No and one is sufficient.
Did your mom or grandmother use 2 cupcake liners per cupcake? If I have the flimsy papers then I still use two - what's your technique?
They never used 2 and either did I. One is always sufficient. Maybe you need to look into better quality liners if you have a problem.
I only used two for presentation. If it's for my little family, I use one. If I'm making them for a school function, or a team, holiday, or bake sale, I'll use two. They look really nice that way.
