Wash blueberries. Drain well in a sieve. Cream fat, vanilla sugar and 200 g sugar with the whisk of the hand mixer. Stir in the eggs one after the other. Mix flour, almonds and baking powder and stir in alternately with the yoghurt. Finally stir in blueberries. Pour the dough into a greased springform pan with a tube bottom (26 cm Ø), dusted with flour. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 50 minutes (test with sticks)
Take the cake out of the oven. After about 10 minutes, carefully turn out of the tin and let it cool down on a cake rack. In the meantime, bring frozen blueberries to the boil with 100 ml water and sugar and simmer for 6-8 minutes. Stir 2 tbsp. water with starch until smooth. Stir the starch mixture into the blueberries. Cook for about 2 minutes, remove from heat and puree finely with a blender. Let the fruit sauce cool down for about 30 minutes
Decorate the cake with the sauce and dust with icing sugar. Add the remaining blueberry sauce. Whipped cream tastes good with it
