Pittsburgh Penguins Cake

Hockey is back in Pittsburgh!

And what's better for a hockey fan's birthday than the team's logo on a traditional yellow cake with chocolate icing?

I decided to use the royal icing transfer method to make the decorations on the cake.  The advantage is that the design can be made ahead of time so you don't have to worry about decorating at the last minute.

It's just like decorating a cookie with royal icing, except you are piping directly onto waxed paper instead of onto a cookie.  The design can be printed out on paper and placed under the waxed paper so you know exactly where to pipe.

Outlines of the design need to be piped with stiff-consistency icing, allowed to dry, and then the spaces are "flooded" with 10-second icing.   10-second icing is stiff icing to which water has been added a few drops at a time until a spoon can be drawn through the icing and the icing becomes completely smooth in 10 seconds.  A good video for learning how to get the right consistency for flooding can be found here.
