I made this robot birthday cake for my sons fourth birthday, per his request.  It was so much fun to make, and it wasn’t too difficult either!  I chose not to cover the cake in fondant (except the neck) because I don’t love the way any fondant tastes. I opted to just cover the cake in buttercream.

Robot Birthday Cake Instructions

  • The base of the robot (robot’s body) is made from four 8 x 8 square cakes.
  • The head of the robot is made from two 6 X 6 square cakes.
  • The neck is made from a 6” round cake, which I trimmed and made even smaller, so it was probably closer to 4”.
  • The arms and legs are mini donuts.  To get the silver color, I used Wilton icing spray that can be found at most craft stores, or even Wal-Mart.
  • All of the décor (eyes, mouth, control panel) are made of fondant.  I did all of this detail work ahead of time, to make the construction process smoother and less time consuming on the actual day of the birthday.
  • The antennae are actually silver candles with small balls of fondant at the tips.
  • The ears are mini Reese’s Peanut Butter Cups.
  • Make sure to use dowels for the necessary support (especially if you want to do a neck, although I think the cake would look ok without a neck) when stacking them.

I loved seeing the reaction from my four year old when he came in from playing and saw the final piece.  Truly priceless!  This was definitely a special cake for a special little boy!
