A light and tangy lemon layer cake with fresh strawberry and blueberry filling, topped with lemon buttercream frosting. Perfect for any occasion with a fresh, summery flavor.
Use room temperature ingredients for best results. Avoid overmixing batter to keep cake tender. If berry filling is too runny, add extra cornstarch and simmer briefly. Chill frosting if too soft or add cream if too stiff. Slice domed cake tops for flat layers before assembling. Frozen berries can be used if thawed and drained well.
