Knead in dry ingredients. Add butter. Let rise for 45 minutes.
After the 45-minute rise, roll out dough into a long rectangle and spread butter over its surface. Sprinkle it with a generous amount of light brown sugar, cinnamon, and salt.
Roll up the rectangle into a long cylinder. Cut into fourteen, 2-inch pieces. Place in a greased 9-by-13-inch pan or two 10-inch pie pans and cover with plastic. Let rise another 45 minutes before baking 12-22 minutes at 375°.
To prepare the frosting, mix butter, cream cheese, extract, sugar, and salt thoroughly.
While the buns are still warm, spread the frosting generously over them and serve immediately. Watch as they disappear before your very eyes.
