Sweet crescent buns

First, mix together the ingredients for the filling. Crumble the yeast into a bowl and mix it with some of the cream until it dissolves. Add the remaining cream and the other ingredients. Roll the dough out into a rectangle on a floured work surface. Cut out triangles with a knife or a pastry wheel. Divide the filling between the triangles and roll them up into crescents. Put the crescents on a parchment-lined baking tray and let them rise until doubled in size. Brush with lightly beaten egg Bake at the centre of the oven at 225°C for approx. 8 minutes. Leave to cool on a wire rack covered with a tea towel. Dilute the icing sugar with a little water and lightly ice the crescents. The crescents freeze very well without the icing.
