Dutch Schnecken

Dutch Schnecken

1 cake Yeast dissolved in: 1 c Water, warm
5 tb Sugar
1/2 ts Salt
2 c Milk, warm
2 ea Egg, well beaten
1/2 c Butter, melted
1 x Flour

Topping:
4 tb Sugar
4 tb Butter
1 1/2 ts Cinnamon

Dissolve the yeast cake and add one Tbsp of the sugar and the salt and enough flour to stiffen to a sponge. Let rise for one hour, then add the rest of the ingredients, using enough sifted flour to make a soft sponge. Let rise again, then roll out dough on a floured board and cover with a mixture of 4 Tbsp sugar, 4 Tbsp butter and 1 1/2 tsp cinnamon. Roll like a jelly roll and cut in 2 inch pieces. Place on well-greased pans and let rise for a third time, then bake at 400-F for 20 minutes.

1 cup yeast? Is that correct?

What is the equivalent of dry yeast to 1 cake?

Thank you.
