For a routine after-school snack, choose fruit or vegetables rather than making a dark-chocolate bar the default; NHS guidance favours fruit and vegetables for children’s snacks. If chocolate is an occasional treat, compare the exact bar’s cocoa percentage, sugars per 100g, size and allergen label, and consider whether the child likes a more intense cocoa flavour. Food provided by a school calls for a separate check of the applicable rules and school policy.
Who is this for?
Parents choosing an occasional treat
A single bar may be what you have in mind for after school, but it need not become the routine snack. NHS guidance favours fruit and vegetables for children’s snacks; keep the chocolate decision separate from what to offer when a child is hungry after school.
Households comparing plain dark bars
If you are choosing between 70%–75% and 85%–100% cocoa bars, compare their current nutrition and allergen labels as well as the expected flavour. Cocoa percentage alone does not describe every difference that matters to the choice.
School and club food buyers
Food provided through a school or club raises questions beyond a parent-bought treat at home. Check which nation’s requirements apply, whether they cover the particular setting, and the school’s own food policy before ordering chocolate.
What should you check?
Decide whether you are choosing a routine snack or an occasional chocolate treat first. If it is a treat, compare like-for-like label values before considering which cocoa intensity is suitable.

What to check |
Your needs |
| Snack or treat |
Decide whether the food is for the usual after-school snack or an occasional treat. NHS guidance favours fruit and vegetables for children’s snacks; a dark-chocolate bar remains confectionery. |
My child is hungry after school, so I want to choose the snack before deciding whether to offer chocolate as a treat. |
| Nutrition label |
Compare sugars and saturated fat per 100g on the exact bars. Then check the bar weight and the amount you intend to offer; a per-100g figure is not a figure for the whole of a 90g bar. |
I want to compare the labels on the same basis rather than assume that a higher cocoa percentage settles the choice. |
| Cocoa flavour |
Check the stated cocoa percentage and the product’s flavour description. A 70%–75% bar and an 85%–100% bar may present different levels of cocoa intensity; the percentage does not establish whether a child will enjoy either one. |
If the chocolate is an occasional treat, I want a cocoa intensity the child is willing to eat, not simply the highest percentage on the shelf. |
| Allergens |
Read the current ingredients and allergen statement for the exact variant, including any may-contain wording. A vegan recipe does not establish suitability for a milk allergy: Lindt says its EXCELLENCE 70% bar is not suitable for people with milk allergy. |
Where an allergy is relevant, I need to assess this particular pack rather than rely on a general brand or vegan description. |
| School provision |
Confirm the nation, the type of school or club provision and the applicable food policy. The Department for Education’s school-food guidance addresses state-funded schools in England; South Lanarkshire Council publishes separate standards for its school food. |
I am buying food to be provided through a school or club, rather than choosing a treat to offer at home. |
Common buying mistakes
-
Making chocolate the routine after-school snack
A high cocoa percentage does not change the fact that a dark-chocolate bar is confectionery. NHS guidance favours fruit and vegetables for children’s snacks.
Choose the usual after-school snack on its own merits, and consider a bar separately as an occasional treat.
-
Judging the bar by cocoa percentage alone
The researched plain bars have different declared sugars per 100g, while cocoa percentage by itself says nothing conclusive about the amount of saturated fat in the portion offered.
Read the exact pack’s nutrition table on a per-100g basis, then check its weight and the portion you intend to serve.
-
Assuming a vegan bar is suitable for a milk allergy
Lindt describes its EXCELLENCE 70% bar as made to a vegan recipe but says it is not suitable for people with milk allergy. Other bars also carry product-specific may-contain statements.
Check the current allergen panel for the precise bar and variant when buying for someone with a diagnosed allergy.
-
Applying home-treat choices to school food
A parent buying chocolate to offer at home is making a different decision from someone procuring food for a school. Requirements depend on the nation and on the provision involved.
Before ordering for a school, tuck shop or club, confirm the applicable requirements with the setting and check its food policy.
Brand references for plain dark bars
These examples help distinguish specific cocoa percentages and label details; a brand name alone cannot establish the nutrition or allergy information for a different bar.
Divine
Divine’s 70% dark-chocolate bar is a 90g option.
- Divine lists 28.9g sugars per 100g for this bar.
- Its product information says it may contain gluten, milk and nuts; check the current pack when allergies matter.
Lindt
Lindt EXCELLENCE includes a 100g bar with 70% minimum cocoa solids.
- Lindt lists 29g sugars per 100g for the EXCELLENCE 70% bar.

Montezuma’s FitzRoy is a 74% cocoa bar, while Absolute Black is a distinct 100% cocoa bar.
- Montezuma’s lists 25g sugars per 100g for FitzRoy and 0.6g per 100g for Absolute Black.
- The 100% bar has a much more intense cocoa profile. Both product descriptions carry may-contain wording for milk, nuts and peanuts.

Questions about after-school treats
Should a dark-chocolate bar be the everyday after-school snack?
No: keep a bar as an occasional treat rather than the default snack. NHS guidance favours fruit and vegetables for children’s snacks, and a higher cocoa percentage does not turn confectionery into a routine snack choice.
Does a higher cocoa percentage settle which bar to buy?
No. The researched bars have different labelled sugars per 100g, but cocoa percentage alone does not settle flavour preference, portion size, saturated fat or allergy suitability. Compare the exact current labels and choose a cocoa intensity the child accepts.
Can an after-school club provide dark-chocolate bars?
Check the nation, the club’s setting and its food policy before ordering. The Department for Education’s school-food guidance concerns state-funded schools in England, where school-food standards restrict snacks across the school day; South Lanarkshire Council’s school-food information separately says confectionery cannot be offered across the school day in its schools. These sources do not establish one rule for every club or every UK nation.
Is a vegan dark-chocolate bar suitable for someone with a milk allergy?
Not necessarily. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with milk allergy. Check the exact current bar’s allergen statement rather than relying on the word “vegan”.
