This Lemon Meringue Cake combines the best elements of a classic lemon meringue pie with the elegance of a layered sponge cake. Two layers of buttery lemon sponge are sandwiched with Swiss meringue buttercream, and a zesty lemon curd filling. The cake is topped with swirls of toasted meringue for a crisp, cloud-like finish. The result is a beautifully light lemon meringue cake offering the perfect balance of sweetness and fresh zingy flavour.
