To make three loaves of povitica, mix 1 1?2 cups of lukewarm milk, 2 teaspoons of salt, 1/2 cup of sugar, 2 beaten eggs and 1?4 cup of soft butter. Dissolve 2 packages of Fleischmann active dry yeast into 1/2 cup of warm water, and add this to the mixture. Add 4 cups of flour, and mix the ingredients until smooth. Add more flour for easy handling.
Cover the dough in a greased bowl, and let it double in size in a warm, draft-free place. Punch down the dough, and let it double again. Divide the dough into three parts, and roll them into thin rectangular shapes. Spread the filling, roll it, and twist it in a circular shape like a cinnamon roll. Let it rise in a warm place inside 8- or 9-inch greased cake pans. Bake the dough for 40 minutes at 350 degrees Fahrenheit.
For the filling, mix 1 1?2 cups of sugar, 1 can of evaporated milk and 1 cup of margarine over medium heat in a heavy pan. Add 1 1?2 pounds of fine ground pecans or walnuts and 4 beaten eggs. Boil for one minute while stirring constantly. Remove the filling from the heat, and add a mix of 1 teaspoon of cocoa and 1 teaspoon of cinnamon with a pinch of salt. Let it cool, and spread while still warm.
