The Hungry Caterpillar 1st birthday cake

Firstly apologies, I’ve been meaning to write this post for weeks and Izzy is now 13 months old!

Anyway here it is! I had wanted to make Izzy a Hungry Caterpillar cake for her first birthday since spotting one on Pinterest when she was only 3 months old, when she was a little older her aunty & uncle bought her The Hungry Caterpillar pop up book and she LOVES it so it was definitely a go.


The cake I saw on Pinterest is here and that’s more or less what I was planning to do. I made a batch of cupcakes and then my piping bag broke and well I got really annoyed and frustrated as it was the night before her party and ended up rethinking the whole idea and what I ended up with was this:


And I actually preferred it this way in the end although as someone who is far more into the taste of food than the look of food I did find it harder than it needed to be but I enjoyed it.

Heres how I did it:

You will need :

The ingredients for one Mary Berry traybake ( recipe can be found here ) I added green colouring to my traybake to make a vibrant green flesh for my caterpillar.
500g of fondant icing sugar
Icing colour ( I bought red red and kelly green from Hobbycraft)
Basic buttercream using icing sugar and butter with vanilla extract (Nielsen Massey is best) – I used leftovers from cupcakes I was making for the party so unsure of quantity.
1 cake board or piece of cardboard covered in white paper.
Cadburys chocolate fingers
Chocolate sprinkles

Follow instructions for traybake and when cooked leave until completely cooled.
I cut out a basic caterpillar body and head from my traybake – reserve the leftover sponge in case of errors or just to munch on later.
Mix up 1/2 of your fondant icing following instructions on packet and split into two, using a cocktail stick put green colouring into one 1/2 of the icing and knead to mix the colour through making one a dark green and the other 1/2 paler. Roll out and cut into strips. Spread a little buttercream over your cut out caterpillar body and then wrap in your green icing alternating between the darker and lighter colours. Reserve any leftover icing for extra decorations such as fruit for your board.
Mix up the rest of your fondant icing and split into two, use your red colouring to make a very vibrant red icing for your caterpillar head and leave the rest white.
Spread some butter cream and wrap your caterpillar head in red icing and attach to body using more buttercream if necessary. Use cadburys fingers to make legs and antenna as well as the body for your butterfly. Use leftover icing to make fruit, leaves and a butterfly as well as to make name or message for cake. I used chocolate sprinkles to make the seeds on my strawberries and my apple stork. Use dark green icing to make eyes and a chocolate chip for the nose.

To make your cake have a little sheen brush on some lemon extract or juice with a pastry brush.

I used some leftover sponge and buttercream to make a patch of grass but I don’t think it’s necessary.


She did like the cake although looked a little shocked at first, and kept wandering over to look at it every chance she got:


All in all it was a success although far from perfect which you will notice if you look closely but I loved the fact that I made her a special first birthday cake. I’m guessing as the years go on I will have to become more elaborate!
