Caramel squares (alternatively: caramel slices, caramel shortbread, or millionaire's shortbread) are a wonderfully rich and classic treat, very popular all over Britain and Ireland. They can often be found in cafes, served with morning coffee or afternoon tea. They're perfect for picnics, lunches and your guests will love them! They have a crunchy base with a creamy caramel filling, topped off with chocolate.
