To dream of a cupcake is lucky.

It foretells satisfaction in both social and academic/work affairs.

If the cupcake had very sweet icing, fun times are ahead for you.

Also, you may be coming into some money, or if you have a job, perhaps you’ll get a raise.

To eat a cupcake in a dream is more fortunate than to bake or buy it, although anything to do with cupcakes is lucky.
