Chocolate Zucchini Muffins

Ok, I know it may not sound healthy with the word chocolate in it--but it doesn't hurt to add a little chocolate with our vegetables, right?
It's really good.

2 1/2 cups all purpose flour
1/4 cup unsweetened cocoa powder
1 T. salt
1/2 tsp. baking powder
1 tsp. baking soda
1/4 cup ground flaxseed
1/2 cup margarine
1/4 canola oil
1 1/2 cups granulated sugar
2 eggs
1/2 cup sour 1% milk
2 cups finely grated, unpeeled zucchini

Preheat oven to 350 degrees. In a bowl, combine flour, cocoa, salt, baking powder, baking soda and ground flax. In a separate bowl, cream margarine, oil, and sugar. Add eggs and sour milk. Add flour mixture, stirring until just mixed. Add zucchini and mix. Fill paper baking cups half to two thirds full. Bake 18-20 minutes or until wooden pick inserted in center comes out clean. Remove and cool. Yield: 24 muffins. (Can also make as a cake--bake a little longer)
