This tutorial was uploaded as part of the Renshaw ‘Battle of the Bakes’ competition.

My little boy’s 4th birthday cake. He wanted a castle, a knight and a dragon and that’s what he got. It was super simple using the hints and tips.

Decorating ingredients

  • 2 kg Renshaw White Ready to Roll Icing
  • 500 g White chocolate
  • 500 g Renshaw Modelling Paste
  • 500 g Rice Krispies


Step 1

To create the towers either side of the 2-tier cake, I figured it would be difficult to do this with cake so I came up with the idea of taking a Pringles tube and lining it with grease proof paper.

Step 2

I then melted the white chocolate and added the Rice Krispies, mixing them together. I pushed the Rice Krispie mixture into the Pringles tube and put it into the fridge to set.

Step 3

Once it was hard I covered it in buttercream and covered it with Renshaw Ready to Roll Icing that had been coloured grey. I used a brick pattern to press into the icing.

Step 4

To create the battlements along the top of the towers and the tiers of the cakes I used the renshaw modelling paste and it is stiffer and dries quicker so holds its shape better for standing up without support. I rolled out the modelling paste which had been coloured a darker grey and cut strips about 2cm wide (the length depending on how long you would need to go around your tower etc) I then used a square cutter to cut out sections making sure not to cut to far down the strip only about 1 cm.
