You've been tasked with making your kid's birthday cake this year and looking for some showstopping inspiration, well, you've come to the right place. 

From a no-bake train cake for those with a fear of ovens and soggy bottoms to a clever anti-gravity cake that will boggle your little ones' minds, we've got you – and your small party guests – covered with our range of statement cakes to stand proudly on your kid's party food table. And you'll be glad to know that all include top tips for making your kid's birthday cake that little bit easier.

There are ideas to suit everyone from total novice bakers to those who could give a Bake Off contestant a run for their money, all of which will be the star of the show amidst all the other party buffet food. And speaking of Bake Off, we've got cakes from the tent's most famous inhabitant, Nadiya Hussain, and another show winner, Jo Wheatley. 

We also spoke to expert baker, Sophia Butler, who makes cakes for children's parties at The Sugar Tea Room to get her take on making a kid's birthday cake; "Vanilla cakes are the easiest to bake and decorate," says Sophia. "A simple all-in-one recipe, with equal flour, butter, sugar, eggs, and a splash of vanilla extract makes the best sponge. Add some jam or buttercream in the middle and the cake will be perfect!" 

Here are our best kid's birthday cake recipes and ideas for you to recreate at home...

Birthday cake ideas for kids

Jo Wheatley’s rainbow vanilla sponge

A bright winner – and one that is perfectly acceptable if it looks a but 'rustic' 

1. Jo Wheatley’s rainbow vanilla sponge

Serves: 8-10 | Prep time: 45 mins | Cook time: 25 mins

This adorable and very fun cake comes courtesy of The Great British Bake Off winner Jo Wheatley (you'll need to cast your mind back as far as 2011 for that one). It's a great one for less confident bakers, as the sponge is a basic – and classic vanilla, and there's no fancy fondant work – it's just about ready-to-roll icing and Smarties. You'll need some blue food colouring for the buttercream. Making the rainbow is a little fiddly but not at all complex, and is secured in place with cocktail sticks, disguised with buttercream clouds.

No-bake train cake

Too cute and zero baking – we're making this immediately, birthday or no birthday

2. No-bake train cake

Serves: 6-8 | Prep time: 1 hour 

If you're not so hot on the old baking skills, you'll be on the right track (sorry) by putting together this showstopper made entirely from shop-bought cakes and biscuits you can find at any supermarket – or even in the corner shop if you're tight on time. It's a chance to exercise your creative skills without concerns for soggy bottoms or burnt sponges, and it's super fun to put together with the kids. The result is next level.

Pink wafer ice-cream cake

A fabulous cake effect with the vanilla ice cream sandwiched between strawberry 'sponge' – you'll just be needing a deep baking tin

3. Pink wafer ice-cream cake

Serves: 12 | Prep time: 1 hour, plus overnight freezing

Made from shop-bought strawberry and vanilla ice cream (though you could switch out for other flavours), this ice cream cake is simpler than it looks and will be a triumph with the kids. Best suited for a party at home, as it won't easily be transportable, make it the day before the big reveal, as it needs to be set in the freezer overnight. Great for summer parties.

Oreo layer cake

An Oreo fan's taste of paradise

4. Oreo layer cake

Serves: 12-14 | Prep time: 1 hour 30 mins | Cook time: 55 mins

Oreo enthusiasts will be utterly thrilled with this towering Oreo cake because it's not just topped with Oreos (that do indeed have sprinkles stuck to them, just when you thought they couldn't love them more), but also contains them crushed into the frosting. Delicious!

Stained glass cake

One for older kids, who will be better equipped to enjoy these not-actually-glass shards

(Image credit: TI Media Limited)

5. Stained glass cake

Serves: 16 | Prep time: 1 hour 20 mins | Cook time: 1 hour 10 mins

A stained glass window in cake form? Sure. This glorious design would work just as well for an adult birthday celebration. The almond sponge is a relatively simple one (note to self to check any nut allergies before serving) and the shards are made from melted boiled sweets – multi-coloured obvs – with liquid glucose. The best bit? Once set and cooled, smash them into shards to decorate the cake.

