Chocolate Zucchini Cake with Struesel Topping

Preheat oven to 325 degrees F. Grease and flour a 9 X 13 baking dish.

Cream butter, oil and sugar together in a large mixing bowl. Blend in eggs and vanilla extract. Set aside.

Sift dry ingredients (flour, cocoa powder, salt and the baking soda and powder) together in a medium sized mixing bowl.

Into the creamed mixture, add the flour mixture and buttermilk alternately in thirds. Stir in the zucchini. Spread the batter into the prepared baking dish.

In a small mixing bowl combine the chocolate chips, brown sugar and the chopped walnuts to make the struesel topping. Sprinkle over the top of the cake mixture.

Bake for 40-45 minutes or until toothpick inserted in center comes out clean.

Serve with vanilla bean ice cream!
