Lapis legit is a traditional layered cake originating from Indonesia, where it's been made under the influence of Dutch cuisine. The cake consists of 18 to 30 separately baked layers of egg yolks, sugar, flour, butter, and spices such as mace, nutmeg, cloves, and cinnamon.
It's essentially the Indonesian version of the European spit cake – however, it's not baked on a rotating spit, but in square-shaped baking pans. It's important not to confuse this cake with kuih lapis (or kue lapis), because lapis legit is baked and not steamed as kue lapis.
