Put the dough into a mixing bowl and immediately stir in 1 egg. Leave to cool for 10 minutes and stir in the remaining eggs one by one. Pour into a piping bag with a large star-shaped spout. Line two baking trays with baking paper.
Spray 6 eggs (10 cm high) onto each tray. Bake one after the other in a preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for about 20 minutes. Let them cool down.

Pour cream into a piping bag with a large star-shaped spout. Spray onto the lower egg halves. Place the upper egg halves on top.
