Raspberry Pi Zero edible paper template

To celebrate the birthday of the Raspberry Pi in 2018?, we had Raspberry Pi Zero tray cakes.

You can make these cakes yourself, providing you have a printer that can print edible icing paper with edible ink. If you don't have a printer, perhaps you can find someone who can print the template out for you.

Depending on your preference, you can make a traditional Victoria sponge cake or a lighter blow-away cake.

Preparing the Raspberry Pi Zero cake toppers[edit | edit source]

  1. Print the Raspberry Pi Zero edible paper template onto an A4 sheet of paper.
  2. Cut the Raspberry Pi Zeros out individually using a pair of scissors, a knife or a paper guillotine.
  3. Set aside for later when you are icing the cakes.

Make a blow-away cake[edit | edit source]

Blow-away cake is a light sponge that is low in fat, due to the air that is introduced into the mixture as it's being whisked.
