Melt butter in a pot. Finely crumble butter cookies and mix well with the liquid butter. Place a springform pan rim (26 cm Ø) on a cake plate and press the cookie crumbs into the pan as a smooth base. Chill for about 30 minutes. In the meantime soak the gelatine in cold water for about 10 minutes. Put the yoghurt in a bowl. Squeeze the gelatine, dissolve it and mix with 2-3 tablespoons of yoghurt.
Then stir into the remaining yoghurt. Chill for about 10 minutes. When the yoghurt starts to gel, put the mixture on the butter biscuit base and smooth it down. Chill the cake for at least 4 hours, preferably overnight. Wash the nectarine, dab dry, cut in half and remove the stone. Cut the halves into slices. Remove the cake from the edge of the springform pan with a knife and decorate with nectarines and butter biscuit minis
