Unicorn party tips and ideas, plenty of sparkle ahead.

Unicorn party – tips and ideas.

Pin for future reference!

We have just survived thrown a unicorn party! So I thought I’d write it up while it was still fresh in my memory!

The cake.

I made cupcakes and had a unicorn party cupcake decorating station. I ordered some candy eyes on ebay, and then had marshmallows cut in half for noses and a sweet stick for a horn and the idea was that the children could assemble them themselves. I made the fairy cakes using my fail safe recipe.

unicorn party ideas.

I got the pretty cases from the Range, I think they were called ‘Tulip cases’ and then I iced them with butter icing and put them in tin ready to go to the party and be decorated there.


6 oz self raising flour
6 oz caster sugar
6 0z butter
3 eggs
1 teaspoon of vanilla essence


Pre-heat oven to 180 centigrade fan
Cream the butter and sugar
Add the eggs, flour and vanilla essence
Mix well until pale
Using a large spoon, (and another to scrape the mixture off), put a spoonful into a muffin tin pre-lined with cases, if there is any left over, go back and top them up.
Bake for 12-16 minutes until the top is golden and a skewer comes out clean.

For the butter icing.

50z unsalted butter, (at room temp)
10oz icing sugar, (sieved)
1-2 tbsps milk


Beat well until pale and smooth.
Add food colouring tiny bit at a time until desired shade is achieved.

I don’t have a photo of them decorated though, as I was in the depths of unicorn party chaos and had left my Mum on duty! Might have to make some more just for photos! 😀

For the main cake, I don’t have exact quantities I’m afraid. I used the same basic recipe as above and just kept doubling until I had enough. Read on to see why you may want to use your own!

Unicorn party cake

The cake looks pinker when you cut into it, less really is more when it comes to these gel dyes!

I made 3 layers, two I coloured with gel icing colour, I used sugar flair in Fuschia that I bought on ebay. It is serious stuff and believe me when I say that a little, and I mean a scraping, goes a long way, so add it gradually until you get the colour you want. It will look paler after baking.

You know it’s serious stuff when it comes with a hyperactivity warning!! (Hence why I use it so sparingly!)

I then sandwiched the cooled layers with pink buttercream and coated the whole cake with it, a crumb coat.

After that, I coloured some white roll out, (fondant), icing with some more of the gel colour. It will make the icing a bit sticky so just add icing sugar until you can roll it out without it becoming a big sticky mess. Then drape it over your crumb coated cake.

Luckily the clouds were in the creation to patch the holes!!!!

This was the worst bit. Even with a cake smoothy tool thingimajig, (technical term), and I ended up having to patch a few holes. 😀 Also, I would use a recipe that you know works. For some reason, when I make cakes in tins now, I end up with a raised middle and thin edges. It’s been driving me crackers so if you have any ideas as to why please tell me in the comments! I ended up filling in any spaces with butter icing, which is fine but so unhealthy!!! 😀

I’d saved some white icing and rolled it out thinly before cutting out free hand cloud shapes and sticking them on with a little water, these were fantastic as they looked great.*

*hid the worst of the horrible patching job!

Colouring the butter cream. Mmmmmmmm yummy!

After this, I decorated the cake using well known chocolate sweets in shells, sticking them on with the left over butter icing. There were a lot of them, I’d previously sorted the colours out so there were only the bright rainbow colours. We were eating the brown ones for weeks after!

The finished cake! Complete with rainbow!

I ended up just buying the unicorn to stand on top. I usually end up stressed and creating until the early hours at birthday time, so to make sure I enjoyed the actual unicorn party more, I decided to take a short cut, it was very effective and my daughter got to keep the toy after. Win win!

For a party game, I made ‘pin the horn on the unicorn’ board. I started with some white mounting board also from the Range and drew out the outline of a horse, first in pencil and then went over in black pen.

Unicorn party games

I know I know! It’s not the best looking horse but the 6 year olds loved it! 😀

Next I brushed the mane and tail with pva glue and sprinkled on lots of multicoloured glitter. After that I cut out a horn from cardboard and when the children were ready to play, I simply placed a scarf over their eyes and spun them round a few times and let them loose. They loved it and the idea is that at some point we get around to colouring it in and then she can have it on her bedroom wall.

Just a warning, the glitter gets EVERYWHERE!

We also did a pass the parcel with unicorn wrapping paper and unicorn gifts inside. Another tip is to not wrap it last thing at night, there were a few children that didn’t get their sweet, oops! Luckily we had spares!

