A Tom and Jerry cake is an ideal cake for a child who loves the show Tom and Jerry. A Tom and Jerry cake is not hard to make, but it does take quite a long time to form all of the characters that go on the cake. The image of Jerry hitting Tom with a mallet is one of the hallmarks of the show and will help people identify the cake as a Tom and Jerry cake even if your sculptures look a little different from the show's characters.
Mix the cake batter according to package directions. Cook half the batter in the large bowl. Cook the other half in the cylinder container. Bake according to package directions. Allow to cool to room temperature.
Turn the bowl flat side down onto the middle of the cake board. This cake will become tom's head. Surround the cake bowl with a circle of black fondant to make it look like the rest of Tom is inside a hole. Cover the cake with buttercream frosting.
Roll out some grey fondant. Cover the bowl cake and trim the excess. Mold two oval shapes from white fondant to make Tom's mouth and muzzle. Make six small ovals from white fondant for tom's paws. Place the paws coming out from the black hole. Poke three or four holes into each side of the muzzle with a toothpick for whiskers.
Mold two triangles from grey fondant for ears. Place a smaller triangle of white fondant inside the larger triangles. Stick the ears around the head with toothpicks. Make two flat 1/8-inch thick ovals from white fondant for Tom's eyes. Place two yellow circles inside the middle of the eye with a black circle for a pupil. Give Tom two black or grey eyebrows.
Cut the Swiss roll to about 6 inches long. Cover the roll in buttercream icing. Cover the roll with white fondant. Draw some lines on the fondant to look like wood grain. Place the mallet on top of Tom's head using a dowel rod. Form a handle for the mallet from white fondant and stick it to the mallet with a toothpick. Mix orange and brown food colouring and paint the mallet so it looks like wood.
Make two large balls from brown fondant to make Jerry's body and head. Stick the balls on top of the mallet. Make two ears from brown fondant and stick to the head with toothpicks. Form four legs from brown fondant and stick next to the body. Make a long brown tail for Jerry to hang down the mallet. Form a small muzzle from brown fondant and stick it to the front of the head. Give Jerry a small black nose. Roll some white fondant into two small ovals 1/8-inch thick. Stick these to Jerry's face for eyes. Glue two small flat black circles to the face for pupils. Give Jerry small black eyebrows.
Cut out several stars from 1/8-inch thick yellow fondant. Stick them randomly around the cake to make it look like Tom was just hit in the head by the mallet.
