Sugar
Fox's Burton's Companies Rocky Chocolate Bar contains 8g of free sugar per piece. Each piece weighs 24.5g. Two pieces deliver 16g of free sugar and 234 calories. The Rocky bar combines a thick biscuit with a chocolate cream filling and a milk chocolate coating. It is one of the larger individually wrapped biscuit bars available in the UK.
All added sugar in Rocky Chocolate Bar counts as free sugar under NHS guidelines. Sugar from jam, chocolate, caramel, fondant or iced toppings all counts in the same way as sugar added to the biscuit dough itself.
At 8g per piece, Rocky Chocolate Bar is among the higher-sugar options in this guide. Two pieces deliver 16g of free sugar, which is 84% of the daily limit for a child aged 4 to 6 and 67% for a child aged 7 to 10.
Because each Rocky Chocolate Bar is a single 24.5g piece rather than a small biscuit, it is realistically eaten one or two at a time rather than three or four. The figures in this guide use two as the reference quantity for that reason.

Saturated fat
Rocky Chocolate Bar contains 2.7g of saturated fat per piece. Two pieces deliver 5.4g of saturated fat, 27% of the adult daily guideline of 20g.
The saturated fat content is moderate for a biscuit. As with most biscuits, the fat comes from vegetable oil used in the dough and any chocolate or cream components.
Recommended daily maximum saturated fat intake
Age 4 to 6No more than 10g per day
Age 7 to 10No more than 13g per day
Age 11 to 17No more than 17g per day
AdultNo more than 20g per day

Fibre
Rocky Chocolate Bar contains 0.5g of fibre per piece. Two pieces provide 1g of fibre, a small contribution toward the adult daily target of 30g.
Most biscuits made from refined flour are low in fibre. If increasing fibre intake is a priority, oat-based or wholegrain biscuits typically offer more.
Protein
Rocky Chocolate Bar contains 1.3g of protein per piece. Two pieces provide 2.6g of protein. Biscuits are not a significant protein source; protein in a child's diet comes primarily from dairy, meat, fish, eggs and pulses.

Adult fibre target: 30g per day (SACN). Child protein target shown: 24g per day (guide for a 7 to 10 year old).
Whole grain and processing
Rocky Chocolate Bar is made from refined flour, and falls into NOVA group 4 under the food processing classification system used in nutrition research.
Whole grain
Rocky Chocolate Bar is made from refined flour rather than whole grain. This is typical of most biscuits and is reflected in the low fibre content of 0.5g per piece. The bran and germ layers of the grain that contain most of the naturally occurring fibre are removed during the refining process.
Processing (NOVA classification)
Rocky Chocolate Bar falls into NOVA group 4, ultra-processed foods. This reflects the combination of refined ingredients, added sugar, flavourings, and industrial processing methods used to produce the final product. The NOVA group 4 classification applies to the vast majority of packaged biscuits, regardless of whether they contain wholegrain ingredients.
Salt
Rocky Chocolate Bar contains 0.13g of salt per piece. Two pieces contain 0.3g of salt. Salt is not the primary nutritional concern for most biscuits; the sugar and saturated fat content are more significant.
