Get your yeast going. Stir the yeast into warm milk with a pinch of sugar and wait 10 minutes until it starts to bubble.
Mix the dough. Combine the flour, sugar, salt, and cardamom in a bowl. Add in the yeast mix, egg, vanilla, and butter. Stir it all into a sticky dough.
Knead it. Work the dough for about 10 minutes until it’s smooth and elastic. Let it rise in a covered bowl somewhere warm for about an hour, until it’s doubled.
Shape your buns. Divide the dough into 10 or 12 pieces. Roll them into neat balls and let them rise again on a tray for another 30–40 minutes.
Bake. Heat the oven to 375°F (190°C) and bake until golden — around 12 to 15 minutes. Let them cool completely.
Whip the cream. Beat the cream with powdered sugar and vanilla until it’s light and holds its shape.
Assemble. Slice a “hat” off each bun, add your filling (jam or otherwise), pile in the cream, and gently top with the lid. A dusting of powdered sugar finishes it off 🎩✨
