Rainbow Kitty Cake – Happy Birthday Ciara!


One of the best things about being a baker, I believe, is that you can make tasty treats for your friends and loved ones. Sometimes the best type of tasty treat is a surprise one. It was my friend Ciara’s birthday last week and she was popping over to see me for a chat and a takeaway on the Friday night. But I had a sneaky little surprise in store!

I’ve known Ciara since primary school and I couldn’t let a milestone birthday go by without something special. So on the days that preceded her visit I made a rainbow kitty cake I knew she would love. I made a bright coloured tie dye rainbow sponge with a pastel watercolour rainbow buttercream exterior, topped with rainbow roses and a handmade 3D white kitty (whom I named Winston).

In this blog I break down how I made it!

Firstly I made up the madeira recipe I always use which can be found here. Then I Split the mixture into six bowls and coloured them using Sugarflair concentrated food colouring.  You only need a little bit of colour as it’s very concentrated so it goes a long way and lasts ages! I’m using the following colours;

Sugarflair Red Extra, Sugarflair Egyptian Orange, Sugarflair Melon, Sugarflair Party Green, Sugarflair Ice Blue and Sugarflair Grape Violet.

Once the cake was baked I left it to cool on greaseproof paper upside down. I do this to get a nice flat top on the cake (which becomes my base). I then trimmed it a little to make it nice and even and to try some too. Bakers perk. Look at the lovely colours!!

I then used a cake leveller to split the cake into three sections. I made up a batch of white vanilla buttercream as I thought the white would be a lovely contrast to the rainbow colours once you cut into it. Once the cake was filled I chilled it for 10 minutes to firm up. Then I did a layer of buttercream around the outside to crumb coat it. Chilled again briefly and then a ‘tidy up’ layer of buttercream and left it out on the side.

The rest of the buttercream I split into six bowls and coloured rainbow but this time with the pastel versions of Sugarflair. I then spread different colours of the buttercream around the cake and using a large scraper, went around the cake over and over again until the colours blended together in a lovely watercolour pattern!

Then with the leftover rainbow buttercream, I spooned them into a piping bag fitted with a 2D nozzle and piped roses on the top of the cake. Added a few piped ‘stars’ and sprinkles and it was done! I put the cake onto a small pink iced board with a wash glitter tape edge.

For Winston the cat, I made him out of white, pink and black Karen Davies Sugarpaste (which I love for modelling). I even made him a tiny little pink bow. I was in my own little world modelling him so I don’t have any step by step photos but if you want to know how he was made, leave a comment below and I will endeavour to make a tutorial at some point!

Once Winston was dry I placed him on top of the cake and it was complete! Ciara absolutely loved it which made me so happy. Seeing the joy on someone face and knowing it’s you that has made that smile is one of the great joys of baking.

Happy birthday Ciara. I’m so pleased you liked you cake.
