Put cake on a stand or serving plate and spread top and sides with the jam. Unroll marzipan, position on top of cake and press down gently over top and sides. Lightly dust the worktop with icing sugar and roll out the blue icing into a 33cm (13in) circle.
Step 2
Brush the top and sides of the cake with water. Position blue icing on top of the marzipan. Using the palms of your hands, flatten icing over top of cake and ease around the sides, smoothing any creases. Trim off excess with a knife and tie the ribbon around the base.
Step 3
Re-dust worktop with icing sugar and roll out white icing. Stamp out snowflakes of various sizes and stick to the cake using a little water (re-roll icing as necessary). Wet the centre of each flake and stick on a silver ball.
Step 4
Lightly brush the cake with water and sprinkle over edible glitter (water helps the glitter to stick). Use a dry pastry brush to even out the glitter if necessary. Store in a cool place.
Dye it yourself
Dye your own ready-to-roll icing by whizzing it in a food processor with a little food colouring paste (available from cake shops) - avoid liquid colourings as these will make the icing too wet. Knead icing until smooth and use as above.
