Claire Saffitz brings a tropical twist to a classic layer cake with this Coconut Cake featuring rich, silky German buttercream. Made with full-fat coconut milk, toasted coconut flakes, and a light, fluffy sponge, this cake strikes the perfect balance of flavor and texture. The German buttercream, made with a pastry cream base and whipped butter, adds an ultra-smooth finish without being overly sweet. This is a special-occasion cake that feels timeless and fresh all at once.
