The inspiration from this cake came from Tartine's pumpkin tea cake. I wanted to make a lighter, cake-ier cake, closer to a dessert you'd eat at a dinner party than to a quickbread you'd eat for breakfast. The frosting recipe is based on my idol Dorie Greenspan's Tangy Cream Cheese Frosting.
These layers of sweet potato cake with marshmallowy meringue icing in between and a topping of praline and candied pecans will make a spectacular finish to any feast.
These are the richest brownies I have ever eaten. They do not need any frosting; actually, it would just be gilding the lily. They are pretty good with walnuts though.
