There are so many recipes for swedish kanel bullar if you just google it.
But I bake them at least once a week so i decided to change the dough and I am using a simple bread dough it works just well for my children.
For one baking pan I use:
500 gr. all purpose flour
250 ml. warm water
2 tablespoons olive oil
1 teaspoon sugar
1/2 teaspoon salt
1 teaspoon dry yeast
1 teaspoon baking powder
Make a soft dought from this. Add some flour if needed. Cover it with clean warm towel and leave it at least for an hour to rest and raise.
Then devide it in two.
Take one ball, put it on a floured surface, sprinkle more flour on the top and start working with the rolling pin. Open it in a rectangular shape spread some soft butter sprinkle brown sugar and cinnamon and roll it. Cut smal buns and line them in the baking pan. Let them rest for half an hour then Brush risen bullars with egg and sprinkle some sugar or almonds or sesame seed and bake for 10 minutes on 200 degrees celsius.
