When I worked at the bank I had a customer who use to always come to my window to make his deposits for his business. He owned a bakery. He always smelled like doughnuts! lol I asked him one day if he would give me his recipe for his kuchens that he sold. He wouldn't do it till the week he decided to close his bakery and retire. This recipe makes enough for 5 kuchens. You will put a little time into this recipe till you get use to handling the dough and knowing the toppings. It's worth all your troubles. My favorite is the cinnamon or butter kuchen.
Dough- Scald milk and add butter, sugar, and salt. Dissolve yeast in warm water in seperate bowl and then add to milk mixture. Beat in eggs and then flour. Cover and let rise until doubled. About an hour. Punch down and divide into 5 pieces. Roll out into desired shape and let rise 30 minutes. Then choose your topping. I used a 9" round cake pan for mine.
Cinnamon Topping: Use a pastry blender to mix butter and brown sugar and flour. Add cinnamon and sprinkle over dough after it rises the second time. Dot with Butter if desired. Bake at 375 for 20 minutes.
Cherry Topping: Heat can of dark cherry pie filling and spread on crust after it rises second time. Bake for 20 minutes at 375.
Cheese Topping; Mix cottage cheese, egg and sugar in blender intil creamy. Heat slowly until warm on stove. Pour on dough after rises second time. Bake at 375 for 25 minutes.
Butter Topping: Beat together sugar, eggs, and vanilla. Slowly beat in oil. Add oil too fast and it will curdle. Heat on top of stove until hot and pour on crust after second rising. Bake 25 minutes at 375.
Apple Topping: Peel and slice thinly 3 apples. Sprinkle with cinnamon and sugar and nutmeg to taste. Roll this dough out in a rectangle. Fill the center with apples and dot with butter. Bake 20 minutes at 375.
