Fill in the dough and smooth it down. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 1-1 1/4 hours. If it gets too dark, cover with parchment or baking paper. Then leave to cool in the mould for about 10 minutes. Then turn out and let it cool completely. Just before serving, first cut into approx. 8 thick slices, then cut each slice into 4 cubes. Dust with icing sugar
Waiting time approx. 1 hour
