For a picnic snack where calories per cake are the main consideration, start by comparing plain or lightly salted cakes: Kallo UK and Asda Groceries list two Kallo variants at 27 kcal each, while Sainsbury's lists 29 kcal and Asda lists 30 kcal for its own-label cake. Flavoured cakes offer a different choice, but the figure depends on the exact variety and size: Snack A Jacks lists 38–62 kcal across the cited Jumbo flavours. Count any toppings as part of the snack, and check the current pack for ingredients and allergen advice.
If you plan to eat individual cakes, a per-cake figure makes the portion easier to work out than a general “light” description. The plain and lightly salted products listed by Kallo UK, Sainsbury's Groceries and Asda Groceries range from 27 to 30 kcal per cake.
A plain or lightly salted cake lets you choose the topping separately. Check both parts of the finished snack if calories, salt or allergens matter to your picnic plans.
Check claims and allergen advice for the exact variety. For example, Asda Groceries lists Kallo Organic Lightly Salted as gluten free but says it may contain milk, soya and sesame.
Decide how many cakes you will pack, then compare the nutrition figures for that portion and anything you intend to add.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per portion | Find kcal per cake or pack and count the amount you expect to eat. The NHS explains that labels give energy per 100g and sometimes per portion. | I want to know the calories in the number of cakes I will actually take, including any toppings. |
| Flavour and nutrition | Compare the exact variety's salt and sugars as well as kcal. Snack A Jacks lists 38 kcal for Sour Cream & Chive Jumbos, 51 kcal for Caramel and 62 kcal for Chocolate Chip. | A ready-flavoured cake would be convenient, but I do not want to assume it has the same figures as a plain cake. |
| Ingredients and allergens | Read the current pack's ingredient list, dietary claims and allergen statement. Check each variant separately, particularly when food will be shared. | If someone at the picnic has a dietary or allergen requirement, I need to confirm that the particular pack is suitable before serving it. |
Kallo UK lists 27 kcal for its Lightly Salted cake, whereas Snack A Jacks lists 38–62 kcal across the cited Jumbo flavours. Cake size and flavour affect which figures are useful to compare.
Check kcal for the exact cake or individual pack you intend to eat, rather than relying on the category name.

Work out the planned portion using the cake's label and the amount of topping you add.
