Cinnamon roll cake

• Dissolve the yeast in the lukewarm milk – add the egg and sugar and stir briefly to combine.
• Add the cardamom and salt together with a little of the flour, then stir in the remaining flour a little at a time until all of it is incorporated into the dough.
• Add the butter in small pieces and knead the dough thoroughly, ideally in a stand mixer, until it comes away cleanly from the sides of the bowl – this takes about 5-8 minutes on medium speed.
• Oil your hands lightly, take the dough out and shape it into a taut ball by folding the edges under. Lightly oil the proving bowl as well, return the dough to it, cover the bowl with cling film and a tea towel, and leave to rise in a warm place for about 1 1/2 hours.
• Meanwhile, mix the ingredients for the remonce and leave it on the worktop at room temperature.
• Take the dough out of the bowl, dust the worktop with a little flour and gently stretch the dough into a small square. Roll the dough out into a rectangle of about 60x30 cm. Use as little extra flour as possible when rolling, but of course make sure the dough does not stick to the worktop.
• Spread the remonce over the whole surface – use a palette knife or your fingers. Leave a 1 cm strip along one long edge free of remonce – this helps the roll seal better.
• Roll the dough up from one long edge towards the other, so you end up with a long log of about 60 cm.
• Cut the log into 14 cinnamon rolls – each should be about 4 cm wide.
• Line the base of a springform tin with baking parchment, and grease both the base and the sides generously with butter.
• Arrange the cinnamon rolls in the tin – start with a row of 3 along one side, then 2 rows of 4, and a row of 3 on the other side.
• Cover the cake with a tea towel and leave it to prove again for about 30 minutes.
• Brush the cake with the beaten egg and bake in a preheated conventional oven (top and bottom heat) at 200°C for about 22-25 minutes.
• Let the cake cool slightly before opening the springform tin.
• Once the cake has cooled completely, stir the icing together and drizzle it over the cake.
