Preheat oven to 180°C. Line and grease an 8X4 inch loaf pan.
In a large mixing bowl combine flour, cocoa powder, baking soda, baking powder, salt, all spice powder and cinnamon. In another large bowl beat together oil, apple sauce, jaggery powder, curd and vanilla extract. Fold in the grated zucchini and squash in the wet ingredients bowl.
Now add dry ingredients and mix gently till combined. Fold in chocolate chips, tutti-fruiti and dried cherries. Pour the batter in prepared pan and bake for 60-65 minutes or until the toothpick inserted comes out clean. Transfer the pan to a wire rack and allow it to cool completely. Slice it and enjoy when cold.
I substituted based on what was available in my pantry. You can follow as per your preference or from the original recipe.
