Serve up some nostalgia with this old School Cake, which is simply a fluffy vanilla sponge covered in icing and hundreds of sprinkles! Enjoy it alone or with hot custard, like the good old days.
School Cake goes by a few names, including Sprinkles Cake, Retro School Cake, School Dinner Cake, Old School Cake and more. After our main meal at school, it was traditionally served as a pudding with hot custard.
I would like to say that I had fond memories of school dinners, but unfortunately my time was before Jamie Oliver came in and shook everything up. But a good old sponge tray bake, loaded with sprinkles, was and still is one of my favourites.

Step by Step Instructions
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.
Step 1. Start by creaming the butter and sugar together with an electric mixer. You want it to be pale and creamy. I use a handheld mixer, and it usually takes a couple of minutes.
Steps 2. Add the eggs, one at a time, and beat well. The mixture may split, but will come together later on and doesn't affect the cake.
Steps 3-4. Sift in the flour and gently fold it into the batter until you can't see any flour left. Don't over mix, or the cake will be dense. Scoop the batter into the tin and level the top with a spoon. Bake for 40 minutes until golden, and a skewer inserted into the middle comes out clean.
How to Decorate
When the cake is baked, leave it in the tin for 10 minutes to cool down. After 10 minutes, carefully turn the cake out on a wire rack to cool completely.
To make the icing, add a little water to the icing sugar so it is runny enough to pour. Place some baking paper on a large tray, then place the rack with the cake on it to catch any dribbles.
Pour the icing over the cake and sprinkle generously with sprinkles. Leave to set before cutting into portions.
Variations and Serving Suggestions
For pink icing, add a drop of red or pink food colouring. School cake is typically served with custard, and you can make the custard pink by adding a small drop of food colouring.
FAQs and Expert Tips
Store in an airtight container at room temperature and consume within three days.
Yes, put it in the freezer for 1-2 hours or until the icing is hard. Remove from the freezer and cover the cake with 2 layers of plastic wrap. Return to the freezer and freeze for up to 3 months.

For the Icing and Sprinkles

- Leave the cake on the wire rack and place it over a baking tray lined with baking paper to catch any dribbles. Drizzle the icing over the cake until it's completely covered, and generously sprinkle over the sprinkles. Leave to set, then cut into slices.
