MC's birthday was last Tuesday. He's such a great kid--not without flaws, but terrific nonetheless. I love him. No matter what.
I tell him he needs a hobby, and he tells me his hobby is playing Xbox. What I really meant was that he needs a non-electronic hobby that he can do either by himself or with others, but it is true--Xbox is his hobby. So when MC couldn't decide what kind of cake he wanted, I figured something Xboxy would be appropriate.
One of the things he asked for for his birthday was an Xbox controller. So I gave him one.
To get the smooth, plastic-ish look, most people would use fondant, but I heated store-bought chocolate frosting in the microwave, 20-30 seconds at a time, until it was pourable. I added black food coloring and stirred until the color was uniform. Then I carefully poured the frosting over the cake. I was not very careful while I was cutting, so the sides were a bit rough, and I also wasn't very concerned with how the sides looked, so I didn't do much smoothing after I poured the frosting. If you are looking for smooth sides, I would recommend icing with a crumb coat first, before pouring, then smooth as you pour/after you pour.
I think he liked it.
