How to make
For the syrup, put the sugar and water on the stove. Leave it to boil for 2-3 minutes and remove it from the heat. Place the cake layer in a springform pan and use a spoon to pour the syrup over it.
To prepare the eclairs, mix the water, salt and butter in a saucepan. As soon as the liquid boils, remove from the heat and pour the flour all at once. Stir until the liquid absorbs the flour.
Place it back onto the heat and stir for another 3-4 minutes until the mixture forms a ball. Remove from heat and leave it to cool slightly. Add the 4 eggs to the chilled dough. Add them one by one, stirring after each egg until it is absorbed.
Line a tray with baking paper and using 2 tsp. form the eclairs, spacing them apart. Bake the eclairs at 170°C for 30 minutes, without opening the oven during this time. After this time is up, you turn off the oven and open it a little. Leave the eclairs for 5 minutes inside and then take them out. Let them cool.
Start preparing the cream for them. Put the milk and sugar on the stove. As soon as it starts to boil, reduce the heat. Mix the flour with a little water and pour it into the milk in a thin stream, stirring continuously until a thick cream is obtained.
Remove it from heat and leave it to cool slightly. Add the vanilla, egg yolks and mix. Allow the finished cream to cool completely. Make a small slit in each éclair and use a small spoon to fill them.
For the cream, beat the yogurt with the sugar. Separately, beat the cream. Add it to the yogurt in parts, by stirring with a spatula. Prepare the gelatin according to the instructions on the package and add it to the mixture. Stir again and begin assembling the éclair cake.
Arrange eclairs on top of the syrupy cake layer. Cover with half of the cream and arrange again from the eclairs. Leave 5-6 eclairs for decoration. Pour the remaining cream on the second row of eclairs.
Refrigerate overnight. Release from the springform pan ring and decorate with the rest of the eclairs. In a water bath melt the chocolate in the cream. Wait for it to cool slightly and pour it over the cake.
