Squeeze the apricots slightly flat and cut out small stars (2.5 cm Ø) with a mould (32 stars approx. 100 g). Finely grind the almonds. Pass the icing sugar through a sieve.
Beat the egg whites with the whisks of the hand mixer until stiff. Stir in icing sugar by the spoonful. Take off approx. 50 g of beaten egg white for spreading. Stir almonds, vanilla sugar, cinnamon and bitter almond oil into the remaining beaten egg whites.
Dust a work surface with icing sugar and roll out the dough about 1/2 cm thick. Cut out squares of about 5x5 cm and halve them diagonally. Spread them on a baking tray lined with baking paper and brush with the egg whites that have been put aside.
Decorate each triangle with an apricot star. Bake in the preheated oven (electric oven: 150 °C/ gas: level 1) for 18-20 minutes. Let cool on a cake rack. Results in about 32 corners.
