For at least a week I had the same after work routine.

Come home, change into something more comfortable then mix up another batch of flour and water and carefully apply the newspaper strips to my craft project.

What was it you ask? It was a piñata cake, but not just any pinata cake, a doodle pinata for my friend's hens party.

Sadly I can't seem to find any photos of my work of art but you needn't worry because I have a much better looking version for you today.

This rainbow pinata cake is extra special because today is my Birthday!

That's right today is the big 2-8 which means I have just two more years to come up with the-best-cake-ever for my 30th. In the mean time, I'm keen to celebrate this one with a whack bang and hope the celebrations spill over the next few weeks (get it...spill over like the filling in a piñata - oh yes I'm witty on my Birthday!).

A few weeks ago, my sister sent me a pic of a piñata cake and I knew it's what I had to make for my Birthday blog cake.

Just to fill you in, I get a Birthday cake for the day and a Birthday cake for the blog, ok and sometimes I bake an extra cake over the weekend closest.

What can I say, I love mud cake!

My rainbow pinata cake was seriously easy to make and oh so much fun.

The hardest part was probably choosing what to put inside. I settled on mini m&ms and freckles surprisingly fast.

Don't ask me why, they just jumped off the supermarket wall into my hands.

Preparing the cakes
Preparing the cakes

I didn't want the cake to just look fantastic I wanted it to be delicious too so my piñata cake shell is made of macadamia and lime pound cake and iced with lime cream cheese icing.

You could use buttercream icing. 

If you're not a fan of lime or macadamia, try out a pound cake recipe. You can really use any recipe you like as long as it's a dense cake so it won't collapse when you hollow it out.

You will need some sort of round dish to bake the cakes in.

I used my pudding tin but had to bake the cakes one at a time and wash it out in between the two.

It wasn't a big deal, but if you have two the same size or can borrow an extra one, it makes it easier.

Side note, someone has invented a Pinata Cake Pan which could be rather handy if you don't have the right shaped cake tin.

Once the cakes have cooled you will need to slice off the top and make sure that they're both the same height so that their circular tops match up.

You may need to trim one down to match.

Then, carefully dig out the middle of each one leaving at least a three centimeter border because you don't want the piñata cake to collapse before it's smash cutting time.

I challenge you to do this part without eating all the offcuts sampling the cake.

Stuffing the piñata

Next up, fill one of the halves with your treats of choice - mine were m&ms and Freckles.

You can use whatever you like but don't put anything too big in there or it will be really hard to cut the cake later.

Even the Freckles provided a little bit of a challenge.

You could even try filling it with something like jam & cream.

Pipe a thick border of icing around the outside of the base cake.

Securing the lid

Then secure the lid.

I then covered mine with a thin coating of white icing to lock in all the crumbs and make decorating easy.

Once that was set it was time for the fun to begin.

Four colours of icing
Four colours of icing

To me, it's not really a pinata without crazy colours so I went all out with my vanilla cream cheese buttercream icing (you can use any thick icing that pipes well - here's how to make buttercream icing).

So I could use all four colours at once, I wrapped each one in a plastic wrap sausage and tied off one end and twisted the other end tight.

The snip

Then I gathered the twisted (not tied) ends all together and gave them the snip then carefully dropped them into my piping bag fitted with the star icing tip.

After squeezing out a bit of icing to make sure all the colours were coming out together I went to town decorating. Feel free to go crazy with this step. It is a fiesta after all.

My icing was a little bit runny so drizzled down the sides a bit but I wanted it to look like it was draped the way the crepe paper hangs from a paper pinata.

Now for the best bit...

The cutting! I imagine it would be pretty exciting to cut into it if you didn't know it was filled with goodies. Ok, I'll admit it was pretty exciting even though I knew there was hidden treasure inside.

Here are a few more homemade party food ideas:

  • Make your own jelly lollies
  • Homemade lemon cordial
  • Fool-proof vanilla cupcakes

    Great looking cake!! My question is regarding the icing. I think everything seams pretty straight forward with making the icing, but how hard was it to get it rolled in the clingwrap (sausage) stage. Thanks for sharing

      Hi Tammy. Thanks so much! Wrapping the icing is really simple. If you need a demo, I made a little video here: https://www.clairekcreations.com/2012/11/mess-free-icing-with-a-piping-bag/

    Sorry Claire, but I too am wondering why both cakes have to be hollowed out if only one half is filled with the goodies? Would this not cause the cake to collapse or did you pile the treats into a mound (not depicted in your picture)?
    Do you have an alternative icing recipe which does not use cream cheese? Can't wait to try it. :)

      Hi Ivi - I hollowed out the top cake as well because I wanted it to look hollow when you cut into it like a piñata. You don't have to to get the filling in but I thought it was more authentic.

  8. Janet says

    Awesome job on the cake! I'm a cake decorator and always looking for some new ideas. Why are both cakes hollowed out if you are filling only one? I understand that if you filled both you wouldn't be able to put them together but it seems like a lot of air space in the top. Or do you fill it with enough candy that it is a huge mound? It didn't look that way in the pictures you provided.

      Thanks Janet! I wanted it to be totally hollow in the middle like a pinata but I guess you don't really have to hollow out the top if you don't want to. You could mound up the candy in the middle.
      I'd suggest making cake pops with the bits of cake that you scoop out. Yum!

  9. Lynda says

    April 25, 2013 at 9:20 pm

    One quick question. If you fill one half with lollies, why do you need to hollow out the second cake?

      Thanks Lynda! I'd love to see a photo when you finish! Re the hollowing... I didn't really thing about it. I guess you don't have to but I wanted it to be a round hollow in the middle to look more like a pinata. You could mound up the filling too.

    LOVE THIS CAKE!!
    Some questions... is icing sugar also known as confectionery sugar?
    What is Caster Sugar?
    Is macadamia meal just ground macadamia nuts?
    Is this cake cooked to be on the 'dry side' in order to hold up better?

    Thanks

      Hi Brooke. Thank you!
      In answer to your questions....
      Icing sugar is also known as confectioners sugar.
      Caster sugar is super fine sugar.
      Macadamia meal is ground macadamia nuts (you could substitute almond meal if you like).
      Not necessarily dry but a dense cake like pound cake is best as it's nice and sturdy.

    Hi,

    This cake looks awesome and my kids want me to make it for my hubby, have you another recipe for the cake as my hubby isn't keen on lime and stupid question would a square tin work also as I don't have any pudding basins

      April 23, 2013 at 5:08 pm

      Hi Louise. I've just sent you an email. I'd recommend a pound cake because they're nice and dense. You could use a square but make sure it's not too big or it may collapse when you scoop out the inside.
