Shoppers looking for a high cocoa percentage
If a darker-sounding name is not enough, compare the declared cocoa solids and sugars per 100g. Lindt lists 70% minimum cocoa solids for Excellence Dark 70%; Cadbury Darkmilk lists 38% minimum.
Who is choosing a late-night chocolate bar?
People eating close to bedtime
If caffeine affects your evening routine, consider whether chocolate belongs in a snack just before bed. Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust includes chocolate among the caffeine sources it advises limiting or avoiding before bedtime.
Shoppers planning a portion
A single bar and a larger bar divided into portions invite different choices. KitKat lists its 4 Finger Dark as a 41.5g bar; the Cadbury Darkmilk 90g listing describes three portions.
What should you check before choosing?
Start with the cocoa declaration, then check the amount you intend to eat, the ingredients and how soon you plan to go to bed.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and sugars | Read the cocoa-solids declaration; compare sugars on the same per-100g basis. Lindt lists 70% minimum cocoa solids and 29g sugars per 100g for Excellence Dark 70%, while the Cadbury Darkmilk 90g listing gives 38% minimum and 49g sugars per 100g. | I want a stated high cocoa percentage, rather than relying on the word “dark” in the name. |
| Bedtime timing | Consider when you will eat the chocolate and your response to caffeine. Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust advises limiting or avoiding caffeine, including chocolate, before bed. | If I am going to bed soon, a chocolate bar may not fit the evening routine I am trying to keep. |
| Portion format | Check bar weight, portions per pack and nutrition per serving. KitKat lists 4 Finger Dark as one 41.5g bar with 208 kcal per serving; the Cadbury Darkmilk 90g listing describes three portions. | A defined single bar might suit me, or I might prefer to divide a larger bar across occasions. |
| Ingredients and allergens | Read the exact pack’s ingredients and allergen statements. KitKat 4 Finger Dark contains wheat and milk; Lindt says Excellence Dark 70% may contain nuts, milk, soya and sesame and is not suitable for people with a milk allergy. | Before choosing a dark-labelled bar, I need to know whether its wafer, milk ingredients or allergen warnings matter to me. |
What can be easy to overlook?
-
Assuming every “dark” bar is high in cocoa
The formats differ: Lindt lists 70% minimum cocoa solids for Excellence Dark 70%, while the Cadbury Darkmilk 90g listing states 38% minimum.
Use the cocoa-solids declaration on the current pack if a high percentage is your deciding factor.
-
Treating chocolate as a bedtime snack without considering caffeine
Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust names chocolate among caffeine sources to limit or avoid before bedtime.
If you are eating just before bed or are sensitive to caffeine, consider a non-chocolate option or have the chocolate earlier.
-
Equating a vegan recipe with milk-allergy suitability
Lindt says Excellence Dark 70% is made to a vegan recipe but is not suitable for people with a milk allergy because it is made in a facility that uses milk.
For a milk allergy, follow the exact product’s allergy suitability statement and current pack declaration rather than the vegan-recipe wording alone.
-
Overlooking wafers, nuts and fillings
A dark-chocolate coating does not describe everything inside a bar. KitKat 4 Finger Dark contains wheat and milk, while different bars carry different ingredient and precautionary allergen statements.
Check both the ingredients and any “may contain” wording on the exact flavour and pack you intend to buy.
Which brands illustrate the different formats?
These named products show why a plain dark bar, a wafer and milk-chocolate alternatives should be assessed by their own labels, not by brand name alone.
Lindt
The Excellence Dark 70% bar is a plain, high-cocoa example for comparing cocoa and per-100g nutrition declarations.
- Lindt lists 70% minimum cocoa solids and 29g sugars per 100g for this bar.
- Lindt says it may contain nuts, milk, soya and sesame, and is not suitable for people with a milk allergy despite its vegan recipe.
Cadbury
Darkmilk is a milk-chocolate alternative for someone considering a more cocoa-led flavour without choosing a plain 70% dark bar.
- The Cadbury Darkmilk 90g listing states 38% minimum cocoa solids and three portions.
- The listing gives 49g sugars per 100g, identifies milk and soya, and says the bar may contain almonds and hazelnuts.
KitKat
4 Finger Dark is a dark-chocolate-coated wafer for someone choosing a defined individual bar rather than plain dark chocolate.
- KitKat lists a 41.5g bar, with 208 kcal and 18.6g sugars per serving.
- Its wafer contains wheat, and its ingredients include milk.
Galaxy
Galaxy’s listed milk chocolate provides a point of comparison for shoppers deciding whether they want a dark bar at all.
- The Galaxy Gift Milk Chocolate Bar listing states 25% minimum cocoa solids.
- That milk-chocolate listing gives 54g sugars per 100g and includes milk and soya ingredients; it is not a high-cocoa dark-bar example.
Snickers
The listed 40g Snickers is a peanut, caramel and milk-chocolate alternative, not a plain dark bar.
- Snickers lists a 40g bar and 20g sugars per bar.
- Its ingredients include peanuts, milk and egg white powder, and the label says it may contain other nuts.

Tony's Chocolonely Dark Chocolate, Almonds & Sea Salt 180g

This 90g bar combines a stated 70% dark chocolate with raspberries. Its product information gives conflicting milk and vegan descriptions, so check the current pack before relying on either dietary or milk-allergy suitability statement.
Questions about late-night chocolate
Is high-cocoa dark chocolate a good choice immediately before bed?
If you are limiting caffeine before bed, chocolate does not fit that aim. Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust names chocolate among caffeine sources to limit or avoid before bedtime; that guidance does not mean every bar affects every person in the same way.
Does “dark” in a bar’s name mean it has a high cocoa percentage?
No: check the declared cocoa solids on the exact product. Lindt Excellence Dark 70% lists 70% minimum cocoa solids, whereas the Cadbury Darkmilk 90g listing states 38% minimum.
Can I rely on a dark bar’s vegan-recipe wording if I have a milk allergy?
No. Lindt says Excellence Dark 70% is made to a vegan recipe but is not suitable for people with a milk allergy because it is made in a facility using milk. Follow the exact bar’s current allergy suitability statement and pack declaration.
Is a dark-coated wafer bar the same choice as plain dark chocolate?
No. KitKat 4 Finger Dark is a 41.5g wafer bar coated in dark chocolate, rather than a plain 70% cocoa bar; its ingredients include wheat and milk. It may suit a preference for an individual wafer bar, but check its ingredients if those allergens matter to you.
