How to make an Octonauts Kwazii cake

Kwazii Cake

UK-Entertainers is always looking for ways to help parents make their child(ren)’s party as simple as but as effective as possible. With The Octonauts being hugely popular, we decided to produce simple instructions on how to make your own Kwazii Cake. Just to prove that you can do it too, we have worked with an “ordinary Mum” who has had no catering or cake decorating training to show you how easy it is to make this simple, yet stunning Kwazii Cake.


Our Mum had never designed or decorated an Octonaut cake before this project. With our simple instructions and a little time, you too can produce this wonderful cake, fit for any Octonaut party.

To make this easy Kwazii Cake you will need two round victoria sponge cakes. These can be bought (and then follow the decoration instructions below), or made using the recipe below.

Victoria Sponge Recipe
175g (6oz) softened butter / margarine
175g (6oz) (caster) sugar
3 beaten eggs
175g (6oz) self-raising flour (sieved)
1 tablespoon hot water
Cake board approximately 5cm larger than the cake tins
Jam to sandwich the two sponges together

  • Grease and line two 20cm (8”) round tins.  Cream together the butter and sugar until light and fluffy.  Gradually beat in the eggs.  Fold in the flour and add the hot water and mix until a smooth.  Divide between the two tins and spread evenly.
  • Bake in preheated oven at 180’C / 350’F / Gas 4 for 25-30 minutes until golden brown on top.  Remove from oven turn onto cooling rack until cool.  Spread jam on one cake and place second on top.

Decorations Required

  • Large ball of light blue sugar paste icing
  • Medium ball of sugar paste orange icing
  • Small balls of peach, black and dark blue sugar paste icing
  • Tiny ball of pink sugar paste icing
  • Icing sugar
  • A liquorice sweet with string liquorice wound around it
  • Apricot glaze
  • Black liquorice food pen

The amount of icing is dependent on the size of your cake, the smaller the sponges the less icing you will need. Similarly, if you are using an alternative family / favourite recipe and bake larger cakes, more icing will be needed. The photograph shows you the amount of icing required in proportion to the cake size. Your cake shop will advise you if you need any assistance.

Many good quality cake shops have sugar paste icing in a range of shades that you can buy ready coloured. A good retailer will be able to sell you larger amounts (light blue) as well as smaller quantities (peach, black). The icing is usually sold by weight so a selection of colours should be relatively cheap to buy in the quantities you require. It is always worth asking the staff for advice if you need any help or additional information. The icing is relatively cheap and it is always better to have a little too much than not enough!

Covering the cakes

  • Roll the light blue sugar paste on a flat surface that has been lightly dusted with icing sugar until it is just less than 1cm thick. Apply apricot glaze (as per the instructions on the jar) to the sponge cakes sandwiched together with jam.
  • With the cakes on the cake board, lay the light blue rolled icing over the glazed cakes and gently smooth over the surface and around the edges. Trim (and save) the excess icing from around the base of the sponge. Smooth the edges at the base of the cake.

Kwazii Decorations

  • For the Kwazii sugar paste decorations, roll the icing until it is 3-5mm thick.

  • Roll out the orange icing and using a small plate or saucer as a template, with a sharp knife cut a circle for Kwazii’s face and two triangles for his ears.
  • Roll out the black icing and using circular cutters cut a small circle for one eye and a larger circle for an eye patch. Cut the larger ‘eye patch’ circle into two just above the half way line up to make a flat top edge to the patch.

  • Roll the peach icing and cut two small circles for his nose and two small triangles (that will fit onto the orange triangles) to complete his ears.
  • Roll a tiny ball of pink icing in the palm of your hand for the tip of his nose. Unroll a length of liquorice and cut so that it fits exactly across Kwazii’s face.

  • Roll the dark blue icing and with a sharp knife cut a hat shape. With some of the trimmed light blue sugar paste cut a small circle for the hat badge.

  • Warm water acts as a glue to fix the sugar paste shapes to the cake – but use sparingly to avoid colour running.
  • Use a pastry brush to apply a little warm water onto the back of the large orange circle and position just below the centre of the cake. Add the orange ear triangles and dark blue hat with water too.

  • Stick the peach triangles onto the ears using a small amount of water and also a length of liquorice across the top third of Kwazii’s face.

  • Attach the light blue circle for a hat badge, the small black circle for his eye and the larger piece of the cut black circle for his eye patch.

  • Next use the two small peach circles and a tiny rolled ball of pink icing to make his nose. Using the black food pen add three whisker spots on each cheek, a mouth under the nose and the Octonaut logo on the hat badge.

  • Add a tiny ball of white icing (made from icing sugar and a drop of water) to the eye to add the glint and you have a complete Kwazii Cake. Ideally leave in a cool place out of sunlight to allow the icing to firm up and all pieces to stick together before serving.

This was the first time our ordinary Mum had decorated a Kwazii cake. UK-Entertainers hope that this article has given you confidence to decorate your own Kwazii cake using our step-by-step instructions. We hope you agree that this cake is simple, yet effective and will capture the imagination of any Octonaut fan.

  1. This is fabulous. I’m not good at baking myself but you’ve really made it so much easier here with this very detailed instructions.
    You make it look so easy. There’s definitely going to be a happy little boy in August.

    I actually made this cake tonight, thank you so much for the straight forward instructions.
    My husband thought it looked exactly like the picture i downloaded from your sight.
    Also the person I made it for was crying she liked it so much.
    Thank you again.

  3. […] it the best cake I had ever made! (That was before eating it though…!) The instructions are here for any other mothers who have Octonaut-mad […]

    Just spent a very enjoyable evening making this for a favourite 3 year old’s birthday party tomorrow. Really good instructions and my husband did an excellent Octonauts badge. We didn’t have a liquorice pen so used a brush and cocktail sticks with food paste. We also didn’t have a liquorice wheel so rolled a strip for the eye patch. Fingers crossed it’s a hit tomorrow but we’re pleased so far! Thanks!!

    (more characters please…!)

    Thank you for such clear and straight forward instructions. For a non-baking Dad the result has been spectacular – my sons 3rd birthday will no doubt be extra special for its Octonauts themed cake. Awesome – thanks again.
