A poorly frosted cake is a tragedy in The Martin Agency's new ad for Cool Whip. "Mistreated Cakes," which breaks today and pushes Cool Whip Frosting, plays out like a PSA on behalf of the "millions of innocent cakes [that are] mangled, mistreated and hurt" by rival frostings, which just aren't as smooth. Images of sloppy cakes give way to a shot of a supermarket freezer full of Cool Whip Frosting, as a plaintive male voice explains, "There is something you can do." After a lush close-up of Cool Whip Frosting being spread on a chocolate cake, the ad shifts back to a sad sack of a birthday cake just as one of its candles topples over. "Please help," implores the voice, amid sparse piano notes. "Cool Whip Frosting. Together, we can change the way cakes are frosted." Martin senior copywriter Bob Meagher said the mock-PSA approach stemmed from a simple idea: What if a cake had feelings? To get the mood right, Meagher and senior art director Pat Wittich watched old PSAs and, yes, baked a cake. The ad, which targets moms whose families bond over dessert, will run through May during shows such as Food Network's Cupcake Wars and ABC's Grey's Anatomy, according to Marjani Coffey, brand manager on Cool Whip at Kraft Foods.
