Put the baking mixture into a mixing bowl and spread the butter in small pieces on top. Add the eggs and work into a smooth dough with the dough hooks of the hand mixer. Knead briefly with floured hands and roll out on a floured work surface.
Cut into strips of approx. 3.5 cm wide using a wavy pastry wheel. Repeat this diagonally once more, so that rhombuses are formed. Arrange the rhombs on 2-3 baking trays lined with baking paper.
Mix egg yolk and cream and brush the rhombs with it. Place about 1/2 teaspoon of poppy seed mixture in the middle of each rhombus. Halve the cherries and press 1/2 cherry on each poppy seed blob. Bake the trays one after the other in a preheated oven (electric: 175°C / gas: level 2) for 8-10 minutes.
Let the cookies cool down on a cake rack. Makes about 60 pieces.
