Double Chocolate Lamingtons

Lamingtons are simple sponge cakes coated in chocolate icing and sprinkled with desiccated coconut. This is a version of lamingtons made with the addition of chocolate cream. The cake is usually made with flour, dark cocoa, eggs, sugar, butter, and vanilla extract, while the chocolate cream layer consists of dark chocolate, dark cocoa, vanilla extract, icing sugar, heavy cream, and mascarpone. The regular icing is often made with icing sugar and dark cocoa. If properly prepared, double chocolate lamingtons should be moist and buttery inside and with a thick chocolate coating on the outside. Just don't show this version to lamington purists because they usually loathe variations on the original.
