Butternut squash, chocolate and orange cake

Butternut squash... really?  I have done beetroot chocolate cake before, but not butternut squash.  It's pretty good, but not too sweet.  The recipe has a ganache topping, but I didn't have any cream, so served it with cherry ice cream - will get some cream or something for tomorrow.  It would be good with orange cream cheese frosting, but I think that defeats the lower fat/ lower sugar - but still cake point of it all.  Recipe more or less from here http://www.bakingmad.com/recipes/cakes/butternut-squash-and-chocolate-cake but I added zest of an orange, which I think went well.
