For the BrandTeig, bring butter, salt, milk and 1⁄8 l water to the boil until the butter has melted. Add the flour at once and stir with a wooden spoon until a white layer forms on the bottom of the pot and the dough comes off the bottom as a dumpling.
Put the dough into a bowl and immediately stir in 1 egg, let it cool down for about 10 minutes.
Stir the remaining eggs into the dough one after the other. Pour the dough into a piping bag with a large star-shaped spout and squirt approx. 16 tuffs (each approx. 6 cm Ø) onto two baking trays lined with baking paper.
Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 25 minutes in succession (do not open the oven door!). Cut the cream puff horizontally. Let them cool down.
Defrost the raspberries for the filling. Mix cream stiffener with sugar and vanilla sugar. Whip cream with it until stiff. Stir raspberries briefly with a whisk and fold into the cream. Fill raspberry cream into a piping bag with a large star-shaped spout.
Spray onto the lower halves of the dough. Place the lid on top and dust with icing sugar.