The goody bags had unicorn stickers in, and were rainbow coloured paper bags and I had got stickers from ebay that matched the invitations, (all unicorn of course!), the children got to take their unicorn cakes home in pink and white striped bags and we cut up the main cake to hand out to parents and give to visiting family.

This is what the cake looked like inside. Note the filled in edges due to rising issues!!!!

Decorations: I ordered pink and silver balloons from ebay and I also found some big pink paper frill ball things that you can see in the picture above. It was a little hard to decorate the village hall so it was mainly just balloons on the bouncy castle, which they loved of course!

I’d also been burned by ebay by not checking the sizes of the things I was buying and ended up with some of the smallest plates you’ve ever seen! Luckily I am a hoarder and had loads of princess stuff left over from a previous party to use for the table! 😀

All in all, we loved the unicorn party, and so did everyone that came, every year I swear I’m not going to do another party next year, but, a little like childbirth, I soon forget the trauma and start planning the next one! 😀

    This is awesome! What a fab cake and a great blog post. So amazing! It’s a cake my little girl would love.

  2. January 30, 2017 / 9:06 am

    I love that cake! I wonder if I can convince my son he wants a unicorn party? He loves Go Jetters, so maybe a Ubercorn cake?! *goes off to start planning* #bigpinklink

  3. January 30, 2017 / 9:14 am

    So cool! And such a great idea to use the smarties for the rainbow! I’m pretty sure there’s a unicorn cake in my future somewhere! #BigPinkLink

  4. January 30, 2017 / 9:17 am

    Love the unicorn cake! I just designed unicorn items in my online store, it must be a unicorn kind of month! #bigpinklink

  5. January 30, 2017 / 9:18 am

    I’ll be bookmarking this for the future #bigpinklink

  6. January 30, 2017 / 9:25 am

    aww you are the party hostess extraordinaire you really are! My children would have loved me to have been that unicorn party mummy – amazing – though t be honest they’d still love it if I made that cake now – though it’ll have to be gluten, dairy and egg free – yes that is why I struggle with baking these days! #BigPinkLink

  7. January 30, 2017 / 11:54 am

    Such a fab idea for a girls birthday! I would love a unicorn cake like that! #bigpinklink

  8. January 30, 2017 / 12:10 pm

    I just don’t think I have the skill required to make such a beautiful looking cake. Anything that looks so good must be good for you!! Right?? #bigpinklink

  9. January 30, 2017 / 12:16 pm

    oooh you did good! Congratulations on the cake 🙂


  10. January 30, 2017 / 12:20 pm

    I have a feeling my daughter will be wanting a unicorn cake for her upcoming 5th birthday! Luckily (as much as I enjoyed making her earlier cakes before we had number 2) she has an aunt who is fab at making and decorating cakes. Love the party ideas.

  11. January 30, 2017 / 12:27 pm

    That is such a cute cake!! I did loads of baking, especially birthday cakes when I was on maternity leave with Amelia but since having Wills (and joining Slimming World) I’ve lost my mojo a bit… you’ve inspired me to get creative for Amelia’s 3rd birthday in March!! #bigpinklink (p.s. so so sorry to hear about Monty xx)

  12. January 30, 2017 / 12:41 pm

    That cake is amazing! What a talent you have for baking – I made some cup cakes recently and four survived. It looks amazing and I love the idea of pin the tail on the unicorn. Love your creative ideas, they are so inspiring. #bigpinklink

  13. January 30, 2017 / 2:00 pm

    I just wrote an article for Red Tricycle on the many uses and buys of Unicorn poop- who knew…

  14. January 30, 2017 / 2:41 pm

    That is absolutely amazing! I’ve always loved unicorn things – I’m going to gently encourage my daughter to like unicorns too in the hope that we can do things like have a unicorn party. The cake looks fantastic, I wish I’d been there!

  15. January 30, 2017 / 2:44 pm

    That cake looks amazing! I’ve always loved unicorns and hope that my daughter will too – I’d love to throw a unicorn themed party for her 🙂

  16. January 30, 2017 / 4:20 pm

    This is incredible! It’s my husband’s 30th in a few weeks… so tempted to make the cake! #bigpinklink

  17. January 30, 2017 / 6:28 pm

    I love the cupcake decorating station idea, and I love even more how you compare the trauma of a children’s party to child birth! It’s nature’s way that we forget the pain! Although my brother offered to make my daughter’s cake and after beating myself up for ages thinking as a proper mother I HAD to do it, I took him up on his offer and the chocolate orange cat was well worth it. #bigpinklink

  18. January 30, 2017 / 7:35 pm

    Ok I’m really hungry now and I seriously need cake! That cake is AMAZING! You are a clever lady! Alison x #BigPinkLink

