In a mixer add yeast, warm water, and sugar. Combined and let sit for 10 minutes. Then add salt, eggs, oil, and 5 cups of flour. Mix for 5 minutes on medium speed. Then add another 5 cups of flour and mix for 5 to 7 minutes on medium speed. Then let rise 1 hour. Roll dough into a rectangle on a floured board and spread with butter, sugar, brown sugar, and cinnamon. Roll together and slice individual roll slices and place into a well greased or sprayed pan. Cover with thin cloth. Let rise for 8 hours on your kitchen counter. Bake at 350 degrees for 12-15 minutes. Let sit for a few minutes then frost them.
Mix together all ingredients. Add milk if you need to thin the icing while mixing.
