My youngest daughter Darcey was 5 last week and after changing her mind about 100 times she finally decided upon a Hello Kitty cake for her party.  It was a really easy and straight forward cake to decorate. I used a Madeira cake (recipe here) as always and this time made a square cake to cut the shape from.

First I cut out a piece of paper to the same dimmensions as the cake tin and then drew the shape of the head to fit as big as possible. Then I cut out the pattern.

Lay the pattern over the cake and make any necessary adjustments now.

Cut away the cake (this is always a great part as you can test the cake!

I smooth the very edges of the cake so that it has a softer look once iced. I do this very gently with the palm of my hand, but you can use a really sharp knife.

Once shaped cover the cake with a thin layer of buttercream

Roll out a piece of sugar paste that will cover the whole cake and down the sides. Smooth it with your palms and then a smoother tool then position the cake on the cake board or plate with a little royal icing. 

Roll out some black sugar paste and cut out two eyes. Use a small amount of icing rolled into a ball for the nose. I used yellow but was reliable informed by Beau (my 7 year old) the next morning that I should have used pink!  I corrected it after these pictures were taken! 

The whiskers are black sugar paste that has been rolled out into thin strips and left to dry over night so that they can hold their shape and protrude out over the edge of the cake. 

I made the bow with two oval pieces of pink icing. Each piece is folded in half and bunched up in the middle. I then positioned a ball of pink sugar paste on top where the two ‘ovals’ meet, hiding the join. Stick it to the cake with a little royal icing. Roll up some baking paper and slip a piece into each bow to hold it a little open allowing it to dry in that position. You can remove it after a few hours. I leave it over night.

Lastly I added the writing (which I am still perfecting!) and finished off with a little flower as Darcey is a proper girly girl! 

Happy Birthday Darcey Doodles! We love you!

  1. Hi, I love the look of this cake and would like to make it for my daughters 5th birthday next month. Was just wondering, what size tin did you use for your cake please and how many times the recipe? Many thanks, Karen

    • Hello,

      Thanks for your question. I used a 10″ square tin for this Hello Kitty cake. It would need the 1 1/4 x an 8″ recipe. Have a look at my post on measurements so you can see what I’m talking about.

      This cake came out quite small. I tend to make deeper cakes now so I would either make it twice (to ensure that the cake was nice and light and fluffy) or I would double the quantity and then cut it in half afterwards.

      Good luck with your cake. I’d love to see the end result. Post a pic of it on the CakesBakesAndCookies Facebook page ( if you get a second.


      • Many thanks for your help Emma. I am making the cake this weekend and just wanted to clarify quantities. You said for a 10″ square cake to use 1 1/4 recipe but looking on table it says 2 times recipe for 10″ – which is best please? How did you get your cake board blue too, it looks really pretty. Many thanks, will post a pic when done! Karen

      • Hello,

        I have found that when making a 10″ cake it’s best to use 2 times the recipe. I’ve recently been baking the cake in two goes, as the cake rises to a lighter texture, so bake 1 x the recipe twice. I hope that makes sense?

        To make the board blue I roll out some blue sugarpaste till it’s about 5mm thick then I dampen the cake board and cover it with the sugarpaste. Use a pizza wheel to remove the first excess sugarpaste. Smooth the surface with a cake smoother then remove the excess sugarpaste from the edges. Leave to dry (if possibke for a week) that way it is hard when you come to put the cake on top and it wont get finger prints when you handle it.

        Hope that helps


    • Hello.
      I make buttercream with 250g unsalted butter (President tastes the best) and 400g of sieved icing sugar. Add 1/2 teaspoon of vanilla and blend it all together till smooth.
      I usually use that thicker mix between cakes then add a little milk and mix it again to make it lighter and softer buttercream so it’s easier to spread over the cake.

      Hope that helps


  2. Hi Emma. Thanks so much for this. I’m just putting the finishing touches to my version of this for my little Button’s birthday party tomorrow and I’m rather please with the results. It’s the first time I’ve attempted anything like this and thanks to you instructions it’s not looking too bad at all. I think she’ll be pleased.

    • Hi Emma, I made this for my daughters first birthday yesterday. I cheated a little, and ‘googled’ a picture of hello kitty and printed it out instead of drawing it freehand! Thanks for sharing xx

    • Do it! It’s a fan cake that always how’s down well. Especially with little girlies.


    • Sorry, I don’t but why don’t you give it a go making your own template. This is a really simple shape to try out.


  3. Hi Emma my daughter would like a Hello Kitty cake but a chocolate cake with chocolate buttercream. Have you covered said cake in white fondant before and is it ok? Would the darker colour show through do you think? Thanks Debbie

    • Hi Debbie,
      I don’t think chocolate buttercream would show through as long as you keep the sugarpaste thick enough. It’s at the corners where the sugarpaste stretches that it gets thinner so roll it out so it is at least 5-10 mm thick to make sure you’re okay.

      Hope that helps


      • Hi Emma

        I just wanted to let you know that my Hello Kitty cake was a success! I used your chocolate madeira recipe and used chocolate buttercream. Nothing showed through the white icing. The cake tasted lovely. My daughter was thrilled with her Hello Kitty cake so I was delighted. Thanks for all your help.


  4. Hi Emma,

    I love your Hello Kitty cake and I’m going to make one for my niece’s 2nd birthday. Could you tell me what cutter you used for the eyes?


  5. Hi Emma. Finished this cake for my little girl’s 3rd birthday. Had a few nightmares as I used a new marshmallow flavoured fondant and it kept cracking which I hadn’t found before and I had runs with the whiskers. It’s surprising as I found this cake harder as because there is not much on it you can’t hide all the faults! Anyway from a novice follower here is a picture which I hope works. Thanks again for your posts. X

I love to hear your comments.....
