My sons opted to have a joint birthday celebration with a Western Bull Riding theme. They even had mechanical bulls to ride at the party.

I created this cake after searching the internet for inspiration.  They each had their own individual round cake, topped with fondant accessories. Jake had a cowboy hat, and Josh a cowboy boot.

I designed with center to look like a belt buckle, with their age as the center of the buckle.  All created from fondant.

The sheet cake was with icing, with a picture of a bull that was cut from fondant.

To complete the western theme of the party, I displayed the cakes on burlap covered cake stands.

The cake was a huge success, and very yummy!  If you have never used fondant before, I would recommend practicing with play dough some before cake time.  It will take the stress out of cake process before party.

Good luck!
