- Preheat your oven to 180°C.
- Grease and line a 30x20cm (12x8-inch) rectangular baking tin with a depth of at least 6cm (2 inches).
- Using an electric mixer, cream the margarine and sugar together until light and fluffy.
- Add the eggs, vanilla extract, and milk to the bowl. Sift in the flour and baking powder.
- On the slowest speed, mix the ingredients until they begin to combine, then increase the speed and beat for around 1 minute, ensuring the batter becomes smooth.
- Pour the batter into your prepared tin and smooth the surface with a knife or spatula.
- Bake for 30-35 minutes or until the cake is golden and a skewer inserted into the centre comes out clean.
- Leave the cake to cool completely in the tin, then flip it over so the base is facing upwards. Peel away the baking paper.

Add the icing sugar into a bowl with just enough water to create a smooth consistency. It should be spreadable but not runny.
- Pour the icing over the cooled cake and spread it out evenly. Top generously with sprinkles.
- Allow the icing to set for 30 minutes before slicing the cake into portions.
Serve your Old School Sponge Cake as is or add a hearty drizzle of custard for the ultimate nostalgic treat.
