• Step 2 Use an electric mixer to beat butter and caster sugar in a bowl until pale and creamy. Add eggs, 1 at a time, beating well after each addition. Add sour cream. Beat to combine. Add combined flour, coconut, orange rind and orange juice, in alternating batches. Tint orange using red and yellow food colouring.

• Step 5 butter in a bowl until very pale and creamy. Gradually add icing sugar, beating well after each addition. Add milk. Beat to combine. Add chocolate. Beat to combine. Tint orange using red and yellow food colouring.
• Step 6 Use a serrated knife to trim the top of each cake. Halve cakes horizontally. Spread cut sides with a little orange icing and sandwich together. Place 20cm cake on a serving plate. Spread top and sides with orange icing. Use a serrated knife to cut the top of the 15cm cake on an angle. Place on the 20cm cake. Spread top and sides with orange icing.

Decorate with plastic spiders, if desired.
