Frosting dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.

Interpretation 1 — Patrica Telesco

(see Baking, Cake, Eating)

Glossing over the surface of a matter without really digging down to get the full story.

The little serendipitous bonuses in life, like the icing on a cake.

The sweetness of the frosting gives it some meanings similar to candy.

A decorative facade that won’t hold up under detailed scrutiny.

Interpretation 2 — Stearn Robinson - Tom Corbett

A dream which especially features the frosting and not the cake is a reminder that you can lose out on some of the basic satisfactions if you concentrate on grasping at the transitory pleasures.
