Preparation Steps

• Preheat your oven to 350°F (180°C) and line a rectangular baking tin with parchment paper.
• In a large bowl, cream the softened butter and caster sugar together until light and fluffy.
• Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
• Gently fold in the self-raising flour alternately with the milk until a smooth batter forms.
• Pour the batter into the prepared baking tin and smooth the top with a spatula.
• Bake for 25-30 minutes, or until a skewer inserted into the center comes out clean. Allow to cool completely in the tin.
• To make the icing, sift the icing sugar into a bowl and gradually stir in the boiling water until you reach a spreadable consistency.
• Spread the icing evenly over the cooled cake and scatter with sprinkles. Cut into 12 even slices to serve.
