Step 1

To cover all three cakes you will need approx. 3.5 Kg paste, depending on the depth of your cakes.

Cover 10” base cake with brilliant white icing, taking it out to the board edge. Neaten around the base. Using the flexi smoothers, create a sharp top edge on the cake. Allow to dry.

Repeat this process with the 8” cake sitting on an 8” cake board, neatening around the base, and creating a sharp top edge. Repeat again with 6” cake. 

Dowel the 10” and 8” cakes, cutting the dowel rods off flush with the top of the cake. Assemble the cakes.

Step 2

Take the white modelling paste, the gold and purple sugarpastes, and use these to create various marbled patterns. You may, if you wish, use some plain colours as well. (The modelling paste adds some strength to the marbled shapes when cut)


Step 1-  Choose the proportions of paste colours. You may wish to have predominantly white, purple or gold, or equal amounts. Knead well and roll into balls.

Step 2- Roll into ‘sausages’.

Step 3- Join ‘sausages’ together and roll.

Step 4- Fold and roll again.

Step 5- Fold, twist and roll.


Roll out and cut hexagon shapes in three sizes. Add shapes (with glue) to sides of cakes in a random design, cutting some infill shapes around the base.
