For the nut cake, separate eggs. Beat yolks and butter with honey and rice sweetener, add cinnamon and clove powder. Mix flour with baking powder, add nuts.
Whip egg whites with salt until very stiff. Using a spatula, carefully fold all the ingredients together, pour into a greased, floured tin (loaf pan) and bake at 170 degrees hot air for about 45 minutes.
Test with chopsticks. Turn the cake out of the pan and let it cool. Then cut in half and fill with apricot jam or jam.
