Who are these bars for?

Desk-drawer snackers

People who want a portioned sweet snack without opening a larger bag. If a separate wrapper for every bar matters, confirm that detail on the pack.

Marshmallow-centre fans

People looking for a chocolate-covered marshmallow centre rather than a crisp rice-cereal bar with marshmallow flavour.

Colleagues checking ingredients

Anyone buying for a shared snack area who needs to check the gelatine source, declared allergens and precautionary allergy advice for the exact product.

What should you check?

Decide whether you want a cereal bar or a marshmallow centre, then compare the pack format and the information given for each bar.

Priority What to check Your needs
Format and portions ASDA Groceries lists Rice Snaps as 8 × 22g bars and Kellogg’s Rice Krispies Squares as 8 × 28g bars. Tesco lists the 35g Mallow & Marsh product among single chocolate bars and sweets. Confirm individual wrapping if it is essential. I want several portions in a drawer, or I would rather pick up one chocolate-covered marshmallow bar.
Ingredients and allergens Check the current ingredients, gelatine source and allergy advice. The listed Mallow & Marsh and Kellogg’s recipes use beef gelatine; ASDA Rice Snaps lists pork gelatine. If I am sharing snacks at work, I need to know whether each colleague can eat the exact bar I buy.
Nutrition per bar Compare the serving sizes as well as the figures: ASDA Groceries lists 92 kcal and 7.4g sugars per 22g Rice Snaps bar, and 119 kcal and 9g sugars per 28g Kellogg’s bar. Mallow & Marsh lists 149 kcal and 19.1g sugars per 35g bar. I want to compare what one bar contains, while remembering that these bars are different sizes.

Common buying mistakes

  • Expecting every marshmallow bar to have the same texture

    The Mallow & Marsh product has a marshmallow centre covered in milk chocolate. The Kellogg’s and ASDA products are rice-cereal bars, so they answer a different preference.

    Choose the type of bar before comparing pack sizes: a chocolate-covered marshmallow centre or several cereal-marshmallow portions.

  • Assuming marshmallow-style bars are vegetarian

    The listed recipes contain beef or pork gelatine. That matters when buying for colleagues with vegetarian, vegan, religious or other dietary requirements.

    Read the current ingredients and allergy advice on each pack rather than relying on the product category.
