Well is this just simply a blast from the past? 10-year-old me would be so proud that I managed to re-create this retro school sprinkle cake recipe in a gluten and dairy-free version. Before my food intolerances were defined, I would always eye up this cake when in line at primary school lunch time. I’d never be that worried what was for mains, but my eyes always darted to the dessert. We always had a choice of two – and I knew which I was longing for. I’d always be so gutted if I missed the last slice! I had a massive sweet tooth from a young age you see.
I’ve spoken to many people and everyone remembers this cake – even those several generations above mine. My original birthday cake idea wasn’t going to plan – due to some missing decorations – so I decided to whip this up last minute instead. I actually mentioned this to my nanna on the phone right before I started. We reminisced about the simplicity of this cake and the star of the show – as you could call it – being the custard. Well, it wasn’t the star due to being perfect – not by any standard. We both remembered a slightly clumpy, neon pink sugary mess. However, there is nothing quite like it really! I’ll have to try and make it next time I bake this.
Retro school sprinkle cake wasn’t the only dessert we had in primary, but it was my favourite of the tray bakes. I also remember a dry chocolate cake with the lumpy custard, but chocolate form this time, and a coconut jam sponge with yellow custard. Do you remember any of these? I feel the sprinkles cake was the most common of the lot.
The best part about this traybake though? They are such simple bakes that you can easily create them at home! Who doesn’t want to re-live their childhood memories of cakes and all things sweet? If you have leftover sprinkles – you could even try my funfetti vanilla cupcakes too.
As this is such a quick and easy bake, you can whip it up on the fly to have as a treat to yourself or to share with friends and family. It is a classic that I know everyone will love. Plus – sprinkles make everything so fun.
Don’t have sprinkles? You can top this with anything – or even keep it plain. I also remember it often having pink icing too, quite like a Tottenham cake. You could easily create this with a few added drops of food colouring. I try to keep my recipes simple so you can have a play and add your own flare. Why not have a go with this one?

To make the vanilla sponge
- Pre-heat the oven to 180°C (conventional) or 160°C (fan)
- Line the baking tray with greaseproof paper and set aside

- Add the eggs into the bowl, one at a time, and mix with the creamed butter until combined
- Add in the vanilla extract and milk and mix again
- Using a sieve, add in the flour in portions and mix in until well combined (adding the flour in slowly gives a smoother texture)
- Pour the batter into the lined baking tray and use a spatula to even out the top of the mix
- Place in the oven and bake for 25-30 minutes (until a toothpick/knife comes out clean and the sponge turns slightly golden)
- Leave the cake in the tin to cool for 15-20 minutes before moving to a wire rack to cool completely
To make the icing and decoration

- Cut the cake into 12 equal portions and enjoy!
