What should you check before choosing?
Decide whether cocoa level, texture or ingredients matter most, then compare the exact bars and packs on that basis.
| Priority | What to check | Your needs |
| Cocoa percentage |
Look for a stated cocoa percentage on the current pack. Compare it with your chosen threshold rather than relying on the word “dark”. |
I want chocolate to be the main flavour beside tea, and a particular cocoa percentage matters to me. |
| Texture and format |
Distinguish a breakable solid bar from a wafer or filled bar. KitKat says dark chocolate covers 67.2% of its 4 Finger Dark bar; that figure describes the share of the finished wafer bar, not its cocoa percentage. |
Would I rather break off pieces over several tea breaks, or have one crisp wafer bar? |
| Ingredients and allergens |
Read the exact pack’s ingredients, allergen declarations and precautionary statements. Do not assume “dark” means dairy-free; the cited KitKat 4 Finger Dark information includes wheat and milk ingredients. |
Milk, wheat, nuts or another ingredient may affect which specific bar I can choose. |
| Type of snack |
Check whether the bar is solid dark chocolate or milk chocolate combined with caramel, nougat, peanuts or biscuit. The cited Mars, Snickers and Twix examples are milk-chocolate products. |
Perhaps I actually want a caramel-and-biscuit snack with tea rather than a cocoa-led chocolate bar. |
Brand and product-line references
These references describe particular product lines; check the exact bar rather than applying a range description to every product from a brand.
Cadbury
Cadbury presents Bournville Classic as a solid dark chocolate bar, with 100 g and 180 g formats described in the supplied product information.
- A breakable format for having pieces alongside tea or biscuits.
- Check the pack if a particular cocoa percentage matters; the cited Bournville pages do not state one.
KitKat
The 2 Finger Dark and 4 Finger Dark products are dark-chocolate-coated wafer bars, not solid dark bars.
- The 4 Finger Dark bar provides wafer crunch in a 41.5 g single-bar format.
- It includes wheat and milk ingredients. KitKat’s 67.2% figure is the proportion of the finished bar covered in dark chocolate, not a cocoa percentage.
Galaxy
Galaxy’s cited bar collection focuses on milk chocolate; its Dairy Free range is a separate alternative.
- Galaxy says the Dairy Free range is registered with the Vegan Society and made in a dairy-free and gluten-free environment.
- The Dairy Free range uses hazelnut paste and should not be treated as a plain high-cocoa dark bar; check the exact flavour and allergen label.
Mars
The cited Mars caramel bar is a filled milk-chocolate snack rather than a solid dark bar.
- Its 40 g single-bar format offers a defined filled-snack option.
- The cited product is labelled milk chocolate and does not establish a high-cocoa dark choice.
Snickers
The cited Snickers product combines peanuts, caramel and nougat with milk chocolate.
- Consider this format when peanuts and a filled bar are the intended snack.
- It is not a solid dark bar; check the exact product’s allergen information, particularly for peanuts and milk.
Twix
The Twix product described by Tesco combines biscuit and caramel under milk chocolate.
- Its biscuit-and-caramel construction is relevant when biscuit texture is the point of the tea-break snack.
- It is not a high-cocoa dark bar. Tesco advises reading the product label because formulations can change.

Questions about dark chocolate bars
Does “dark chocolate” guarantee the cocoa percentage I want?
No. A dark-chocolate description does not establish your chosen percentage; check the figure on the current pack. Cadbury’s cited Bournville product page, for instance, calls the bar dark chocolate without stating a cocoa percentage.
Is a dark-chocolate-coated wafer equivalent to a solid dark bar?
No. KitKat 4 Finger Dark contains wafers covered in dark chocolate. KitKat’s 67.2% figure describes the proportion of the finished bar covered in dark chocolate, not the cocoa percentage of a solid bar.
Can I assume a dark chocolate bar is dairy-free?
No. KitKat 4 Finger Dark includes milk-derived ingredients. If you need to avoid dairy, check the exact product’s ingredients and relevant free-from labelling rather than relying on the word “dark”.
Which allergen information should I check?
Read the current ingredients, allergen declarations and any precautionary statements for the exact bar. Food Standards Scotland says food businesses must tell consumers when their food contains any of the 14 allergens covered by UK declaration requirements.
Is an online ingredient list enough when an allergen matters?
Use the online listing to narrow your choice, then read the physical pack before eating. Tesco’s Twix listing cautions that formulations can change and directs shoppers to the product label.
