For the choux pastry, boil 1/8 litre of water, fat and salt. Add the flour at once and stir until the dough is released from the bottom of the pot. Put the dough into a bowl and stir in an egg.
Let the dough cool down a little. Stir in the remaining eggs. Put the dough into a piping bag with a star-shaped spout and squirt it egg-shaped (approx. 7 cm long) at a large distance onto 2-3 baking trays lined with baking paper.
Bake the eggs one after the other in the preheated oven (electric oven: 225 ° C/ gas: level 4) for approx. 25 minutes. While still hot, cut across with scissors. Let them cool down. Drain the cherries and let them drain well.
Whip cream, espresso powder and sugar until stiff. Finally, sprinkle in cream firming agent. Stir in liqueur. Pour cream into a piping bag with a smaller star-shaped spout, squirt on the lower halves of the cream puffs and spread cherries on top.
Cover with the upper halves. Dust with icing sugar. Decorate with colourful dragee eggs as desired.
