Grease and flour a 8 x 8 inch baking dish (I used coconut oil, and whole wheat pasty flour).
Whisk together all dry ingredients in a large mixing bowl.
Add water, oil, vinegar, and vanilla.
Mix with a whisk or spatula until combined.
Add zucchini and 1/4 cup carob chips, stir.
Pour into prepared baking dish and sprinkle with remaining carob chips.
Bake for 35 minutes or until tooth pick inserted comes out clean.
Place on a wire rack to cool.
