Someone looking for a plain evening treat
If you want dark chocolate with some sweetness rather than an unsweetened cocoa bar, compare plain 70–72% options. Check the exact pack for ingredients and allergens before settling on a flavour.
Who is each option for?
Someone who wants no added sugar
A 100% cocoa bar is a different taste choice from a sweetened 70% bar. Montezuma's describes Absolute Black as having no added sugar, but its pack warning still matters if you have an allergy.
Someone eating close to bedtime
Chocolate contains caffeine. If caffeine affects you or you are about to sleep, consider the timing and portion, or choose a non-chocolate light supper instead. NHS guidance also cautions that large meals close to bedtime may make falling asleep harder.
What should you check before choosing?
Choose the flavour profile first, then check the current pack for dietary suitability. For a late supper, consider timing as well as bar size.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and sweetness | Compare cocoa percentage and the ingredients. Divine and Lindt list 70% bars, while M&S lists a 72% bar; Montezuma's Absolute Black is 100% cocoa with no added sugar. | I want some sweetness with my dark chocolate, not an unsweetened cocoa bar. If I prefer intense cocoa, the 100% option is worth considering instead. |
| Allergens | Read both the ingredients and may-contain statement on the current pack. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. | For an allergy, I need the warning for this exact bar; the words ‘dark’ or ‘vegan’ cannot answer that question. |
| Bedtime timing | Consider when you will eat it and how much. Kettering General Hospital NHS Foundation Trust warns that caffeine shortly before bed can make it harder to get to sleep; NHS guidance also cautions against large meals close to bedtime. | If caffeine affects my sleep, I would rather eat chocolate earlier or choose a non-chocolate light supper. |
| Current pack | Check the label on the bar you are buying, particularly for ingredients, nutrition and allergens. Marks & Spencer advises that its online product information can change. | When a dietary detail matters to me, I want to confirm it on the pack rather than rely on an older listing. |
What is easy to overlook?
-
Assuming more cocoa means fewer allergen concerns
Montezuma's says its 100% cocoa Absolute Black bar is made without milk, but warns that it may contain traces of milk, nuts and peanuts.
If you have an allergy, use the current pack's ingredients and may-contain statement to assess the exact bar, not its cocoa percentage.
-
Equating a vegan recipe with milk-allergy suitability
Lindt says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy.
Check allergy advice separately from recipe or lifestyle labels.
-
Treating a full bar as an automatic late supper
Chocolate contains caffeine, and NHS guidance says large meals close to bedtime may make it harder to fall asleep.
If sleep timing matters to you, consider a smaller portion earlier in the evening or a non-chocolate light supper.
-
Relying on an older online description
Marks & Spencer warns that ingredient, nutrition and allergen information for its food products can change.
Read the current physical pack before buying, especially when an allergen or other strict dietary requirement is involved.

Common questions
Should I choose 70–72% or 100% cocoa for a late-night treat?
Choose a 70–72% bar if you want dark chocolate that still has some sweetness. A 100% cocoa bar such as Montezuma's Absolute Black is an unsweetened, more intense choice for someone specifically seeking no added sugar, not a like-for-like flavour substitute.
What if I want chocolate just before bed?
Consider eating it earlier if caffeine affects your sleep: chocolate contains caffeine, and Kettering General Hospital NHS Foundation Trust warns that caffeine shortly before bed can make getting to sleep harder. NHS guidance also says large meals close to bedtime may make falling asleep harder, so a non-chocolate light supper may suit you better.
Does a vegan dark-chocolate recipe rule out milk-allergy concerns?
No. Lindt says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Read the current ingredients and may-contain statement for the exact bar rather than relying on a recipe description.
Can I rely on an online listing for allergens?
Check the current physical pack before making an allergen decision. Marks & Spencer warns that recipes and product information can change, including ingredient and allergen details.
