If you’ve grown up in the UK, you’ll probably remember “school cake”. That soft vanilla sponge topped with icing and bright sprinkles was a proper classic, and it’s one of those bakes that instantly brings back memories.
The best part is how simple it is. There’s nothing complicated about it, no fancy ingredients, and no tricky steps. It’s just a light sponge, a layer of icing, and a handful of sprinkles on top.
This is the kind of recipe that’s perfect for busy days, baking with kids, or when you just want something easy that you know everyone will enjoy.
Why This Recipe Works So Well
School cake is popular for a reason. It’s soft, light, and not overly sweet, which makes it ideal for both kids and adults.
It’s also incredibly easy to make. The ingredients are simple, and the method is straightforward, so you don’t need much experience to get it right.
Because it’s a traybake, you can cut it into as many pieces as you need, making it great for sharing, lunchboxes, or keeping in the cupboard for a few days.
Ingredients
For the cake:
- 200g self-raising flour
- 200g caster sugar
- 200g butter or margarine (softened)
- 4 eggs
- 1 tsp vanilla extract
For the icing:
- 200g icing sugar
- 2–3 tbsp water
For the topping:
- Sprinkles (the more colourful, the better)
Method
- Start by preheating your oven to 180°C (160°C fan) and lining a rectangular baking tin with baking paper.
- In a large bowl, cream together the butter and sugar until light and smooth. It doesn’t need to be perfect, just well mixed.
- Add the eggs one at a time, mixing in between each one. Stir in the vanilla extract.
- Fold in the self-raising flour until everything is combined and you have a smooth batter. Try not to overmix as this can affect the texture.
- Pour the mixture into your prepared tin and spread it out evenly.
- Bake for around 25 to 30 minutes, or until the sponge is golden and a skewer inserted into the centre comes out clean.
- Leave the cake to cool completely before adding the icing.
- To make the icing, mix the icing sugar with a small amount of water until you get a smooth, spreadable consistency. It should be thick enough to sit on top without running off the sides.
- Spread the icing over the cooled cake, then add your sprinkles straight away so they stick.
- Leave it to set before cutting into squares.
Tips for the Perfect School Cake
Getting that classic school cake feel is all about keeping things simple.
Make sure the cake is completely cool before adding the icing, otherwise it can melt and slide off.
Don’t add too much water to the icing at once. It’s easier to add a little at a time than to fix it if it becomes too runny.
If you want to change things slightly, you can swap the sprinkles for chocolate chips or leave them off completely for a more basic version.
How to Store School Cake
Once your cake is set and sliced, store it in an airtight container at room temperature.
It will usually stay fresh for around 3 days, although it rarely lasts that long in most households.
You can also freeze the sponge without icing if you want to make it ahead of time.
Final Thoughts
School cake is one of those bakes that proves simple is often best. It’s quick to make, easy to customise, and always goes down well.
Whether you’re baking for your family, making something for a get together, or just fancy a bit of nostalgia, this recipe is a great one to have on hand.
Once you’ve made it, you’ll see why it’s been a favourite for so many years.
