Who is this for?

Hosts putting together adult party favours

Sealed pieces are easier to hand out than portions broken from a bar. Hotel Chocolat described an individually wrapped 70% dark Halloween product in its 2025 seasonal material; check the current item and label before planning around that format.

Hosts serving guests with different dietary needs

A vegan-labelled recipe and an allergy warning answer different questions. The cited Divine, Lindt and Montezuma's dark chocolates carry product-specific precautionary warnings, including warnings about milk or nuts. Ask guests what they need to avoid and retain the packaging for each chocolate you serve.

Hosts making a dessert table or party bake

Bars can be broken into portions or used in a recipe, while buttons can be served in a bowl. Lindt describes its examined 70% bar for cooking, and Montezuma's presents its 74% buttons as a sharing format; check the ingredients of the exact product chosen.

What should you check?

Start with how guests will take or use the chocolate, then check the cocoa level and the label of each exact product.

PriorityWhat to checkYour needs
Serving format Check whether pieces are individually wrapped, loose buttons, a bar or filled chocolates. Confirm the pack format rather than assuming a box contains sealed portions. I want guests to take a sealed favour, or I need chocolate I can put out on a sharing table or use in a bake.
Cocoa and flavour Read the stated cocoa percentage and whether the chocolate is plain, flavoured or filled. A percentage alone does not tell you whether every guest will enjoy it. Some guests already enjoy strong dark chocolate; others may prefer a different flavour or a less intense option.
Ingredients and allergens Read the current ingredients and precautionary allergen statement for every exact product, including each filling in an assortment. Do not use a vegan label as evidence that a product is suitable for a milk allergy. I need to know what guests must avoid before putting chocolates in a communal bowl or serving a dessert.
School-event setting Establish whether food is being provided under school-food standards. The Requirements for School Food Regulations 2014 define chocolate as confectionery for their England-specific provisions; confirm the applicable arrangement with the school or caterer. If I am organising food through a school in England, I need to check its requirements before choosing party treats.

Mistakes to avoid

  • Assuming dark or vegan means allergy-suitable

    Lindt says its examined Excellence 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. The cited Divine and Montezuma's products also carry precautionary allergen wording.

    Ask about guests' allergies before buying, check each current pack and keep its label available when serving.

  • Judging a seasonal chocolate by its packaging

    A Halloween collection can contain different chocolate types and recipes. Its theme does not establish the cocoa percentage or dietary suitability of an individual item.

    Check the named product, cocoa percentage, ingredients and allergen statement rather than relying on the collection name or box colour.

  • Treating bars, buttons and filled chocolates as interchangeable

    Buttons suit a sharing bowl, while a bar can be broken up or used in a recipe. A filled selection can introduce ingredients that are not in a plain bar: the cited M&S dark selection contains milk and hazelnuts.

    Choose the format for how you will serve it, then check every recipe in an assortment against the guest list.

Questions about serving dark chocolate

Is 70% dark chocolate a sensible party choice?

It can be a starting point if guests already enjoy dark chocolate. Divine and Lindt both list 70% bars, but flavour preference varies; check the exact recipe and offer another option if you are serving people who may not want dark chocolate.

Is vegan dark chocolate suitable for someone with a milk allergy?

Not necessarily. Lindt says its examined Excellence 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Read the current pack's ingredients and precautionary statement for every exact product.

What if the Halloween event is at a school in England?

Check whether the food is being provided under school-food standards before choosing chocolate. The Requirements for School Food Regulations 2014 define chocolate as confectionery for their England-specific provisions, while Department for Education guidance explains that school food standards govern what is served and how often. Confirm the event arrangements and applicable requirements with the school or caterer; this is not a conclusion about private parties or schools elsewhere in the UK.

How should I store the chocolate before the party?

Follow the directions and best-before date on each exact pack. The cited M&S dark bar calls for a cool, dry place away from sunlight; a filled or seasonal product may give different instructions.

Is an online ingredient list enough when a guest has an allergy?

Use the current pack as the final label check. M&S advises customers to read product labels because ingredients and allergen information can change; ask the guest about their requirements before selecting what to serve.
