Banana Layer Cake with Mascarpone Frosting
The baked and cooled cake can be tightly wrapped in plastic and refrigerated for 3 days or frozen for up to 1 month. The assembled cake can be made earlier in the day and refrigerated.
Cooking Club Tip: Stick several toothpicks around the circumference where you intend to separate the cake into layers. Then with a serrated knife or piece of taut, unwaxed, unflavored dental floss, slice the cake horizontally (using the toothpicks as a guide), gently sawing back and forth to cut.
