Chocolate Zucchini Cake

I am constantly trying to find ways to use my abundance of zucchini (or yellow squash this year) this is one sweet way to use them.

1/2 C. Butter
1/2 C. Oil
1 3/4 C. Sugar
2 Eggs
1 tsp. Vanilla
1/2 C. Sour Milk or Buttermilk (I used sour cream and added some milk to make it thinner)
2 1/2 C. Flour
1/2 C. Cocoa
1 tsp. Baking Soda
1/2 tsp. Baking Powder
1/2 tsp. Salt
1/2 tsp. Cinnamon
2 C. Shredded Zucchini
1 1/2 C. Chocolate Chips
1/2 - 1 C. Chopped Walnuts (optional)

In a mixer, cream Butter, oil and sugar. Beat in the eggs, vanilla and sour milk. Then add the Zucchini and dry ingredients along with 1/2 C. chocolate chips. Pour batter into a greased 9X13 pan. Sprinkle chopped walnuts and remaining 1 C. of chocolate chips on top of the cake. Bake at 325 for 40-45 minutes.

Personally I prefer it without the chocolate chips and without any glaze, but you could easily make a glaze out of powdered sugar, milk and vanilla. It really just tastes the best with vanilla ice cream, that's not just my opinion that is a fact :)
