as a reduced-sugar claim.
Schär
Schär Jaffa Cakes are described by the brand as gluten-free and wheat-free.
- The brand lists 44g sugars per 100g for this product.
- That figure alone does not establish a reduced-sugar claim. The product may contain traces of hazelnuts and milk.

These McVitie’s packs offer three ways to buy standard Jaffa Cakes for a garden-party table: a bulk pack, smaller snack packs or a triple pack. Check the current packaging if a reduced-sugar claim or an allergen requirement is decisive.

McVitie’s 80 Jaffa Cakes 1.07kg
The 80-cake pack is a bulk format if you plan to replenish a shared plate. Check its current sugar and allergen information before serving; pack size does not establish a reduced-sugar claim.
No image available
McVitie’s The Original Jaffa Cakes Snack Pack 6 x 3pk 198g
The 6 x 3pk format lets you put out smaller packs rather than opening one larger pack at once. Compare the current label’s sugars per serving and per 100g before choosing it for a sugar-related requirement.
No image available
McVitie’s Jaffa Cakes Original Triple Pack 330g
The 330g triple-pack format gives you separate packs to set out as needed. Check its current serving and allergen information; a comparison with other biscuits is not, by itself, a reduced-sugar claim for these Jaffa Cakes.
Common questions
Does a smaller Jaffa Cake count as reduced sugar?
No: a smaller piece can have less sugar per piece without having less sugar per 100g. Compare the per-100g figures and check the pack for an explicit reduced-sugar claim and its comparison basis.
How do I compare portions for a party?
Use the nutrition table’s stated serving and the number of cakes you expect to put out. For example, Sainsbury’s lists 5.4g sugars per cake for McVitie’s Original x10 and 6.2g per cake for Sainsbury’s Orange Jaffa Cakes 150g; use their per-100g figures for a comparison that accounts for different cake sizes.
Will gluten-free Jaffa Cakes suit every guest with an allergy?
Not necessarily. Schär describes its Jaffa Cakes as gluten-free and wheat-free, but says they may contain traces of hazelnuts and milk. Check the current pack against each guest’s requirements.
How should I keep Jaffa Cakes during an outdoor party?
Follow the pack’s storage directions and keep reserve packs in a cool, dry, shaded place. Put out smaller amounts as needed rather than leaving all the cakes in direct sunlight.
