Split and
fill the sponge cake with butter icing. Cut a
10cm/4in wide piece diagonally across the
middle of the cake, about 25cm/10in long. Shape
the nose end and straighten the other end.
From the off-cuts
make three 7.5cm/3in triangles for the wings and top
of the ship. Cut two smaller triangles for the
booster jets. Position the main body, wings and top
of the cake diagonally across the board. Add extra
pieces of cake in front of the top triangle. Brush
the cake and booster jets with apricot jam, then
cover with a layer of marzipan and sugar-paste icing.
Divide the
remaining sugar-paste icing into three. Tint blue,
pink and black. Roll out the blue icing and cut it
into 1cm strips. Stick around the base of the
cake with water and outline the boosters. Cut a
2.5cm strip and stick down the centre of the
spaceship.
Roll out the pink
and black sugar-paste icing separately and cut
shapes, numbers and the child's name to finish the
design. When complete, position the boosters.
Make small cubes
with the off-cuts of sugar-paste icing and use to
stick the candles to the cake board. Decorate the
board with gold stars.
