This simple, nostalgic School Cake Sprinkle Sponge is the ultimate comfort food dessert, served with lashings of homemade vanilla custard.
At room temperature, leftover sponge should be good for up to 3 days, loosely wrapped in food wrap to keep things soft and moist. We think custard is best eaten just when it's made but you can keep it in the fridge to gently warm through for another day or so, laying a piece of food wrap on the surface to prevent a skin forming.