Nadiya Hussain's confetti birthday cake

Hidden fruit in the frosting means this cake is practically a health food…

6. Nadiya Hussain's confetti birthday cake

Serves: 12 | Prep time: 35 mins | Cook time: 25 mins

Nadiya knows a thing or two about a special celebration cake (as the late Queen would have testified), and our favourite thing about this pastel wonder is that the colour isn't from artificial food colouring – the pink comes courtesy of using real strawberries. So, it's basically good for you, right? A simple bake perfect for amateur bakers. Just don't forget the sprinkles.

Digger cake

Simple and adorable – let's do this!

7. Digger cake

Serves: 6-8 | Prep time: 40 mins | Cook time: 20 mins

Make a simple cocoa sponge (or even buy one – bad bakers rejoice!) and transform it into this seriously impressive digger cake using chocolate fingers, crumbled Oreos, and your kid's favourite mini toys. The chocolate finger fence keeps all the 'rubble' in place. A bit of housekeeping – don't forget to give those toys a good wash and a soak in boiling water to sterilise them. Oh, and remind the little ones that they aren't actually edible…

Smarties chocolate finger cake

A classic party cake, and a real treat for the taste buds

8. Chocolate fingers cake

Serves: 8 | Prep time: 30 mins | Cook time: 25 mins

An absolute classic kid's birthday party favourite is this choc sponge, wrapped in a fence of chocolate fingers and topped with a ton of Smarties (don't be shy) and other sweets. Choose a selection – Maltesers, marshmallows, Dolly Mixtures, jellies, whatever takes your fancy – and they can either be compartmentalised into sections or just all piled on together for ease. Divine.

rainbow layer cake

Another classic delight of a cake

9. Rainbow cake

Serves: 15 | Prep time: 15 mins | Cook time: 40 mins

Easier than it looks, the biggest challenge here is finding five cake tins to bake the different colour sponges (and remembering how to make colours from other colours, to not overspend on food colourings!). Stick the sponges together with a layer of lemon curd for a little tang and some extra sweetness, spread over the frosting, roll in sprinkles, and await squeals of delight.

Birthday present cake

One for those who know their way around a piece of fondant – isn't it glorious?

(Image credit: Future)

10. Birthday present cake

Serves: 8-10 | Prep time: 1 hour 30 mins (plus various chilling times) | Cook time: 25 mins

One for those who are a dab hand with the fondant, this impressive creation takes a bit of patience and skill. Still, the step-by-step hand-holding instructions mean even those with neither can give it a good go so, if you fancy channeling your inner Bake Off contestant, then knock yourself out. It's a labour of love and one that is well worth it.

Polka dot cake

Yep, we're going dotty for this bake

11. Polka dot cake

Serves: 16 | Prep time: 3 hours | Cook time: 35 mins

One for those with plenty of baking kit (think a cake pop-making machine) at their disposal, and a reasonable amount of time and skill, this stunning cake is well worth going the extra mile. After making the multi-coloured cake pops, they're added to the regular batter, for a brilliant polka-dotted sponge effect. Once cooled, the cake is covered in buttercream and circles of multi-coloured cut-out fondant. A spot of joy.

Marshmallows chocolate cake

You can never go far wrong with a marshmallow

12. Chocolate and marshmallow birthday cake

Makes/serves: 10 | Prep time: 40 mins | Cook time: 55 mins

An easy one that will be every bit as loved as a fancy, time-consuming bake, this choc cake topped with fresh cream and marshmallows won't keep long, but that's hardly a worry as the kids will likely snaffle it in record time. The sponge contains ground almonds so be sure to check in about the party guests' dietary requirements.

Chocolate giant cupcake

If there's one thing we enjoy more than a cupcake, it's a giant cupcake…

13. Giant chocolate cupcake

Serves: 12 | Prep time: 25 mins | Cook time: 50 mins

A cupcake for 12 you say? And why not? This recipe could be adapted for any flavour sponge and variety of toppings. The key piece of the kit is a giant cupcake mould (these can be bought on Amazon) – other than that, it's the same as prepping any other cake. Cover with a chocolate ganache and pipe buttercream on top and you're good to go.

