If a declared cocoa-solids level matters most, Tesco’s 282 g twin pack states that its dark chocolate contains at least 48% cocoa solids, but check stock before planning your tea around it. For a shared plate, M&S offers a 250 g dark-chocolate pack; for smaller servings, Waitrose lists 125 g of mini Jaffa cakes as five 25 g servings. Neither listing gives a cocoa-solids percentage, so chocolate content and serving format are separate decisions.
If the strength of the chocolate matters to your choice, look for a cocoa-solids figure rather than relying on “dark” in the name. Tesco states a minimum of 48% cocoa solids for the dark chocolate in its 282 g twin pack; check availability before choosing it for a particular date.
M&S describes its 250 g Dark Chocolate Jaffa Cakes as suitable for sharing. The boxed format may suit a communal plate, provided the exact product is in stock and its allergen information suits your guests.
Waitrose lists five 25 g servings in its 125 g Mini Jaffa Cakes pack. Mini cakes may fit alongside other items on the table, but check the exact pack’s ingredients and allergen advice before serving.
Decide whether the chocolate’s declared cocoa content, the way you will serve the cakes or guests’ dietary requirements will determine the pack you buy.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa content | Look for a cocoa-solids percentage for the chocolate itself. Tesco states at least 48% cocoa solids for the dark chocolate in its 282 g twin pack. A percentage of dark chocolate in the whole cake measures something different. | “Dark” alone does not tell me the cocoa-solids level. If a declared figure is essential, I’ll check the exact pack and confirm that Tesco’s twin pack is in stock. |
| Serving format | M&S lists a 250 g pack described as suitable for sharing. Waitrose lists five 25 g servings in its 125 g Mini Jaffa Cakes pack. Check how many packs you want alongside the rest of the spread. | For a shared plate, I may prefer a larger box. If guests will take smaller portions among other foods, mini cakes make more sense for my table. |
| Allergens | Read the ingredients and precautionary statements on the exact pack. M&S says its Dark Chocolate Jaffa Cakes are not suitable for people with nut or peanut allergy; other products have different allergen statements. | I need to know whether each guest can have the particular cakes I’m serving, rather than assuming all Jaffa cakes have the same ingredients. |
“Dark chocolate” identifies the coating, but it does not by itself give its cocoa-solids percentage. A figure for how much of the cake is chocolate answers a different question.
If cocoa content matters to your choice, look for a cocoa-solids statement on the exact version you intend to buy.
Tesco’s listing for the twin pack with a declared 48% minimum cocoa-solids level was marked out of stock when reviewed. Its stated specification does not establish that you can buy it for your event.
Check availability close to the party and decide whether a sharing pack or mini cakes would meet your serving needs if it is unavailable.
Ingredient and precautionary statements differ between the Tesco, M&S, Waitrose, ASDA and McVitie’s products described here. M&S specifically says its Dark Chocolate Jaffa Cakes are not suitable for people with nut or peanut allergy.
Read the physical pack you will serve and arrange a suitable alternative where a guest’s requirements call for one.

The 330 g triple-pack format is an option for setting out cakes to share at afternoon tea. McVitie’s states that dark chocolate makes up 19% of its Original Jaffa Cakes; this is not a cocoa-solids figure. Check the exact pack’s allergen advice before serving.

The box contains 80 cakes and weighs 1.07 kg, a format to consider when planning for a larger group. Do not use the count alone to judge how many guests it will serve; that depends on what else is on the table. Check the exact pack for cocoa-solids and allergen information.

Six packs of three cakes offer individual packs for a mixed afternoon-tea spread rather than one large shared box. The total weight is 198 g. Check the exact pack’s chocolate and allergen statements if either affects your choice.

No. “Dark chocolate” identifies the coating but does not give a cocoa-solids percentage. A statement that chocolate makes up a certain percentage of the cake also measures something different; check the chocolate’s cocoa-solids figure if that matters to you.
Do not assume that any dark Jaffa cake is suitable. M&S says its Dark Chocolate Jaffa Cakes are not suitable for people with nut or peanut allergy, and statements differ between products. Read the label on the exact pack before serving and provide an appropriate alternative where needed.
