Green grass decoration for a chocolate fudge 'digger' cake!

[Cantturnleft]

Hi,

Just wondering if anyone could help with this! I'm sure there is a straightforward solution but for some reason my head is a bit muddled and I'm stuck. As the title suggests, I'm making a chocolate fudge 'digger' cake for my DS's 2nd birthday. I can't attach a photo for some reason but it will be a round cake with diggers driving on a large two outline on the cake (sorry for the complicated description!) I know I could pipe some green buttercream icing to look like grass but wasn't sure if it would taste ok with the chocolate fudge. The 'road' will be either chocolate or fudge icing. I know it seems like a small thing to worry about but he's had an awful year and would love this to be right. Really appreciate any advice, thanks!

Dessicated coconut dyed with green food colouring - it was all the rage on birthday cakes when I was about 5 in the dark ages

What about colouring desiccated coconut green and sprinkling that? Tbh I think butter icing would taste fine...

What Seeline said! My Mum had a novelty cake cookbook in the 80's, lots of coloured coconut!

If you're worried about the taste what about melting some white chocolate, then colouring it green, then grating it on when set? I appreciate this is fiddly.

Or - get some green fondant icing, put it in the freezer, then grate that?

Wow, thanks for the swift replies! I have a huge bag of dessicated coconut and a block of green fondant icing so will experiment and report back! Thanks so so much!
