1) Prepare cake

To prepare your cake rounds for the fondant, ice them with a layer of buttercream icing.

2) Cover cake with fondant

Knead green fondant until soft, and then roll out and cover the cake. Trim off the excess with a pizza cutter or paring knife.

3) Create bandana

Time to give your cake some TMNT personality! We chose the sharp ninja eyes and orange bandana of Michelangelo, but you can easily pick another Turtle brother. Draw out the bandana on a piece of paper, making sure it's long enough to wrap around the cake.

4) Attach bandana

Color white fondant orange, knead until evenly distributed and roll out the orange fondant. Lay your bandana drawing on top and cut out the fondant with a paring knife or pizza cutter. Use water to "glue" the bandana to the cake.

5) Create eyes

For the eyes, first color a small amount of white fondant black and another small amount sky blue. Knead and roll out a little bit of white, black and blue fondant. Cut semicircles from the white fondant and circles in two different sizes from the blue and black fondant. Trim slight edges off the circles, making them all even, for the pupils and irises. "Glue" on the eyes with water. Tip: The backs of piping tips in two sizes work perfectly for cutting out circles!

6) Make nunchuk chain

Now give Mikey his nunchucks! To make the chain, roll some white fondant between your hands with a rubbing motion to form a rope, cut three lengths and join them with dabs of water. Spray with Silver Color Mist and let dry.

7) Finish nunchuks

For the handles, dot some white fondant with brown icing color and knead until mixed. Mold into handles with your hands and lightly score them with a knife or toothpick for a realistic appearance.

8) Attach Sixlets

Decorate the cake with kiwi green Sixlets® at the base!

9) Top with candles

Top off your masterpiece with Teenage Mutant Ninja Turtles candles. Master Splinter would be proud!
