1Combine flour, cocoa powder, baking soda, and baking powder in a bowl.
2Mix the yogurt and vinegar in a large bowl. Let stand for 5 minutes to sour the yogurt. Beat in the butter, sugar, vegetable oil, eggs, and vanilla extract.
3Stir the liquid ingredients into the flour mixture until just combined. Fold in the zucchini and dry cherries.
4Pour batter into the prepared pan, and sprinkle with chocolate chips.
5Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 45 minutes. Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
We leave in the pans and eat with out frosting but a cream cheese frosting or whip cream would be good toppings... This cake reheats well..
