Place one of the two choux pastries as a base in a mold or pastry ring.
Spread the vanilla cream evenly.
Carefully place the second choux pastry on top, “bumpy” side up.
Refrigerate for at least 4 hours, ideally overnight.
❄️ Step 4: Finishing
Sprinkle generously with icing sugar just before serving, to recall the snow-capped Carpathian Mountains.
