Oreo cookies are made up like a sandwich having two outer chocolaty brown biscuits and in the middle is the vanilla flavoured thick cream. Nowadays, strawberry and mango flavoured cream is also abailable in oreo cookies which makes it my favourite.
If we eat the biscuit alone then it would taste chocolaty but little bitter but when we eat with the cream , it gives us a taste of brownie. Nowadays oreo icecream is also available where oreo biscuit pieces are added to vanilla icecream.
