Please make sure that all ingredients are at room temperature - they must not be too cold or too hot. The dry yeast should be stirred in well before the butter is added - otherwise the dough may not rise.
Put the flour in a bowl and make a small depression with a spoon, add the dry yeast and mix with a little flour. Add sugar, egg and salt and slowly add the milk and then the butter while stirring. Now knead into a smooth dough, cover with a tea towel and let rise in a warm place for about 1 hour until the amount has doubled.
Roll out into a large rectangle, brush with the butter, sprinkle with cinnamon sugar and nuts and roll up from the longer side. Cut into 3 cm thick slices with a very sharp knife.
Now place the individual rolls side by side in a greased springform pan. Let rise again covered for about 30 minutes.
In the meantime, preheat the oven to 200 ° C top / bottom heat. Bake the buns for about 25-30 minutes until golden brown.
If you like, you can coat the Cinnamon Walnut Buns with a frosting of 50 g cream cheese, 25 g butter, 100 g powdered sugar and possibly 1-2 tablespoons milk - it gives the whole thing an additional USA touch.
