Castle Cake Decorating Set
A proper fairytale castle cake, towers and all, and not a scrap of fondant in sight. Two cylinder towers, one cube keep and a handful of lollies become the kind of castle that gets photographed before it gets cut.
The Castle Cake Decorating Set has a sheet of edible designs (a door, windows, a prince and princess, and flowers) plus paper cone roofs and turrets. The turrets are the bit everyone comments on. They take about two minutes.
Please note: cake mix, icing and lollies are not included.

Castle Cake recipe and step-by-step guide
The Shape Book guide walks you through the whole build with photos.
Bake
Bake two cylinders and one cube. If you only have one Cylinder tin, bake, cool, wash and go again.
Build
The cube becomes the castle, the cylinders become towers either side. The guide shows where everything sits.
Decorate
Ice, add the door and windows, pop on the prince and princess, then crown each tower with its roof and line the castle with turrets.
Decorating your Castle Cake
Choose your kingdom
Pink and lilac for a princess castle, grey and blue for knights, or white for a snow palace.
The castle garden
Mint leaves tuck in around the flowers, a piece of plain chocolate makes the drawbridge, and jubes with TV Snacks make a railing along it.
Party-day plan
Bake the night before. Fold the cones and turrets ahead of time so the morning is just icing and placing.
This one's up to you. Colour your buttercream however you like.
