For a back-to-school treat, start by choosing a cocoa level the recipient already enjoys: a plain 70% bar is a starting point if they are new to stronger dark chocolate, while higher-cocoa bars suit an established preference. Before putting any bar in a school bag, decide how much to pack, read its current allergen label and check the individual school’s policy.
A bar packed from home raises a different question from food provided by a school. The Department for Education’s school-food guidance concerns food and drink provided in state-funded schools in England; check your school’s packed-lunch and allergy policies before packing chocolate.
If the recipient has not settled on a stronger cocoa flavour, compare plain 70% bars before choosing a 74% or 85% option. Cocoa percentage helps distinguish the bars, but their taste preference should decide the choice.
Do not use “dark” or “vegan” as a substitute for an allergen check. Read the current wrapper against the individual’s allergy plan, including any precautionary warning, and check the school’s requirements if the bar will be taken in.
Choose the format and cocoa level for the recipient first, then check the actual bar and the school setting before deciding what to pack.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa level | Compare the stated cocoa percentage and whether the bar is plain. Divine, Lindt and Green & Black's have documented 70% options; Montezuma's FitzRoy is 74%, and the M&S Collection bar is 85%. | I’m choosing for someone whose taste I know, rather than assuming the highest cocoa percentage will suit them. |
| Allergens | Read the current ingredients, highlighted allergens and any “may contain” statement. Compare them with the individual’s allergy plan; a vegan recipe does not settle milk-allergy suitability. | If an allergy matters, I need to check this particular wrapper before the bar is bought or packed. |
| School use | Check the individual school’s packed-lunch and allergy policies. England’s Department for Education school-food guidance addresses food provided in state-funded schools, not permission for a particular home-packed bar. | I want to know whether this bar can go into this school, rather than assuming the same rule applies everywhere. |
| Bar and portion | Check the bar weight and decide how much to pack. A single 90g or 100g wrapper does not establish that its contents are one school-day serving. | For a school-bag treat, I may want to divide a larger bar at home instead of packing it whole. |
| Recipe preferences | Check whether the bar is plain or contains fruit or other additions. Confirm organic, Fairtrade or other stated attributes on the exact product rather than applying them to every bar from a brand. | I’d choose a plain recipe for a straightforward comparison, or a fruit-containing bar if that is what the recipient prefers. |
Dark bars can carry milk, nut and other allergen warnings. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy.
Follow the individual allergy plan and read the current wrapper’s ingredients and precautionary statements before choosing a bar.
The reviewed 90g and 100g bars are not pre-portioned school snacks. Packing a whole bar may differ from the amount a household intended to send.
Decide the portion at home and check the school’s packed-lunch policy.
A 70%, 74% or 85% label identifies a difference between these bars, not which flavour a particular recipient will enjoy.
Use the recipient’s existing preference to choose between a 70% starting point and a higher-cocoa option.
Ingredients and allergen information can change. M&S advises checking product information when choosing its dark chocolate.
Use listings to narrow the options, then make any allergy-sensitive decision from the current pack.
These references describe particular bars and ranges, not every product made by each brand or the selection available on Joybuy.

No image available

No image available

This 90g bar contains raspberry pieces, so choose it for someone who wants fruit in their dark chocolate rather than a plain bar. Check the current wrapper’s milk and other allergen information before buying, especially where allergies matter.
Check the individual school’s packed-lunch and allergy policies before packing it. The Department for Education’s school-food guidance for England addresses food and drink provided in state-funded schools; it does not establish whether a particular home-packed bar is permitted.
Not automatically. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Follow the person’s allergy advice and check the current label of the exact bar.
Read the ingredients, highlighted allergens and any “may contain” warning, then compare them with the individual’s allergy plan. The Food Standards Agency says allergens present in prepacked food must be emphasised in its ingredients list; precautionary warnings also differ between bars.
One wrapper does not establish a school-day portion. Decide how much to pack or share at home, and check any relevant school policy before sending it in.
Choose according to the recipient’s existing taste preference rather than treating a higher percentage as automatically preferable. Plain 70% bars provide a starting point for comparison; Montezuma's FitzRoy is a 74% option, while an 85% bar is worth considering for someone who already likes higher-cocoa chocolate.
