Bring milk, 1/8 litre water, salt and butter to the boil in a saucepan. Add the flour at once and stir with a wooden spoon until the dough separates as a lump from the bottom of the pot. Stir in 1 egg, allow to cool for 10 minutes, add the remaining eggs one after the other.
Put the choux pastry into a piping bag with a large star-shaped spout and squirt 12 cream puffs (3 cm wide each) onto a baking tray (approx. 32 x 37 cm) lined with baking paper. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 25 minutes.
Remove and let it cool down. Whip the cream until stiff, allow the cream setting agent to trickle in. Select the raspberries and puree with sugar, pass through a sieve. Add the raspberry puree to the cream, marble briefly with a fork.
Cut the cream puff in half horizontally. Spread raspberry cream on the lower halves, place the lid on top. Dust with icing sugar.
