For a midnight snack, choose by the amount you plan to eat: McVitie’s Original lists 41 kcal per cake, while Waitrose Mini Jaffa Cakes list 12.8g sugars per 25g serving and 24% dark chocolate in the recipe, according to Waitrose & Partners. A recipe’s dark-chocolate percentage is not its cocoa-solids percentage, so check the pack if cocoa content is your deciding factor.
If you plan to have one or two cakes, per-cake figures are more useful than pack size alone. Waitrose & Partners lists 41 kcal and 5.4g sugars per McVitie’s Original cake; its Mini Jaffa Cakes listing instead gives figures for a 25g serving.
The compared product listings describe dark chocolate, but a percentage of dark chocolate in the recipe does not tell you the cocoa-solids percentage. Check for a separate cocoa-solids figure if that distinction matters to you.
Read the exact pack before buying or sharing. Marks & Spencer says its Dark Chocolate Jaffa Cakes are not suitable for people with a nut or peanut allergy, while the Ocado listing for Bahlsen Messino warns that it may contain hazelnuts.
Start with the chocolate ingredients, then compare nutrition for the amount you would actually eat and check the pack’s allergen information.
| Priority | What to check | Your needs |
|---|---|---|
| Dark chocolate | Check that the ingredients say dark chocolate. Waitrose & Partners lists 24% for its Mini Jaffa Cakes and 19% for the McVitie’s Original twin pack; Marks & Spencer lists 19% for its Dark Chocolate Jaffa Cakes, as does Ocado for Bahlsen Messino. These are recipe proportions, not cocoa-solids figures. | I want a dark-chocolate coating. If I am choosing by cocoa content, I need a separately stated cocoa-solids percentage rather than the coating’s share of the recipe. |
| Portion basis | Compare figures on the same basis before deciding how many cakes to eat. Waitrose & Partners lists 41 kcal and 5.4g sugars per McVitie’s Original cake, but 104 kcal and 12.8g sugars per 25g serving of its Mini Jaffa Cakes. | For a late-night snack, I would rather decide on a number of cakes or a serving size first than compare the two listed figures as though they described equal portions. |
| Allergens | Read the current ingredients and precautionary statements on the exact pack. Marks & Spencer says its product is not suitable for people with a nut or peanut allergy; Ocado says Bahlsen Messino may contain hazelnuts. | If I am buying for someone with an allergy, the warning on the particular pack matters more than whether another Jaffa Cake has a similar name or coating. |
A listing may give the percentage of dark chocolate used in the whole recipe without giving the cocoa-solids percentage of that chocolate. The two figures answer different questions.
If cocoa content determines your choice, look for an explicit cocoa-solids figure on the pack or manufacturer’s product information.
Per-cake figures and a 25g serving figure cannot be compared as if they represent the same amount of food.
Choose the amount you intend to eat, then use each pack’s nutrition information to compare that amount.
Warnings differ between listings. Marks & Spencer identifies nut and peanut allergy concerns for its Dark Chocolate Jaffa Cakes, while Ocado lists possible hazelnut presence for Bahlsen Messino.
Check the physical pack each time, particularly when sharing the snack or buying a different variant.

No: the dark-chocolate percentages stated in the compared product listings describe how much of the recipe is dark chocolate, not the cocoa-solids content of that chocolate. Look for an explicit cocoa-solids percentage if you want to choose on that basis.
Waitrose & Partners lists 24% dark chocolate for its Mini Jaffa Cakes, compared with 19% in the listings for the McVitie’s Original twin pack, M&S Dark Chocolate Jaffa Cakes and Bahlsen Messino. That comparison concerns the stated share of each recipe, not cocoa intensity.
