In a large bowl, mix the yeast and water together. Add sugar, margarine, and egg and mix well. Add flour and knead for two to three minutes, until a nice dough forms. Do not over-knead or the dough will get tough.

Sprinkle flour on the counter. Roll the dough out into a large rectangle.

Drizzle filling ingredients over the dough. Roll up jelly-roll style.

Cut into one-and-a-half-inch pieces and place in a 9×13-inch pan.

Cover with a towel and let rise for 30 minutes.

Meanwhile, preheat oven to 350 degrees Fahrenheit.

Bake for 15–20 minutes, depending on how gooey you like your cinnamon buns.

In a bowl, combine icing ingredients. Drizzle over the warm cinnamon buns.
