Step 1

Preheat the oven to 180C (350F).

Step 2

Cream the butter and sugar on an electric mixer on medium-high speed until light and fluffy. Add the eggs, one at a time making sure to scrape the sides and bottom of the bowl.

Step 3

Gradually add in the flour and spices and continue mixing until fully incorporated.

Step 4

Scoop the batter ¾ of the way up into 2 x semi-sphere silicon moulds and bake for 15-20 minutes or until a toothpick inserted in the middle comes out clean. Leave to cool.

Step 5

Make the fondant tentacles by marbling the purple fondant with a bit of white like shown in the video. Mould the tentacles individually and add the suckers. Let them dry.

Step 6

To make the eyes, form small balls out of white icing and let dry before painting. Once set, paint a small dot with the cake craft pen and add shadow with the black lustre dust.

Step 7

To make the buttercream, mix in the vanilla into the icing and then add colour gradually until you achieve the desired shade. Fill a piping bag and set aside.

Step 8

Stick the cake semi-spheres together with a little buttercream. Cover the now fully round cakes with black fondant and smooth out. Roll out a sausage shape out of fondant and attach to the sphere. This will be the rim of the cauldron.

Step 9

Pipe the buttercream on top and add the tentacles and eyes.

Step 10

Repeat the process with the rest of the cakes.
