Mix flour and baking powder. Add butter in flakes, egg, sugar and vanilla sugar and knead briefly. Chill for about 30 minutes. Roll out the dough on a floured work surface to a thickness of approx. 3 mm. Cut out approx. 42 flowers with a flower cutter (approx. 5 cm Ø).
Spread the flowers on 2 baking trays lined with baking paper and bake one after the other in a preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 10 minutes. Take out and let cool on a cake rack. Chop whole milk couverture and dark chocolate separately. Melt the whole milk couverture over a warm water bath, stir in the espresso powder. Use a teaspoon to blot the couverture onto 21 flower undersides. Let the chocolate coating stand for about 10 minutes. Place the remaining flowers on top. Melt the dark chocolate coating over a warm water bath. Pour the chocolate coating into a piping bag and cut off a small corner.
