Stephanie K. had cake on the brain. Tiny, elegant, orb-shaped cakes, to be precise. As she researched dessert recipes for her husband’s surprise 40th birthday party, she caught wind of the “cake ball” trend. They were everywhere. On Pinterest, on her favorite blogs, and even in wedding magazines, She knew these tiny cake nibbles would be a unique and fun addition to the party, but she also knew she’d never have the time to make them. That’s why she needed Joan C., Boston TaskRabbit and pastry dominator. Joan baked the cake, crumbled it up (we suspect this part was the most fun), mixed in frosting, rolled the dough into tiny balls, and dipped them in chocolate bark. On a separate Task for the party, Joan also helped whip up some bacon-wrapped scallops. With the fancy apps and desserts all taken care of, Stephanie had time to focus on her guests. The result? An awesome 40th birthday for a man with a very wise wife (and plenty of cake).
