For the light booklets, mix yeast with sugar, milk and cream until the yeast has dissolved. Add the rest of the ingredients and knead for 5-6 minutes. Let rise for about 20 minutes.
Form a roll from the dough, cut off pieces and form into balls. Place the balls in a greased baking pan and let rise, covered, for 20 minutes.
If necessary, brush the light booklets with liquid butter and bake at 190° (O/U heat) for about 20 minutes.
