This recipe is perfection for chocolate enthusiasts: it’s not too sweet, and it has a truly dreamy melt-in-your-mouth texture. This cake hails from the northern Italian city of Bologna, and while it may look similar to its southern Italian counterpart, Torta Caprese, it has a unique personality of its own. In a recipe this simple, it’s all about the quality of ingredients. Use good chocolate bars (we love Guittard or Ghirardelli) and splurge on some great European-style butter. The real secret to the soft texture of this cake is the potato starch; it takes it to a new level.