Chocolate cola cake

We don't need an excuse to buy cola bottles, but we're always glad to have one

(Image credit: TI Media Limited)

14. Chocolate cola cake

Serves: 12 | Prep time: 1 hour | Cook time: 30 mins

An excellent use for that flat bottle of cola in the fridge (or if you don't have a flat one, make sure you pour it out a while in advance to de-fizz a little), this basic choc sponge is livened up with a glass of iconic pop, giving it the edge over a bog standard chocolate cake. Decorate with cola bottles (feel free to add fizzy ones too) and other chocolates of choice.

Pinata cake

Well, this will be a nice surprise when sliced…

15. Piñata cake

Serves: 12 | Prep time: 1 hour | Cook time: 25 mins

If there's one thing a kid loves more than a piñata, it's a piñata in cake form. And, while this might feel complicated, it's essentially a regular sponge, hollowed out, filled with a mix of sweets, and covered in buttercream. Never mind the kids, we want one for our next birthday celebration, please.

Giant rainbow cupcake

The kids will be over the moon, never mind the rainbow

16. Giant rainbow cupcake

Serves: 8 | Prep time: 50 mins | Cook time: 45 mins

Using a giant cupcake mould, this is a rainbow cake in a new guise. The recipe uses nine multi-coloured layers, but you could do less to save time and lessen the fiddly stuff. Sprinkle with Skittles and any other candies of choice (being colourful is the only stipulation) and stick a big candle with the birthday child's age on top. Delightful.

pick & mix chocolate and sweet cake

A penny mix up, in cake form

17. Pick and mix chocolate and sweet cake

Serves: 8 | Prep time: 30 mins | Cook time: 45 mins

A choc finger cake turned into a pick and mix counter? The dream. Use chocolate jazzies, Love Hearts, white chocolate mice, and all the classics, to fill separate sections of the topping. Looks so effective, and tastes so good. Choose whatever sponge you fancy, though chocolate is always a winner. The kids will be more fussed about the toppings, so it's even ok to just buy the cake. Win-win.

rocky road cake

Don't mind if we do

18. Rocky road cake

Serves: 6 | Prep time: 25 mins | Cook time: 55 mins

Didn't think Rocky Road could be bettered? It just was… This is a chocolate sponge but with all the added joys of smashed biscuits, choc chips, and raisins (feel free to add glace cherries too, and to swap the digestives for ginger nuts, amaretti biscuits or any other cookies of choice). Drizzle over melted white choc and decorate with mini marshmallows – and you've got yourself a sure-fire hit.

Anti gravity cake

19. Anti gravity cake

Serves: 12 | Prep time: 45 mins

A clever-looking cake that requires very little cleverness as a baker. Make (or buy) a basic chocolate sponge, slather it in buttercream, pop some straws in it, and cover those in buttercream too, then stick on a very generous amount of M&Ms or Smarties. The kids will be mad about it and you'll feel like the most popular person in town, which is always nice.

Reese's Pieces peanut butter cake

A cake worth going nuts over

(Image credit: Future)

20. Reese's Pieces chocolate peanut butter cake

Serves: 16 | Prep time: 45 mins | Cook time: 45 mins

It goes without saying that this one needs an allergy warning but, now that we've got the non-fun stuff out of the way, let's crack on with celebrating this glorious cake. A rich chocolate cake covered in peanut butter flavoured buttercream, topped with a silky chocolate ganache, and topped with halved mini peanut butter cups in the ultimate celebration of America's iconic chocolate bar. Yes, please.

Chocolate marble cake

Classy and very, very chocolatey

21. Chocolate marble cake

Serves: 12 | Prep time: 1 hour | Cook time: 1 hour 15 mins

A somewhat sophisticated bake that could be best suited to older kids and teens. The cake is marbled with a mix of dark choc and white choc sponges, covered in Nutella buttercream and a chocolate glaze, and decorated with homemade marbled chocolate shards. And that's rather a lot of chocolate, not that there's such a thing as too much chocolate, of course.

Giant KitKat cake

If there's one thing better than a KitKat, it'll be a giant KitKat

22. Giant peanut butter Kit Kat Chunky

Serves: 12 | Prep time: 25 mins, plus setting time 

A fabulous-looking 'cake' (ok, actually a massive biscuit) that requires zilch in the way of baking.  It just needs wafer biscuits (we recommend hazelnut flavour, but it's down to personal preference), smooth peanut butter, and melted milk chocolate. Oh, and some cookie cutters to write KitKat on top of the cake. Wonderful.
