Hikers wanting a small sweet snack
A dark-chocolate-coated marshmallow bar gives you a ready-to-eat portion without cutting up a larger bar. Check how you will carry it in warm weather, as well as its ingredients and allergen statement.
Who is each option for?
High-cocoa dark chocolate buyers
If cocoa content matters more to you than marshmallow texture, compare labelled dark chocolate bars instead. M&S lists 75% and 85% cocoa bars, but neither is a marshmallow product.
School-food purchasers in England
Food supplied in an English state-funded school is a different decision from packing a personal hiking snack. The Department for Education’s school-food guidance and England’s retail HFSS promotion rules address separate settings; check the applicable school-food requirements before purchasing for a school.
What should you check before packing one?
Decide whether you want a marshmallow snack or a chocolate bar, then check the portion, label and storage instructions against the conditions of your walk.
| Priority | What to check | Your needs |
|---|---|---|
| Snack format | Check the pack size and whether you can carry the portion you intend to eat. Waitrose & Partners lists the Mallow & Marsh Raspberry Bar as 35 g; check the wrapping or portioning of a larger chocolate bar separately. | I want a sweet snack that is straightforward to carry and eat on a walk. For a longer outing, I’ll plan food and water beyond a single bar. |
| Cocoa percentage | Read the percentage of chocolate in a coated product separately from the cocoa solids in that chocolate. Waitrose & Partners lists dark chocolate as 33% of the Mallow & Marsh bar, with at least 71% cocoa solids in that ingredient. M&S labels its alternative chocolate bars 75% and 85% cocoa. | If high cocoa is my main reason for choosing a snack, I need to know whether the figure describes a coating or a chocolate bar. |
| Nutrition label | Compare figures on the same basis, such as per 100 g or per serving. M&S lists 25.5 g sugars per 100 g for its 75% bar and 15.9 g per 100 g for its 85% bar; those figures alone do not describe a hiking portion. | I want to compare the amount I might actually pack, rather than treating different pack sizes or label units as equivalent. |
| Ingredients and allergens | Check the current pack for ingredients, declared allergens and possible traces. Waitrose & Partners lists beef gelatine and soya lecithin in the Mallow & Marsh bar; M&S labels its 75% and 85% bars vegan but says they are unsuitable for people with milk, nut or peanut allergy. | If I’m buying for someone avoiding animal ingredients or managing an allergy, the exact product label matters more than the word “dark”. |
| Storage | Read the storage instructions and consider where the snack will sit in your rucksack. The listed marshmallow and M&S chocolate bars specify cool, dry storage away from direct sunlight. | On a warm or exposed walk, I need to decide whether a chocolate-coated snack will be practical to carry. |
What is easy to overlook?

Reading the coating’s cocoa figure as the whole bar’s
Waitrose & Partners lists dark chocolate as 33% of the Mallow & Marsh Raspberry Bar, while the chocolate ingredient contains at least 71% cocoa solids. Those percentages describe different things.
If cocoa content is your deciding factor, check both figures on a coated snack and compare them with the label on a chocolate bar.
-
Leaving a chocolate snack in direct sun
The listed marshmallow and dark chocolate bars specify cool, dry storage away from direct sunlight. An exposed pocket may not suit those instructions on a warm walk.
Carry the snack inside your rucksack, away from direct sun, or consider another snack format if keeping it cool is impractical.
-
Assuming “dark” means vegan or suitable for allergies
The listed Mallow & Marsh bar contains beef gelatine. Although M&S labels its 75% and 85% chocolate bars vegan, it also states that they are unsuitable for people with milk, nut or peanut allergy.
Check the current pack’s ingredient and allergen statements for the exact product, particularly when buying snacks for a group.
-
Confusing school-food rules with retail HFSS rules
England’s school-food requirements concern food provided in state-funded schools. England’s HFSS promotion rules address retail promotions; they do not, by themselves, classify a particular marshmallow bar or decide what someone may pack for a personal hike.
For school catering, check the current school-food rules for the relevant UK nation. Do not apply an England-specific rule to every setting across the UK.
Which brand and retailer listings are relevant?
These listings help distinguish a coated marshmallow from a high-cocoa chocolate bar; a retailer listing is not a substitute for checking the current pack.
Mallow & Marsh
Its Raspberry Bar, as listed by Waitrose & Partners, is a 35 g raspberry marshmallow snack coated in dark chocolate.
- Waitrose & Partners lists dark chocolate as 33% of the bar and at least 71% cocoa solids in that chocolate ingredient.
- The listed bar contains beef gelatine and soya lecithin, with possible traces of egg, milk, peanuts and tree nuts.
M&S
M&S lists 75% and 85% cocoa dark chocolate bars for shoppers who do not need a marshmallow snack.

- Neither is a marshmallow product. M&S says both are unsuitable for people with milk, nut or peanut allergy.
Waitrose
Waitrose & Partners provides a listing for the dark-chocolate-coated Mallow & Marsh Raspberry Bar and a separate milk-chocolate-covered Double Chocolate Bar.
- The Raspberry Bar listing identifies a 35 g portion and supplies ingredient, nutrition and storage information.

Tesco
Tesco Groceries lists a Mallow & Marsh Dark Chocolate Over Raspberry Mallow 35 g product in its dark-chocolate category.
- The listing identifies a dark-chocolate marshmallow product by name and size.
- For ingredient or allergy decisions, consult the product’s current detail page and pack label rather than relying on the category listing.

Questions about hiking snacks
Does “70% dark chocolate” mean the whole marshmallow bar is 70% cocoa?
No. Waitrose & Partners lists dark chocolate as 33% of the Mallow & Marsh Raspberry Bar, and that chocolate ingredient has at least 71% cocoa solids. The cocoa figure describes the chocolate, not the complete marshmallow bar.
Is one dark-chocolate marshmallow bar enough for a long hike?
Do not plan a longer hike around one sweet bar alone. Brooks Running’s general guidance for longer activity discusses carrying carbohydrates and staying hydrated; consider the length and conditions of your walk when deciding what else to pack.
Is the listed dark-chocolate marshmallow bar vegan?
No. Waitrose & Partners lists beef gelatine in the Mallow & Marsh Raspberry Bar. M&S labels its separate 75% and 85% dark chocolate bars vegan and vegetarian, but says they are unsuitable for people with milk, nut or peanut allergy; check the current pack for the product you choose.
Do HFSS rules decide whether a dark-chocolate marshmallow bar can be served in a school?
Not as a single UK-wide “HFSS school-meal” rule. England’s Requirements for School Food Regulations 2014 define confectionery to include products wholly or partly coated with chocolate, while Department for Education guidance addresses food provided in state-funded schools in England. England’s HFSS retail-promotion rules are separate. For school catering, check the current school-food requirements for the relevant UK nation and setting rather than assuming a retail rule classifies this particular bar.
