Choose individually wrapped three-cake packs if you want to put one portion in a gym bag; choose a larger pack if you can portion the cakes yourself and follow its storage instructions after opening. If you want a post-exercise snack containing both carbohydrate and protein, consider what else you plan to eat: Tesco Groceries lists 22.8 g carbohydrate and 1.6 g protein per three-cake serving of McVitie’s snack packs.
McVitie’s six-by-three format has six individually wrapped servings, so you can take one pack rather than an opened box. If you also want protein in a snack before your next meal, compare the serving’s nutrition with what else you plan to eat.
A twin or triple pack may suit you if you can portion cakes before leaving and use the rest. Check the particular pack’s directions for storing it after opening.
Look at the exact product label if allergens or nutrition affect your choice. Jaffa-style cakes are labelled on different serving bases, including per cake, per 25 g and per three-cake pack.
Start with the portion you can carry and store, then compare nutrition and ingredients using the serving size on each pack.
| Priority | What to check | Your needs |
|---|---|---|
| Portion to carry | Tesco Groceries lists six separate three-cake servings in the McVitie’s snack pack. Ocado lists five individually wrapped McVitie’s cake bars, which are a different product and serving. | I want to take one wrapped portion without carrying an opened pack. |
| Nutrition per serving | Tesco Groceries lists 22.8 g carbohydrate and 1.6 g protein per three-cake McVitie’s snack-pack serving. Compare other products on their own stated serving bases; a bar or mini cake is not an equivalent serving. | If there is a long gap before my next meal, I want to know what the cakes contribute and whether the rest of my food includes protein. |
| Ingredients and allergens | Read the supplied pack’s ingredients and allergen information. Tesco’s McVitie’s snack-pack listing declares milk, egg, soya and wheat ingredients; other Jaffa-style products have their own labels. | The precise product matters to me when checking an ingredient or comparing sugar per stated serving. |
| Quantity and storage | Check the pack count and whether portions are separately wrapped. Follow the opened-pack directions: Tesco’s own-label twin pack says to store it airtight and consume it within two days of opening. | I can portion cakes myself, but I want a pack size I expect to use while following its storage instructions. |
For McVitie’s three-cake snack packs, Tesco Groceries lists 22.8 g carbohydrate but 1.6 g protein per serving. University College London Hospitals NHS Foundation Trust describes post-activity snacks that contain both carbohydrate and protein.
If that combination is what you want before your next meal, consider the other food you plan to have rather than treating the cakes as the whole snack.
Nutrition may be shown per cake, per bar, per 25 g or per three-cake serving. Numbers on those different bases do not describe the same portion.

No such prohibition follows from those rules. The UK Department of Health and Social Care’s less-healthy-food guidance concerns advertising of products that meet its scope tests, not an adult’s snack purchase. Department for Education school-food guidance concerns food provided in state-funded schools in England; it does not classify every Jaffa Cakes product or govern this post-gym purchase. Proposed changes for September 2027 remain subject to Parliamentary approval.
