I was little nervous as I was reading peoples review while I was making the frosting. I started making it in a blender, but them moved it to my miser before adding the chocolate (looking back it would have been fine in the blender). It turned out perfect!! It's not grainy. I plan to use this frosting revise next time I make brownies. Entire recipe, 5 stars!!!

Very moist recipe. I added 1/2 cup chocolate chips to the batter. Baked in a springform pan and added extra bake time. 20-25 minutes. I did not use the frosting recipe. This would also make excellent cupcakes! VFE.

Loved this cake, especially since it may have fewer calories than most chocolate cakes. I was skeptical about only a cup of oil, but it had plenty of moisture from the zucchini. I'll probably make it for Christmas since I'm in the mood for a dessert that's not so rich and overly sweet.

Cake 5 stars - Frosting 1 Star...so overall I gave this a 3 Star. I kept reading over and over again on the 1 cup of sugar in the frosting (wanted to use powdered sugar-but the recipe called for sugar). Going only 45 seconds - it was smooth..my fault I did not taste it then or maybe I could have saved it from being grainy - I added the melted ing. and then ran it about 1 minute and was very disapointed on the grainy frosting. I wished I would have came in and read the reviews before I baked this - would have saved me some frustration.

This recipe is BY FAR the most delicious chocolate cake of any kind that I have ever eaten!! I accidentally shredded closer to 3 cups zucchini so I added the additional and it turned out amazing. It was gone in a day and a half...need I say more.

This is an awesome cake. Very rich and moist. I used almond extract in both the cake and the frosting as well as substituting buttermilk for the yogurt. I made the frosting using my food processor and it was amazing!! I will definitely make this cake again!!!

Wonderful cake -- the cinnamon makes it special.

Liked this very much, especially the frosting, which I used on another cake. Did not find it grainy at all. I suggest making the frosting in the mixer, not in the blender. I tried both ways and while the mixer took just a little longer, it was much easier to clean and no frosting went to waste between the blender blades.

This cake is awesome.. the trick to not having grainy icing is to mix the milk, sugar & vanilla for a good amount of time.. just let your mixer run (aside from stopping it to scrape down the sides) until the milk & sugar have thickened a little & sugar is no longer grainy.. then mix in the melted chocolate & butter. I squeezed as much moisture out of the zucchini as I could & chopped it (after grating it) to make it really small. The other thing I did to make it more nutritious was use a better oil, I used English walnut oil, but I like sweet almond & safflower oil too. The only thing I didn't like was the total of 3 cups of sugar in the recipe.. so I might try using a little less sugar in the cake next time.. otherwise I think it was a very easy cake recipe & it will be a regular thing with my family! Love it!!
