Monte Carlo biscuits are an Australian sweet biscuit that have been manufactured since 1926 by Arnott's Biscuits Holdings.
As a cream biscuit, each biscuit comprises two biscuit layers sandwiching a creamy filling, while many such biscuits are moulded to a design both sides of the Monte Carlo biscuit are rough. The biscuit layers have a mild taste of golden syrup, honey and coconut, and the cream layer consists of a vanilla flavoured cream filling sounded by a thin toffee-like coating of raspberry jam.
The Monte Carlo biscuit is available in most Australian supermarkets, being typically sold in 250g packages of 12 individual biscuits and as one of the five biscuits in the Arnott's Assorted Creams 500g variety pack. With an average mass of 20.8 grams, the Monte Carlo is the heaviest biscuit available in the Assorted Creams pack.
The biscuits were named after the city of Monte Carlo.
