This recipe was the 2002 winner at the Iowa State Fair.
To make dough:
Cream butter, sugar and salt together using an electric mixer. Stir in egg. Add 2 cups flour and yeast. Pour water in all at once and mix.
Gradually add 1-3/4 cups flour to make a soft dough. Knead 5 minutes on lightly floured surface. Place dough in a greased bowl. Cover and let rise until double, about 45 to 60 minutes.
Punch down and roll out dough to a 18 x 10-inch rectangle. Brush dough with 3 tablespoons melted butter. Mix sugar and cinnamon together and sprinkle entire amount evenly over dough.
Roll up from long side; seal edges. Cut roll into 12 slices. Using three greased 8-inch square pans, place 4 rolls per pan, cut side up. Cover and let rise until double, about 45 minutes. Bake at 350ºF for 16 to 18 minutes. Cool.
For Frosting:
Mix powdered sugar, vanilla and enough cream to make icing of pouring consistency. Drizzle frosting evenly on all rolls.