  19. January 30, 2017 / 9:09 pm

    When I saw this photo of the beautiful happy unicorn, I immediately knew it was your post! How beautiful. You always do the most fun and happy cakes. #BigPinkLink

  20. January 30, 2017 / 9:29 pm

    Wow, that is stunning! Glad the party went well 🙂

  21. January 30, 2017 / 9:36 pm

    oooo I want a unicorn party! Definately gonna make hubby throw me one for my 31st hahahaha! #bigpinklink

  22. January 30, 2017 / 10:39 pm

    Mary Berry would be proud! Haha! Unicorns are everywhere at the moment aren’t they? Am finding myself being suckered in by it… may keep your recipe for my birthday this year 🙂 #bigpinklink

  23. January 30, 2017 / 11:49 pm

    Oh my goodness this is an amazing post, you’ve gone to so much effort with it! I hope she had a lovely time, all the activities look awesome and those cakes!!!

  24. January 31, 2017 / 9:57 am

    You went to so much trouble and the cake looks amazing! You’ve set the bar high among your Mum friends, they’ll not be able to do a quick iceover on a Sainsbury’s cake and look you in the eye 🙂 Jo #bigpinklink

  25. January 31, 2017 / 12:14 pm

    I keep seeing lots of unicorn cakes and party ideas! It’s Rory’s first birthday in a couple of weeks, although he’s not having a unicorn theme I’m going to attempt to make his cake! I hope it turns out as well as yours! #bigpinklink

  26. January 31, 2017 / 12:54 pm

    The cake looks fab! I bet all the little girls loved it, especially the decorating station, very professional! #bigpinklink

  27. January 31, 2017 / 4:50 pm

    This is completely awesome! did you wear THE dress? #xoxo bigpinklink

  28. January 31, 2017 / 8:00 pm

    My girls are OBSESSED with unicorns, they would absolutely LOVE this! Obviously there’s not a hope in hell that I could make it, but I’m hoping that I can find someone who can!! #bigpinklink

  29. January 31, 2017 / 11:50 pm

    I absolutely love this! You always seem to make tasty looking stuff. I made some soup the other day, it was greeny-brown 🙁 it tasted fine, if you could get past the offensive appearance!


  30. February 1, 2017 / 10:12 am

    Unicorns are such a thing right now, even with my teen. Full on Wow! Fantastic cake and loved that you had the theme running through the games too. #BigPinkLInk

  31. February 1, 2017 / 2:11 pm

    You’re so creative! Cake decorating is a great idea for a party too. Good job 🙂 #bigpinklink

  32. February 1, 2017 / 2:15 pm

    Wow, well done. This all looks amazing, can you do come my kids birthdays?

  33. February 2, 2017 / 3:55 pm

    HOw fun! I love the cake you made you did a great job!

  34. February 2, 2017 / 9:24 pm

    Can I book you for my daughters birthday in March? She loves unicorns too! The cake looked great and it sounds like you know how to throw a birthday party too #bigpinklink

  35. February 3, 2017 / 12:40 pm

    WOW!!!! The cake looks awesome-it all looks awesome!! You certainly went to a lot of trouble, so I’m glad it all went really well, and everyone loved it! I’d quite like a unicorn party for myself, but maybe I’ll have an adult version when the children are in bed-all the pretty cakes, but also wine and gin?! #bigpinklink

  36. February 3, 2017 / 1:34 pm

    That looks like an amazing party! Well done! Love the cake. I’ve found some cakes rise in the middle more the same as you, I found using a smaller cake tin helped – a much more even top, with less to cut off. I think I also add a bit more baking powder and less butter (and cocoa) last time and it was my best… Not sure if any of that helps!! #bigpinklink

  37. February 3, 2017 / 1:35 pm

    Looks great Louise! I think my daughter would love this too so will be back in the summer to check it out again!! #BigPinkLink x

  38. February 5, 2017 / 2:04 pm

    Looks amazing! So creative and your party bags and decorations sound great too. What a lucky girl! Hope you had a lovely day. I can’t wait to do this sort of thing with my daughter! Xx #bigpinklink

  39. February 5, 2017 / 8:38 pm

    I like the twist on the “pin the tail on the donkey”, good attention to detail.
    Do you think the kids will remember/appreciate how much effort we put into these things for them?
    My wife and I were up every night for a week before our son’s superhero party!

  40. February 6, 2017 / 9:18 pm

    Your cake looks fabulous. I like the creative use of filler I am a huge unicorn fan, so would have apprecited this type of party #bigpinklink (p.s sorry for being late with my comment)
