I had seen something similar to this a while ago and last night I had a great opportunity to try it out. It was simple and fun to make.
1 9 x13 cake no frosting
Fruit by the foot 1 box of 6
toppings for "sushi"
chocolate wafer cookies
I used a white cake so it would look like rice then when cool I cut out pieces with a round biscuit cutter. I put them on the chocolate wafer cookies for more support. Next I wrapped each piece with fruit by the foot and then topped them with Swedish fish. Great for a kids party.
