Chocolate Zucchini Bread

This is a pretty good spin on the original.  I got the recipe from my mother-in-law's cookbook.

Ingredients:

1/2 cup margarine or butter, softened
1/3 cup shortening
1 3/4 cups sugar
3 eggs
1/2 cup sour milk or buttermilk (you can add a little vinegar to the milk to get sour milk)
2 cups unpeeled, grated zucchini
1/2 tsp baking powder
1/2 tsp salt
1 tsp baking soda
4 T cocoa powder
2 1/2 cups flour
1/2 tsp cinnamon
1/4 tsp cloves
1 tsp vanilla
Topping:  1/4 cup chocolate chips & 2 T sugar

Preheat oven to 325 degrees.  Beat margarine, shortening and sugar until combined.  Add eggs, one at a time beating well after each addition.

Alternately add milk, zucchini and dry ingredients (and vanilla).  Mix until just blended.

Pour into two greased loaf pans and sprinkle with sugar and chocolate chips.

Depending on pan used, bake 40-60 minutes or until inserted toothpick comes out clean (I baked them for 50 minutes in 2 regular loaf pans).
