2 c. boiling water
2 sq. butter
1 c. sugar
1 T. salt
2/3 c. powdered milk
1 c. warm water
1/2 tsp. sugar
3 T. yeast
6 beaten eggs
12 c. flour
Mix in a large stand electric mixer with dough hook attachment.
Pour boiling water over sugar and butter in a large stand mixer bowl. Stir until butter is melted. Cool slightly, then add the salt and powdered milk. Meanwhile, mix the 1 c. water, 1/2 tsp. sugar and yeast in a small bowl. Allow yeast to bubble. Add the yeast mixture to the first mixture along with the eggs and 5 cups of the flour. Beat until very smooth. Continue adding the rest of the flour and beating until the dough leaves the sides of the bowl and isn't sticky to touch. Remove dough, and place in a large greased bowl. Cover with a dish cloth and allow to rise for about 45 minutes.
After dough has risen, pound down and place on a floured surface. Roll dough out in to a large rectangle. This makes a HUGE rectangle - you may want to divide dough in half and do it in two batches.
Melt 1 1/2 cubes of butter and spread melted butter over the dough. Sprinkle granulated sugar, brown sugar, and cinnamon all over the top (probably about 1 1/2 cups of each kind of sugar and 2-3 T. cinnamon). Roll up and cut in to slices (I use a piece of thread to cut the slices). Place rolls on greased cookie sheets and rise another 30 minutes to an hour.
Bake at 350 degrees for about 15-20 minutes or until well browned. Then frost with homemade vanilla butter cream frosting.
Make homemade frosting by combining 1 cup softened butter, 2-3 T. milk and about 3 cups powdered sugar. Thin by adding more milk, thicken by adding more powdered sugar.
