The ingredients in McVitie’s Penguin Original biscuits include Milk Chocolate (29%), which is made from sugar, cocoa butter, cocoa mass, dried skimmed milk, dried whey, butter oil, vegetable fats (palm and shea), emulsifiers (soya lecithin, E476), and natural flavouring. The biscuit itself is made from wheat flour, calcium, iron, niacin, thiamin, sugar, vegetable oil (palm), glucose-fructose syrup, fat-reduced cocoa powder, raising agents (sodium bicarbonate, ammonium bicarbonate), natural flavouring, and salt. These ingredients come together to create a delicious, sweet snack that balances rich chocolate with a light, crunchy biscuit.
