Grease the troughs of a donut savarin dish (8 troughs, each 6.5 cm Ø) and dust with flour. Preheat the oven (electric cooker: 175 °C/circulating air 150 °C/gas: see manufacturer).
For the dough, grind 50 g nuts in the universal chopper. Cream 120 g butter and 120 g sugar with the whisk of the mixer for about 4 minutes. Stir in eggs. Mix 100 g flour, ground nuts and baking powder.
Stir into the sugar and egg mixture. Fill half of the dough into a piping bag with a medium perforated spout. Pour into the wells. Bake in a hot oven for about 15 minutes. Let it rest for about 5 minutes, then lift it out of the wells and let it cool down.
Bake the rest of the dough in the same way.
For the brittle, roughly chop 75 g nuts. Roast briefly in a pan without fat. Take out. Caramelise 50 g sugar in the pan until golden. Turn the nuts in it. Put them on a sheet of baking paper and let them cool down.
For the cream, mix cream cheese, vanilla sugar and icing sugar with whisks. Stir in yoghurt by the spoonful.
Put the cake rings together, but straighten each ring on the bottom. First spread jelly on the cut surface of 8 rings, then spread approx. 1 tbsp. cream on each ring. Place the remaining rings with the cut surface on top and press down gently.
Spread the double cake rings on the upper half all around with cream. Chill for at least 1 hour.
Roughly chop the macadamia brittle and cherries and sprinkle on the wreaths.
