For the cookie dough, briefly mix 70 g soft butter and cane sugar with the whisks of the mixer. Add 90 g flour. Knead everything with your hands briefly to a smooth dough. Roll out between two layers of baking paper about 2 mm thin. Place in a cool place together with the paper
Meanwhile, bring 80 ml of water, milk, 75 g of butter, sugar and 1 pinch of salt to the boil for the choux pastry. Add 100 g flour. Stir with a spoon or a scraper until the dough comes off the bottom of the pot as a lump. Pour into a bowl. Whisk the eggs and stir them in bit by bit until the dough sticks to a finger. Pour the dough into a piping bag with perforated spout
Preheat oven (electric cooker: 250 °C/ circulating air and gas: not suitable!) Line two baking trays with baking paper. Spray approx. 24 choux pastry blobs (approx. 5 cm Ø each) onto the baking trays
Remove the top sheet from the cold cookie dough, put it back on top and turn the dough sheet over. Remove the paper that is now on top. Cut out approx. 24 circles (each approx. 4 cm Ø). Place the dough circles on the choux pastry blobs. Bake one after the other, but put a baking tray in the hot oven. Switch off the oven immediately. After approx. 12 minutes, turn up to 160 °C and continue baking for approx. 20 minutes. Take out the pastry, let it cool down and cut it in half crosswise.
For the filling, soak gelatine in cold water. Bring raspberry puree, egg yolk, egg and sugar to the boil in a saucepan while stirring until the mixture thickens slightly. Remove from the stove. Squeeze the gelatine. Dissolve in the hot puree. Let cool down to 35-40 °C (roasting thermometer). Gradually stir in butter with the whisk of the mixer. Chill for at least 2 hours.
Briefly whip the raspberry cream and fill into a piping bag with star-shaped spout. Spray onto the lower choux pastry halves. Sort out the raspberries and spread them on the edge of the cream. Place the upper pastry halves on top. Dust with icing sugar
waiting time approx. 2 hours
