For an after-school snack, treat dark chocolate mints as an occasional, planned sweet rather than the main answer to hunger. If you choose them, decide the portion before serving, compare sugars on the current pack and check allergens; a higher cocoa percentage alone does not tell you how much sugar a mint contains.
Who is this for?
Parents planning an occasional sweet treat
If a child wants something sweet after school, a defined portion and the sugars shown on the pack matter more than the word “dark”. When the child is hungry, consider what will make up the rest of the snack too.
Households checking food allergens
Dark-mint products can have different ingredients and precautionary allergen statements. Check the current pack against the particular allergy or intolerance before choosing a product.
Shoppers comparing cocoa claims
A cocoa percentage describes a specified chocolate component; it does not replace the sugars figure or tell you what portion to serve. Fillings and formats also differ.
What matters when choosing?
Start with the role of the after-school snack, then check the portion, nutrition label and ingredients of the format you are considering.
| Priority | What to check | Your needs |
| Snack or treat |
Decide whether the mint is an occasional sweet or is meant to satisfy hunger. Consider the sugars in the planned portion alongside the rest of the day’s food and drinks. |
If I am buying for a hungry child, I want to plan the snack itself rather than rely on a few mints to serve that purpose. NHS guidance notes that snacks and sugary drinks account for a substantial part of children’s sugar intake. |
| Portion |
Look for sugars per piece or stated serving, and check how many pieces that serving contains. If only a per 100g figure is shown, establish the portion before comparing it with another product. |
A single piece is easier for me to set aside in advance than an open bar or sharing box. Sainsbury’s lists 17.2g sugars per three After Eight mints, so its stated serving is three pieces, not one. |
| Cocoa and sugars |
Read the cocoa declaration alongside sugars per 100g and per stated serving. Check whether a cocoa claim applies to the chocolate shell rather than the filled mint as a whole. |
I may prefer a stated cocoa percentage, but I do not want to use it as a shortcut for sugar content. Sainsbury’s lists 47% minimum cocoa solids and 49g sugars per 100g for the Lindt Excellence Dark Mint bar. |
| Allergens |
Check ingredients, highlighted allergens, free-from claims and precautionary statements on the current pack. Apply a free-from claim only to the allergens it names. |
If I need a milk-free or gluten-free product, I will check those exact claims and any other relevant allergen information. Sainsbury’s describes its Taste the Difference Free From Dark Chocolate Mints as milk and gluten free; that does not describe other dark-mint products. |
| Pack format |
Distinguish a bar, individual thins, filled mints and a multi-box pack. Check whether the pack format helps you set aside the intended number of pieces. |
For an occasional after-school treat, I would rather decide the portion than let the size of a sharing pack determine it. |
What should you avoid assuming?
-
“Dark” means low in sugar
Cocoa content and sugar content are different label figures. Waitrose & Partners lists 55% minimum cocoa solids for its Mint Thins, alongside 3.0g sugars per thin.
Compare sugars for the portion you intend to serve, as well as per 100g, instead of judging the snack by its colour or cocoa claim.
-
A sharing pack sets a suitable child’s portion
A box may contain many more pieces than you intend to serve at once. Sainsbury’s lists the After Eight nutrition figure as 17.2g sugars per three mints, making the number of pieces important to the comparison.
Set aside the intended number of pieces before serving; do not use the box size as a portion guide.
-
All dark chocolate mints have the same allergen status
The listed products differ: Sainsbury’s says its Lindt Excellence Dark Mint bar contains milk and soya, while Waitrose & Partners says its Bendicks Mint Collection may contain several types of nuts.
Read the current pack for the specific allergens you need to avoid, including any precautionary statement. A claim about one product does not apply to the category.
Relevant brand references
These examples illustrate different dark-mint formats and label details; a brand name alone does not establish the ingredients of every product it makes.
Lindt
Lindt appears here in bar and filled-truffle formats, which need different portion and label checks.
- Sainsbury’s lists 47% minimum cocoa solids for the 100g Excellence Dark Mint bar and describes its peppermint oil.
- The same listing says the bar contains milk and soya. Sainsbury’s Lindor Dark Mint listing also names milk, lactose and soya; check the specific product rather than treating the two formats alike.
After Eight
A boxed format of thin dark-chocolate mints with peppermint fondant centres.
- Sainsbury’s provides a stated nutrition serving of three mints.
- That serving contains 17.2g sugars according to Sainsbury’s; decide how many pieces to serve rather than treating the box as one after-school portion.
Waitrose
Its own-label Mint Thins offer a per-piece figure for shoppers planning a portion.
- Waitrose & Partners lists 28 kcal and 3.0g sugars per thin, with 55% minimum cocoa solids.
- The listing says the product may contain milk and nuts; check the current pack where those allergens matter.
Sainsbury’s Taste the Difference Free From
A dark-chocolate peppermint fondant mint for shoppers looking for the named free-from claims.
- Sainsbury’s describes its Free From Dark Chocolate Mints as milk and gluten free.
- Those claims do not address every allergen or determine a suitable portion; check the current pack for the child’s requirements.
Bendicks
The Mint Collection is an assorted box rather than a single-style, pre-set after-school portion.
- Waitrose & Partners lists four dark-mint styles, 50% minimum cocoa solids and suitability for vegans.
- The listing says the collection may contain almonds, hazelnuts, peanuts and other nuts.

Common questions
Are dark chocolate mints an everyday after-school snack?
They are better planned as an occasional sweet than used as the main everyday snack. NHS guidance highlights children’s sugar intake from snacks and sugary drinks; if the child is hungry, choose the main snack for that purpose and decide separately whether to serve a mint.
Does more cocoa mean less sugar in a dark mint?
No: the cocoa declaration does not tell you the sugars in a filled mint or in the portion you will serve. Waitrose & Partners lists its Mint Thins at 55% minimum cocoa solids and 3.0g sugars per thin; read both figures on the specific product’s current label.
How should I compare portions for a child?
Start with the number or weight of pieces you intend to serve, then read sugars for that portion rather than comparing unlike serving sizes. Sainsbury’s gives 17.2g sugars for three After Eight mints; NHS guidance also provides age-based daily sugar maximums, which concern the whole day rather than one snack.
Does a milk-free or gluten-free mint cover every allergy?
No. A free-from claim concerns the allergens it names: Sainsbury’s describes its Taste the Difference Free From Dark Chocolate Mints as milk and gluten free, but that does not establish their status for every other allergen. Check the current ingredients and precautionary statements against the child’s specific requirements.
