Chocolate Zucchini Spice Cake

I must admit, I was always sceptical of chocolate zucchini cake growing up and was hesitant to try it.  Maybe it was because my family didn't grow vegetables growing up so I never tried zucchini as part of anything.  When a friend of mine told me she was going to use chocolate zucchini cake for here wedding cake I was shocked and thought she was a little crazy.  Then came her wedding day and I was pleasantly surprised when I tried the cake.  Since then I have tried to open my mind to experimenting more and I am glad I did.
For the past few years I have been using the same recipe for chocolate zucchini cake but the other day I decided to try a new one with a bit of spice to it.  I really enjoyed the end product and those who helped me eat it did as well.  This is another recipe that works well for using up a large zucchini.
