Lover of all things mechanical and sugary? Prefer interaction with machines to interaction with people? Funfetti fan? This is the cake for you.
Step 1: Bake a Cake
Bake your delicious cake of choice (hint: choose Funfetti) in a 13x9" pan, according to the directions on the box. If you want to be fancy, bake it from scratch. Let it cool completely, and flip it out onto a sheet.
Apologies for the abysmal lighting. This all happened late at night in a sleepwalking induced cake-a-thon. Just kidding--I have a terrible flash so I tried not to use it.
Step 2: Slice/Dice
Cut off a chunk of cake about 4-5" from one end. Separate the chunk, bisect it, and arrange the two pieces side by side to form a roboty-looking head with a rounded edge.
Now use a large knife to cut off the rounded top of the cake and make it nice and flat.
Step 3: Frost
Grab some food coloring and make a few bowls of different colored frosting. Just mix 2 or 3 drops of food coloring in with your vanilla or cream cheese frosting. We used a whole tub for blue frosting (the base color), and split the other tub between pink and green for decoration.
Use a frosting knife or spatula and apply the base color to the top and sides of the robot.
Step 4: Decorate
Put your accent color frosting in ziploc bags, close them, and snip a tiny piece off the corner to make a homemade piping bag. Go to town on the cake--we made some circuit boards, random buttons, piping, a robot face, etc. A single candle acts as an antenna in the head. We named our robot according to the initials and age of the birthday boy -- the MD25. As you can see, he was pleased.
