A showstopping holiday dessert that's a piece of cake? Meet this four-layer chocolate confection, which comes together from a one-bowl batter and three-ingredient frosting. Coconut oil gives it an especially tender crumb and keeps it so moist, you can bake it days in advance. A tangy raspberry jam between each layer makes it even more extraordinary. Not to mention it's dairy-free, too, with almond milk in the batter and coconut milk in the frosting, so it's a fabulous final act for a kosher meal.
