The birthday boy requested an Oreo soccer cake and this is what I came up with.
It's not much of a tutorial because it's so easy :)
The Oreos are all anchored with buttercream.
I didn't mind if the buttercream was sloppy for this one because it was a soccer field and I was going to have grass coming out of all the seems anyways. If you wanted a cleaner edge presentation, don't use as much buttercream. Simply a dab on the bottom of each will hold it in place.
Spread the top with a layer of buttercream. I wanted to be able to see the Oreo layer so I didn't go all the way to the edge.
I added the soccer field lines as well as "grass" to the sides using the Wilton grass tip.
The players were purchased from a cake supply store.
The Oreos were slightly softened by the buttercream so we could cut into it like a slice of cake. The presentation made for a very pretty slice of cake!
