Decorating ingredients

  • 3 kg Renshaw White Ready to Roll Icing
  • 250 g Renshaw Jet Black Ready to Roll Icing
  • 1 tsp blue gel food colour
  • 1 tsp brown gel food colour
  • 1 tsp black gel food colour
  • 1 tsp paprika gel food colour


Covering the cakes:

Step 1

Bake two sponge cakes, one an oblong shape and the other square.

Step 2

Once cakes have been baked and cooled, crumb coat using butter cream made from butter and icing sugar.

Step 3

Knead some of your white icing with brown gel colour to get the shade needed for the table top, then roll out the icing and put on the oblong cake. Set to one side.

Step 4

Trim the corners of your square cake so that it is shaped more like a computer monitor.

Step 5

Knead more of your white icing with a little black gel colour to get the grey shade needed for the monitor. Roll out and lift over the square cake, and smooth the icing over it.

Step 6

Once the fondant is set, using dowel rods to support, I put the square cake on top of the oblong cake.

Modelling the man:

Step 7

Using the white fondant icing, I coloured with some blue food gel and moulded it into the bottom, then rolled 2 sausage shapes for the legs. I then put the two together with a bit of edible glue.

Step 8

I made the belt out of a strip of black fondant and put round top of trousers. I made the belt loops with more of the blue fondant and cut small pieces about 1" and put round the top of the trousers. I also made a small square and used that as a pocket, then left the bottom half to set.

Step 9

For the top part of body I used plain white fondant and moulded that into the torso. For the arms, I coloured a small piece of fondant with paprika food colouring to get the skin colour.

Step 10

I fixed the top and bottom half of the body together, then I just positioned it as if he was looking inside the computer with edible glue to keep it in place. I wrote on the back with red food colouring.

Step 11

Making the keyboard

Step 12

I coloured the white fondant grey by using black food colouring to the required colour that's needed. I then rolled out the fondant and cut the shape of a keyboard out. Following a diagram of a keyboard I put indents in the fondant for the keys and set to dry, then I wrote the letters and numbers on the keys.
