Line the bottoms of two springform pans (26 cm Ø) with baking paper. Beat butter and 120 g sugar with the whisk of the hand mixer until foamy. Separate the eggs, stir in the egg yolks one after the other. Mix flour and baking powder, stir into the dough. Put half of the dough into each springform pan and spread evenly.
For the meringue, beat the egg whites with 225 g sugar until stiff. Spread half of the mixture on each of the doughs and sprinkle each with 75 g flaked almonds. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 25-30 minutes, remove and let cool. Remove the edges of the springform pan from the cakes and let them cool completely on a cake rack.
For the filling, drain the cherries and collect the juice. Bring half of the juice to the boil in a saucepan, thicken with cake glaze, add the cherries again and chill. Mix the cream, vanilla sugar and cream setting agent, beat until stiff with the whisks of the hand mixer. Place one of the two bases on a cake plate. Place a thin layer of cream on top. Cover with cherries, spread the remaining cream on top and place the second cake layer on top.
