Yo Yos

If you’re not yet familiar with Yo Yos (otherwise known as Whoopie Pies, Black Moons, Gobs, or BFOs), you’re in for a real treat. Yo Yos yield a perfect cake-to-frosting ratio in an easy-to-devour format. A classic buttercream with a dash of lemon zest goes perfectly with the chocolate, offering a clean, crisp flavor complement to the dark, rich cake. If you’re looking for a chocolate dessert for a summer picnic, this is it. Really love buttercream? Double the recipe and add as much filling
