Coconut Bread for Mele

This is one of the fabulous recipes that Nikki brought home from her mission! It makes two loaves.

Beat 4 eggs
Add 2 c. sugar
1 c. oil
2 tsp coconut extract

Sift 3 c. flour
1/2 tsp baking soda
1/2 tsp baking powder
1/2 tsp salt
then add 1/2 c. coconut

To the egg-oil mixture, alternate adding the flour mixture and 1 c. buttermilk. Example: buttermilk, flour mixture, buttermilk, flour mixture
You can add 1 c. chopped pecans or nuts to the batter now if desired. Bake at 325 in greased loaf pan for 1 hour.

Glaze:

1 c. sugar
1/2 c. water
2 TBLSP butter

In a saucepan sprayed with non stick spray, add all ingredients. Let boil without stirring for 5 min. Remove from heat, add 1 tsp coconut extract. Drizzle over warm bread. Every once in a while the glaze turns rock hard and I don't know why. Any ideas?
