I was asked to make an Ice Age themed cake for someone, which was to include the Scrat character. At first I thought this was going to be really difficult and a daunting challenge. Then I had a brainwave. What if the cake was the ice cracked in half and the Scrat character was in the middle- like the Ice Age 2 poster.
I made the Scrat character whilst the cake was baking in the oven. The next night I torted the cake into 3 sections each filled with pale blue buttercream icing. Then I cut the cake in half down the middle and shaped the zig-zag edges. When it came to icing the cake, the zig zag edges became a problem. The icing wasn't easy to smooth into all the cracks and the cake was crumling. However, when I had done the second side of the cake I realised that the creases added to the ice effect (plus they are on the inside of the cake so you don't really see them). I brushed the cake with lustre dust to give it an icy shimmer and then painted the cracks on in pale blue icing colour.
This is a close up of the Scrat character which is wedged inbetween the two pieces of cake.
