Beat the egg whites with one-third of the sugar and, in a separate bowl,
beat the egg yolks with another third. Soften the butter and cut into small
pieces, them mix this with the remaining sugar and beat until light and
creamy. Place the three mixtures into one large bowl, add the flour and
vanilla extract and blend thoroughly.

Transfer two-thirds of the mixture to another bowl and to this add the
cinnamon, nutmeg, and allspice powder and stir to blend well.

Pour one-third of the spiced mixture into a well-greased cake tin and bake
in a moderate oven until firm, then add half the plain mixture and bake
until this is also firm. Repeat the process three more times; spiced,
plain, and ending with spiced. Turn out onto a wire rack and allow to
cool before serving.
