Cadbury Brunch Oats Bar Peanut Chocolate Cereal Bar nutrition

One bar (28g)Ultra-processed (NOVA 4)4 allergensNPM Score (2018): 17, higher is less healthy

Figures from Cadbury UK product page, collected by Boone. Free sugar estimated by Boone. Last checked 26 October 2026. Data checks are led by Murray Dare.

Brunch bars are now 28g. Cadbury’s per bar figures still fit an older, larger bar, so Boone uses the per 100g figures for a 28g bar. Free sugar leaves out an estimated 1g of lactose per 100g, worked out from the 19% chocolate on the label at the legal minimum of 14% milk solids, so the real amount of lactose is likely higher. Lactose is the sugar in milk and is not free sugar.
