Colour all the fondant you are going to need. Dip a toothpick in the gel colour, rub it onto the piece of fondant you want to colour, and knead until the colour is uniformly combined.

Prepare the fondant decorations about 3 or 4 days before the party. Keep the fondant wrapped and stored in a dry place so it doesn’t harden.

To make Tinkerbell and Blaze, create custom stencils. Print the image you want to make, place transfer paper between the image and clean cardboard, and trace the outline with a pen before cutting out all the single pieces with a sharp exacto knife or craft knife. This method is reliable, works well for detailed fondant pieces and cookies, and allows almost any design to be recreated.

The day before the party, assemble the cake. Make icing for the crumb coating using your favourite recipe, keeping it slightly less dense so it spreads easily. Take the 2 yoghurt cakes out of the freezer and level them while still frozen with a sharp serrated knife.

Spread a layer of icing on one cake and top it with the other cake. Choose the smoothest and flattest surface for the top (this is usually the bottom of one of the cakes), as this makes icing and decorating easier.

Crumb coat the cake while it is still frozen, as this is much easier when the cake is firm. Start from the top, then coat the sides. Use a cake spatula to smooth the surface as evenly as possible. When the cake is fully coated, place it in the fridge to harden. This coating will make the fondant top look smooth and will prevent crumbs from showing through.

When the icing has set, transfer the cake onto a cake board and secure it to the base with a little icing.

Roll out the lavender fondant and cover the top of the cake with it (no need to go all the way to the bottom as this part will be covered with the green fondant, so trim off the excess lavender fondant with a sharp knife). Roll out the green fondant and cover the remaining cake and the base with it. Smooth it with a fondant smoother and cut out any excess.

Cut strips of green fondant to resemble long grass and “glue” them around the cake using a little water.

Using water, attach all the decorations that were prepared earlier, including Tinkerbell, Blaze, colourful flowers, two toadstools, a small bee, and a ladybird.

Just before serving, sprinkle some golden-coloured sugar onto Tinkerbell’s wings to create a “Pixie Dust” effect.
