When Jennie Carter excitedly set out to bake a cake celebrating her child's first birthday, it didn't turn out so well. The debacle inspired her to take some cake-decorating classes, and she unearthed a talent that led to the creation of Tiers from Heaven, a one-woman baking business that deals exclusively in special orders for cakes, cupcakes, and cookie cakes from inside a mobile truck. The lineup of more than 30 cupcake flavors includes the Blue Hawaiian, a pineapple-rum cake on which a cherry and a dried pineapple wedge float on a swell of Blue Curacao frosting.

Since overcoming her failed birthday-cake attempt, Jennie's successes range from opening her own food truck to wowing July 4 partygoers with cake pops draped in American-flag designs. She also baked a camouflage-frosted cake to sweeten a soldier's welcome-home festivities, much to the despair of forks that kept losing sight of their target.
