I created this cake for my Lego-maniac son's birthday. It is a bostom cream cake covered with rolled fondant. I rolled fondant thicker and used a small cookie cutter for the knobs on the top of the cake for the lego brick look. My son's name is rolled fondant and I used one of my decorating tips to make the knobs. The lego block pieces are made of rolled fondant as well. As far as the Star Wars figures and ships, they are real lego pieces. My intent was to sculpt them from fondant, ran out of time.
