Who Wants Cinnamon Rolls?

This recipe was found in the Friend Magazine in, I think the 1950's. My neighbor shared it with us for a Young Women's activity. It's super easy, yummy, and fast. Those are the descriptions I like before making something. :) It only takes 15 minutes to let them rise and 15 minutes to cook them. Here's the recipe.
Quick Cinnamon Rolls
1/2    C. Sugar
4 1/2 T. Yeast
3/4    C. Butter
2       C. Hot Water
Mix in mixer and let set for 15 minutes.

Then Add
3  eggs
2 1/2 t. salt
7 1/4 C. flour
Mix in mixer.
Roll out onto floured surface 1/2" thick. Spread 1/2 C. melted butter over dough. Sprinkle with brown sugar and cinnamon ( I don't have measurements for this, but the more you use the tastier it is. Probably like a cup of brown sugar and 1/4 C. of cinnamon?) Roll up dough to create a long tube. Use a long piece of thread to cut into 1" thick slices.  Place on cookie sheet. Bake 425 for 10-15 minutes. It made 25 when we did it.
Frost: 3 C. powdered sugar, 2-6 T. butter, 3/8 C. hot water.
